Project Abstract Summarytitle Developing a Willamette Valley Survey Protocol to Monitor Distribution, Abundance, and Population Trends of the Federally Threatened Streaked Horned Lark Abstract Tracking the Status and Progress of Threatened and Endangered Species Recovery Efforts Requires Information on the Species Distribution, Abundance, and Population Trends the Streaked Horned Lark Shla Is a Federally Threatened Subspecies That Occurs in Early Successional Habitat, Including Agricultural Lands, in Washington and Oregon Pearson Et Al 2016 Developed a Standardized Monitoring Protocol for Use at Occupied Sites With Well Defined Boundaries and to Which Access Is Allowed E G , Airfields, Prairies, Columbia River Deposition Islands However, a Monitoring Protocol for Shlas on Private Lands in Agricultural Habitats of the Willamette Valley, or, Where 50 of the Shla S Range Wide Population Likely Breeds, Is Lacking Accordingly, the Development of a Monitoring Protocol for Shlas in the Willamette Valley Is Identified as a Critical Need in the Species Draft Recovery Plan and Is the 1 Ranked Priority in the 2021 Shla Action Plan in This Proposal, We Outline a Multi Phased Proposal That Develops a Road Based Survey Protocol for Shlas in This Region Results From This Project Will Be Used to Recommend a Full Scale Implementation Plan for Monitoring Shla in the Willamette Valley Capable of Estimating Population Size and Tracking Population Trends in Combination With the Pearson Et Al 2016 Protocol, It Will Be Possible to Estimate Range Wide Population Abundance and Trends This Information Would Yield a Better Understanding of Shla Population Dynamics, Which Is Necessary to Support Recovery and Conservation of the Subspecies
