The Campaign Against America’s Wild Horses indicated in the September update that 89 mares received 89 doses of Zonastat-H during the month, 26 given as a primer and 63 as a booster. If you can’t access the document, click here.
Over the life of the program, 1,949 mares have received 8,116 doses of the pesticide.
The report will be submitted to the Nevada Department of Agriculture.
Of the 163 foals born this year in the primary target zone, 80 have died.
The causes of death were not discussed but predation is likely a factor.
As for the long-term population goal and how many horses they intend to eradicate, the advocates are silent.
No comments about herd demographics.
No discussion of sterility and the growing risk thereof.
The current population is thought to be 3,513 with 356 listed as missing, compared to 3,559 in August, including 395 listed as missing.
A goal for October is to maximize booster treatments, allowing for continued population reduction, equivalent to bait trap removal or helicopter roundups.
