New map data presentations released this month by the Oregon Department of Forestry (ODF) tell the story of how the state’s forest economics, conservation laws, insect or disease damage and wildfire impacts on forests have shaped Oregon during the past few decades.
Seven presentations have been added to the on-line Oregon Forest Atlas [2010 Edition] on the Oregon Department of Forestry web site. The new presentations include:
  • Declines in the Number of Oregon Forest Product Mills, 1980-2010
  • Forest History: Oregon’s North Pacific Coast, 1850-1940
  • Major Insect and Disease Outbreaks on Oregon Forestland, 1986-2009
  • Oregon Coast Range Forestlands: Swiss Needlecast Detection, 1996-2010
  • Oregon Congressionally Withdrawn Forestlands, 1960-2010
  • Oregon Forestland: Severity of Large Wildfires, 1984-2008
  • Sudden Oak Death Impacts on Oregon’s South Coast Forests, 2001-2009
The Oregon Forest Atlas [2010 Edition] project was released last year by ODF as a way to visualize current conditions in Oregon’s forests statewide.  With this week’s release, the atlas  now shows how some key forest trends have shaped the past and future of a state where one-half of the land is forest: 30.5 million acres, making Oregon the second-most forested state by acreage in the country (behind Alaska).  
The map presentations form an ideal education tool, either for personal interest and awareness about Oregon forests or for more in depth studies such as school science projects, community presentations, supporting information for conservation projects in local communities or technical data for public discussions about managing forest ecosystems and habitats.

Maps developed for the Oregon Forest Atlas [2010 Edition] use Geographic Information Systems (GIS) data obtained from several sources, including the U.S. Forest Service’s Pacific Northwest Research Station, Oregon State University and the Oregon Department of Forestry. The Forest Atlas was created by ODF as a public education product of the Statewide Forest Assessment and Resource Strategy, which was commissioned to identify Oregon’s current forest resources, develop a strategy for managing forests that are identified as priority areas in the state, and report on the effectiveness of how federal resources were used.
Data contained within the Oregon Forest Atlas maps do come with limitations, including some data models relying on site information at least one year old and even in instances where satellite imagery is used, maps do not necessarily reflect conditions at a fine-detail level. Forest Atlas maps are not intended for legal, engineering or surveying purposes.
The Oregon Department of Forestry provides a diverse range of services to Oregon’s public, including regulations providing natural resource protection on 12 million acres of private and state-owned forest, management of 818,000 acres of State Forests and fire protection on 15.8 million acres of forest land, most of it privately owned.
2011 marks both the 100th anniversary of the Oregon Department of Forestry and the International Year of Forests recognized by the United Nations.
