Where
We Find Ourselves Today
Our
country is playing a huge game of ecological roulette with the Nation’s resources.
Until our policies get tougher, mostly luck determines whether the new species
that arrive in the United States are useful, benign, or invasive – like the
zebra mussel and northern snakehead fish. The two bills we are considering today – H.R. 5396
and H.R. 5395 – are important steps toward that stronger policy.
In the 1990’s, scientists and policymakers developed
a much greater understanding of invasive species. We discovered, for example,
that the most
damaging single species easily cost us more than ten million dollars per year.
Also, we learned that invasive species are the main contributor to the listing
of about one-half of the Nation’s threatened and endangered native
species. Now a clear understanding
exists that the spread of invasive species is one of the most serious
environmental threats before us. We face a threat that is already changing the
face of the planet.
Yet
changes in federal policy have not kept pace with our new understanding of the
issue. An exception is the area we’re discussing today. With legislation first
passed in 1990, revised in 1996, and now being considered again, Congress has
sought to respond and adapt to this new reality for more than a decade. Yet we
all acknowledge that the previous legislation – and federal agencies’
implementation of it – has provided less help than we hoped. For instance,
invasive species have continued to enter the Great Lakes via the ballast water
of ships despite mandatory efforts to prevent it. Just last Friday, scientists predicted that
22 additional fish species from the Caspian and Black Seas could reach the
Great Lakes via the ballast water of ships – and spread quickly.[1]
They predicted that at least five of these species would become invasive.
The two bills before us today are not Republican or
Democratic bills. Instead, they are the product of a bipartisan effort. We want
to acknowledge
the hard work of many members of Congress and their staffs. In particular, we
would like to thank Mr. Gilchrest, Mr. Ehlers, and their staffs – as well as
the staff of the Northeast Midwest Institute – for their roles in preparing
these bills. Nor are these environmental
bills or industry bills. Their content instead shows the continuing,
good faith efforts of a broad group of stakeholders, as well as the compromises
worked out among them.
The Union of Concerned Scientists is pleased to endorse these bills. Early in 2002, we laid out a number of priorities that we felt would help the National Invasive Species Act protect the United States better – both environmentally and economically. The current bills are consistent with a significant portion of our priorities.
We are especially pleased that certain weaknesses in the 1996 law are being corrected. For example, it is crucial that this legislation, and its most stringent provisions, apply:
We also
strongly support those elements of the legislation that address the full range
of pathways by which we introduce and spread harmful aquatic organisms. Thus,
we give our strong support to a number of specific provisions in these bills:
·
identifying the highest risk pathways for introductions and the rapid
development and deployment of methods to limit them;
·
establishment of a monitoring program to detect and track new invasive
species;
·
ensuring that we have the means, such as contingency plans and specially
trained teams, to respond quickly to these newcomers;
·
and taking a modest step toward more careful assessment of the
potential invasiveness of species proposed for intentional introduction before
they are imported.
Each
is essential if we are to make progress on this issue. And each must be backed
by targeted research – which H.R. 5395 provides.
In
addition, we look forward, under H.R.5396 to much-needed annual updates of the
species listed under the Lacey Act and the Plant Protection Act. It is helpful
to the States that additional elements can be included in their aquatic
invasive species management plants. It is appropriate that matching funds be
available for implementing these plans and that higher levels of funding be
authorized. Also we anticipate the time when federal agencies will more
strictly limit their own introductions. The lists of potential invaders will
help all jurisdictions to be alert and better prepared.
Of
course, since 1990, this legislation has been intended to be our best defense
against further unintentional introductions of invasive species in the ballast
water of ships. Unfortunately, experience has shown us that ballast water
exchange is not effective. The time has come to move away from a primary
reliance on ballast water exchange. Ballast water treatment should be our goal.
We should be moving in that direction boldly, with immediate interim standards
paving the way for more ambitious and stronger permanent ones.
We
are deeply disappointed that the U.S. Coast Guard continues to delay
development of such standards. In 1993, the congressional Office of Technology
Assessment determined how quickly the Coast Guard, as well as the new federal
Aquatic Nuisance Species Task Force, was completing the tasks Congress assigned
to them in the 1990 law. The Coast Guard’s record was stellar. It issued
guidelines, technical assistance, and regulations early or, at most, just a few
months past the law’s deadlines.[4]
It is our hope that the Coast Guard can be stirred to replicate the urgency and
responsiveness the agency showed then.
We
appreciate many of the elements of H.R. 5395, The Aquatic Invasive Species
Research Act, too. It aims to make the collection of information and its
analysis more comprehensive. The research laid out in this bill also advances
the state of scientific knowledge, e.g, on different
ecosystems’ vulnerability to invasion. The availability of scholarships for
taxonomists will be helpful, too. As people become more aware of the harm
caused by invasive species, especially to human health, the need will increase
for environmentally sound tools for detecting, preventing, controlling, and
eradicating aquatic invasive species will increase. It is helpful that both of
these acts encourage their development.
It
is also helpful that H.R. 5395 stipulates that certain research protocols,
contracts for ecological and pathway research, and recommendations for
restricting planned imports nonnative aquatic organisms will be subject to peer
review. In the past, the technical merits of some federal efforts have been
weak.[5]
Peer review, by independent experts with no financial interest in the outcome
of a decision should be a standard supplement to agencies’ requests for federal
comments in highly technical areas. We believe the requirement for peer review
should apply to many of the elements in H.R. 5395 as well. In particular,
attempts to develop screening methods need to have the input and review of
academic experts and others outside the federal government. To help you
consider the research we will need over a longer term, I have attached the
recommendations of three expert groups of scientists.[6]
A
Larger Vision: Where We Need to Keep Working
From
discussions of voluntary measures in the nursery and aquarium industries to the
willingness of shippers to change their ballasting practices – all trends point
in one direction. Governments, industries, and individuals are taking greater
care to limit their movements of damaging species around the world. We are
certain that, eventually, all intentionally introduced organisms will be
effectively screened for invasiveness before import – with the most invasive or
potentially invasive kept out. We would like to see that time come as soon as
possible. And we would like it to be with the least possible number of
exemptions for organisms now in trade. This last includes aquatic species in
the live food trade – which brought the northern snakehead to Maryland this
summer.
Also,
we hope that federal standards for screening or for treating ballast water do
not represent “a race to the bottom.” We need federal standards that are at
least consistent with the most
comprehensive approaches taken at the state level.
While
we are not generally sympathetic to calls for delay, neither are we advocates
for unfunded congressional mandates. Eventually we must have formal provisions
for generating sufficient revenue to ensure adequate funding not just for the
new work we are discussing today, but also to undertake more ambitious efforts,
e.g., to screen organisms prior to import.
Zebra
mussels, nutria, and the seaweed caulerpa have not
halted their spread for our elections. Therefore we hope that either this
Congress passes these bills now or that the new Congress will pass them in its
first 100 days. We look forward to helping you make that happen.
A
Final Parable
I first testified regarding invasive species in 1993
for what was then the House Merchant Marine and Fisheries Committee. I
represented a congressional research agency at the time and the Subcommittee
specifically asked me to address the risks posed by the proposed import of the
Asian black carp.[7]
It was clear from my quick reading of the scientific literature that this
species posed a substantial risk to the nation’s aquatic resources. Addition to
the Lacey Act’s list of prohibited species would have been a logical step. That
was 1993. This fish is still not listed on the Lacey Act. On September 30,
2002, almost exactly nine years later, the official public comment period ended
for the Fish and Wildlife Service’s proposal to make this fish subject to the
Lacey Act. Is there anyone here who believes that ten years is a timely or
adequate response to the dangers posed by a particular invasive species? I ask
you to remember this example as we consider how quickly H.R. 5396 and H.R. 5365
should turn the wheels of government.
