Biological Surveys
Being a relatively new refuge, we are still in the process of establishing the full compliment of baseline biological surveys. We have conducted habitat mapping using geographic information systems, breeding bird surveys, marsh bird surveys, aerial waterfowl surveys during migration and winter, small mammal surveys, insect trapping, anuran (frogs) call counts, and vernal pool investigations.
The refuge enrolled seven fields totaling 230 acres in a regional research study looking at different management techniques to benefit grassland-nesting birds. We have studied three different techniques for taking a census of wintering grassland songbirds.
