Oregon white oaks, also known as Garry oaks or savannah oaks, are Washington's only native oaks. DuPont, Washington, has a number of landmark trees that are between 100 and 250 years old.
Winter oak woodland
Two hundred years ago – when many of DuPont’s landmark trees were young saplings – prairies and oak woodlands covered much of the South Puget Sound area.
Today only 3 percent of these woodlands remain.
