There is a lack of information about species diversity making it difficult to determine population sizes and abundances. During my most recent experiences working at Siuslaw National Forest I had to present a report about “Records of Waterfowls species at Siuslaw National Forest”, and I realized that the lack of data about historical presence and species ecology at certain areas has hampered appropriate management of endangered species. The state of Oregon has a large diversity of birds; specifically, Siuslaw National Forest, it is inhabited by unique native wildlife species of birds and mammals. Birds are the most abundant and conspicuous animals with a historical record of approximately more than 100 species of waterfowls birds. However, taxonomic arrangements and seasonality differences, probably changed species populations numbers.
Something that I learned this week is that archaeological records found more than 8000 years ago the indigenous people that lived around Siuslaw National Forest utilized waterfowl and plover like shorebirds. This reflects the great abundance of waterfowl species at Siuslaw National Forest since historic periods. In the mid 19th century when American-European settlers arrived; timbering, hunting and the alteration of habitat reduced bird populations considerably, endangering and reducing the population of sensitive species. For example, the western snowy plover as a result of their habitat degradation during the 19th century, at the end of the 20th century there were less than 90 resident adults at the Oregon coast. Fortunately, conservation efforts during the past years has increased the population of resident adult snowy plovers to 518.
