In partnership with the Umpqua Oak Partnership (UOP), the Klamath Siskiyou Oak Network (KSON) has released version 3.0 of “Restoring Oak Habitats in Southern Oregon and Northern California: A Guide for Private Landowners”. The funding for this landowner guide was from the Secure Rural Schools Title II program administered by the Bureau of Land Management Western Oregon Resource Advisory Committee.

Our region holds onto Oregon’s largest remaining section of oak habitat. With the majority of it owned by private landowners. Since 2017, southern Oregon and northern California landowners have protected and restored more than 5,000 acres of oak and prairie habitat.

Northwest oak and prairie landscapes are among the most drought-tolerant, wildfire-resilient native habitats in North America and oak trees play a key role in the ecosystem. If they are not restored, protected, and maintained, important natural processes could be lost forever. With over 300 species of wildlife using oak habitats during their life cycle, continued habitat loss and degradation will result in more of these species becoming vulnerable. Currently, 45 of those oak-associated species are already considered to be ‘at-risk’. Additionally, overstocked and unmanaged oak stands present an increased risk of unnaturally severe wildfire which not only results in habitat loss but threatens residences and rural communities.

“As both a landowner located in the Umpqua Basin and one of the authors, I am excited to see this new version of the landowner guide for managing oak habitats. This version of the guide has been updated to include the latest information on managing and restoring oaks and will be a valuable resource for landowners whether you own less than one acre or thousands of acres”. – Steve Denney, Umpqua Oak Partnership Coordinator.

This landowner guide describes how to apply conservation practices for Oregon white oak and California black oak habitats on private lands in southern Oregon and northern California. The document discusses the importance and history of oak habitats across three ecoregions and provides detailed conservation guidelines for oak habitat restoration, integrating Western science and Indigenous Traditional Ecological Knowledge.

The guide includes supplemental resources for the restoration-minded private landowner, including a list of organizations that will assist with private land restoration as well as step-by-step instructions for monitoring birds on your land to track the return of wildlife following oak restoration activities. An exciting opportunity exists for landowners and conservation partners to work together to restore native oak systems and their diverse wildlife communities to reverse these trends.

The Klamath Siskiyou Oak Network (KSON) is a regional collaboration between local agencies, tribes, and non-profit organizations that works to conserve oak ecosystems on private and public lands in southern Oregon and northern California. Since 2011, KSON partners have accomplished thousands of acres of strategic ecological restoration to enhance oak habitat, build climate resilience, bolster cultural resources, and reduce wildfire risk to the ecosystem and communities.

The Umpqua Oak Partnership (UOP) is a collaborative regional partnership of landowners, tribes, agencies, and organizations working together to preserve and promote healthy oak habitats in Douglas County. UOP’s mission is to work to bring people together around oaks, help keep farms and ranches in the family, connect landowners to programs and funding, and share information.

KBO tracks the first Oregon Vesper Sparrows!

The unique Oregon subspecies of Vesper Sparrow, roughly estimated at just 2,000 birds, is of conservation concern. It is currently under review for listing under the Endangered Species Act because of its small population size and declining trend. One of the biggest challenges in identifying ways to help migratory species is the fact that we don’t know where they are for most of the year. Vesper Sparrows breeding in Oregon are only here for about half the year, from mid-April to early October. Because different subspecies of Vesper Sparrow mix on the wintering grounds in California and are not visually distinguishable, until now, we only had a rough idea of where Oregon Vesper Sparrows spend the non-breeding months. This study will help answer questions essential for future conservation efforts – where are these birds going during migration and winter, and what challenges might they face there?

To address this critical knowledge gap, we expanded KBO’s ongoing Oregon Vesper Sparrow research to include using miniaturized archival GPS tags to track the migration of sparrows breeding in the Rogue Basin. In 2020, we captured 10 males via target-netting at our Lily Glen study site, color-banded them, and deployed GPS tags using a leg-loop harness attachment (for more details and photos of this process, see here ). In 2021, we located and recaptured four of these birds to retrieve tags and stored data. Three of the tags successfully recorded these individuals’ fall migration and/or wintering locations; one also contained the spring migration track!

Non-breeding season movements have never been tracked in this subspecies before, and results from these first three birds are incredibly interesting in their variation. You may have already followed the adventures of Po, Gram, and Affy in our recent series of Facebook posts, where we learned where they traveled during migration, but we will recap the highlights here and below in a video. One male (Po; in green) departed Lily Glen on Sept 19 on what appears to be a “false start” migration attempt – he spent one night about 25 km southwest of Tule Lake and then headed right back to Lily Glen – a behavior that we hadn’t recorded before, and in fact, would have been nearly impossible to observe without the GPS tag data. He left Lily Glen again on Sept 24 and sped down to his wintering grounds in just two days. This was also the only individual for whom we also captured spring migration – Po left his overwintering area on the evening of Apr 9, made two short stopovers just east of Vina, CA, and Redding, CA, and was back setting up his territory at Lily Glen by Apr 15.

Another male (Gram, in blue) left Lily Glen on Sept 19 and spent two weeks on an extended fall stopover outside of Chico, CA, before arriving at his wintering grounds in October. A third male (Affy; in pink) chose a more westerly route and had multiple short fall stopovers, including at Sutter Butte, an interesting geological formation made of eroded volcanic lava domes outside of Yuba City that provides a habitat island in the highly developed Central Valley. Unfortunately, Affy’s GPS tag stopped functioning mid-October, so we do not know his final wintering location. The two birds we have wintering locations for (Po and Gram) spent the winter near Raymond, CA, and El Rancho, CA, in what appears to be oak savannah habitat in the western foothills of the Sierra Nevada.

This study is the first to identify precise migratory stopover sites and overwintering areas used by this imperiled subspecies, and it addresses a critical information gap for future conservation efforts. So far, it seems like the Oregon Vesper Sparrows are using grassland and oak savannah habitat in the foothills east and west of the Central Valley as a stopover and overwintering habitat and avoiding the heavily agricultural Central Valley. We retrieved additional GPS tags in 2023, and after analyzing the data, we will use this information to assess whether conservation actions are warranted at non-breeding sites.

The Bureau of Land Management, Carpenter Foundation, Oregon Conservation and Recreation Fund, and Oregon Wildlife Foundation supported this GPS-tracking work.
