What percentage of the mares on each HMA foal each year, and whats the survival rate of the foals?
The percentage of mares that foal each year and the survival rate of the foals per year depends on the HMA and environmental conditions such as drought and available forage. The BLM claims that the reproduction rate is about 20-24% per year. But some years that reproduction rate may be 5% or less. This does not take into consideration that although a foal is born it may not survive to adulthood.
