They were not transplanted or released.
Joe/DFGELK,
To show my ignorance, how are the Sierra Nevada Mtns different than the Rockies in CO, WY, UT, MT, and the Mtns of Id, WA, and OR (that border and share the Cascades) with CA? Is it the lack or possible difference of surrounding habitat?
Thanks ...Mike
Can help some-- It is also the age of the mountain ranges with the Sierra being far younger. Fly over Sierra (mostly granite or forest) compared to Rockies (large aspen parklands and open meadow areas). When we started my project near Sonora Pass in the 80s, we invited 3 of the top ungulate ecologists in the country (Phil Urness-UT, Jack Ward Thomas-USFS-OR, and Richard Mackie-MSU-MT) to spend a few days touring (poker and drinking.>> sheesh) our project area. They were surprised that we (CA) allowed domestic livestock grazing at all because of the lack of abundant foraging habitat for a grazer. Fun times. those guys were hopefully not the last of "old school" thinking. Eric
