Tuesday, August 4, 2026
7:00 PM – 8:00 PM EDT

Online event

Fee: $12.09

Registration required

Overview

Join Ana Ka’ahanui for an event all about how birding helps reduce stress, cultivate mindfulness and deepen our relationship with the natural world.

Birding offers more than the excitement of identifying new species—it can also be a powerful practice for reducing stress, cultivating mindfulness, and deepening our relationship with the natural world. Discover how slowing down and engaging your senses can transform the way you experience birds and their habitats.

Drawing on research about the mental and physical health benefits of birding, as well as practices from forest therapy (“forest bathing”), we’ll explore how birds can help us become more present, attentive, and connected. Learn how mindful birding can foster wonder, resilience, and well-being.

Presenter: Ana Ka’ahanui, Certified Forest Therapy Guide, Virginia Master Naturalist, Founder of Wonder Joy Walks, and Co-Founder of Capital Nature.

Quarries Offer Geologic Explorations

Mining operations are inherent to the disciplines of geology and engineering.  Mines can be open pit (surface), or underground.  They can include minerals, coal, and other valuable products. There are opportunities as an FMN to explore quarries in the vicinity and on vacations.  These can be individual visits if open to the public, or part of excursions hosted by universities, professional organizations or amateur geology/mineral clubs.  The first two locations that I note here are from sites included in a Norther Virginia Community College (NVCC) 1 credit course called Triassic-Jurassic Rifting of North America: Geological Field Studies Trip to the Triassic Lowlands of Northern Virginia, which occurred on June 24, 2017. This course explored the geologic history of Mesozoic Era rift basin across the Manassas, Leesburg, and Haymarket areas.  The trip was specific to the Triassic and Jurassic Periods.

At the east side of Luck Stone Diabase Quarry in Centreville, are the igneous rocks. On the west

Manassas Quarry. This quarry excursion was organized by the Mineralogical Society of the District of Columbia (MSDC).  Shown here is a close-up of a hand-sized rock sample containing stilbite crystals, from the Vulcan Quarry in Manassas.  One might also find stellerite, calcite, prehnite, laumontite, chalcopyrite, and chalcedony in this quarry.

side of the quarry are deposited layered sedimentary rocks.  On the north side, in the past, the igneous rocks rammed into the sedimentary rocks and thermally altered them, forming metamorphic rocks by contact metamorphism. The sedimentary rocks are Balls Bluff siltstone, of about 205 million years of age at the end of Triassic.  The light green color layers are more coarse; while darker, purple, red, and lavender hues are finer. The igneous rock originated in a magma chamber from early rifting.  They are an intrusive Jurassic diabase. The red upper color layer is iron rich. This upper most part was oxidized to the air due to its longest exposure time.  The diabase is a dark pyroxene, iron augite.  The light color is a plagioclase feldspar, of a high temperature igneous rock close to the Earth’s mantle. As a magma chamber cooled, there is a magmatic differentiation where the magnesium and calcium minerals settled first.  As the crystals settled they evolved more light in color, and are less mafic. Later the residual melt was more felsic as it flowed through dykes.

About 205 million years ago the mantle bowed up the Earth’s crust.  Rift lakes were created in the Triassic lowlands. They were filled with sediments.  However, the rift basin didn’t open completely, leading to a graben central valley, and the horst mountain area.  The slow cooling of the magma chamber created large crystals.  The NVCC field excursion also discussed many other minerals and structures and how they were formed.  The vegetation on rocks in the quarry are indicative of the minerals present, i.e., calcium loving plants.

At the abandoned Haymarket Quarry, Antioch Road (Silver Lake Regional Park), we observed extruded surface lava.  The rock type encountered here is gray Lower Jurassic Mt. Zion Church Basalt with an inter-bedded Turkey Run Formation. In the Jurassic time some diabase broke out into iron and magnesium flood basalts, sourced from the upper mantle mafic. A vast outpouring occurred into this old river valley.  This flood basalt had little silica in it, so it flowed easily (in contrast to having silica to make it resistant to flow).  Gas bubbles of water/sulfur gas escaped out from a porous/ pitted vesicular texture.  Sediment filled into the cracks and old basalt flow bubbles.  The basalt is porous, the sediment red. This Mid-Atlantic rift event petered out.  After 200 million years of weathering the tough basalt (which filled the valley) formed a topographic inversion, where the surrounding softer rock weathered away.

Pollinator Pathways Turn One in Northern Virginia

/in , /by

Article by Eileen Ellsworth

One year ago, Plant NOVA Natives launched a Pollinator Pathway initiative. The original program was created by a group of highly credentialed environmentalists and conservationists in Wilton, Connecticut and expanded by PNN into Northern Virginia. Its goal is to address habitat fragmentation caused by human activity that has drastically reduced insect populations and degraded the environment. The program suggests ways a community, working together, could create “stepping stones” of native plants to connect these isolated fragments and build a feeding/sheltering/hosting corridor that insects can find and follow.

As a result of the Pollinator Pathway launch, several neighborhoods across the region took steps to build one. Many more native plants ended up in the ground, all of them strategically placed to help local pollinators find sources of food and shelter they so desperately need. Here are some highlights from the past year that may motivate action going forward.
You may recall that the program has two requirements for membership. First, have an existing native tree or a native plant pollinator garden on your property. Second, avoid the use of all broadcast pesticides, including mosquito fogging, which kills every native insect it touches – except the mosquitos’ own larvae! Those happily grow and hatch away in standing water, unfazed by the chemical.
With these requirements in mind, several people in Fairfax and Arlington set out to start pathways, using the Pollinator Pathway signs to help attract interest. There have been many reports of curious neighbors and passers-by who stopped to inquire about the initiative. While the signs certainly helped educate, the program also fostered a deeper sense of community and a growing energy around the program’s goal.
For example, Margaret Fisher created a Pollinator Pathway in Clifton. She says, “It couldn’t have been easier. I had already gone door-to-door ten years ago or so to sign neighbors up for a ‘Bee Safe Neighborhood,’ where people pledged not to use neonicotinoid insecticides outdoors. We celebrated our neighborhood with a very fun block party. I have email addresses for some of those folks and was able to easily convince them to sign up for the Pollinator Pathway. The properties lead more or less contiguously to Chapel Road Park. Very few people in our area use mosquito spraying services, and I hope seeing the signs along the road may prompt them to cancel those services.”
Melania Flores took advantage of an existing effort to plant more canopy trees in her Ashton Heights neighborhood. She reached out to that group, giving her access to a wider neighborhood audience. She knocked on doors, created and printed flyers, and presented the topic at one of the monthly Ashton Heights Civic Association (AHCA) meetings. She also started writing a monthly article for her neighborhood newsletter to further engage and educate. All told, her efforts have garnered 24 Pollinator Pathway participants to date, and that number is growing. All of them have signs that broadcast the program. Melania has been invited to neighbors’ homes and the local church to consult on how they can help. She even offered some of her own native plants as a benefit of joining. And lastly, the entire neighboring community organized a “buckets of doom” initiative with mosquito dunks to help control mosquitos in an effective, environmentally friendly manner.

Sara Holtz recruited 95 properties to the effort, including parks in the Town of Vienna and Fairfax City. She tapped several friends and neighbors in the Miller Heights neighborhood of Oakton and conducted tabling efforts at events hosted by the Vienna Farmer’s Market, the Virginia Department of Forestry, and the Greater Oakton Community Association. She contacted Supervisor Dalia Palchik, Delegate Holly Seibold, and School Board member Melanie Meren to put signs in their gardens. Some local elected officials also promoted the endeavor in their newsletters at her request. The owner of The Virginian Restaurant agreed to put a sign in his garden next to the restaurant. She posted on the Native Vienna Facebook group reaching all homeowners who follow it. Many hundreds of local property owners were engaged and educated through her efforts.

Constance Chubb and Melinda Soltys both rallied their neighbors and friends, grew the program’s membership, and gave away many plants and signs. As for me, I also created a street-based initiative, recruiting eight friends and neighbors to join and display signs. In addition to planting more natives on our own properties, we coordinated on non-native invasive removal efforts in the community-owned park – a collection of wooded parcels that weave between our homes and throughout the neighborhood. Finally, we built a new, very visible pollinator garden on a street-side plot of mowed Japanese stilt grass. Figured we couldn’t go wrong with that one.
Turns out the effort can be as small or as large as you personally choose to make it. The goal is not a perfect carpet of native plants that stretches down the entire length of the street (though that would be amazing). Rather, it’s closing the gap between existing native plantings, which is certainly doable. Even the smallest effort of planting one new native helps. Arranging several new natives in a grouping is a substantial benefit. Either way, the Pollinator Pathway program has inspired important conversations and goal-oriented action, delivering on its promise to better feed and shelter our struggling pollinators and improve the biodiversity of the entire region.
