Denver Botanic Gardens undertook a floristic inventory of the Baca National Wildlife Refuge in 2012 and 2013 to build on Pam Regensberg’s 2006 inventory of the refuge. Our recent inventory combined with the earlier inventory (Regensberg 2007) should provide land managers a plant diversity baseline for the refuge. Regensberg (2007) provides thorough and detailed descriptions of climate, geology, soils, water resources and the vegetation communities on the refuge. Therefore, we will not repeat that information in this report but rather focus on areas of note or noteworthy species of particular interest based on recent field work. We also provide an updated species list available in multiple formats including an online checklist, which is the most valuable for helping identify species on the property.
