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.

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).

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.

Virtual
Fees: $10 + fees

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.

Fort Ward’s Maclura pomifera Tree

Feature photo: The arranged fruits of the Osage Orange tree into a happy face caught my attention and consequently initiated my interest to write this article.

Article and photos by FMN Stephen Tzikas

Osage Orange has a tough “stomp-proof” fruit that will not be crushed with foot pressure. It is grapefruit sized, about 4 inches in diameter, with an outer surface that looks like “brains.”

In December 2021, while on a trail review for the Birdability website (https://www.birdability.org/), I came across a most unusual tree. I had traveled throughout the US and the World, and walked many trails in Fairfax County, but never have I seen this type of tree. It’s commonly called an Osage Orange tree, but also goes by many other names, including its scientific name Maclura pomifera. As I approached it, I saw grapefruit sized yellow fruits on the ground beneath it, with a pile of them arrange in a happy face configuration, as if beckoning me toward them. I looked at those fruits in greater detail, and I thought to myself that the exotic fruit looked like brains, because of the convoluted nature of it.

The bark of the tree has scaly ridges with irregular furrows.

I asked a passer-by if he knew what kind of tree it was. He told me it was a “Monkey Tree,” so that became the basis of my internet search. Indeed, the fruits are also known as “Monkey balls” and “Monkey brains.” The Osage Orange tree is originally native to parts of Texas and Oklahoma. Today the tree has spread to much of the United States and Canada. Male and female trees have different flowers. Only the female tree bears fruit, but it is not edible. The early settlers of America had many uses for this tree and a lot of information on the tree and it uses can be found on the internet. The bark pattern on the tree has a characteristic deeply furrowed, scaly nature. Its twigs have thorns.

Fort Ward is a pleasant place to have a walk, with many ADA amenities. It also has a small museum on its grounds.

The location of the Osage Orange tree is just beyond the historic gate. Notice the Corp of Engineer’s insignia logo (castle) on top of the gate.

One of the things most loved about birds is their wild array of plumage colors and patterns. Where does all that color come from? In this presentation, you’ll learn how pigments and microscopic structures in feathers create the kaleidoscope of beauty we find in the avian world. Topics covered include iridescence, molting and feather wear, the evolution of feather color, and the functions of feather colors.  Audubon Society of Northern Virginia presents.

Ivan Phillipsen is a professional naturalist guide with a background in scientific research. Amphibians and reptiles were his first obsession as a kid. He eventually earned a PhD in Zoology, working in the field of conservation genetics. Ivan’s love of nature has expanded to include plants, fungi, and all animals, including birds. Birds have become his greatest passion. He’s an avid birder, hosts The Science of Birds podcast, and co-owns a birding ecotour company.
