Programs reduce densities of birds preying on threatened marbled murrelets

Research funded by Save the Redwoods League suggests that programs designed to help reduce jay populations in areas where marbled murrelets nest, including old-growth coast redwood forests, will give these threatened seabirds a better chance at successful reproduction.

Genes Could Influence Trees’ Conservation

Fire is an example of a disturbance event that redwoods face.

Coast Redwoods’ Response to Disturbance Events

on

In 2006, Save the Redwoods League recruited eight scientists to survey scientific literature about how coast redwood forests respond to “disturbance events” such as fires, windstorms and floods. The scientists considered how redwoods fit into two broad categories of trees: those that need major disturbances to perpetuate themselves and those that don’t. The seedlings of disturbance-dependent trees germinate in open spaces, grow quickly to outcompete other vegetation and tend to form even-age stands. Species that don’t need disturbances tend to be shade tolerant, slower growing and longer lived.  They usually grow in uneven-age stands.
