During July and August 2000 and 2001, mist nets were set concentrated on three drainages in the Jessieville District of the Ouachita National Forest: North Fork Ouachita River (ten sites), Irons Fork Creek (five sites), and Muddy Creek (two sites). A total of 83 bats representing seven species was caught during 20 evenings (43 net nights). Sampled habitats included pools in road ruts, intermittent streams, man-made ponds on ridgelines, a wet road rut fed by a seep, small drainages that flowed only after a heavy rain, a standing pool in a clearing, and larger streams. Eastern red bats (Lasiurus borealis) were caught 64 times. Other bats caught included three evening bats (Nycticeius humeralis), eight eastern pipistrelles (Pipistrellus subflavus), two hoary bats (Lasiurus cinereus), three northern long-eared myotis (Myotis septentrionalis), one big brown bat (Eptesicus fuscus), and two Seminole bats (Lasiurus seminolus). A juvenile Seminole bat, only recently volant, represents the first documentation of likely reproduction of this bat in Arkansas.
