How the marbled Murrelet is affected by the density of the redwood?

The marbled murrelet, a seabird that nests in old-growth forests, relies on mature redwood trees for its breeding habitat. High-density redwood stands provide the necessary structural elements, such as large branches and platforms, where murrelets can safely nest. However, as forest density changes due to logging or other disturbances, the availability of suitable nesting sites can diminish, negatively impacting murrelet populations. Thus, maintaining healthy, dense redwood habitats is crucial for the conservation of this species.
