Why Oaks?

Oaks in the Klamath Siskiyou Bioregion…

What makes them so special?

  • Diversity of vegetation types, including woodland, chaparral, mixed oak/conifer
  • Contain some of the most biodiverse habitat in southern Oregon and northern California (many endemic plants, >300 vertebrate species)

  • Oak woodlands are an Oregon Conservation Strategy Habitat (ODFW 2006).

  • Oaks provided critical physical and cultural resources for native people.

  • Fire-adapted;  were maintained using burning as a management tool.

  • A mosaic of oak vegetation provides fire resilience to the landscape.

  • Oak woodlands have experienced losses up to 33% in California and up to 95% in Oregon.

  • Threats include conifer encroachment, oak densification, intense fire, overgrazing, invasive exotic species, development and fragmentation
