Barred owls (Strix varia) have reached high densities within the range of the northern spotted owl (S. occidentalis caurina) and are rapidly increasing in number within the range of the California spotted owl (S. o. occidentalis). Encroaching populations of barred owls pose a significant competitive threat to the viability of both spotted owl subspecies in California. In response, the Director of the California Department of Fish and Wildlife (CDFW) convened the California Barred Owl Science Team (BOST) to identify and address the threat posed by barred owls to spotted owls in California. BOST is composed of subject matter scientists with a goal to provide objective scientific review and recommendations to CDFW to promote the recovery and conservation of spotted owls in California. In this document, BOST identifies, describes, and prioritizes key research needs for barred owls that have the potential to benefit the conservation of spotted owls in California. Key research needs were identified from multiple in-person and remote meetings of BOST, with considerable input from attending representatives from state and federal natural resource agencies. BOST and liaisons recognize that periodic updates of this document will likely be required as more is learned about the ecology of barred owls in California and research needs and priorities evolve. Research that BOST deemed the most likely to provide a rigorous scientific basis for reducing barred owl populations included experimental removals, along with ecological studies expected to generate information that would provide avenues for the effective management of barred owls. Other high priority research needs include research using biological samples obtained during experimental removals to better understand the ecology of barred owls and the threats they pose to spotted owls and associated wildlife. We conclude the document with a discussion of how projects are related to the State Wildlife Action Plan. In Appendix I, we discuss considerations for maximizing the success of proposed removal experiments and ecological research on barred owls.

A magnificent active volcano, Mount Rainier ascends to 14,410 feet above sea level--the highest in Washington State. The source of five major rivers, it has more glaciers than any other peak in the contiguous U.S. Its slopes are home to ancient forests, spectacular subalpine meadows, and unique, captivating creatures. In Tahoma and Its People, a passionate, informed, hands-on science educator presents a natural and environmental history of Mount Rainier National Park and the surrounding region. Jeff Antonelis-Lapp explores geologic processes that create and alter landscapes, interrelationships within and between plant and animal communities, weather and climate influences on ecosystems, and what linked the iconic mountain with the people who traveled to it for millennia. He intersperses his own direct observation and study of organisms, as well as personal interactions with rangers, archaeologists, a master Native American weaver, and others. He covers a plethora of topics: geology, archaeology, indigenous villages and use of resources, climate and glacier studies, alpine and forest ecology, rivers, watershed dynamics, keystone species, threatened wildlife, geological hazards, and current resource management. Numerous color illustrations, maps, and figures supplement the text. 2020 Banff Mountain Book Competition Finalist, Mountain Environment and Natural History category

Evidence indicates that competition with newly established barred owls (Strix varia) is causing rapid declines in populations of northern spotted owls (Strix occidentalis caurina), and that the long-term persistence of spotted owls may be in question without additional management intervention. A pilot study in California showed that lethal removal of barred owls in combination with habitat conservation may be able to slow or even reverse population declines of spotted owls at local scales, but it remains unknown whether similar results can be obtained in larger areas with different forest conditions and where barred owls are more abundant. In 2015, we implemented a before-after-control-impact (BACI) experimental design on two study areas in Oregon and Washington with at least 20 years of pre-treatment demographic data on spotted owls to determine if removal of barred owls can improve population trends of spatially associated spotted owls. Here we provide an overview of our research accomplishments and preliminary results in Oregon and Washington in 2015.
