SUBJECT
Growing Problem of Invasive Species
INTRODUCTION
On behalf of the National Association of State
Foresters, I am pleased that Chairman Gilchrest and Chairman Radanovich
have asked us to testify on the growing problem of invasive species.
NASF is a non-profit organization that represents the directors of the
state forestry agencies from all fifty states, eight U.S. territories,
and the District of Columbia. State Foresters manage and protect state
and private forests across the U.S., which together encompass two-thirds
of the nation’s forests.
I am representing NASF in my role as Chairman of
the Forest Health Protection Committee. Addressing the spread of
invasive species is an objective of high priority for my committee, as
invasive species—weeds, insects, pathogens, animals, etc.—are a growing
concern among foresters and other natural resource professionals. I
hope you find our comments instructive as you consider possible
Congressional legislation or other federal actions to help get ahead of
this ubiquitous problem.
In this testimony, I will address the topics you
raised in your invitation to testify: (1) the scope of the invasive
species problem; (2) current efforts to control or eradicate invasive
species; (3) the adequacy of existing statutory authority to stop the
expansion of invasives; and (4) our recommendations on how to stop the
problem.
CLARIFICATION
Before I discuss the topics you raised, I would
like to offer a point of clarification about what constitutes an
invasive species.
As natural resource managers, our use of the term
“invasive” is often synonymous with “exotic” or “non-native”—species that
presumably originate from distant corners of the world and are transported
here. Many exotic insects, plants, and animals have become very
destructive after entering the U.S. However, it is important to remember
that several species indigenous to the U.S. are equally harmful to our
environment and economy, as well as those of other countries. In other
words, not all invasive species are exotic, and the U.S. is both a
recipient and a contributor to the problem.
The red oak borer is a case in point. Populations of
the native insects recently have skyrocketed in the Ozark Highlands of
Arkansas, Missouri, and Oklahoma. Aging trees and overcrowded conditions
due to the long term suppression of fires and the lack of active forest
management, exasperated by naturally thin soils, heat waves, and droughts,
have helped to create an environment for the red oak borer to thrive. In
the Ozark Highlands today, as much as one million acres of dead or dying
oaks pose severe wildfire hazards to communities, drinking water supplies,
and the health of forests.
Scope of
Invasive Species Problem
As the Subcomittees are acutely aware, the problem of
invasive species is large and growing. A recent report
on the status of invasive species efforts published by the Congressional
Research Service (CRS) estimates that 30,000 non-native species exist
across all the states and US territories. CRS also estimates that
economic losses due to invasives are estimated to exceed $123 billion
annually in the U.S. The impact of invasives are tremendous, degrading
the environment nationwide and affecting a range of industries including
transportation, agriculture, recreation, fisheries, and others.
Forestry is no exception. From coast to coast and
north to south, forests are suffering from the damaging effects of a long
list of invasives: Asian longhorned beetle, gypsy moth, hemlock and balsam
wooly adelgid, and other damaging insects; kudzu, privet, callery pear,
and other plants; and sudden oak death, apparently caused by a pathogen.
Insects, diseases, and noxious weeds especially plague forests across the
nation, and aggressive efforts must be taken to keep them under control.
As an example, the wooly
adelgids are wreaking havoc on forestlands on both the east and west
coasts. The balsam wooly adelgid, a tiny sucking insect that was
introduced (probably from Europe) to the east coast of North America about
1900, was first detected on the west coast in about 1930. It infests all
true firs (trees in the genus Abies), but is most damaging to North
American species such as Fraser fir and balsam fir in the east, and
subalpine fir and Pacific silver fir in the west. In some sites,
susceptible species have been wiped out. The range of subalpine fir will
probably be reduced to just the highest elevations in its current range.
When this insect reaches the extensive subalpine fir forests of the Rocky
Mountains, it will likely dramatically change those landscapes.
In the east, the hemlock woolly adelgid is destroying
streamside forests throughout the mid-Atlantic and Appalachian region,
threatening water quality and sensitive aquatic species and posing a
potential threat to valuable commercial timber lands in northern New
England.
State Foresters, private landowners, and our partners
are increasingly spending our limited money and time on controlling
outbreaks of these and other invasive forest pests.
Efforts to
Control or Eradicate
State Foresters are currently involved with several
efforts to control or eradicate invasives. In this testimony, I would
like to mention three of the most promising efforts underway: (1) National
Invasive Species Council; (2) USDA Forest Service programs; and (3) 2002
Farm Bill Programs.
National Invasive Species Council
One of the most important steps made in recent years
toward enhancing the capacity to control or eradicate invasive species was
the creation of the National Invasive Species Council. Established
through an executive order signed by President Clinton in 1999, the
Council is an interagency committee gathered to develop recommendations
for international cooperation, promote a network to document and monitor
invasive species impacts, and encourage development of an information
sharing system on invasives.
In January of 2001, the National Invasive Species
Council released Meeting the Invasive Species Challenge,
a national invasive species management plan that represents the first
major federal attempt to coordinate invasive species actions across
government agencies. The plan calls for several areas of emphasis for
invasive species management that should be part of any comprehensive
effort to address the problem: (1) prevention; (2) early detection and
rapid response; and (3) control and management. The plan includes the
recommendation that draft legislation be developed to authorize matching
funds for states to manage invasive species and to control invasives on
state or private lands with the consent of the owner, a prospect that NASF
highly endorses and hopes the Subcommittees will consider.
USDA Forest Service Program
The USDA Forest Service State and Private Forestry
(S&PF) Deputy Area has several programs that assist landowners with
invasive species management, especially those within the Forest Health
Protection unit. As authorized by the Cooperative Forestry Assistance Act
of 1978, and amended in 1990, the State Foresters deliver S&PF programs to
provide cost-share funding and technical assistance to private
landowners. The broad authority of the Cooperative Forestry Assistance
Act can provide the infrastructure to jumpstart any new invasive species
management programs that the Subcommittees may propose.
Through its three program areas (Federal Lands,
Cooperative Lands, and the proposed Emerging Pest and Pathogen program),
Forest Health Protection provides an important foundation for managing
insect and disease outbreaks by reporting on forest health trends,
surveying and monitoring, supporting the delivery of technical assistance,
and providing prevention and suppression activities. In our FY 04 budget
recommendations,
NASF encouraged Congress to include targeted funding under Forest Health
Protection for the President’s Healthy Forests Initiative to address the
southern pine beetle infestation, which is reaching epidemic proportions.
Also in FY 04, the Forest Stewardship Program has some funding for
competitive grants for the purpose of improving forest health by treating
invasive insects, diseases, and plants on state and private forestlands.
Invasive species management is also important to the
Forest Service’s other Deputy Areas, including the National Forest System
and Research and Development. These well-established programs need
sufficient funding to effectively address invasive species over the long
term. Again I would point you to NASF’s House Appropriations testimony
for our FY 04 budget recommendations.
The Forest Service also works closely with the Animal
and Plant Health Inspection Service (APHIS) to detect and rapidly respond
to exotic pests that threaten agricultural crops and natural habitats. A
1997 General Accounting Office report
suggests that despite increases in funding, staffing, and the use of
technology, APHIS is having difficulty keeping up with the increased
inspections accompanying increases in trade.
2002 Farm Bill Programs
The 2002 Farm Bill made substantial gains for
invasive species management for forestry through authorizing the Forest
Land Enhancement Program and the Community and Private Lands Fire
Assistance program.
Replacing the Stewardship Incentives Program and
Forestry Incentives Program, the Forest Land Enhancement Program (FLEP)
provides education, technical assistance, and cost-share funding to
private forest landowners. FLEP is designed to keep priorities flexible
at the state level as much as possible, with priorities determined with
input by State Forest Stewardship Committees. The program can be used for
a variety of forestry assistance purposes, including the control,
detection, monitoring, and prevention of the spread of invasive species
and pests, as well as the restoration of ecosystems altered by invasives.
The State Foresters hold great promise for FLEP in terms of landowner
assistance, but it must be recognized that invasive species management is
only one of many activities that the program supports.
The Community and Private Lands Fire Assistance
program, authorized but not funded in the 2002 Farm Bill, will also
address the need to control noxious weeds and other invasive species
within areas burned by wildfire. Without controlling noxious weeds that
invade recently burned lands, areas damaged by fire can become significant
sources for the further dispersal of weeds to other areas.
adequacy
OF EXISTING STATUTORY AUTHORITY
Although numerous existing federal statutes or
authorities address invasive species, there remain large gaps in law. The
publication, Meeting the Invasive Species Challenge, described
above, includes a partial list of 40 legal authorities of the U.S.
Departments of Agriculture, Commerce, and the Interior, as well as the
Environmental Protection Agency and other federal agencies (see Appendix
3, pp. 62-70). Although work done under these authorities may limit such
introductions, many laws do not directly address invasive species control
and prevention, and those that do generally target one species that has
become problematic. To my knowledge, the U.S. lacks a comprehensive
approach to address invasive species, one that makes use of effective
partnerships between all levels of government in all regions to identify
and quickly respond to threats early (before they become a problem),
effectively control outbreaks when they occur, and restore damaged
ecosystems.
According to the CRS report mentioned earlier,
comprehensive legislation on the treatment of non-native species has never
been enacted, and no single law provides coordination among federal
agencies. The National Invasive Species Council may have made some
headway in regard to coordination, but its management plan also noted the
need to develop legislative proposals to fill gaps in current law.
Meeting the Invasive Species Challenge specifically explains that
current law does not clearly address the prevention of biological invasion
across foreseeable pathways, nor does it provide explicit direction on
management during the critical period between the introduction of a new
non-native species and the time the species becomes established, when
focus must shift from prevention to control.
RECOMMENDATIONS
The development of a comprehensive legislative
package to help State Foresters and other resource managers aggressively
tackle invasive species issues will be key to addressing invasive species
over the long term. I hope you will keep the following principles in mind
as you consider developing any such proposals.
Active Forest Management
Emphasis must be placed on active forest management.
When the problem is compelling and the solution is clear, management needs
to happen as soon as possible. Some research is needed, but the overall
emphasis should be on doing something on the ground where and when the
problems occur.
Early Detection and Rapid Response
The early detection,
control, and prevention of damaging invasive species is critical to the
health of forests on all ownerships. The broad range of sectors that
contribute to the propagation and spread of invasive species hold the
promise for innovative and incentive-driven solutions. Constituents from
these sectors should be at the table in developing solutions.
Existing successful programs may serve as models for
early detection and rapid response. For example, the CRS publication
noted above suggests that the National Interagency Fire Center (NIFC), of
which the State Foresters are a key cooperator, could be a model for
Congress to consider when developing rapid response programs. Efforts to
quickly respond to wildfires face many of the same challenges of haste,
technical needs, and interagency and intergovernmental coordination as do
rapid responses to invasive species outbreaks.
A Pathways Approach
Invasive species management should focus on the
variety of pathways by which invasive species enter the U.S. We need to
identify and build capacity to respond, such as through early detection at
ports or other shipping facilities. For example, through early detection
measures targeting solid wood packing materials at ports, we might have
avoided the spread of the Asian longhorned beetle to the U.S.
Long-term Investment
Long term programs with ongoing funding are needed if
we are to successfully control, mitigate, and eradicate harmful nonnative
species on public and private lands. This is due to both the extended
survival or dormancy of seeds and the continuous threat of new species
introductions from overseas.
State/Federal Partnerships
Effective partnerships between various levels of
government, especially between state and federal agencies, will be
critical to promptly dealing with invasive species issues. In guidelines
recently adopted by the Invasive Species Advisory Committee, an advisory
committee that supports the National Invasive Species Council, the group
makes clear that effective partnerships among all levels of government are
important first steps to building our capacity to control and eradicate
invasive species across the country. The document, Guidelines and
Strategies for a Successful State Federal/State Partnership to Combat
Invasive Species, was adopted by the committee during its most recent
meeting.
The advisory committee will be recommending that the
Council use the following guidelines when developing administrative
proposals or commenting on Congressional legislation for partnerships
between federal and state agencies:
Ø
Incentive-driven with the voluntary cooperation of the
private sector
Ø
Flexible enough to address agency and community needs at the
local level
Ø
Support the development of state-level invasive species
management plans
Ø
Rapidly respond to priority invasive species that could
spread
Ø
Share successful invasive species management techniques
among states and regions
Ø
Increase public support and understanding of invasive
species issues
CONCLUSION
Invasive species management on all lands will be
strengthened through integrated, results-oriented work. Where program
areas overlap, limited federal dollars can be spent most effectively on
integrating new and existing programs, and making use of the experts who
are already involved with established authorities. By bolstering existing
programs as much as developing new ones, a comprehensive package can
provide an ideal opportunity to effectively address invasive species in a
multi-ownership landscape.
NASF looks forward to the opportunity to work with
the Subcommittees to develop and carry out effective, comprehensive
programs to address the spread and control of invasive species. We are
willing to help draft legislation to address these issues.
I appreciate the opportunity to provide testimony and
answer your questions today.
