2012-2013 ASC Speaker's Schedule
May 17 Tim Bodeen, Malheur National Wildlife Refuge Manager
On August 12, 1908, the U.S. Congress established Malheur National Wildlife Refuge "to preserve the habitat values of [Malheur Lake] for migratory waterfowl, and especially, the colonial nesting species." The Refuge’s lakes and wetlands were world-renowned for their productivity and amazing populations of waterfowl and other birds. Then in the 1920s, the Common Carp was introduced into the local watersheds to control vegetation in irrigation canals. They soon entered the Refuge’s aquatic systems and since then have decimated the Refuge’s aquatic ecosystem productivity. It is estimated that carp’s aquatic degradation has reduced use by waterfowl/birds by several million birds per year as well as undocumented impacts to the endemic fish and mussels. The Refuge to date continues to be unable to fulfill its established purpose because of the carp infestation.
From the 1930s through the 1990s, rotenone treatments were used to control carp in the Refuge’s aquatic systems, which temporarily restored productivity and waterbird/fowl use on a short-term basis (2-4 years), before rebounding to pre-control levels. This non-selective method impacted native fishes (e.g., redband trout, suckers) and mussel populations. A variety of carp control strategies are needed to reduce their populations, which could include collection and passage deterrent structures, commercial harvest, chemical attractants/detractants, passive fishing, and reestablishment of nesting piscivorous colonial waterbirds such as herons, egrets, grebes, ibis, pelicans, terns, and cormorants as well ospreys.
