Hidden Oaks Nature Center (HONC) has an opportunity for animal lovers!
A volunteer or two are needed to help with the care of exhibit animals on Saturdays. Animals in the exhibits include turtles, toads, snakes and other small critters.
The job could be shared by 2 volunteers. They would split up the month, each doing at least 2 Saturdays. Because there is training involved in this volunteer opportunity, HONC is asking for a 6-month commitment.
Record your hours in Better Impact as S182: FCPA Nature Center Animal Care. In the Description field, note that you worked at Hidden Oaks Nature Center.

Preparations for construction take many forms. For Hidden Oaks Nature Center, the upheaval to the trees, park access and program scheduling are but a few of the aspects that site staff have long considered to get ready for the current renovation. One consideration was the construction’s impact on the pond that many frogs and salamanders use to mate in late winter and spring. Assisted by Eagle Scout Daniel Tootle, Hidden Oaks management planned a year in advance to minimize the habitat impact – a plan that has proven to be successful over the past two weeks.
Wood frogs arrived at Hidden Oaks Nature Center’s temporary pools on Feb. 20, 2022.
The current construction required filling in the existing pond. Staff’s concern was that this would disrupt mating patterns for the frogs and later the American toads and yellow spotted salamanders. Every March, more than a hundred wood frogs gather in a small body of water just outside of Nature Playce – the site’s outdoor nature exploration area. The male wood frogs call in a laughing duck manner to woo the female wood frogs from their winter slumber. All meet up in the pond. Females lay thousands of eggs which hatch into tadpoles which metamorphose into froglets by mid-summer.
In June 2021, Dylan Tootle and 23 volunteers installed two temporary ponds on either side of the planned construction zone as part of Dylan’s Eagle Scout project. Using repurposed baby pools and prefabricated pond liners, Tootle’s “ponds” created above-ground and in-ground options for the park’s resident amphibians. The first wood frogs appeared on February 20 and soon had eggs floating in the above-ground pool in front of the building. A few days later, the second pond was brimming with frogs. While programs are currently suspended at Hidden Oaks Nature Center, the frogs and their cacophony of sound have fascinated the construction crews and contractors. Unfortunately, a dozen frogs opted to disobey the signs, hop into the construction zone and plop into the partially rainwater-filled new pond still being built. The team from Kadcon installed a ramp in the new pond to accommodate the wood frogs, who find it easier to jump in than climb out the comparatively steep sides. Though rains have created plenty of puddles over the last few weeks, the frogs seem to prefer our ponds over the rainwater puddles.
Frog mating calls joined the construction noise to create a cacophony of sound at Hidden Oaks.
Wood frog egg masses soon appeared in the baby pool pond.
The new larger and permanent pond should be ready for its new inhabitants next week. Naturalists will then relocate the egg masses and newly hatched tadpoles into their new home. Sometimes the earliest laid eggs do not survive a hard freeze, but the adults can return to their shelter under the forest’s leaves and reenter “brumation”, a partial form of hibernation. They will rouse again when the weather warms up. The staff will track which pools the frogs and salamanders prefer and look forward to sharing the marvels of metamorphosis with visitors old and young.
Hidden Oaks Nature Center is located at 7701 Royce Street in Annandale. Please note the Nature Center is closed Feb. 14 to June 10, 2022, for renovations. No public restrooms will be available until April.

Hidden Oaks Nature Center was recently awarded 3rd place in a county-wide Geographic Information Systems (GIS) competition. GIS refers to electronic maps with information attached to them. The award recognized the story map that site staff and county employees created for the 50th anniversary of the Center. A story map is an online site that tells a story using maps, pictures, and words.
Hidden Oaks actually has two story maps. The first, created for the anniversary, “Imagine the Next 50 Years,” is an evolution of the park, the building exhibits, and the surrounding areas. The second, “Habitats and Havens: Tour the Old Oak Trail” is a walking informational tour of the Old Oak Trail. The web applications are available on the Park Authority website.
“Imagine the next 50 Years” encourages viewers to consider how they can impact Hidden Oaks over the coming 50 years through learning about the last 50. The project served a twofold purpose – both communicating how the Nature Center has served the community at large and promoting the 50th anniversary event. Commercial aerial imagery supports the “Running Out of Room” section, while a photo taken from a helicopter shows the baseball fields after they were constructed. The “Expansion Through the Decades” section contains embedded web maps that users can expand to see how the park has changed from 1976 to 2019. Each section concludes with a reflection on how the next 50 years may evolve, while the app closes with a reminder that everyone can make a positive impact in their community.
“Habitats and Havens” makes a great tool for someone who lives far away or is confined to their home for some reason. For example, for grandparents so they can see and learn about the trail their grandkids walk on and ask them about it.
Both are useful to bring the past to life for young visitors who like Hidden Oaks and are interested in knowing what it used to look like. They also brings awareness to the historical and current importance of the nature center and the green space surrounding it and will hopefully spark interest in conservation and being mindful of the planet.
Story maps, technology advances nature. Do you have a story map in your future?

Some flowers, ferns and grasses persist in winter as dried stalks and provide food for wildlife. Learn about local winter weeds and try drawing some from our collection. Ink pens work especially well with this subject. See a brief demonstration, then try it yourself using our collection of dried plants. A suggested list of supplies will be sent upon registration.
