Loudoun Wildlife Conservancy

Loudoun Wildlife Conservancy offers many opportunities for citizens to participate in nature programs that promote the collection of important environmental data across the county.

Stream Monitoring

Interested in what you might find in a stream near you?  Loudoun Wildlife Conservancy works alongside the Loudoun Watershed Watch in monitoring our local streams for all types of bacterial and invertebrate life. Sign up on our Stream Monitoring page to join a stream team in the search and identification of species integral to monitoring the quality of Loudoun’s streams. Requires a commitment of 3-4 hours at each of three monitoring sessions between the months of April and November.

Bluebird Nestbox Monitoring

Bluebirds, some of our most beloved songbirds for their beautiful colors and cheerful songs, need our help to thrive.  Join LWC’s Nestbox Monitoring program and observe the nesting behavior of this magnificent species, while at the same time providing valuable census information on the local population of bluebirds. We have trails across the county – from Leesburg to Ashburn and Sterling to Neersville, Purcellville and Waterford. Requires about 2 hours per month from April through August on a public trail or you can register your home nestboxes with us and report your data. Visit our Bluebird Nestbox Monitoring page to become a part of this rewarding experience.

Amphibian Monitoring

Amphibians are wonderful natural indicators of the health of wetlands and forests. In order to gauge just how well these fascinating creatures thrive in Loudoun County, Loudoun Wildlife Conservancy launched the Loudoun Amphibian Monitoring Program (LAMP). Help monitor the health of our amphibious population through frog and toad call surveys, amphibian site surveys, and migration mapping. Time commitment can be as little as a few hours in each of the four monitoring windows from February through July or more if you really get into it. To volunteer for any of these subsets of LAMP, or for more information, visit our Amphibian Monitoring page.

Bird Atlas

Participate in Loudoun County’s unique bird atlas program, in which volunteers track and record the species and numbers of birds found in Loudoun. The county is divided into 75 blocks, and each of these 10 square-mile blocks is assigned to a different individual or group to ensure countywide coverage. The atlas has been an ongoing project since 2009, and is set for publication in 2014. Volunteer while you can – more eyes on the ground mean better data for the atlas!  You can sign up as a helper for a block or a block owner, or just sign up to report incidental sightings. All birds count so this is a great activity for people of all experience levels. Time commitment can be as much as you like.  For more information, please visit our Bird Atlas page.

In further celebration of National Frog Month, I thought it’d be good to share this film with you.

Frogs: The Thin Green Line takes us from the global perspective of frogs and their populations around the world right down to our local level. Frogs have been around for over 250 million years, evolving in some of the most amazing ways, in such great diversity of colors and specialties. Yet today, they are at the center of one of the greatest mass extinctions since the dinosaurs and this story is playing out right in our own backyards.

Learn about what’s happening globally and then discuss what we can do locally to not only monitor these trends through our amphibian monitoring program but also take action to protect and restore habitats.

We did a showing of this movie at one of our programs last fall and may do that again in  the future but in the meantime, it’s definitely worth checking out. You can watch the full program online at the PBS Nature website.

As you may recall from my post last year, April is National Frog Month!  While we may laugh at how there seems to be a month or day for every cause, I get excited about a few of them and Frog Month certainly is one of those.

Of course, our season for big amphibian activity really starts up in March and goes through at least July but we’ll take April as a good time to focus in on frogs.

Here are a few ideas for things to do in celebration and appreciation of our frogs (and other amphibians) this month:

- Clean up litter around a wetland – For some reason, it’s been pushed into our psyches that streams, ponds and other waterways are a good place to dump trash. You see old refrigerators, tires, litter and all sorts of other things getting dumped in these sensitive areas. Cleaning up one of these place not only helps get rid of the pollution but also helps change that psyche. A place that has trash is more likely to get more of it. Cleaning up a location shows that someone cares about it.

- Build a frog pond – We have a great set of articles on building a backyard pond. Backyard ponds don’t have to be very large to attract visitors either so this can be lots of fun in all sorts of places.  Just don’t be tempted to buy tadpoles….be patient and your local neighborhood frogs and toads will find it.  And no fish please.

- Learn the frog calls and try your hand at identifying them – Frogs call primarily in the spring to both establish territories and attract mates so this is a great time of year to learn their calls. Through our amphibian monitoring program, volunteers receive an id guide as well as a cd so if you really get interested in frogs (and toads and salamanders) consider signing up but in the meantime, you can find calls on the Virginia Herpetological Society’s website.

- Join us for Frog Walk – while our April walk is already full, we’ll be doing more walks through the late spring and summer. Check our calendar for details.

- Learn about the Frogs and Toads of Loudoun – We had an article in the Habitat Herald awhile back specifically on the species of Frogs, Toads and Salamanders that we have here in Loudoun.  You can read through that article and then have some fun with our Frogs and Toads crossword puzzle.

When ere wee froggie wakes,

This past Sunday we had our first amphibian foray of the year and headed over to Algonkian Park to explore the amazing network of seasonal waters and swampland that is over there.

The good news about all that snow that we had this year is that the swamp area and the vernal pools that run through Algonkian were full! We compared photos from last year at some of the same points along the trail and the comparison was dramatic. A vernal pool last year that was no bigger than a bathtub spanned over 100′ this year. It was great to see the water levels back up and the ground properly saturated.

Along our walk, Mike Hayslett, our field trip leader and director of The Virginia Vernal Pools Program, talked about soils, seasonal wetland habitats, lifecycles of the amphibian life found in these habitats, and other cool nature facts.

We did a bit of netting to try to find evidence of Marbled Salamanders as well.  Marbled salamanders lay their eggs in the fall in the dry leaf litter. The female then waits and protects the eggs until the fall rain comes and fills the pools. The eggs then hatch and develop through the winter. At one of the pools we did find a Marbled salamander tadpole. It was not alive but we could still make out the markings to identify it. Salamander tadpoles are easier to find at night because they are nighttime predators….moving through the water column in search of tasty insects.

Other critters that showed up in our netting were various freshwater insects – isopods, coepods – as well as clams. It was really fun to explore these swampy waters and learn about the lifecycles of the animals that use them. 

As soon as we have our first “Big Night” rainfall of the spring, the swamp will be crazy with activity from Wood Frogs, peepers, and other salamanders. Looking forward to that rain, hopefully this week!

I posted a few photos from our walk on our Facebook page – feel free to check them out.

For those interested in Amphibians this will be an exciting week!  I was just checking the weather and there’s a chance of rain Wednesday through Friday and the temps are supposed to be around 50 degrees!!  PERFECT!!

We still have room in our Amphibians Afoot Class and Field Trip so if anyone is interested please sign up soon. If it rains those nights we’ll definitely be doing a night excursion and perhaps a road crossing assist.

So what’s the big deal about the first spring rains in March? Man, if the typed word could only show my excitement! I’m about to jump out of my seat on this and can barely catch all my typos!

The first warm rain in March is when Wood Frogs, Spring Peepers, toads, Jefferson Salamanders and others make their move! Imagine them in their forest homes, under logs, in burrows, nestled in the cushion of fallen leaves….the winter slumber is over and it’s time to breed!  They can’t leave their havens without some rain because their skin will dry out and they can’t move during a daytime rain because predators are out. So they wait……then it happens! Nighttime falls, the rains come and they migrate in force! 

They’ll migrate from as far away as 1/4 mile to get to the vernal pools and other wetlands where they were born in order to meet up with their fellow species to mate, stay a few days and then return to the forest. Wow – it gives me goosebumps just thinking about it! Here’s an interview I did with Mike Hayslett when he was here with us last year: Spring Wetlands Interview

This special spring rain sets the season off and is also why we get our amphibian monitoring program going this time of year.  We have these big events and the amphibians are most visible from March through about June/July. Oh it is just so much fun!

So, watch the weather and if you’re out at night when it’s raining, watch the road – what you may think are leaves blowing across the road may actually be frogs, toads and salamanders trying to cross!  Let us know what you encounter!

And please do check out the Amphibians Afoot Class mentioned above – there’s a small fee for this one to help cover some of our costs but it’s well worth it!

Seven of us went out to Bles Park in Ashburn, Virginia on Saturday night for a fun night hike to look and listen for frogs.  This is just the second of such night hikes that we’ve done so far but they’re so much fun that we’ll definitely be doing more starting next spring when the frogs and toads are really out in force.

For our walk last Saturday, we started by gathering in the parking area, discussing the possible species that we would encounter and listening to recordings of their calls. Through past nature walks at Bles, we’ve identified at least six species of frogs and toads that are definitely at Bles, but due to the time of year, we were most likely to only hear three of them (Green Frog, Gray Tree Frog and Bullfrog).

So, off we went along the trail. Bill Roberson from the county’s Parks and Recreation dept came out as a resource for us in case of anything which was great since it allowed us to just focus on wildlife. The park certainly looks different at night but donned with headlamps and flashlights, we were able to spot all sorts of great creatures.

As we walked along, we encountered numerous (at least 20)  juvenile American Toads (toadlets) out hunting for dinner -  hopping across our path and hunting through the grasses. There were also quite a few millipedes out hunting along with some really interesting beetles.

We were hoping for a slight drizzle to get the frogs to call but it missed us and the frogs stayed pretty quiet except for a lone Green Frog that called from along the river. As we explored along the river, we saw a bat or two hunting over the water. By the size of it, I’m guessing a Big Brown Bat.  We’ll have to bring the bat detector next time. We also had Great Blue Herons flying over just as the sun was setting.

The big fun of the evening was spotting the many Pickerel Frogs along the river.  They would have been breeding in the early spring time so it’s no surprise that they were not calling out their funny snore but it was great to spot them and practice some night photography.

We wrapped up our hike at 9pm.

So we held our first evening amphibian foray into the woods last night.  The plan was to enjoy the Gray Tree Frog chorus at the Blue Ridge Center, since in past years, the chorus was in full swing this time of year. The Gray Tree Frogs, however, must have missed the note because they stayed quiet all evening.

That was ok though, since lots and lots of American Toads and Green Frogs, as well as one Bullfrog, were out and about.

We started the evening with a short talk about amphibians and Gray Tree Frogs in particular, looked at photos of the frogs (including the egg and tadpole stages as well as frog scat!) and listened to a recording of the Gray Tree Frogs calling so we all knew what to listen for. 

We had 18 people on the walk with us, three of whom were burgeoning (6-8 year old) herpetologists. As we headed out along the trail, it didn’t take long to find our first American Toad crossing the path.  The three young boys hopped into action and caught it so we all could see.

We stayed at the pond near the visitors center for a bit as we listened to the Green Frogs calling and swimming through the green duckweed. We then headed down to Piney Run stream to see if we could hear some other species….like our elusive Gray Tree Frogs. Along the walk, we must have encountered at least 15 more American Toads – of all shapes and sizes. We had just had a light rain and it was humid so they were no doubt out hunting for their dinners.

Along Piney Run, we listened for a bit, observed some bats feeding just over the tree tops, and scanned the trees for any eyes watching us. After a pause here, we headed back to the pond. By this time, it was dark and the Green Frogs, with their banjo twang, were in full song. We used our headlamps and flashlights to scan the pond and saw lots of eyes reflecting back. It was great to see so many of them.

We wrapped up a little past 9pm and headed back to the visitor center where we found another toad hunting around the house. It was fun doing a nightime nature walk and we look forward to doing it again. Keep an eye on the Loudoun Wildlife Conservancy Programs Calendar for more events like this.

Ten people, including a couple celebrating their 27th wedding anniversary, participated in the Loudoun Wildlife Conservancy’s free monthly bird walk, led by Joe Coleman & Larry Meade, at the Blue Ridge Center this morning and found 56 species in the fields and woods there. 

After listening to a couple of Grasshopper Sparrows and the first of many (maybe 30) Indigo Buntings we carpooled to the southern edge of the center at the end of Sawmill Rd.  From there we walked along the western edge of the field where we heard and saw a variety of birds including a couple of White-eyed Vireos but missed on the Blue-winged Warblers and Chats that nest in that area. 

We then followed Butterfly Alley to Sweet Run & into the dense forest along the stream to the Arnold Rd Trail.  Within 200 yds of entering the woods we started hearing numerous Acadian Flycatchers (about one every 100 yards or so) and a few Wood Thrushes, but not a single Kentucky Warbler or Ovenbird, both of which were common in this area just a few weeks ago.  However, we did start hearing and then finally got great looks at several Scarlet Tanagers, a few of which were beginning to molt.

We took a side trip to Gordon Pond where we heard and saw a number of the same forest species as before and added a few more including several Blue-gray Gnatcatchers.  After visiting the Gordon Pond we returned to the Little Turtle Trail where a few of us heard a Worm-eating Warbler. 

After crossing Piney Run we took the Farmstead Loop back to the Visitor Center, arriving there about 12:15.  There was a flurry of activity around the small pond near the Visitor Center, including a very cooperative Louisiana Waterthrush which posed for photos.  We added a couple more species, including a Raven, while tallying on the porch. 
 
When we drove back to Sawmill Rd to pick up our cars about 12:30 there was a Blue-winged Warbler in the hedgerow next to the parking area.
 
In addition to a lot of different butterflies, we also saw two large Black Snakes, one high in the trees where there was a lot of bird activity and one high on the side of one of the old stone houses on the center. There were also American Toads all along the trail and numerous green frogs at the pond. It was a great day for exploring Loudoun nature!

Al Eddy caught some great nature and wildlife photos during the walk and a few are included here in this post.

For those of you involved in our amphibian monitoring program and those just curious, I just learned of this really interesting article about a study done that shows that frogs, toads and newts tend to mate under a full moon.  When we talk about Big Night events, we’re generally looking for those rainy nights since that’s when amphibians can move through the forests most easily and without dehydrating. This article gives us another interesting factor to consider.
