I drew the Naches/Corral Pass permit last year so I can give you a recent report on that area as I kept very detailed notes. In my 10 days afield I estimated that I looked at 80 different goats in the two areas; 20 nannies, 16 billies, 27 kids, and 17 un-sexed adults. Even if ALL unsexed adults are nannies that is a pretty decent kid:nanny ratio of 73:100.
The opinion that I shared with WDWF was to keep the permit levels conservative for the next 3-5 years and then slowly increase. Thanks to the cooperative effort of WAFNAWS, Seattle SCI, Seattle Sportsmens Foundation, et al there is a large survey project in progress to see exactly the status of each goat herd. Once some numbers are determined hopefully WDFW can implement a plan to help recover the overall population.
