renowned scientist dr E. Gus Cothran issued a report on the genetics of the Pryor Mountain Wild Horse Herd - reported The Could Foundation.
Please note that this is the most famous mustang/wild horse herd in the US. Documentary films have been made out these walking relics of Spanish horse breeding in the Americas, especially following the life of one stallion named Cloud - ''Cloud: Wild Stallion of the Rockies'' ( 1995 ) and ''Cloud's Legacy: The Wild Stallion Returns'' (2003).
The Cloud Foundation has a nice video library and photo gallery devoted to these horses.
Well, the report has plenty of important and alarming data summarised by dr Cothran:
Dr Cothran onclusions:
''Current variability levels are high enough that no immediate action is needed . However, there has been a general trend for a decline in variations levels of the herds. If the trend continues the variability levels of the herd could drop below the feral average within the next five to ten years.''
“The best way to maintain the current levels (of genetic variability) would be to increase population size if range conditions allow.
