REBIRTH OF A VERNAL POND

 DEC Wildlife Preserve, Calverton, NY

This year the Otis Pike Preserve in Calverton, has made a great come-back from a few years ago when this vernal pond area was completely destroyed by inconsiderate people and their dogs, horse back and quad riders. This is an environmentally sensitive area with signs posted. This is also the breeding grounds of the Endangered Tiger Salamander. The DEC kept this area closed to the public this year and I have noticed greater species numbers in odonates, cicada killers and frogs. 

I have been surveying this area since 2005 and so have a lot of documentation on species and habit. In the past, people coming to this small DEC park brought dogs here to do field trials but were not allowed but did it anyway. The dogs constantly running through the vernal ponds to fetch objects for their owners were trampling the bluets and forktails on the shore, crushed all the emergent vegetation into the water or ground and destroyed all the Cicada Killer burrows by running back and forth over them.

Below are some documentation photos I took in 2010 and a few days ago to submit to the DEC for them to keep on file in case the Hunting Group asks for permission again to hold field trials in this preserve.





I have yet to see the return of the Sweetflag Spreadwing (Lestes forcipatus) since last year. The female of this species uses the emergent vegetation or reeds to lay her eggs. Her specialized ovapositer creates a slit in the reeds and she lays her eggs inside the plant. At the time when I noticed all the emergent vegetation destroyed this was the first species I thought about because I was not sure if it had an alternative egg laying method. 

In addition to all the habitat destruction all the hunters that did field trials here with their dogs fired off a lot of rounds to train the dogs. And in so doing, they left large numbers of the shell casings all over the preserve and in the water and made no effort to clean them up. 


This is what the Spreadwings and other Dragonflies were left with to lay eggs or emerge from the water.
Surprisingly Citrine Forktails (Ischnura hastata) were in greater numbers then I had ever seen before. Usually I am lucky if I saw one but now I saw about thirty.

So far this year I am seeing more of a variety of species and in greater numbers. Maybe because this area, that is usually open to the public after Tiger Salamander breeding season, this year has not been reopened. People were bringing their dogs in the preserve to train on their own after the gates were opened. Rangers were frequently chasing people out of the preserve that had dogs with them. 

I am hoping to see more Lestes this year, especially the Sweetflag Spreadwing (Lestes forcipatus). I am already seeing a greater number of five species of frogs, dragonflies, damselflies, very large numbers of Cicada Killers, birds and even Muskrats, which I had never seen before at this preserve!

Long Island Odonate Site Survey - July 18, 20012

Calverton Ponds, Calverton, New York

Water was low on this day and sky overcaste but there was still much Odonate activity. Along with the following odonates seen there were also the Green Darner (Anax junius) and the Comet Darner (Anax longipes). Azure bluets (Enallagma aspersum) were most abundant with approximate 5o seen. This year I found a blue form female Citrine Forktail (Ischnura hastata) for the first time with several males.

Annual Dragonfly Day for Families and Nature Lovers

On Saturday, July 14, 2012, the North Fork Audubon Society held its Annual Dragonfly Day at Skipper Horten Wentworth Park, next to the visitor's center, in Greenport, NY. 

Adults and children of all ages enjoy this yearly event. Every year there are new faces and old. Some people attending year after year! This event is very popular with young children, teenagers as well as adults. Everyone gets out there to try their hand at catching those fast and elusive dragonflies and in the process learns about this popular and beneficial odonate!

No Dragonflies or Children were harmed during this program. All Dragonflies and Children were released unharmed following the event! :-)

DSA Annual Meeting - May 6, 2012

Found this Little Blue Dragonlet floating in the lake, not moving. Took her out to see if she was alive but was limp and not moving so put her on a leaf on shore. To my surprise when I went back ten minutes later and picked her up she started moving! I guess these little dragonflies are very resilient!
