Our goal at ISPMB is to prevent the elimination of unique herds and to find a solution that would help to raise the public’s awareness of the need to protect wild horses and burros on public lands. At present, ISPMB is creating a model management program for wild horses in our country and currently manages three unique wild horse herds – the White Sands herd, the Gila herd, and the Catnip herd.
Currently, ISPMB is continuing its observation and study of the herds so that a model management program can be derived. Fertility and recruitment rates are observed along with behaviors of bands and their interaction with each other. Each herd is blood typed and DNA tested. Right now the herds are far more genetically diverse compared to any breed of domestic horse in our country.
Wild horses and burros would not exist in our country today if it weren’t for the efforts of ISPMB and our first president, Wild Horse Annie, who were instrumental in getting congress to pass federal legislation in 1971 that gave protection from death and harassment of wild horses and burros on public land.

This behavior could lead to the loss of survival of wild herds over the long term!
We know that our studies will lead to the end of helicopter gathers by the BLM. That BLM will only be able to remove horses through bait or water trapping leaving band structures intact.

ISPMB has 12 years of study on herd structures which ultimately could help the BLM make better decisions as to how roundups should occur.
We need to keep the herds together for further study.
ISPMB has been documenting wild horse behaviors on our wild herds now for eleven years. We have enough documentation to show that BLM's constant removals of wild horses have contributed the destruction the herds' social structures creating an increase in wild horse numbers due to the deterioration of their education system.
Simply put - when wild horses are rounded up and then returned to the wild (selective removals) - leaving the gates open and horses to fend for themselves as they return to their habitat areas (contracepted or not)- the younger stallions will take the opportunity to steal mares away from the older stallions that truly contain the herd wisdom. Over time, mentoring of the bands by younger stallions has led to breeding younger and younger fillies.
