Invasive Species
 Non-native
species displace natives
and cause ecological, biological, and
economic losses. In 2002, invasives
cost U.S. taxpayers $137 billion in
damages.
 Most invasive species found in the
U.S. were originally imported for
food, fiber, or as ornamental plants.
Healthy Forests Make
for a Healthy Nation
The Forest Service is looking
forward to its Next Century of
Service, carrying on its mission of
“sustaining the health, diversity,
and productivity of the Nation’s
forests and grasslands to meet
the needs of present and future
generations.”
Invasive Species
The leadership of the Forest Service
determined that nothing short of a
collaborative effort across deputy areas
and in partnership with external
organizations is required for an effective
and proactive strategy against invasive
species.
 This approach is spelled out in the
National Strategy and Implementation
Plan for Invasive Species Management.

Guiding Principles of the National Strategy
1. Science-based prioritization of
invasive species problems.
2. Enhanced collaboration on the
solutions to those problems.
3. An improved system of accountability
that ensures the most efficient use of
limited resources at all levels of the
Forest Service.

Elements of the National Strategy
1.
2.
Prevention – Keep out invasive species.
Early Detection and Rapid Response
– Detect and eradicate invasive species to
stop them from spreading.
3. Control and Management – Apply
integrated control techniques to manage
the problem.
4. Rehabilitation and Restoration –
Heal, minimize, or reverse the harmful
effects from invasive species


Forest Service programs to fight
invasives will focus on:
 Internally - stopping invasive species
from becoming widespread in the
National Forest system
 Externally – supporting stewardship
work on State, Tribal, and private
partner lands

Conclusion
 The
National Strategy and
Implementation Plan for Invasive
Species Management is a significant
milestone in the effort of the Forest
Service to stem the tide of nonnative
invasive species.
 A key to this effort is the two
Environmental Threat Assessment
Centers established in Prineville,
Oregon and Asheville, North Carolina.
