Start Where You Are

“Start where you are. Use what you have. Do what you can.” A tenet of volunteering coined by Arthur Ashe. The FMN recipients of the 2022 Elly Doyle Outstanding Volunteer awards most certainly personify each component of that tenet.

The Elly Doyle Park Service Awards were established in 1988 by Fairfax County Park Authority (FCPA) to recognize Ellamae Doyle’s many years of service and accomplishments as a member and chairman of the Park Authority Board. The County’s park system expanded and thrived during her tenure with the addition of significant open space, construction of new recreational facilities and a commitment to preservation of natural and cultural resources in Fairfax County.

The 2022 Outstanding Volunteer awards category included three FMN members – Kris Lansing, David Gorsline, and Beverly Rivera.

FMN Kristine Lansing – nominated by Riverbend Park:

Kris volunteers as one of the park’s roving naturalists/trail monitors.  In this capacity, she routinely engages with park visitors on the trails to educate them about the park’s natural areas and wildlife and to promote other park opportunities such as hikes, classes, and camps.  She removes debris from the trails, reports fallen trees and other issues to park management so that such problems may be addressed rapidly.  She assists in leading the park’s seasonal bird and wildflower walks and helps train new roving naturalist volunteers. Kris is also a Certified Interpretive Guide.

FMN David Gorsline – nominated by Huntley Meadows Park:
David tackles a unique volunteer role each spring as the Duck Nest Box Coordinator. He trains and supervises a small group of independent volunteers, which meets at Huntley Meadows from February to June to monitor duck-nesting activity in the park.
David’s commitment to the Duck Nest Box program has been a significant contribution to the long-term natural resource management at the park. His efforts ensure institutional knowledge is shared with new volunteers, that nest boxes are well-maintained, and that there is annual data to aid in natural resource management decisions. To read more about the duck nesting box project at Huntley Meadows, in David’s own words, click here.

FMN Beverley Rivera – nominated by Lake Accotink Park:
Beverley worked to transform a large area of the park overrun by invasive plants. For three years she has hosted a public workday almost every Saturday. This year she organized and led 47 public workdays and volunteered 182 hours leading 617 volunteers who themselves contributed 1,407 service hours. Beverley and the volunteer crews have also planted hundreds of native plants to restore natural habitat areas.

Please join our community in congratulating these tireless volunteers for their exemplary service to our county parks. They are model volunteers that prove author Sherry Anderson’s quote – “Volunteers don’t get paid, not because they are worthless but because they are priceless.”

Rainbow Pools of Huntley Meadows Park

I am almost certain that most of the FMN newsletter readers have seen or heard of the phenomenon described in this article, commonly called rainbow pools. However, since I recently had my first opportunity, unplanned as it was, to photograph them at Huntley Meadows Park I thought I would share my good fortune. I was returning to the nature center following an afternoon of trail monitoring when conditions came together and gifted me with a fleeting glimpse of this colorful phenomenon. I say fleeting because several conditions need to be met to see the rainbow effect: A. decomposed organic surface slime, B. still waters, and C. just the right angle of sun light. And they were all in convergence as I unsuspectingly walked by; and alas, the effect dissolved in ten minutes as condition C degraded.

They are called rainbow pools because the surface coating on the pools resemble oily layers of red, blue, pink, yellow, purple, and colors that may not have a name. The coating is iridescent too like an oil slick but it disperses when disturbed unlike an oil slick, so disturbing the slick is a good way to test between the two.

These rainbow pools are not a sign of pollution but are instead a natural occurrence in most wetlands. Given a combination of very still waters, a few days without rain or wind to disturb surface tension, and the correct angle of light, nature may provide you with a truly colorful experience. I have seen photos that show much more vibrant colors then in the ones I took. My personal observation is that the darker the water (more tannin) the higher the reflective value of the surface material. In addition, these pools sit among hardwood trees so less oil is exuded in the decomposition process of leaf litter when compared to pine or cypress forests. The pools in this section of the park tend to be temporal and, therefore, are less stained with leached tannins and oils creating a more pastel pallet.

Most often the sheen forms as a result of decaying vegetation, especially from plant materials that exude natural oils, such as pine cones and needles. Another cause can be anaerobic bacteria breaking down iron in the soil. Once the cells begin to decay, they release a reddish slime material, which floats to the surface. Iron bacteria are of no threat to human health. They are found naturally in soils and water in low numbers and will thrive as more iron becomes available. Yet another example of how wetlands are ecologically important systems due to their high plant productivity and their capacity to recycle nutrients. Bacteria in wetland soils break down organic and inorganic structures.

The rainbow effect is typically seen during cooler months and as the sun approaches the lower degrees of an acute angle such as in the morning or as the sun is setting, providing the appropriate reflective angle. The pools pictured in this article are located in the back still waters off the wooded section of Cedar trail at HMP, not in areas near the creeks or other moving water. These photos were taken on 3 December around 3:30 p.m. as I finished an afternoon of trail monitoring. Other pools can be found in other sections of the park.

So you want to chase a rainbow? Try running down a rainbow pool at Huntley Meadows. But running on the boardwalk is not permitted … those trail monitors will get cha.

Who’s Whooo Program at Huntley Meadows Park

It wasn’t the best weather for an outdoor event. Reports had predicted storms. Though the rain had passed through the area over night it was still blustery and overcast. Even with the sun trying desperately to peek through the clouds, occasionally succeeding, a chill remained in the air. The owls didn’t mind. The barred owl even panted a bit after flapping wildly on the handler’s arm, posturing for its admirers. A testament to how well dense feathers insulate an owl against the offerings of winter.

Huntley Meadows Park (HMP) hosted an owl program presented by ‘Secret Garden Birds and Bees (SGBB)’ on 5 Dec 2020. This organization of wildlife rehabilitators, falconers, beekeepers, and naturalists is dedicated to sharing their love of nature through informative and entertaining educational programs, events and activities. This day at HMP the team of Liz Dennison (VMN Banshee Reeks – Loudon) and Tim Dennison showcased 4 owls (Great Horned, Screech, Barn, and Barred) along with Big Red, a red-tailed hawk. As an organization they offer additional programs on general raptor habitat and identification, falconry, seasonal specific raptor behavior, as well as beekeeping and gardening. You may have had the pleasure of seeing them at events around the tri-sate area including Friend’s of Mason Neck’s Eagle Festival and Owl Moon Program. The birds have each been rehabilitated from injury (i.e. being hit by cars) but residual effects from their injuries (i.e. damaged eye sight, beak deformation) precludes safe release back into the wild. They are cared for on SGBB property in Loudon County along with bees and gardens.

The HMP program was offered through Fairfax County ParkTakes on-line registration system and was fully attended in compliance with current Virginia state limitations. The families in attendance were kept actively engaged and asked many questions about the bird’s behavior, characteristics, and habitat; and were treated to, how should I say, ‘spontaneous natural owl functions’ much to the joy of a couple of nine year old boys in the front row. Father said, “well son you got your wish”! The other function was the regurgitation of an owl pellet, which contained bone fragments from its last meal. Hey – people literally cheer for this bonus material folks!

To complement the spontaneous material the scripted information covered a description of each bird, how it nests, seasonal diets, how loss of habitat affects populations, the harmful impact to raptors that eat rodents that have ingested rodenticides, and preservation tactics such as owl box programs. Learning about how owls contribute to the environment and how they survive throughout the year builds a meaningful understanding of these magnificent birds of prey. The following Baba Dioum quote is on their website, “In the end we will only conserve what we love. We love only what we understand. We understand only what we are taught.” I say – we can never be taught too much! We just need to listen. This program was an excellent fun learning experience for all ages.
