A map of the sites surveyed for witches, Tetlin National Wildlife Refuge, Alaska.
Tetlin Witch Report
Introduction
Invasive witches have become a management concern at Tetlin National Wildlife Refuge. As such, there is a need to estimate witch occurrence within the Refuge.
Methods
Data Collection
We visited a sample randomly distributed sites across Tetlin Refuge. At each site, we spent one hour looking and listening for witches. We revisited each site eight times.
Model
We estimated witch occupancy and detection using a single-season occupancy model. We used the unmarked R package. [blah, blah, blah]
Results
We surveyed a total of 100 sites. The average distance to water at our sites was 1137.03 m. The average distance to forest at our sites was 59.41 m.
We observed witches on 193 of 800 site visits, for a naive occupancy of 0.24.
