Park Creation Timeline
In 1897 President Grover Cleveland creates the Olympic Forest Reserve.
In 1909 President Theodore Roosevelt designates a portion of the reserve Mount Olympus National Monument, mostly in response to the slaughter of the area elk.
In 1938 President Franklin D. Roosevelt signs legislation creating Olympic National Park, absorbing the national monument. It was nearly named Elk National Park instead.
International Biosphere Reserve status is given to the park by UNESCO (United Nations Educational, Scientific and Cultural Organization).
The park is named a World Heritage Site by UNESCO (United Nations Educational, Scientific and Cultural Organization).
Animals and Plants
Olympic's huge variety of ecosystems leads to a huge variety of wildlife. Mammals includes Roosevelt elk, blacktailed deer, otters, seals, whales, dolphins, marmots, and porpoises.
There are 13 species of frogs, toads, and salamanders. The climate is not ideal for reptiles, but there are 3 snakes and 1 lizard species, none of which are venomous.
There are about 300 species of birds observed in the park.
The ecosystem variety results in over 1,200 types of plants. There are four types of forest alone, including montane, alpine, lowland, and temperate rain forest.
