According to BLM officials in AZ , they are required to remove any burros deemed a ‘nuisance’ by private parties or by other federal, state, county…. officials under section 1334 of the WH & B Act of 1971 which applies to burros which have left the relative safety of BLM -managed public lands for the comparative non-safety of other public or private lands. Unfortunately, there doesn’t appear to be any obligation or even suggestion in Sect 1334 that BLM seek to find remedies other than removal once a complaint has been formally filed, -no matter how simple or inexpensive they might be. Hence alternate solutions like selective fencing, or the maintenance of water sources on BLM public lands, are categorically rejected or ignored in favor of the tried and true approach, the helicopter gather, with all of its costs and humane issues, in the interest of expediency.
