Background information and definitions
A greentree reservoir is a temporary impoundment of a forested river-bottom aimed at providing wildfowl habitat.
Supporting evidence from individual studies
In eastern Arkansas, USA, a site comparison study found significant differences in relative abundances of 12 of 28 non-gamebird species between a greentree site and an adjacent control area (Christman 1984). Singing birds were surveyed in the 1980-1981 breeding seasons. Greentree reservoir management reduced understory vegetation and bird species that are primarily understory foragers were absent or at lower frequencies, and nesting opportunities for ground- or understorey- nesting species were reduced, compared to the control. Canopy-foraging species were not affected. There were overall fewer breeding species and bird abundance was lower at the greentree reservoir site.Study and other actions tested
