Mitigation means to alleviate in force or intensity. Examples include:


■ Making    sure    that    the forest-derived  products    you buy are made    from
100% recycled materials
■ Buying from companies that have a commitment to reducing deforestation
through forest-friendly policies
■ Making sure that, if you are buying products made from virgin forests,
they bear a seal of sustainable forestry certification

PRESERVATION


Preservation means to keep. An example is:


■ Land  trusts  are private,    nonprofit   organizations   that    actively    work    to
conserve land by undertaking or assisting in land or conservation
acquisition, or by stewardship of such land. An example is the Land Trust
Alliance.

REMEDIATION


Remediation means the act or process of correcting a fault or deficiency.
Examples include:


■ Cleanup   from    the 1989    Exxon   Valdez  Alaskan oil spill
■ Cleanup from the 2010 Deepwater Horizon oil spill, which affected the
Gulf of Mexico and the Gulf Coast of the United States

RESTORATION


Restoration is returning something to its former good condition. Ecosystem
restoration involves management actions designed to facilitate the recovery or
reestablishment of native ecosystems. A central premise of ecological restoration
is that restoration of natural systems to conditions consistent with their
evolutionary environments will prevent their further degradation while
simultaneously conserving their native plants and animals. Examples include:


■ Removing  a   dam,    which   will    allow   the return  of  native  fish    to  a   river
■ Removing a harmful, invasive species from a riparian environment

U.S. Forest Service


Forests account for about a third of the land in the United States, the largest of
any land use category. Out of the 747 million acres of U.S. forest land, two-
thirds (500 million acres) are nonfederal.
The Forest Service was established in 1905 as an agency of the U.S. Department
