Wolf Creek Watershed
20 miles long
78 sq miles
3,000 ft1,200 ft
Effects of Geography (and Geology)Low Sierra mountain setting means that not much of the precipitation in the watershed falls as snowTop third of watershed flows East to WestBottom two thirds flow North to SouthGeologic diversity as well volcanic flows, granitic strata, gabbro and serpentine soils
BiodiversityGeography and geology provide biotic diversityThe watershed has at least seven general types of plant communitiesThe plant communities in turn support diverse animal communities
Plant CommunitiesAnnual Grass Blue Oak Woodland Blue Oak-Foothill Pine Closed Cone Pine-Cypress Douglas Fir Mixed Chaparral Montane Chaparral Montane Hardwood Montane Hardwood-Conifer Montane Riparian Ponderosa Pine Sierran Mixed Conifer Wet Meadow
Rare Habitat Low-Altitude Mountain Meadows
The Diverse History of Wolf Creek500 7000 years of continuous habitation by Maidu peoplesPeople of European Origin enter the area the Emigrant Trail runs along South Wolf CreekDiscovery of gold in Wolf CreekA hundred years of gold mining, followed by:Sixty years of recovery
The Diversity of ImpactsThe main reach of upper Wolf Creek, and South Fork of Wolf Creek, have been heavily effected by miningSouth Wolf Creek had almost no miningWolf Creek around Grass Valley is urbanizedSouth Wolf Creek is almost entirely rural
The Diversity of Possible FuturesThe Wolf Creek watershed is being rapidly developedMuch of the watershed could soon be like the urban reach in Grass ValleyThere are still open spaces that can be preservedWhat kind of future will we choose for the Wolf Creek watershed?
