Using our Kaufman butterfly field guide that we won from our friends at http://10000birds.com/ we were able to tell that all of the small blue butterflies we found dancing up and down the paths at Vosburgh’s Marsh were, Spring Azures. Kaufman calls them widespread and common. They occur in spring and summer in the north east and are often thought to be one of the first signs of spring here. So while Will went off in search of spring warblers I got distracted by the little things along the way.
-Vosburgh’s Marsh, and 4 mile point-
Is a track of land half way between Hudson and Cosxackie NY along the Hudson river. It is owned by a local organization called Scenic Hudson that preserves historical and environmentally relevant land along the Hudson river Vally. http://www.scenichudson.org/parks/fourmilepoint
In a accessible point of view the trails are wide, dirt or grass paths that may not be suited to people with disabilities. But there are parking lots at both ends of the road, and the mile drive goes through many different habits so there is plenty to see whether you’re in the car or out. There is not much traffic on the road and as long as you use the marked lots you wont have to face the dogs ;)
This description was taken from http://library.fws.gov/pubs5/web_link/text/upp_hud.htmt , and while it maybe out of date being that the most recent year i could find in the article was 1996, it has relevance in its documenting what this area was and is to this day.
SIGNIFICANT HABITATS AND HABITAT COMPLEXES
OF THE NEW YORK BIGHT WATERSHED
Upper Hudson River Estuary
Vosburgh Swamp-Middle Ground Flats is a freshwater wetland
complex extending for 6.4 kilometers (4 miles) along the western shore of the
Hudson, upstream from the village of Athens at river kilometer 192 (river mile
119). This 486-hectare (1,200-acre) complex includes mudflats, shallows,
freshwater tidal marsh, freshwater marsh, palustrine hardwood swamp, dredged
material bank islands habitat, and freshwater creek, i.e., a 0.8-kilometer
(0.5-mile) section of Murderers Creek to the first barrier, the Sleepy Hollow
Lake Dam. This area’s habitat values for fish and waterfowl are similar to those
of a number of sites already described. What is unusual is that Middle Ground
Flats contains one of the only known bank swallow (Riparia riparia)
breeding colonies in the area. Several rare plants occur here, including
exemplary occurrences of heart-leaf plantain and southern estuarine
beggar-ticks, as well as kidneyleaf mud-plantain and smooth bur-marigold.
