Who We Are

A photo of Wild Horse Annie
International Society for the Protection of Mustangs and Burros (ISPMB) led the way in creating the first ever wild horse adoption program in 1968, which led to the creation of the federal Adopt-A-Horse/Burro program operated by the Bureau of Land Management (BLM). ISPMB has been and continues to be innovative in the field of wild horse and burro protection through research studies, legislation and continued involvement with government participation.

Under the leadership of our first president, Velma Johnston, affectionately known as Wild Horse Annie, ISPMB and Annie were responsible for the passage of Federal Legislation in 1971 (PL 92-195) that gave protection to wild horses and burros on public lands from death and harassment. 

How You Can Help

ISPMB has been an empowering force influencing global attitudes and catalyzing actions for the protection, preservation, and understanding of wild horses and burros and their habitat since 1960. As a non-profit organization, we rely entirely on donations and volunteers to continue our mission to protect, preserve, and rescue these magnificent creatures!

ISPMB is a 501(c)3 not for profit organization and all donations are tax-deductible. We can put any size donation to work and Thank you for your generosity.

  • At the International Society for the Protection of Mustang and Burros, we are an effective international leader in our field because we have earned the respect and credibility of the many diverse participants in the Wild Horse and Burro program. Our approach to problem-solving is unique among organizations. Rather than capitalizing on fear as a motivator to produce change or create funding, we believe that fear must be dispelled to affect positive changes accepted by all. Our main thrust is one of education and of becoming a model, a way of “being” on this planet we call Mother Earth. One can make no greater impression than to lead by example. ISPMB honors the wild horse and burro and realizes the interdependence of all living things in this universe.
