Changes In Land Cover And Breeding Bird Populations With Restoration Of Riparian Habitats In East-Central Iowa, Thomas J. Benson, James J. Dinsmore, William L. Hohman
Changes In Land Cover And Breeding Bird Populations With Restoration Of Riparian Habitats In East-Central Iowa, Thomas J. Benson, James J. Dinsmore, William L. Hohman
Journal of the Iowa Academy of Science: JIAS
Conversion of Midwestern riparian areas for agricultural production has greatly altered their function and suitability for birds and other wildlife. Recently, however, restoration of riparian functions has been a major focus of land management agencies in the Midwest. We used historic land-use data to describe land-cover changes since European settlement and the subsequent effects of habitat restoration efforts on the landscape along a section of the Iowa River in east-central Iowa. We then used bird-density data collected in a subset of the study area in 2001 and 2002 to estimate changes in breeding bird populations of the entire study area …
Revitalization Of Ephemeral Pools As Frog Breeding Habitat In An Illinois Forest Preserve, Denins Nyberg, Irene Lerner
Revitalization Of Ephemeral Pools As Frog Breeding Habitat In An Illinois Forest Preserve, Denins Nyberg, Irene Lerner
Journal of the Iowa Academy of Science: JIAS
Almost all land in the eastern United States that has been acquired to preserve nature was once in agricultural usage, and because of this, alterations of ephemeral pool hydrology are common in forest preserves and parks. These ephemeral pools are an important breeding resource for many amphibian species. We hypothesized that filling drainage ditches and recreating a more natural topography at eroded berms would enhance amphibian populations in the forest preserve. Restoration of the hydrology was begun by volunteers in 1993 and was associated with management to reduce non-native woody vegetation. Three ephemeral pools have had maximum water levels raised …
