Mount Hood National Forest Mature and Old-Growth Forest Maps
An interactive map of the Mount Hood National Forest's mature and old-growth forests.
Northern half of the Forest
Blue = Mature forests 80-120 years of age*
Green = Old-growth forests 120+ years of age*
Southern half of the Forest
Blue = Mature forests 80-120 years of age*
Green = Old-growth forests 120+ years of age*
* There is no exact definition for what constitutes an old-growth or mature forest. For the purpose of mapping the general location of these forests, mature forests are defined as 80-120 years of age, and old-growth as 120 years and older. While these aren't exact numbers, the generalized range helps give an idea of where mature and old-growth forests exist in Oregon. Oregon Wild believes these maps to be the most accurate depiction of mature and old-growth trees for these areas, but its important to note that the data is not perfect. Forest inventories were created using a variety of source data including USFS data.
