CESAR’s initial examination of the public record related to the listing of the Hookless Cactus (Sclerocactus glaucus) identified little to no data or verifiable science supporting some of the Sclerocactus conservation actions required by BLM in its land management plans and permitting. This led to CESAR’s review of the listing and supporting documents in an attempt to identify data and analysis to support the conservation actions.
Instead CESAR scientists identified misrepresentations of the science, analysis, and data in the original listing as well as the subsequent division of the original listed species, Sclerocactus glaucus, into three separate species (S. glaucus, S. wetlandicus, and S. brevispinus). Finally, CESAR conducted an independent review of the threats to the species using the available data. Our own review and analysis using BLM data, which is detailed in the appendices, contradicts most of the ‘science’ contained in the FWS regulatory documents.
CESAR's Hookless Cactus report documents the almost complete absence of any verifiable scientific basis for the original listing and subsequent division of the Sclerocactus glaucus into three species and a corresponding lack of data to support for any but the most obvious conservation actions. As a consequence, of its findings, CESAR recommends several ‘next steps’ to ensure that scarce conservation dollars are spent wisely and on appropriate conservation actions.
