Blanca Wetlands has been designated an Area of Critical Environmental Concern, or an ACEC. This BLM designation is based on an area’s unique, rare or sensitive resources. Blanca was designated an ACEC specifically for its recreation and wetland values, including playa and marsh habitats containing large populations of water birds, amphibians, macroinvertebrates, and 18 threated, endangered and sensitive species.
The BLM completed an environmental assessment (EA) to analyze the potential impacts of enlarging the Wetlands ACEC. The EA presented several alternatives ranging from changing the current boundary as proposed, to enlarging the current boundary with modifications, or taking no action at all. The proposed boundary enlarged the ACEC from 9,714 acres to 122,762 acres. No new water rights were created and no land ownership jurisdictions changed.
