The annual Virginia Geological Research Symposium is an event I enjoy attending. It is typically held in April and is approved for the FMN Better Impact continuing education requirement. It is presented at a professional level and is a conference from which one can acquire valuable knowledge if working in the associated engineering and science fields. Moreover, because it is Virginia centric and geology related, it’s a great learning venture for Virginia master naturalists.

The last couple of years the symposium was held virtually, but it normally meets in Charlottesville. It is free and hosted by Virginia Energy, Geology and Mineral Resources. This organization serves as Virginia’s geological survey. The last symposium was held on April 21, 2022. At this symposium, the U.S. Geological Survey gave a couple presentations related to the 2011 Mineral, Virginia 5.7 magnitude earthquake felt over a wide area including Fairfax County (something most of us will remember). The quake was further discussed in the context of the more recent 2020 Sparta, North Carolina 5.1 magnitude earthquake. Other presentations given by the U.S. Geological Survey included Earth MRI geophysical datasets along the fall-line in SE Virginia and NE North Carolina, and the origin of Carolina Bays in the Coastal Plain of Virginia.

The College of William and Mary had several presenters too. Topics included:

  • Age and origin of the Albemarle-Nelson mafic-ultramafic complex in the eastern Blue Ridge.
  • Structural geology and geochronology of the Shores Melange in the Piedmont.
  • Geology of the Schuyler 7.5-minute quadrangle in central Virginia and understanding Iapetan rifting, sedimentation, and magmatism.
  • Petrology, structure, and geochronology of the Oakville metavolcanic sequence and the implications for the provenance of the Smith River Allochthon.

Of particular interest to me was the landslide hazard mapping in western Albemarle and Nelson Counties by Virginia Energy. I once attended a geologic field trip to Nelson County, the location hit hard by Hurricane Camille in 1969 through the devastating flooding and landslides caused by the hurricane. Another interesting topic was on geologic storage potential in Virginia, also by Virginia Energy.

James Madison University and Radford University students made presentations too.

It is worth exploring the Virginia Energy website at https://www.energy.virginia.gov/. The website features such links as “Ask a Geologist” and information on the geology and mineral resources of Virginia at https://www.energy.virginia.gov/geology/geologymineralresources.shtml.

This symposium is a wonderful resource among many available for geology enthusiasts in Fairfax County. Others include are:

  • The Northern Virginia Mineral Club: https://www.novamineralclub.org/
  • The Annual Gem, Mineral and Fossil Show at George Mason University
  • NVCC 1-day 1-credit excursions (Field Studies in Geology under GOL-135)
  • The Virginia Geological Field Conference (also with counterparts in PA, NJ, and NY)https://vgfc.blogs.wm.edu/

Join FMN Don Coram, instructor, for a course on dragonflies covering their beauty, physiology, behavior, ecological role, and identification. The course includes a classroom presentation followed by a field trip to identify and count dragonflies in Reston. The count is part of an ongoing data collection effort that began in 2009. Although they do count and record the dragonflies that they observe, most of the participants are still learning about dragonflies, and the count is more of an educational field trip than a scientific wildlife survey.

7-8 pm
Register here.

For more than three decades, the Anacostia Watershed Society (AWS) has been working on recovering the Anacostia River’s ecosystems, especially its natural filters. After decades of restoration, education, and advocacy AWS is seeing a great recovery of the biodiversity of the aquatic ecosystems in the Anacostia River.

Jorge Bogantes Montero, Natural Resources Specialist for AWS, will present a virtual tour of the river and speak about the recovery of this once-neglected urban waterway in the nation’s capital. An in-person field trip and boat ride will take place on Saturday, August 20, 2022 for 20 participants.

Free Trees for Communities

Article and photo by Plant NOVA Natives

As community associations around Northern Virginia ramp up their native tree planting efforts, they are looking around to find ways to make it affordable. Burke Centre resident Craig Willett has solved that problem for his neighbors: all they have to do is fill out a simple form to get a free tree. A member of Burke Centre Conservancy’s volunteer Open Space Committee, Craig has organized a system both for private property and for common land. On private land, residents pick up seedlings from Craig’s house and plant them themselves. On common land, the Trustees of the various clusters put in a request, and Craig and his colleagues will install trees or shrubs either to replace ones that have died or to reforest open areas. You can see him pictured here with fellow volunteer Mike Hathaway, in red.

Trees grow slowly, and they also die slowly. Many neighborhoods around Northern Virginia have been losing their canopy coverage, bit by bit, so that once pleasantly shaded yards and streets where neighbors and children could gather are gradually becoming intolerable as our summer temperatures rise. Communities that wish to reverse this trend are most likely to succeed if they build a long-term routine for tree care and tree replacement into their master plans. Where there is no community association, residents will need to step forward to help each other make a plan.

Burke Centre Conservancy obtains its tree seedlings from Fairfax ReLeaf, a non-profit organization of volunteers who plant and preserve native trees on public and common lands in Northern Virginia. Individual landowners may also request seedlings from Fairfax ReLeaf.

Any community in Fairfax County that owns open space may also apply for free trees from the Fairfax Tree Preservation and Planting Fund. It is not necessary to be a 501(c)3 organization to apply as long as the open space is commonly owned. This is a solid funding source for organizations that want to plant either seedlings or larger trees. The application process looks a little intimidating at first glance because of the long list of requirements, but in fact the required steps are all ones that any organization would take anyway when planting trees.

Programs for obtaining free native trees are also available to communities in Arlington and Falls Church. And although not free, there are numerous ways to obtain native trees for a very low price. For example, the Virginia Department of Forestry sells tree and shrub seedlings for $2.00 apiece for orders of ten or more. Our local native plant garden centers all sell medium-sized trees in containers at reasonable prices. Those trees may look a little small when first planted, but they will rapidly catch up to trees that were planted when larger, since older trees suffer more transplant shock. Two wholesalers of larger trees offer their trees at wholesale cost to people who are organizing community plantings. Links to all these programs can be found on the Plant NOVA Trees website.

Since 2018, Burke Centre Conservancy has planted over 600 bare root seedlings, which is in keeping with the nature-centered philosophy of this community with its extensive network of trails through the woods. More details about their process can be found on this web page.

FMN CE Hike: Herp Hunt on June 26th

Article and photos by FMN Barbara Saffir except as noted

Orange turtles, slinky snakes, and shy salamanders were the highlight and delight of FMN’s first-ever continuing education “Herp Hunt” hike on June 26, 2022.

Thirteen enthusiastic FMNers (including some board members) attended the three-hour hike at Hemlock Overlook Regional Park, including FMN event coordinator, Barbara Saffir, who co-led the hike with two experts (and an assistant expert) from the Virginia Herpetological Society.

Caroline Seitz led one group, taking the “high road” through the hilly park, so to speak.  She’s VHS’s education chair.  VHS’s Mark Khosravi, a science teacher who was recently quoted in the Washington Post discussing venomous copperheads, and his assistant led his hikers on the lower trail.  Both groups “herped” upland wooded areas and lower stretches along the Bull Run stream.

Among their discoveries were: SNAKES (a small ring-necked snake, a queen snake that repeatedly posed in the stream, adult and immature

northern watersnakes, and an eastern worm snake); TURTLES (several male and female woodland box turtles, a red-bellied slider turtle, a painted turtle, and broken turtle eggs); FROGS/TOADS (pickerel frog, adult and baby green frogs, baby wood frog, and Fowler’s toads); and SALAMANDERS/SKINKS (a red-spotted newt, a northern two-lined salamander, a long-tailed salamander, and five-lined skinks).

Woodland box turtle

FMNers even learned how to differentiate male from female box turtles and American toads from Fowler’s toads.  A five-lined skink hopped aboard board member Amy Stulman, who handled the opportunity with a smile. Debbie McDonald spied the first herp of the day on Seitz’s hike, a precious woodland box turtle. We learned to report box turtle sightings to VHS online.

Sunday, September 25, 2022
3 – 5pm
Virtual
Fees: $10 + fees
Register here.

Doug Tallamy is an entomologist, ecologist and conservationist, a professor in the Department of Entomology and Wildlife Ecology at the University of Delaware, and a successful author. Tallamy will deliver a talk for us titled, “Restoring the Little Things that Run the World.” A recent UN report predicts that as many as 1 million species will disappear from planet earth because of human activities. Many of these are insects and nearly all species at risk rely on insects. A world without insects will be a world without humans! So, how do we create beautiful landscapes brimming with life – landscapes that support the butterflies, caterpillars, bees, beetles and other insects that run the ecosystems we depend on? Tallamy will remind us of the essential roles insects play, and describe the simple changes we must make in our landscapes and our attitudes to keep insects on the ground, in the air and yes, on our plants.
