Muir Woods National Park is the home of the Northern Spotted Owl. It has been listed as an endangered species since 1990 due to the loss of habitat. The Northern Spotted Owls rely on abandoned nests or tree cavities or broken tree tops or accumulated debris for its nesting place. Since these favored nesting spots are most likely to be found among mature trees of densely populated forests which are now being cut for logging and for urban developments, the natural habitats of the spotted owls have been greatly affected.
Thankfully, there are still some areas such as the Muir Woods National Park that are well preserved and protected from these logging and urban development activities. At the Muir Woods national park, the Northern Spotted Owl has found a home but it is still not out of danger. For in this same place it calls home lurks another type of owl that is much bigger and aggressive – the Barred Owl. It is not a native owl species in California. The Barred Owl is native to Canada and the eastern United States. Aside from the loss of habitat, this owl species is also a major cause for the decline in numbers of the native Northern Spotted Owl.
