A small grassland patch surrounded by open space, even if the surrounding fields are not grasslands, is better for grassland birds than a grassland surrounded by trees. Target birds are those listed as "probably" or "confirmed" breeding in the 2005 Breeding Bird Atlas (BBA) Block where the subject field is located. Colorado Parks and Wildlife is a nationally recognized leader in conservation, outdoor recreation and wildlife management. As exotic species have replaced the native grassland, bird species associated with grassland habitats in the Baldwin Hills, such as the Burrowing Owl, have become very rare and are most likely transients.
