When the trees are cut down it takes away the habitat of the plants and animals. It also reduces the space for the indigenous people who have lived there for thousands of years.

This way of life has died out with contact from incomers.

Some native groups suffered greatly from diseases which they had no resistance to.

Threats Intensive commercial logging has destroyed more than 90% of the native forests of this ecoregion. The immense size of the mighty redwood trees, and the beauty of their wood, has made them a target for loggers for more than a century. Even logging in surrounding watersheds can have severe repercussions for redwood groves, since it can cause severe flooding, fires, and sedimentation. The spread of urban areas between Monterey and San Francisco, along with the introduction of exotic plants into these ancient forests, exacerbate the problems. Cruise ships can lead to pollution, as well as disturbing whales and other marine mammals. Other threats include pollution from pulp mills and mines. Introduced beavers are also creating problems for native wildlife. Their damming of small streams is making it difficult for Coho salmon to travel upstream and spawn. Similarly, introduced rats, squirrels, and raccoons have reduced the size of seabird colonies as they prey on eggs and young birds.
