Oregon has one of the most diverse landscapes of any state in the US. It is well known for its tall, dense forests and its accessible, scenic Pacific coastline. The Willamette Valley is very fertile and, coupled with Oregon's famous rain, gives the state a wealth of agricultural products, including cattle, dairy products, potatoes, peppermint, and apples and other fruits. Oregon is also one of four major world hazelnut growing regions, and produces 95% of the domestic hazelnuts in the United States. Vast forests have historically made Oregon one of the nation's major timber production and logging states, but forest fires (such as the Tillamook Burn), over-harvesting, and lawsuits over the proper management of the extensive federal forest holdings have reduced the amount of timber produced.
