TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the weeks of December 19 and December 26, 2022.  This episode is the last in a series this year of episodes related to trees and shrubs. MUSIC – ~16 sec – instrumental. That's part of “Fair Meadows and Goodly Tall Trees,” by Timothy Seaman, of Williamsburg, Virginia, on his 2006 album, “Jamestown: On the Edge of a Vast Continent.”  Across that vast continent, from the Chesapeake Bay to forested western states, people recognize that “goodly tall trees,” as well as shorter trees and shrubs—in woods, parks, yards, and built areas—affect water resources in many important ways.  Have a listen to the music for about 30 more seconds and see if you can think of some of those ways. MUSIC  - ~30 sec – instrumental. If you thought of tree impacts on water supplies, aquatic habitat, or the physical or chemical quality of water, you're right!  Such impacts frequently provide benefits to humans, and those benefits are often called “ecosystem services.”  Here are five examples of water-related services that trees provide to human societies. 1.  Trees can slow or reduce stormwater runoff by intercepting precipitation, by transpiration (that is, the evaporation of water from leaves), and by increasing infiltration of water into the ground. 2.  Trees can improve water quality through reducing sediment inputs to waterways, when they slow runoff speed so that more sediment settles out, and when they hold soil in place at streamsides and in uplands. 3.  Trees can also improve water quality through uptake of plant nutrients that otherwise would remain in soil or water; excessive nutrients can degrade aquatic ecosystems and impair groundwater quality. 4.  Trees living on shorelines, and woody debris in waterways, provide food, habitat, and temperature regulation for aquatic ecosystems. And 5.  Trees can help reduce climate changes, with their many water-related aspects, through the uptake of carbon dioxide in photosynthesis and through reduction of human energy use by shading in hot weather and wind breaks in cold weather. In some cases, though, trees can have water-related impacts that are not positive for humans.  For example, tree use of water in some situations can reduce stream flows that provide water supplies, especially in summer; and in western states that depend on snowpack for water supply, trees may either increase or decrease the available snowpack, depending on several factors. Such circumstances remind us that trees exist for their own survival and reproduction, not for human benefit; nevertheless, those long-living, photosynthesizing, woody, and goodly tall beings do provide human beings with irreplaceable benefits. Thanks to Timothy Seaman for permission to use this episode's music, and we close out the episode—and our series on trees and shrubs—with the final 20 seconds of “Fair Meadows and Goodly Tall Trees.” MUSIC  - ~22 sec – instrumental.

EXTRA INFORMATION ABOUT WATER-RELATED BENEFITS OF TREES The following information is from the Virginia Department of Forestry, “Benefits of Trees,” online at https://dof.virginia.gov/education-and-recreation/learn-about-education-recreation/benefits-of-tree/, as of 12-19-22. “Trees in Forests: Forests are well known for providing a renewable source of wood products. Some products come from the trees themselves, while others, like mushrooms or medicinal herbs, come from the forested environment. In addition to lumber, paper, and a host of other products, forests provide benefits called ‘ecosystem services,' including filtering air to improve air quality; preventing soil erosion; supplying places for outdoor recreation; providing wildlife and pollinator habitat; sequestering and storing carbon; protecting water quality; offering scenic beauty.”  “Trees in Cities and Towns: Trees in urban areas and yards have value, too. Neighborhoods with lots of trees have lower crime rates, less air pollution, lower energy costs, and higher property values than those without trees. Walking among trees can improve health, and even viewing trees through a window can speed patient recovery times.” “Trees in Riparian [Streamside] Areas: Trees in riparian, or streamside, zones provide special ecosystem benefits, including: filtering runoff to remove pesticides, fertilizer, and other chemicals; preventing streambank erosion and keeping sediment out of the stream; shading streams to keep them cool for aquatic organisms; dropping organic matter that serves as food and microhabitat for aquatic organisms; [and slowing] water during storm events....reducing flood potential.”   (This image was also including in the Show Notes for Virginia Water Radio Episode 621, 3-21-22, the introductory episode in the series on trees and shrubs.)SOURCESUsed for AudioAlliance for the Chesapeake Bay, “Forests,” online at https://www.allianceforthebay.org/forests/.

Unless otherwise noted, all Web addresses mentioned were functional as of 10-28-22. TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio, with a special episode for Halloween 2022.  This episode is part of series this year of episodes related to trees and shrubs. SOUND – ~5 sec and fade - Tree creaking in wind. Creaking wood is often part of a scary Halloween soundscape of dark forests or old houses.  Does that creaking have anything to do with water?  That's one of five questions this episode poses, challenging you to make connections among Halloween, tree parts, and water.  After each question, you'll have about three seconds of some Halloween music to consider your answer.  Good luck, and I hope you do TREE-mendously. No. 1.  Scary human skeletons are a common Halloween feature.  In humans and other animals, skeletons support the body.  What part of trees, through which water and nutrients are transported, functions as the trees' structural support?  MUSIC - ~3 sec.  That's the xylem, also called the wood, which makes up the bulk of a tree trunk. No. 2.  Blood is a featured in many a frightful Halloween scene or costume.  Blood is a water-based fluid that humans and other animals use to transport oxygen, energy molecules, and other biochemicals to body parts.  What part of the tree carries energy molecules and other biochemicals to tree parts?  MUSIC - ~3 sec.  That's the phloem, which makes up a relatively thin layer just under a tree's bark. No. 3.  Ghosts or other specters are often depicted in white or black.  How do light and dark colors affect water in a tree?  MUSIC - ~3 sec.  Dark colors in or around trees absorb more solar radiation and therefore can increase temperature.  The light color or some trees, such some birches, can help reduce this effect.  Temperature, along with humidity, affects water movement into and out of trees, particularly by affecting transpiration, that is, the evaporation of water from plant parts. No. 4.  Wind whistling through trees is weather people often associate with Halloween nights.  How does wind affect the water in a tree?  MUSIC - ~3 sec.  Wind can increase transpiration both by bringing drier air to leaves and by moving away air that has absorbed moisture from the leaves. And no. 5.  Back to creaking wood.  How does water or dryness affect sounds in wood?  MUSIC - ~3 sec.  In wooden houses, creaking can result from temperature and humidity changes that swell or shrink the wood.   In trees, a crackling or popping sound—detected by scientists using microphones placed next to tree trunks—can result from air bubbles within the tree trunk, caused by tree dehydration.  Incidentally, frequent creaking sounds in trees may be an indicator of weak tree structure, so a creaking tree sometimes not only sounds scary but also is reason to be wary. I hope your Halloween this year and in years to come includes fun and functional trees along with adequate good water for them and for you.  We close with the full 50 seconds of the Halloween music you've heard during the questions.  Here's “A Little Fright Music,” composed for Virginia Water Radio by Torrin Hallett, currently with the Symphonic Orchestra of the State of Mexico. MUSIC – ~50 sec – instrumental. SHIP'S BELL Virginia Water Radio is produced by the Virginia Water Resources Research Center, part of Virginia Tech's College of Natural Resources and Environment.  For more Virginia water sounds, music, or information, visit us online at virginiawaterradio.org, or call the Water Center at (540) 231-5624.  Thanks to Stewart Scales for his banjo version of “Cripple Creek” to open and close this episode.  In Blacksburg, I'm Alan Raflo, thanking you for listening, and wishing you health, wisdom, and good water.

TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the weeks of October 24 and October 31.   This revised episode from Halloween 2014 is part of a series this year of episodes related to trees and shrubs. SOUNDS – ~9 sec What better than an Eastern Screech-Owl calling eerily from a dark woods to conjure up a Halloween landscape? But for this Halloween season episode, consider a much quieter, but still mysterious, part of that landscape: the American Witch Hazel plant.  This shrub or small tree—a native in Virginia and throughout the eastern United States—has two noteworthy water connections.  First is the use of its forked twigs in “dowsing,” “divining,” or “water witching” to try to find groundwater, a centuries-old practice that some people still follow.  In fact, the “witch” in the plant's common name may derive from an old English word that means “bend,” apparently referring to the plant's flexible twigs and, perhaps, to the belief that a dowsing rod will bend toward groundwater.  Second, extracts from the plant's bark and leaves have long been used—medicinally and cosmetically—as an astringent, that is, a substance used to dry fluids and shrink tissues. Besides its reputed water-finding ability and its established fluid-drying uses, American Witch Hazel is also remarkable for its unusual blooming time.  Bright yellow flowers appear in fall and can continue into December, often seen beside fruits from the previous season.  When those fruits ripen, seeds are forcibly ejected some distance, leading to yet another possible origin of the plant's name: that people attributed to witchcraft the mysterious sound of those far-flung seeds hitting the ground. From its name, to its uses, to its unusual flowering and fruiting, Witch Hazel offers botanical treats far beyond Halloween season's creepy screeches. SOUND – 3 sec – Screech-Owl We close a musical observation about how seeing a cold-weather flowering tree can inspire human resilience.  Here's about 50 seconds of a song called “Witch Hazel,” by Tom Gala, from his 2011 album, “Story After Story.” MUSIC - ~53 sec – Lyrics: “I am looking at Witch Hazel blooming in a garden—the bright yellow flowers in the middle of wintertime.  And I tell my heart be strong like the Witch Hazel flower, and you will not be injured by this dark and trouble time.” SHIP'S BELL Virginia Water Radio is produced by the Virginia Water Resources Research Center, part of Virginia Tech's College of Natural Resources and Environment.  For more Virginia water sounds, music, or information, visit us online at virginiawaterradio.org, or call the Water Center at (540) 231-5624.  Thanks to Ben Cosgrove for his version of “Shenandoah” to open and close this episode.  In Blacksburg, I'm Alan Raflo, thanking you for listening, and wishing you health, wisdom, and good water.

EXTRA INFORMATION ABOUT WATER DOWSING The following information is quoted from the U.S. Geological Survey, “Water Science School/What is Water Dowsing?”; online at https://www.usgs.gov/special-topics/water-science-school/science/water-dowsing. “'Water dowsing' refers in general to the practice of using a forked stick, rod, pendulum, or similar device to locate underground water, minerals, or other hidden or lost substances, and has been a subject of discussion and controversy for hundreds, if not thousands, of years. “Although tools and methods vary widely, most dowsers (also called diviners or water witches) probably still use the traditional forked stick, which may come from a variety of trees, including the willow, peach, and witchhazel.  Other dowsers may use keys, wire coat hangers, pliers, wire rods, pendulums, or various kinds of elaborate boxes and electrical instruments. “In the classic method of using a forked stick, one fork is held in each hand with the palms upward.  The bottom or butt end of the ‘Y' is pointed skyward at an angle of about 45 degrees.  The dowser then walks back and forth over the area to be tested.  When she/he passes over a source of water, the butt end of the stick is supposed to rotate or be attracted downward. “Water dowsers practice mainly in rural or suburban communities where residents are uncertain as to how to locate the best and cheapest supply of groundwater.  “Because the drilling and development of a well often costs more than a thousand dollars, homeowners are understandably reluctant to gamble on a dry hole and turn to the water dowser for advice.” What does science say about dowsing? “Case histories and demonstrations of dowsers may seem convincing, but when dowsing is exposed to scientific examination, it presents a very different picture.  The natural explanation of ‘successful' water dowsing is that in many areas underground water is so prevalent close to the land surface that it would be hard to drill a well and not find water.  In a region of adequate rainfall and favorable geology, it is difficult not to drill and find water! “Some water exists under the Earth's surface almost everywhere. This explains why many dowsers appear to be successful.  To locate groundwater accurately, however, as to depth, quantity, and quality, several techniques must be used.  Hydrologic, geologic, and geophysical knowledge is needed to determine the depths and extent of the different water-bearing strata and the quantity and quality of water found in each.  The area must be thoroughly tested and studied to determine these facts.”SOURCES Used for Audio John-Manuel Adriote, “The Mysterious Past and Present of Witch Hazel,” by The Atlantic, November 6, 2012, online at http://www.theatlantic.com/health/archive/2012/11/the-mysterious-past-and-present-of-witch-hazel/264553/.American Water Surveyors, “Water Witching: A Brief History,” by Gerald Burden, December 26, 2015, online at https://wefindwater.com/water-witching-a-brief-history/.

TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the weeks of October 10 and October 17, 2022.  This revised episode from October 2015 is part of a series this year of episodes related to trees and shrubs. MUSIC – ~12 sec – instrumental. In this episode, we feature music about an annual turning point that inspires humans but shuts down trees.  Have a listen for about 40 seconds. MUSIC – 40 sec – Lyrics: “Leaves turn green and then grow bright to every color, every type, and finally in the wind let go, to fall and paint the earth below.  Roots so deep, the trunk so high, her arms reached up into the sky; through her veins all colors run from everywhere to everyone.” You've been listening to part of “Colors,” by John McCutcheon, on his 1998 album “Four Seasons: Autumnsongs,” from Rounder Records.  Prior to moving to Atlanta in 2006, Wisconsin native John McCutcheon was a long-time resident of Charlottesville, Virginia.  The song's full lyrics describe a growing appreciation of the variety of fall leaf colors and their power to inspire and invigorate people.  But for deciduous trees—that is, those that lose all of their leaves annually—autumn colors and falling leaves are signs of internal changes leading to the relative inactivityof winter dormancy.  Reduced water movement is one of the key changes.  Leaf drop follows the sealing off of a leaf's veins from the stem vessels that carry water and dissolved materials to and from the leaf during the growing season.  During that growing season, evaporation of water from leaves—called transpiration—and the cohesion between water molecules are the main driving forces pulling water up from roots through woody stems to the leaves.  This water movement provides tree cells the vital fluid needed for the cells' structures and biochemical reactions that allow survival and growth.  That growth stops during winter dormancy, and water movement is much reduced. After leaf fall, left behind on winter twigs are characteristic marks called leaf scars containing bundle scars showing the previous growing season's points of fluid transfer between stems and leaves.  Above or beside the leaf scars are overwintering buds, harboring the tissues that will become next year's leaves and colors. Thanks to John McCutcheon and Appalseed Productions for permission to use this week's music, and we close with about 20 more seconds of “Colors.” MUSIC – ~23 sec – instrumental.

TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the weeks of September 26 and October 3, 2022.  This episode is part of a series this year of episodes related to trees and shrubs. SOUND – ~6 sec That call of Mountain Chorus Frogs opens an episode where we learn about the video podcast series, “Fifteen Minutes in the Forest.”  Started in April 2020, the video series is produced by the Virginia Forest Landowner Education Program, conducted by Virginia Cooperative Extension.  As of September 9, 2022, the series included 82 episodes, covering topics such as tree identification, forest soils, invasive plants, forest management, tree syrups, and weird trees.  Several episodes are on specific water-related topics, like the Mountain Chorus Frogs you heard earlier.  Have a listen for about 90 seconds to excerpts from five of those episodes.  SOUNDS and VOICES  - 1 min./29 sec “Hi everyone.  Welcome to ‘Fifteen Minutes in the Forest.'  I'm Jennifer Gagnon with the Forest Landowner Education Program at Virginia Tech.  And today I'm joining you from Claytor Lake State Park in southwest Virginia.”  From “Vernal Pools,” Episode 74, April 2022. “This is a vernal pool in Claytor Lake State Park.  ...This pool at its largest is probably an acre in size.  This pool is big enough that it has Painted Sliders, we saw a Snapping Turtle in here, we have a Green Heron out here.  ...There's all kinds of animals. ...It's a beautiful pool.”  From “Vernal Pools,” Episode 74, April 2022.  “Our topic today is going to be about water quality.  And this ties in nicely with forestry.”  From “Best Management Practices for Water Quality,” Episode 19, September 2020. Today we're going to take a look at some of the best management practices that loggers and forestry operations can take in order to protect water quality.”  From “Best Management Practices for Water Quality,” Episode 19, September 2020. “One of the reasons we're studying Mountain Chorus Frogs is we're really trying to get a good idea of their distribution in Virginia.”  From “Mountain Chorus Frogs,” Episode 75, April 2022. “Hey everyone.  My name is Wally Smith, and I'm an associate professor of biology at UVA-Wise.  And we are here on the banks of the Clinch River in St. Paul, Virginia, today to talk about the Eastern Hellbender, which is one of our most unique amphibians here in Virginia and the central Appalachians.”  From “Eastern Hellbenders,” Episode 68, January 2022. “Well thank for spending fifteen minutes in the creek with us, and thanks to Sally for for spending time with us outside to share her knowledge about water quality.  And I hope you join us for another edition of ‘Fifteen Minutes in the Forest.'  Have a great weekend.”  From “How Clean is Your Creek,” Episode 26, November 2020. When COVID shut-downs began in 2020, the Virginia Forest Landowner Education team started the series as a way to stay engaged with clients.  To the team's surprise, the series became very popular.  Among the users are public school teachers, foresters, landowners, and other lovers of the outdoors. Along with the “Fifteen Minutes in the Forest” series, the Virginia Forest Landowner Education Program offers other short courses, conferences and workshops, Fall Forestry and Wildlife Field Tours, and retreats for beginning woodland owners.  For more information about these learning opportunities, search online for the Virginia Forest Landowner Education Program, or phone Jennifer Gagnon at (540) 231-6391. Thanks to Ms. Gagnon for permission to use excerpts of “Fifteen Minutes in the Forest” episodes.  And for a closing forest-and-water word, we end with a comment from Andrew Vinson, of the Virginia Department of Forestry, from the episode on best management practices for water quality.

TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the weeks of May 9 and May 16, 2022.   This episode from is part of a series this year of episodes related to trees and shrubs. MUSIC – ~14 sec – instrumental. That's part of “New Spring Waltz,” by the late Madeline MacNeil, who was a well-known and highly regarded musician based in Virginia's Shenandoah Valley. Each new spring brings a chance to focus on the life cycles of wildlife.  This mid-spring episode of Water Radio explores some connections among nesting birds, trees, and water.  Have a listen for about 30 seconds to three mystery sounds, and see if you know these three bird species who nest in trees near water, either always or at least sometimes.  And here's a hint: you'll be singing a melodious trill, if you hit this mystery out of the park. SOUNDS  - 29 sec. If you guessed two warblers and an oriole, you're right!  And you get bodacious bird bragging rights if you recognized, first, the Prothonotary Warbler; second, the Northern Parula, also a kind of warbler; and third, the bird for which Baltimore's baseball team is named, the Baltimore Oriole.  All three of these songbirds are found in Virginia in the spring and summer breeding season.  During that period, the Prothonotary Warbler is common in Virginia's central and southern Coastal Plain and can occasionally be found in some other parts of the Commonwealth; the Baltimore Oriole is common outside of the Coastal Plain; and the Northern Parula is common statewide.  The three species show a range of attachment to water-side trees as their nesting habitat.  The Prothonotary Warbler is particularly known for nesting in cavities in trees around water; in fact, the bird is sometimes called the “Swamp Warbler” in the southeastern United States.  The Northern Parula typically nests in trees along rivers and wetlands, especially in areas where it can find the materials it prefers for making its hanging nests: Spanish Moss or a kind of stringy lichen; this bird is also known to make nests out of debris left in trees after floods.  The Baltimore Oriole is the least water-attached of these three species, being found nesting high in trees in many areas outside of deep woods, including parks and yards; however, streamsides are among the species preferred areas for the bird's fibrous, hanging nests. If you're near streams, rivers, or wetlands and you see or hear any of these three birds, look to nearby trees for cavities or hanging materials that may be harboring the birds' next generation. Thanks to Lang Elliott for permission to use the bird sounds, from the Stokes Field Guide to Bird Songs.  Thanks also to Janita Baker of Blue Lion Dulcimers and Guitars for permission to use Madeline MacNeil's music, and we close with about 25 more seconds of “New Spring Waltz.” MUSIC – ~26 sec – instrumental.

TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the weeks of April 25 and May 2, 2022.  This episode is part of a series this year of episodes related to trees and shrubs. MUSIC – ~12 sec – instrumental. This week, that excerpt of “Baldcypress Swamp,” by Timothy Seaman of Williamsburg, Va., sets the stage for exploring some of Virginia's tree species found in or near water, along with some of the water places those trees inhabit.  We start with a series of guest voices calling out 16 native Virginia tree species that can be found around watery habitats.  Have a listen for about 25 seconds. VOICES and INSTRUMENTAL MUSIC - ~27 sec - “American Sycamore.  Atlantic White-cedar.  Baldcypress.  Black Gum.  Black Willow.  Boxelder.  Eastern Hemlock.  Hackberry.  Overcup Oak.  Red Maple.  Red Spruce.  River Birch.  Silver Maple.  Swamp Tupelo.  Water Hickory.  Water Tupelo.” Those 16 and other tree species can be found in a wide variety of water-related habitats in Virginia.  The Virginia Department of Conservation's 2021 report, “The Natural Communities of Virginia: Ecological Groups and Community Types,” lists over 30 community types associated with aquatic habitats.  Tree species are a characteristic of the vegetation in over 15 of those community types, ranging from Piedmont/Mountain Small-stream Alluvial Forests, to Coastal Plain/Piedmont Bottomland Forests, to Coastal Plain Depression Swamps and Ponds, to Maritime Swamps.  More generally speaking, you can find native Virginia trees beside small streams in uplands, for example, Eastern Hemlock; beside large rivers in the mountains or Piedmont, for example, American Sycamore and Silver Maple; beside large Coastal Plain rivers, for example, Overcup Oak and Water Hickory; and in a variety of swamps and other wetlands, for example, Baldcypress, Atlantic White-cedar, and Swamp Tupelo. Here's to Virginia's many tree species, its many water habitats, and the many combinations of those two groups of natural resources.  Thanks to seven Virginia Tech colleagues for lending their voices to this episode.  Thanks also to Timothy Seaman for permission to use this week's music, and we close with about 15 more seconds of “Baldcypress Swamp.” MUSIC – ~15 sec – instrumental.

TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of April 18, 2022.  This update of an episode from July 2017 is part of a series this year of episodes related to trees and shrubs. MUSIC – ~14 sec That's part of “The Ash Grove,” a traditional Welsh tune performed by Madeline MacNeil, on her 2002 album, “Songs of Earth & Sea.”  Born in Norfolk and raised in Richmond, Ms. MacNeil was a well-known and highly regarded musician based in Virginia's Shenandoah Valley until her passing in 2020. The music opens an episode where we revisit the status of North American ash trees and explore the water impacts of pest damage to trees generally. As noted in the July 2017 episode on ashes, North America is home to 16 native ash species, with six of those occurring naturally in Virginia.  The two most common ash species in Virginia are White Ash, which tends toward upland habitats, and Green Ash, which is often found along streams and rivers.  In those areas, Green Ash can be a significant portion of the vegetation and help create habitats, improve water quality, and stabilize flows.  Both species provide food for a variety of animals and both have been widely planted in cities and towns. Since the early 2000s, ash tree populations have been devastated by the spread of the Emerald Ash Borer, a beetle native to Asia.  As of April 2022, the insect had been found in at least 35 states and the District of Columbia, and in nearly all of Virginia.  In an affected tree, the insect's larvae create a network of tunnels that impair the tree's transport of water and nutrients, eventually killing the tree.  Once an area's invaded, ashes are unlikely to survive for more than a few years without expensive chemical treatment of individual trees.  At the scale of whole forests, researchers and managers are exploring the use of parasitoid wasps as a biological control method. The Emerald Ash Borer is only one of many pest species threatening different trees in Virginia and elsewhere.  Several of these pests have been the subject of research on their water-related, or hydrologic, impacts.  Researchers are interested in how loss of tree leaves or death of trees can affect evaporation, soil moisture, water-table levels, streamflows, water chemistry, and snowpack.  Those water-cycle processes are in turn connected to ecosystem pathways of carbon, nutrients, and energy, all being affected by climate changes.  From all of these connections, little ash-boring beetles become part of a biosphere-sized story. Thanks to Janita Baker of Blue Lion Dulcimers and Guitars for permission to use Madeline MacNeil's music,” and we close with about 25 more seconds of “The Ash Grove.” MUSIC – ~24 sec – instrumental.

From Background Tab: “After only 1-5 years of infestation, the larvae create extensive tunnels under the bark that disrupt the tree's ability to transport water and nutrients, which eventually girdles and kills the tree. The length of this process depends on tree age, health, and EAB density in the area but no ash tree is safe - 99% of infested ash will die.” From Distribution Tab: “In the U.S., EAB targets 16 species of native ash trees (Fraxinus spp.) and white fringetree (Chionanthus virginicus).  In Virginia, white ash (Fraxinus americana) and green ash (Fraxinus pennsylvanica) are the most commonly found, though there are four other species that have limited ranges (pumpkin, black, blue, and Carolina ash). In the wild, ash often prefers wetter environments and are dominant species along rivers and streambanks.  Ash decline and death may have a negative impact on streambank stabilization and waterways in these rural areas.  Though only a small percentage of Virginia's forests are composed of ash (2-3%), urban areas can have tree inventories tallying up to 13% ash.  This is where dead ash poses the most risk!” From Biological Control Tab: “Biological control (or “biocontrol”) is a management strategy that involves releasing natural enemies from the pest's native range to control the pest at a given location.  Researchers identified wasps in the early 2000s from Eastern Asia that had co-evolved with emerald ash borers as a parasite to control its populations.  They then conducted extensive research in quarantined U.S. labs to study their life cycle, environmental parameters, and host species.  After nearly a decade of trials, only four wasp species passed the strict requirements set by the USDA-APHIS (Animal and Plant Health Inspection Service) and were approved for release.  APHIS now rears these wasps in large quantities then collaborates with federal, state, and local governments, as well as land owners to release them at approved sites.  These tiny stingless wasps lay eggs in EAB eggs or larvae, effectively killing the EAB host, and are commonly called “parasitoids.” ...These wasps do not harm humans in any way, they only target emerald ash borer as a host. The use of these biocontrol agents in suppressing EAB has shown promising results, but it will take years of controlled releases and research before we see successful parasitism and a reduction of the EAB population.” SOURCES Used for Audio Samuel H.

TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of April 4, 2022.  This revised episode from May 2013 is part of a series this year of episodes related to trees and shrubs. MUSIC – ~ 16 sec – Lyrics: “Lost my fingers in the Galax mill, Buddy sing a sad old song; And my heart got broke in the yew pine hills, Lordy my time ain't long.” This week, we feature music about some historical aspects of a natural-resource industry that's been important to Virginia's economy for hundreds of years and also plays an important role in managing the Commonwealth's water.  Have a listen for about 30 more seconds.MUSIC – ~31 sec – Lyrics: “I started out to loggin' when I was in my prime, Woman don't you weep for me; Hitchin' up the spruce to the big drag lines, You damned old piney mountain; Where the skidders start a-buckin' as the years come down, Buddy sing a sad old song; Makin' God's own thunder on the new-cut ground, Lordy my time ain't long.” You've been listening to part of “Piney Mountains,” by Bruce Molsky on his 2013 album, “If It Ain't Here When I Get Back,” from Tree Frog Music.  The song was written by Craig Johnson, a highly-regarded string-band musician who died in North Carolina in 2009.  Focusing on one logger-turned-millworker's tragic accident in a Galax, Virginia, mill, the song weaves in several aspects of the history of the forest industry in the southeastern states: hard work and rough leisure by loggers, opportunities and risks of working in sawmills and furniture factories, economic ups and downs of resource-based industries, changes to landscapes after land uses change, and a rich heritage of traditional music. With a complex history, forest use and management in Virginia remains of vital economic and ecological importance, including for water resources.  As the Virginia Department of Forestry has stated, quote, “In addition to lumber, paper, and a host of other products, forests provide benefits called ‘ecosystem services,'” unquote.  Those services include air quality, water quality, soil conservation, outdoor recreation, wildlife habitat, carbon storage, and scenic beauty. As of 2017, over 16 million acres in Virginia—about 62 percent of the state—were covered by forests, and those forests provided an estimated $30 billion annually in economic benefits, considering both forest products and ecosystem services.  At the same time, forest-related work can still be hazardous, as it was for the narrator in this week's music.  Logging, for example, typically has higher workplace injury and fatality rates than other occupations. With connections and impacts like these, piney mountains and other wooded landscapes will continue to influence Virginia's economy, culture, wildlife, air, and water. Thanks to Bruce Molsky for permission to use this week's music, and we close with about 15 more seconds of “Piney Mountains.” MUSIC – ~ 16 sec – instrumental.

TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of March 28, 2022.  This revised episode from December 2018 is part of a series this year of episodes related to trees and shrubs. MUSIC – ~ 10 sec – instrumental. This week, that excerpt of “Hiking in the Highland Firs,” by Timothy Seaman of Williamsburg, Va., opens an episode on a woody plant structure that's closed during wintertime and whose opening is a mark of spring.  Have a listen for about 15 seconds to some of the weather that trees and shrubs endure during a Virginia winter, and see if you can guess this structure.  And here's a hint: if you don't know this, you might ask a buddy. SOUNDS  - ~15 sec – March wind in previous year's oak leaves.If you guessed tree and shrub buds, you're right!  Buds are one of woody plants' adaptations for surviving winter's cold temperatures, drying conditions, and damaging winds.  Buds contain meristematic tissue, the tissue that will be future growing stems or flowers.  Sometimes woody plant buds include only the meristematic tissue, but more typically that tissue is covered by small, folded leaves and modified leaf structures called bud scales.  Just like tree and shrub leaves, buds have distinctive shapes and colors, often allowing identification when leaves are gone. Flowering trees and shrubs form both vegetative and flower buds.  The vegetative buds can be at the end of twigs or along the length of twigs in the axils where leaves attach.  Flower buds may look very different from vegetative buds, for example, as in the Flowering Dogwood.  Non-flowering trees and shrubs—that is, conifers, the cone-bearing woody plants, such as pines, spruces, and firs—also have vegetative buds that can develop into stems or into cones. In temperate climates, buds typically form at some point during the growing season and then become dormant—that is, stop actively growing—during the winter.  In spring, in response to hormones and environmental conditions, bud dormancy ends as the buds open and the enclosed tissues begin developing and growing.  But there's much variation among species, and even among individuals within a species, in patterns and timing of bud formation, dormancy, and activity. Now, what makes woody plant buds particularly a water story?  Here are three answers to that question. First, the availability of water during bud formation in one year can affect how much tissue is stored in the bud for growth and development the following spring.  Second, the meristematic tissue in a bud is protected from drying out by the covering bud scales and undeveloped leaves.  And third, while buds don't protect plant cells from freezing, their role in preventing dehydration contributes to the plant's ability to withstand injury from freezing temperatures. As spring unfolds in Virginia, some do the buds on the Commonwealth's woody plants, revealing some of the history—and water—of last summer, along with the future of this year's growing season.

TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of March 21, 2022.  This revised episode from March 2013 is the first in a series of episodes this year on trees and shrubs. MUSIC – ~7 sec – instrumental. This week, we feature a musical selection about one of Virginia's most common natural resources and one of the most important for the Commonwealth's waters.  Have a listen to the music for about 45 more seconds.  MUSIC  - ~43 sec – Lyrics: “When you plant trees, it's not for tomorrow; no shade tomorrow from them itty bitty seeds.  It's your children's children who'll look up and feel the wonder; it's like lovin' some person you might never chance to meet.  You could say it with flowers, you could shout it from the rooftop, you could beg from your knees; you could say I'm sorry, or darlin' I love you—Grandad planted trees.” You've been listening to part of “Grandad Planted Trees,” by Bob Gramann of Fredericksburg, Virginia.  Fortunately for all of us, lots of people these days are like the grandad in the song and recognize the value of planting trees for many reasons, including water benefits.  Here are four examples: volunteers in many watersheds plant trees along streams to help improve water quality and habitat; cities encourage tree-planting to help reduce stormwater runoff and the pollutants it can carry to waterways; Chesapeake Bay states are working to increase forest coverage to improve Bay water quality, such as in the Virginia Department of Forestry's Virginia Trees for Clean Water Program; and 141 countries at the U.N. Climate Change Conference in 2021 affirmed the critical role of trees in addressing climate change through trees' absorption of carbon dioxide during photosynthesis.  In these and other ways, trees are recognized as part of the solution for an array of water-resources issues. Virginia has a rich diversity of trees: deciduous and evergreen; flowering and cone-bearing; shrubby and towering.  These trees' interactions with water are key factors in the health of water, land, air, and wildlife.  And, of course, trees are great for shade, beauty, and birdsong.

Florida gets a lot of rain, but our natural water cycle is shifting more towards an urban water cycle as we develop the Sunshine State. In this episode of Naturally Florida, we'll be chatting about the impacts of development on the water cycle with a focus on stormwater and its impact on the watershed.

Welcome to the Episode 2 of The Watercourse! My guest today is Chelsea Panos (twitter.com/chelsea_panos), an expert on the stormwater impacts of infill development. What is infill development? It's a nationwide trend of creating more housing in a smaller footprint, so that more people can live closer to cities. Chelsea explains how you might have seen old neighborhoods get converted from small, single family homes with big yards into high density apartment units. What do those changes mean for stormwater management? We're here to find out! In this interview from September 2019, Chelsea teaches me about how infill development affects stormwater runoff and what the city and developers can do to mitigate negative impacts. *Pre-listening resources* Stormwater Primer: youtu.be/LMq6FYiF1mo Bioretention Primer: youtu.be/LiNd2ZaYS2k Infill Development Article (NY Times): nyti.ms/2ZxM6eN Climate Change and Stormwater (Medium): bit.ly/3d0K0YY *Post-listening resources* doi.org/10.1038/s41467-020-15376-9 doi.org/10.1080/23789689.2020.1754625 Also check out Panos et al.
