Alyssa is studying the long-term impacts of logging on headwater amphibian populations, specifically occupancy. Her research takes place in two adjacent watersheds in the Redwood National and State Parks in Northern California. One watershed is highly degraded from historic logging practices and the other is a pristine late-seral watershed untouched by logging. Her field work, in combination with various other student and park employee-run studies, will form the baseline for a restoration project aimed at restoring the logged watershed.
