Here's an idea concerning BLM's wild horse and burro program. Why not get congress to pass a national microchipping law for horses. All those individauls who own a horse have to get it micro-chipped and all those in the wild horse and burro program. That way they can be tracked with a digital profile that is located in the microchip. Very similar to the micro chips for dogs and cats. When the horse is bought or sold or adopted the data would be updated. Add GPS and hook it up to Google Earth and the Public could "see" their "wild" horse or burro anytime on the web.
Then when they are abandoned by their owner or run away into the "wild" and end up in the herds of the West and are rounded up by the wild horse and burro program you can call the owners and tell them to come get their horse. If they refuse charge them for room and board of their animal.
This would help in several ways. 1) lost horses could be returned to owners; 2) BLM would know what tax payer to charge for taking care of the horse; and 3) That most of the "wild horses and burros" are not really wild, but abandoned or lost and thus stray animals.
Then there would be data concerning the origin of these horses and burros.
