Developing optimal post-fire restoration strategies to build ecosystem resilience- Stephanie Yelenik

A widespread challenge for National Parks is restoring post-fire habitats to native states that are resilient to further fire. Especially in
areas with a history of grazing, exotic grasses perpetuate ‘grass-fire’ cycles by acting as fire carriers between habitats, including forests.

Monitoring Bird and Rat Behavior to Improve Invasive Species Management

Introduced rats are notorious predators of birds and their nests worldwide, but especially on remote islands.

Since Western contact in 1778, two additional rat species have become established in Hawai‘i, including the highly...
