  1. Wolf Creek Community AllianceWolf Creek is Special! • It’s all about diversity: • Geography • Geology • Biodiversity • History • Human Impacts

  2. 3,000 ft Wolf Creek Watershed20 miles long50,000 acres78 sq miles 1,200 ft

  3. Effects of Geography (and Geology) • Low Sierra mountain setting means that not much of the precipitation in the watershed falls as snow • Top third of watershed flows East to West • Bottom two thirds flow North to South • Geologic diversity as well – volcanic flows, granitic strata, gabbro and serpentine soils

  4. Biodiversity • Geography and geology provide biotic diversity • The watershed has at least seven general types of plant communities • The plant communities in turn support diverse animal communities

  5. Plant Communities • Annual 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

  6. Rare Plants

  7. Rare Animals

  8. Rare Habitat – Low-Altitude Mountain Meadows

  9. The Diverse History of Wolf Creek • 500 – 7000 years of continuous habitation by Maidu peoples • People of European Origin enter the area – the Emigrant Trail runs along South Wolf Creek • Discovery of gold in Wolf Creek • A hundred years of gold mining, followed by: • Sixty years of recovery

  10. The Diversity of Impacts • The main reach of upper Wolf Creek, and South Fork of Wolf Creek, have been heavily effected by mining • South Wolf Creek had almost no mining • Wolf Creek around Grass Valley is urbanized • South Wolf Creek is almost entirely rural

  11. The Diversity of Possible Futures • The Wolf Creek watershed is being rapidly developed • Much of the watershed could soon be like the urban reach in Grass Valley • There are still open spaces that can be preserved… • What kind of future will we choose for the Wolf Creek watershed?
