In the 1850s Iowa’s land cover was composed of about 80% grassland. Due to the increase in agriculture, Iowa’s grasslands have declined to about 20% and Iowa’s land cover is now composed of about 63% corn and soybean fields. This habitat loss has contributed to the degradation and fragmentation of remaining Iowa grasslands that many animals rely on. The impact of this large scale habitat change has not been well studied for snakes, amphibians, and small mammals. We're seeking to fill this gap.
Grassland birds, such as dickcissels, meadowlarks, and upland sandpipers, have declined by almost 40% over North America between the late 1960s and today 1968–2011. This decline is being driven by loss or degradation of grassland habitat continent-wide, including replacement of grassland with agricultural land, fragmentation of remaining grasslands, degradation of rangelands in the western US, and re-forestation in the eastern US. Stopping and eventually reversing the loss of grassland habitat will be necessary to halt the decline of North American grassland birds. To learn more about an innovative approach to restore grassland habitat to protect at least some species of grassland birds read on.
