We had a ssssspectacular Saturday as part of a Virginia Herpetological Survey (VHS) team for Mason Neck State Park and National Wildlife Refuge.  Tony & Caroline along with about 20 other VHS members participated in the day long search for reptiles and amphibians.  Each animal found was documented along with the location and  micro-habitat it was found in.

We started the day around 8:30 am.  We were divided into 5 teams that were given 5 different sections of the area to survey.  Our team was assigned to the areas of the Wildlife Refuge that are closed to the public.

We drove to the end of the main Refuge access road to an area that used to be a farm.  Five foot tall grass, poison ivy, and millions of deer ticks awaited us.  We were not deterred!  Almost immediately an eastern box turtle was found.

And then in a very short period of time, we found a brown snake, multiple worm snakes, more box turtles, two spotted salamanders, and giant native millipedes (I know – they don’t really count on a herp survey, but they were so cool!)

We also found two black racers – snakes that are known for being fast.  One of the racers was in a somewhat odd micro-habitat.  It was about 5 feet off the ground hanging on a small tree growing on the edge of a cliff.

We continued herping (searching for reptiles and amphibians) throughout the morning.  It was hard work hiking through the brush, lifting logs and turning over rocks, but we were dedicated to our mission.

We drove a few miles down to an area of vernal pools, marshes, and wetlands.  We found more herps, including cricket frogs and green frogs.  One of the green frogs was also in a somewhat strange spot (for a green frog), he was about 3 feet up on the side of a tree stump.

While in the wetlands, we also found some frog predators.  Many painted turtles were spotted basking on logs.  A large snapping turtle was found in a pond under a log – but he foiled our attempts to take his picture.

Many people believe the myth that venomous cottonmouth (water moccasins) live in the Washington DC area.  They do not.  Our area is too far north for them to survive.  We do, however, have harmless northern water snakes which are often confused with both cottonmouths and copperheads.  Like many snakes, northern water snakes will flatten their bodies and heads to appear more “viper like” when they are threatened which can lead to their mis-identification as a venomous species.

In the same wetland location, we also found beautiful ribbon snakes.  Ribbon snakes are similar in appearance to their close relatives the garter snakes, but the ribbons are much more slender.

Whew – after all this success we started to get a bit hungry.  So we decided to head back to the meeting site,  eat lunch, and find out how the other teams were doing.

Hungry, Hungry Herpers!

After our short lunch break, we headed back out into the field for more searching.  We discovered more worm snakes, more box turtles, lots more green frogs, more spotted salamanders and we had an encounter with a rarely seen in Fairfax County lizard species, the ground skink.

Deep in the woods, far from any roads or trails, we also discovered a sign of the past.

Dial S for Snake

No copperhead snakes were found during the entire survey.  Over 40 dedicated reptile specialists searching a large area of protected forest and no copperheads.  This is actually normal.  Copperheads are not nearly as common as some people believe.  Copperheads are also shy and afraid of humans.  They will only bite if they feel threatened.  So, you know, leave snakes alone.

We did, however, find a venomous species of arachnid hiding under a log:

Around 5 pm, we headed back to meet up with the other teams and share our data collection for the day. The VHS president Kory Steele was there adding up all the numbers from each team. Soon, we would learn which team found the most animals.
Guess which team won? Well, as Kory reminded me, this was not a contest. Our mission was to collect data to assist with the conservation of reptiles and amphibians. (Ok, but our team won – we found 57 individual herps representing 17 species – woo hoo woo hoo!)
All of the animals we found that day were left in the spot we found them. Well, except for two animals – alien invaders were found in a turtle sampling trap.

The aliens were the Frankenfish – the Northern Snake-head! Apparently, there is now a large breeding population of these introduced exotic fish in the Potomac River and its tributaries in the Mason Neck/Pohick Bay area. This new invader could cause unknown consequences on our native fish, reptiles, amphibians, insects and possibly even birds and mammals. Surveys such as the one the VHS teams completed at Mason Neck are crucial for the protection and conservation of our wildlife.
We had a sssssssuper ssssssssuccessful Ssssssssssaturday. It was snaketacular.

Fort Belvoir, located in southeastern Fairfax County, VA is home to some of my favorite hiking trails through some amazing habitat. This hike took place with Caroline on April 8, 2010. Let’s see what we can find!

Last weekend we had some beautiful early April weather here in Northern Virginia.  After our brutal winter – we deserved it!  We headed out to Hemlock Overlook Regional Park to look for some signs of herpetological spring.  And we found it!

Our first find was one of the most common vertebrate creatures in the eastern United States:  the red-backed salamander.

Red Backed Salamanders

Red backed salamanders come in three different colors:  red backed, yellow backed and black or “lead” backed.

Red backed salamanders are different from many other amphibians.  They are members of the lungless group of salamanders – so they get all their oxygen absorbed into their blood stream through their slimy skin.  They also lay their eggs on land and the the larvae go through metamorphosis in the egg.  So, red backed salamanders never have to leave the land to lay eggs in the water the way most amphibians do.

Toads, on the other hand, must return to the water each year to mate and lay eggs.  At Hemlock, the woods were alive with the pleasant music of male toads singing to attract females.

American Toad

The male will “hug” the female (the science word for this toad hug is amplexus), and the female will lay hundreds of eggs encased in gelatinous goo into the water.

In a few weeks, the temporary pools in our area will be filled with millions of black tadpoles that will quickly grow tiny legs and metamorphose into tiny toadlets.  To attract insect and slug eating toads into your garden, consider adding a toad home

We did not find any snakes on our trip at Hemlock, but the next day, one of Caroline’s neighbors called her to come and get a visitor out of her bathroom.

Yep, I would definitely say that herpetological spring has sprung!

After the snowiest winter in Washington’s recorded history, the amphibians have finally made their way to the vernal pools to signal the beginning of spring. They are bit later than usual in this area. Late February is typically when spring peepers, wood frogs, and spotted salamanders make their first appearance in the DC area. This year, due to abnormally harsh winter conditions, they were about two weeks or so behind.

Last Friday night a few of the team members from Reptiles Alive had the special opportunity to visit a wetland area that is usually off-limits to the public. Off limits because it is behind a shooting range! We were invited by master naturalist Greg Zell along with a handful of other professional herpetologists and naturalists.

We met up at dark in the cool rain. Perfect weather. Well, maybe not perfect for humans, but definitely perfect for amphibians! On the road into the park, we discovered our first amphibians of the night – American toads!

After putting on our rain gear, we crossed the shooting range walking over millions of broken clay targets until we reached the wetlands.  Immediately someone yelled “Spotted!”  Then more shouts were heard, and we realized, we were in the middle of hundreds, possibly thousands of spotted salamanders!  It was AWESOME!  They were everywhere!  Large female salamanders were being surrounded by 5 to 10 males at a time.  Salamanders were almost everywhere you pointed your flashlight, crawling through the mud or swimming like fish in the cold, clear water.  After an hour or so, spermatophores from the males began to fill the water as the ancient amphibian breeding rituals took place. It was the most amazing salamander sight I have ever witnessed.

We spent a few hours observing them, photographing them and discussing them before we all decided it was time to come in out of the rain and dry off.  A few of us headed to Dogfish Head to warm up and have a late night dinner, but that, is another story…

I had heard stories of the black flies that live in the north, but I never believed that they could be that bad.  I was wrong.  I am trying unsuccessfully not to scratch as I write this.

Last week I went with my Dad and Kay to Mont Tremblant, a mountain resort area in Quebec, Canada.  It was a fantastic place, full of gorgeous rivers, lakes, and mountains.  We went fishing for trout, hiked on great trails, and ate LOTS of fantastic French food.

The area is full of lakes carved by glaciers that retreated long ago.  The lakes are full of frogs and fish.  I saw green frogs and heard their calls, along with the calls of gray tree frogs, bull frogs, and spring peepers.  I did not see any reptiles, but I was lucky to catch a speckled trout on our fishing expedition.  During our time on the boat, there were no insects to be seen (or felt).

I was on the dock of a very nice restaraunt, petting a cat, when I had my first real taste of what black flies are capable of.  They were swarming all around my face and head.  I brushed them away and figured they were kind of like gnats – annoying, but basically harmless.

I went back inside the restaraunt to place my order for dinner (grilled venison, yum!), and noticed I was bleeding around my chest and neck.  The waitress who spoke mostly French, noticed, and began to explain what black flies can do to a person.  She said they liked to crawl under your clothes and hair where they bite throught your skin ans suck blood.  Their bites will cause bleeding, then later, the bites swell and become very itchy and in some people, very painful.

I excused myself from the dinner table, went to the restroom and shook all my clothes out.  I then noticed that I was bleeding from many, many bites on my face, neck, and back.  It was a bit gross.  After the bleeding stopped, I went back to the table and enjoyed a dinner that was magnifique.

A day later, all of the bites had turned into large red welts that itched like mad! I knew I had to avoid getting any more black fly bites.  I now had respect for them.  These were no gnats!

It turns out, black flies breed in clean, fast running creeks and rivers.  The larvae cannot tolerate pollution or still water.  The larvae and adult flies are a major source of food for trouts, birds, and many other insects and animals.  The adults typically come out around mid-May and stick around until the end of July, but the actual “black fly season” depends on location and weather conditions.

Black flies are a major problem for livestock.  Because black flies like to crawl inside nasal passages, cattle an other livestock are sometimes smothered by the swarming flies.  The flies can also spread disease and cause such stress to animals, that they die.

I had a great time in Canada – and I would love to go back.  But this time, I’ll remember to bring the bug spray!
