Assessments of invasive species and seabird habitat in the oregon coast national wildlife refuge complexperiod of performance: 9 19 2025 - 9 18 2026ABSTRACT summary: the purpose of this award is to address knowledge gaps regarding historical and current invasive species dynamics in the oregon coast national wildlife refuge complex and to identify the influence of invasive vegetation on burrow-nesting seabird occupancy and habitat use.activities to be performed - 1) establish current and vegetative reference conditions using aerial imagery and a vegetative dynamics model and 2) relate burrow occupancy to specific habitat features, thus establishing a baseline for the evolving management and naturally occurring ecological change of seabird habitat.deliverables and expected outcomes - all raw data from 2024 and 2025 burrow occupancy and habitat sampling efforts in oregon islands nwrc all post-processed and georeferenced aerial imagery flown in 2024 and 2025 habitat classification maps derived from publicly available imagery and aerial photography a final report outlining findings from the habitat change analysis, vegetation dynamics model, and analysis of burrow nesting survey data intended beneficiary(IES) -this project is conducted under the auspices of the U.S. Fish and wildlife service. Funding will be awarded to oregon state university to accomplish all aforementioned goals and objectives of the project.
