Potential Conservation Areas (PCAs) are delineated around important elements of biodiversity (plants, animals or natural communities). The list below includes all PCAs within the Alamosa-Trinchera created for wetland and riparian dependent elements. This list represents wetlands and riparian areas with the highest known biodiversity value in the area.
