Blanca Wetlands

Welcome to Blanca Wetlands!

NEW: Final Environmental Assessment and Finding of No Significant Impact (FONSI) are now available.

Long ago, a network of playa lakes, ponds, marshes and wet meadows shimmered in the desert scrub of the San Luis Valley. Today, many of the  wetlands are dry due to a lower ground water table and decreased rain and snow runoff from the mountains.

The Blanca Wetlands – a part of this wetlands network – is making a comeback through the efforts of the Bureau of Land Management and its many partners. Ponds, marshes, playas, wet meadows, and uplands intermingle at Blanca Wetlands to provide rich and diverse habitats for wildlife – and a haven for people.

Blanca Wetlands is an Area of Criticial Environmental Concern

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 is seeking public input to guide an environmental analysis for a proposal to expand the Blanca Wetlands ACEC.

As part of this project, the BLM is completing an environmental assessment (EA) to analyze the potential impacts of enlarging the Wetlands ACEC. The EA presents 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 would enlarge the ACEC from 9,714 acres to 122,762 acres. No new water rights would be created and no land ownership jurisdictions would change should the boundary be expanded.
