Echinocereus adustus, E. pamanesii and E. schereri are three morphological related, little known species from northwestern Mexico. In order to assess their conservation status, data on their distribution and ecological conditions were gathered from herbarium specimens, field work and databases. A data matrix of about 140 records was obtained. After curating those, eighty-eight records were kept of E. adustus subsp. adustus, E. adustus subsp. schwarzii, E. pamanesii and E. shereri. Distribution maps were generated on biogeographic provinces and ecoregions, and maps of the Area of Occupancy (AOO) and Extent of Occurrence (EOO) were prepared for each taxon. We propose to update the conservation status to Endangered for E. adustus (which has a wide distribution but very restricted occupation area) and E. schereri (restricted distribution and locally very rare), and to Near Threathened for E. pamanesii, which has a small Area of Occupancy and Extent of Occurrence but is locally common in an area not exposed to agricultural activities.
