- The Habitat Evaluation Procedures (HEP) were used to evaluate pre- and post-construction habitat conditions of the US Army Corps of Engineers Bonneville project in Oregon and Washington. The project directly impacted 20,749 acres of wildlife habitat. Seven evaluation species were selected with losses and gains expressed in Habitat Units (HU's). One HU is equivalent to 1 acre of prime habitat. The evaluation estimated a gain of 2671 HU's of lesser scaup wintering habitat. Losses of 4300 HU's of great blue heron habitat, 2443 HU's of Canada goose habitat, 2767 HU's of spotted sandpiper habitat, 163 HU's of yellow warbler habitat, 1022 HU's black-capped chickadee habitat, and 1622 HU's of mink habitat occurred as a result of the project. This amounts to a total combined loss of 12,317 HU's. 18 refs., 1 fig., 4 tabs.
