It consists of about 8000 acres of federal and private lands that are managed for ecosystem research projects by the National Audubon Society, which has cooperative agreements with the federal land management agencies. This summary of the early history of land settlement of the Research Ranch area and some of the subsequent land transactions is taken primarily from information in the land records of the BLM and ASLD.
