Habitat diversity in uneven aged northern hardwood stands
U.S. Dept. of Agriculture, Forest Service, Northeastern Research Station, 2000 - Nature - 4 pages
Habitat characteristics were quantified in an empirically balanced uneven-aged northern hardwood stand in central New York. Canopy structure, wildlife trees, downed woody material, low cover, and richness and abundance of understory vegetation were assessed. This study provides quantifiable evidence of the diversity of habitat characteristics associated with a balanced stand structure and uniform spatial arrangement of different sized trees in uneven-aged northern hardwood stands.--Publisher description
