Klamath Siskiyou Oak Network

Projects

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.

Strategic Conservation Planning with the Klamath Siskiyou Oak Network

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 years, with an additional 3,400 acres of restoration planned for the next several years. Over the last few months, with the support of a grant from the Oregon Watershed Enhancement Board, KSON has been developing a Strategic Action Plan for oak conservation in the Klamath-Siskiyou Bioregion. Strategic conservation planning is a science-based process that helps regional conservation partnerships plan for the future. Why prioritize? Both time and conservation dollars are limited, so identifying the projects that have the most impact is important. Strategic planning helps identify the species, habitats, and places …

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 crown dieback in the oaks and reduces acorn production.  Over time as more of the oak crown becomes shaded the oaks eventually die.  On the dry east side of the Scott River Valley in Siskiyou Co., CA, juniper encroachment poses a major threat to the health and function of oak habitats.  To address this issue the U. S. Fish and Wildlife Service, the Natural Resources Conservation Service, and Lomakatsi Restoration Project partnered with the Scott River Ranch to reduce juniper encroachment on 91 acres of oak habitats.  Treatments focused on…

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 high value resources (e.g. homes).       KSON identified the research need to inform landscape and site-level planning when chaparral reduction is warranted to reduce fire risk and meet oak restoration objectives. Klamath Bird Observatory research found that retaining large patches of chaparral and prioritizing retention in a landscape context will help ensure sufficient habitat remains for chaparral-associated birds. As part of KSON’s adaptive management strategy, management recommendations are being incorporated into restoration design.  The results from our study…
