Oregonís forests are among the most diverse, productive,
and magnificent in the entire world. They range from the dry, scenic juniper and pine forests
east of the Cascades to the wet, majestic old-growth Douglas-fir forests west of the Cascades;
they blanket most of western Oregon and all the mountains of central and eastern Oregon.
Although most of our forests are dominated by needle-leaved conifers, many species of hardwoods
play important ecological roles. Many of the tree species that grow in our forests have their
largest and oldest members here.
Although the percentage of Oregon occupied by forests hasnít
changed much in the past 200 years, the structure, composition, and distribution of our forests
have changed dramatically. Most forests of the early 1800ís have been removed by fire, logging,
and other disturbances--replaced with native trees but in different mixes than were present
originally. Some old-growth forests remain, mostly in remote parts of public lands. Many valley
forests have been lost to agricultural and urban development, although many communities now try
to preserve remaining stands. Fire suppression that has accompanied settlement has also created
many changes, described in the following sections.
Given such change over time, much of modern forestry is directed
at maintaining the health, diversity, and productivity of Oregonís forests while producing the
wood, water, wildlife, and recreation that society demands.
