Denver Botanic Gardens Research staff initiated a demographic study on two sites in 2004 and has been collecting data annually. They are also conducting counts throughout the entire range to establish trends of the species. Data collected by Denver Botanic Gardens Research staff indicates that the number of plants has been stable from 2004-2008 within its limited available habitat.

Eriogonum brandegeei was previously a candidate for Federal Listing but was removed in 1996. Some of its range is found in a Colorado Natural Area, and is managed to protect the population and its habitat.

Potential habitat on Canon City District BLM land was determined using aerial photographs, soil maps, and topographic maps. All potential habitat in this study area was searched during the field season of 1995. Remaining potential habitat should be determined and search on adjacent Forest Service and private lands, especially between Salida and Buena Vista. Remaining potential habitat is likely scarce (NatureServe 2008).
