Sadly, wild sheep numbers are down in many of their ranges. For our thinhorns up North, environmental factors, some of which are beyond short-term human control, have taken a toll in recent years. In other wild sheep ranges, fragmentation, contraction, and loss of habitat, both from a changing climate and land use policies (fire suppression, conifer/shrub encroachment, human footprint, public land grazing allotments, feral horses and burros), as well as disease from exotic and domestic ungulates in bighorn range, are all contributing factors.  

What can we do? Ensuring wild sheep have quality habitat is #1, but can we improve the resiliency of wild sheep to environmental factors? Can we “grow” wild sheep? These are contemporary and often controversial topics that wild sheep advocates and some agency/ministry wild sheep managers are trying to define and address.  

In this episode of Sheep Fever, co-host Gray N. Thornton speaks with WSF’s “Tres Amigos of Conservation” - VP of Conservation Kevin Hurley, Conservation Director Kurt Alt, and retired Conservation Director Clay Brewer, on these topics.

With nearly 150 years of combined wild sheep management and experience, the three speak of “growing” desert bighorn in the US southwest and Mexico and the successes, challenges, and failures experienced. They also speak of attempts to do the same with Rocky Mountain bighorns, and whether intensive management practices for desert sheep (water developments, captive propagation facilities, supplemental nutrition and minerals, etc.) are feasible, practical, sustainable, or even possible for thinhorn sheep.
