Significant Findings

Wetlands created in 1975 to replace those lost to interstate highway construction were initially assayed for aquatic invertebrates and birds in 1981 and 1986. Assays in 1994-1995 showed approximately one-third fewer taxa of invertebrates than in 1982-1983 while bird productivity has remained stable in the wetlands.
