A total of 33 species in 14 genera were collected and identified the myrmecines Aphaenogaster rudis and Myrmica punctiventris, and the formicine Formica neogagates were the most common and abundant species encountered. We also determined the efficacy in a northern temperate forest of five different collecting methods - pitfall traps, litter samples, tuna-fish and cookie baits, and hand collection - routinely used to sample ants in tropical systems. Prior to the experimental removal of red oak trees to simulate effects of sudden oak death and examine the long-term impact of oak loss at the Black Rock Forest (Cornwall, New York), we carried out a rapid assessment of the ant assemblage in the 10-hectare experimental area. Pests and pathogens are causing widespread loss of dominant canopy tree species ant species composition and abundance may be very sensitive to such losses.

We arrived at the parking area at approximately 9:15 am and there were only several cars in the lot. It was a beautiful August day with temps in the low 80’s, sunny and slightly humid. One man and his dog at Black Rock summit, a woman walking her dog on a nearby trail and a couple walking in the opposite direction as we approached the parking area at the conclusion of our hike. We spent a good portion of the day there and only ran into a few people. I hiked the area a few years ago and decided to pay a return visit. There is a network of old logging and mining roads, and together with cut footpaths, provide over 30 miles of trails in Black Rock Forest. Trailhead parking: Black Rock Forest Main Parking Lot – Reservoir Rd, Cornwall, NY 12518īlack Rock Forest is located in the western Hudson Highlands region in Orange County, NY, mostly in the town of Cornwall, with the southern fringe overlapping into the neighboring town of Highlands. At 3,870-acres, it is the largest area in the Highlands with a sustained elevation over 1,200 feet, providing the hiker with sweeping vistas and strongly contrasting habitats.
