The Northern Spotted Owl Research

I decided to study Northern Spotted Owl at Keystone Lab. Many factors influence this kind of life. The northern owl is said to be in an old forest in northern California, Oregon, Washington state, a narrow area of ​​British Columbia and Canada. Owls have lived in these areas for hundreds of years, but were discovered for the first time in the early 1900s. We all know that owls (Strix occidentalis caurina) are important species, but it is also known as an indicator species of old growing forests.

Owl owls can only live in ancient growth environments; it is considered "an indicator species": the health condition of the owl owls shows the health of the old forest ecosystem. Due to the lack of food, older owls need older growths of over 3,000 acres to survive. Northern Spotted Owl is in the cool and damp woods of the Pacific Northwest. The second roundtable that President Clinton assisted in the establishment aimed to define the scientific point of view. Where are we now? Where do you want to go? John Gordon of Yale University says: "Ecosystem management gives you knowledge about the entire forest and one or more species are revealed at one time." New forestry techniques are applied to the habitats of the discovered owls. Our radio tracking data shows that owls continue to use Frost Meadows units after harvest. "

On June 26, 1990, Northern Spotted Owls was designated to be threatened throughout the range. The discovered owl lives in a North American forest. Because their habitat is destroyed by logging, they are on the verge of extinction. Forest Service owl expert Erica Fosman said that if this trend continues, efforts to protect the endangered owl in the past decade are impossible. According to the US Endangered Species Protection Act, Fosman's research in the 1970s and 1980s discovered owls as an endangered species 10 years ago and caused intense controversy between environmentalists and loggers. In 1993, President Bill Clinton's administration reduced the scale of logging on the federal government's land. This was less than a quarter of what was allowed in the 1980s. Since then, the decline in the number of owl populations has been significantly slowed down, estimated to be 4% annually.
