Detailed Description

Use the green slider tool in the center to view locations of barred owl sightings recorded during 2015 and 2020 owl monitoring activities at the Oregon Coast Range study area. Barred owls were lethally removed from the areas highlighted in pink. Preliminary results indicate that removals have significantly increased the site-level extinction probability of barred owls and decreased site-occupancy across three different experimental study areas.
