In 2012, ERO completed a regional Habitat Conservation Plan (HCP) for Colorado’s San Luis Valley. The HCP provides a framework for conservation of riparian habitat that supports the endangered southwestern willow flycatcher while also providing regulatory coverage to landowners and local governments as they conduct historic and routine agricultural and land management practices. This complex multi-stakeholder process involved collaboration with six counties, four principal municipalities, Colorado Parks and Wildlife, U.S. Fish and Wildlife Service, and several nonprofit partners.
