President of Sustainable Ecosystems

Tsunami Reef Action Fund
Founder and President of Sustainable
Ecosystems Institute (SEI), Dr. Brosnan is passionate about science
and the oceans. She is a scientist on the front lines, as a strong
advocate for the use of science in ecological decisions, and as a
catalyst for scientists to participate in the global forum. She founded
SEI as the conduit for scientists to outreach to all stakeholders
and to help find science-based solutions to ecological problems. She
believes strongly that scientists must fulfill a new social contract,
and assume a greater leadership role in conservation and natural resource
issues.

The Value of a Wetland System
A few days ago a friend of mine said. “How
do you think I should vote on the Valley Floor?” I can’t
tell you how to vote. But I can share a perspective and urge you to
carefully evaluate the environmental consequences because they directly
impact lives.
In 2001 we at SEI conducted a biological survey
of the Telluride area. Scientists were excited by what they found.
They concluded that the Valley Floor is a unique ecosystem in Southern
Colorado. In spite of human activities, it has retained biological
integrity. Its wetlands and riparian areas provide important habitats
and resources. At least five new moth species and a new genus were
discovered, as well as several new county records for moths, butterflies,
and other invertebrates. This was important news for science and for
the community. Scientists made several recommendations and urged an
integrative and cooperative approach to planning and resolving resource
conflicts that maintained a strong focus the integrity of the ecosystem.
I’d like to share with you another consideration:
For the past year, I’ve traveled through the
tsunami ravaged towns of SE Asia, and lately I’ve visited the
hurricane damaged Gulf Coast of the US. My mission is to assess the
consequences of the ecological damage to people’s lives and
their ability to recover from disaster. It’s a heartbreaking
job. As a scientist, I’ve learned several tough lessons that
apply everywhere including Telluride:- Intact and healthy ecosystems
save lives, property, and economies. We are tied to our environment
and when we damage it we leave ourselves and our communities weakened
and vulnerable.
In SE Asia and the US Gulf States, healthy reefs
and wetlands broke the force of the waves, lessened storm surge, and
minimized flooding. Where ecosystems were fragmented and damaged,
the loss of life and property was greater. This is scientific fact.
In Sri Lanka I stood in a place where the reefs had been destroyed
for use in construction. It was here that a 30 foot tsunami swept
a mile and a half inland and killed 1,700 people on a train. Nothing
remained. Yet a mile down the road where the coast was protected as
a reserve, the tsunami was only 8 foot tall. No lives were lost, and
little property was damaged. Why was there such a difference? Scientists
have confirmed that the intact reefs in the reserve broke the force
of the waves and protected the land. Sadly, the train full of people
was parked next to a damaged ecosystem that could not buffer the wave,
and so thousands perished. In Louisiana, I flew over the coast and
saw how the loss of wetlands contributed to hurricane damage, and
how the state’s recovery is made harder by this loss. Louisiana
has lost 19,000 sq miles of wetlands since 1930 and loses about 24
sq miles of wetlands a year. Yet a mere 2.7 sq miles of wetlands can
reduce storm surge by a foot. Wetlands provide several important ecosystem
services to communities as well as flood protection. A single acre
of wetland, saturated to a depth of one foot, retains about 330,000
gallons of water, which is enough water to flood 13 average-sized
homes thigh-deep. The loss of wetlands is now recognized as a threat
to our own safety and way of life. Many communities scrambling to
restore them are finding that the restoration costs are higher than
maintaining them in the first place- over $33 million to restore one
wetland in Aceh Indonesia alone. In Asia with its monsoons and in
the US Gulf States with the rapidly approaching hurricane season,
communities are recognizing the urgency of restoring their ecosystems,
but sadly now they have too much to do.
Did people and governments set out to deliberately
make themselves and their livelihoods more vulnerable? Of course not.
When a decision was made to carve a canal through a marsh in Louisiana
it surely didn’t seem like major compromise at the time. Many
of us might have agreed with the decision. But when that canal funneled
the storm surge through levees and into homes, leaving whole neighborhoods
uninhabitable, and an economy in tatters, then the true cost became
apparent. “The ecosystem has been fragmented and is on the verge
of collapse.” local scientists and managers kept repeating to
me in Louisiana. I believe them. The south is a hurricane coast and
for hundreds of years the marshes and wetlands protected communities
against storms, but they can’t do this effectively any longer.
It is easy for us to assume that we are immune to
these disasters and their consequences, and to confidently assure
ourselves that Telluride isn’t Asia, or Louisiana. But last
March a colleague from Louisiana talked with me about the poor environmental
approach of Asian communities that suffered more because they had
damaged their marshes and coasts. We never thought it would happen
here. Today her family are hurricane refugees. Telluride and New Orleans
are alike. Both places are facing hard decisions for their future,
and these decisions involve the environment. Both places attract people
who love nature, heritage, and the outdoors. The mountains and high
elevation wetlands of Telluride and the bayous of Louisiana contribute
greatly to their respective economies and quality of life. They are
worth our attention.
When it comes to the Valley Floor, I can only ask
you to look hard at whether you value its services and urge you to
adequately protect it as an intact ecosystem that can provide the
necessary services to the community. Habitat loss, fragmentation,
and the disruption of ecosystem services come with a huge personal
and economic price tag. Ignoring environmental consequences leaves
us as vulnerable to our local events as the town in Sri Lanka that
lost everything. And if that seems far fetched today in Colorado,
remember that less than a year ago it seemed just as far fetched to
me and to that biologist from Louisiana, who this season couldn’t
go home for Christmas.
