AOA News and Conservation Victories
Core Portions of Bison Hollow Preserve listed as an Ohio State Nature Preserve. The ODNR Division of Natural Areas and Preserves held a signing ceremony with Director Mertz and AOA representatives present for the recently announced designation of Bison Hollow Preserve as a State Nature Preserve.
Bision Hollow is one of the jewels of the distinctive Hocking Hills landscapes. It is covered in deep, older growth hardwood forests with large stands of hemlock that provide habitat for many native species that are classified as rare, threatened or endangered.
The overall Bison Hollow Preserve now consists of 1,100 acres which includes high sandstone bluffs, gorges, rock shelters and caves, waterfalls and relatively rare high quality coldwater habitat streams in both Hocking and Vinton County of southeast Ohio.
A draft calendar of events for 2025 is presented below and shown at the following link:
