Klamath Siskiyou Oak Network


KSON was formed to address oak restoration needs and challenges. Because 65% of oak habitat in southern Oregon and northern California is on private land, the Klamath Siskiyou Oak Network (KSON) partnership has secured $7.5 million to restore more than 6,400 acres of oak woodland across federal and private lands, largely supported by NRCS partnership programs and USFWS Partners for Fish and Wildlife Program.

Oak habitats support a high diversity of birds and other wildlife species, but are threatened by conifer encroachment, invasive species, and fragmentation. Since 2011, KSON partners have already successfully leveraged millions of dollars of public and non-federal resources to restore 3,000 acres of oak woodland in southern Oregon and northern California in the last five […]

Oak Woodland Restoration on the Scott River Ranch, Siskiyou Co., CA

California’s oak woodlands have been dramatically reduced over the past two centuries.  Numerous factors have contributed to this decline including the encroachment of coniferous species into oak habitats following the disruption of historic fire regimes.   Oaks are slow-growing, shade-intolerant species that can be rapidly overtopped and suppressed by faster growing conifers.  Initially, suppression leads to […]

Using Birds as Indicators in Oak-Chaparral Restoration Projects

A number of oak obligate bird species are in decline, making oak habitat restoration a priority.  Oak-chaparral plant communities, characterized by open grown oaks with a thick shrub understory, also provide important habitat for wildlife but sometimes require reduction during restoration as chaparral can burn at high severity and threaten large, old oaks and other […]
