Endangered Species Act at 50

It's the 50th anniversary of the Endangered Species Act.  While it's been an unqualified success for some species, notably charismatic ones, I have my doubts about its overall effectiveness.  We seem to struggle to protect specialized habitats for species that have been identified, but we do little to protect large enough contiguous areas to preserve biodiversity in general.  

NatureServe in conjunction with the NM Dept. of Game and Fish has developed an Environmental Review Tool.  One of its layers is Crucial Habitat that focuses on areas that need protection.  Here's the zoomed in view of the area northwest of Albuquerque.
