Tensas
River National Wildlife Refuge, Tallulah, Louisiana
Tensas
River NWR features prominently in the U.S. Fish and Wildlife Service’s
reforestation efforts to help increase the benefits of terrestrial carbon
sequestration . Since 1999, more than 4,000 acres of refuge land, once
cleared for agriculture, has been planted with native species of bottomland
hardwoods. The original forest on this acreage had been clear-cut many
decades prior to the refuge’s establishment in 1980.
The refuge is located in
the upper basin of the Tensas River in northeastern Louisiana. It consists,
today, of 2,514 acres of open water and wetlands, 54,808 acres of bottomland
hardwood forest, 4,000 acres of newly-planted woodlands, and 3,000 acres
of cooperatively farmed crop lands.
Service partners, who have
contributed towards these reforestation projects and the acquisition
of additional land , include power utilities, Entergy Corporation and
Dynegy Inc, Texaco, Future Forest and Trust for Public Land. Donations
from contributors went into purchasing 1.25 million trees (approximately
302 trees per acre) and funding contract labor to plant the trees.
The trees species planted
included: Nuttall oak, water oak, willow oak, overcup oak, cherrybark
oak, sweet pecan, green ash, sweetgum, bald cypress, persimmon, red
maple, bitter pecan, Shumard oak, red mulberry, and American sycamore.
For their first 3-5 years,
the Service routinely monitors the young saplings. During this time
they are susceptible to drought and damage from insect pests. As the
trees begin to reach maturity they soon provide valuable habitat for
the threatened Louisiana black bear, many species of neotropical migratory
songbirds, white-tailed deer, and countless other woodland dwellers.
In
just 20 years, barring fire, flood, or other disaster, these 4,000 acres
of bottomland hardwood trees will have removed an estimated 3,500 short
tons of carbon dioxide from the atmosphere, thereby helping to reduce
the potential for global warming. In addition to providing valuable
wildlife habitat and overall bio-diversity enhancement, other benefits
include reduced soil erosion and and contamination from animal waste,
applied pesticides and other toxic chemicals.

Catahoula
National Wildlife Refuge
Rhinehart, Louisiana
Catahoula
NWR (http://catahoula.fws.gov/)
was established, October 28, 1958, as an inviolate sanctuary for waterfowl
and for wildlife conservation. The refuge is located in east central
Louisiana, 12 miles east of Jena. The 6,671-acre Headquarters Unit is
located along nine miles of the northeast shore of Catahoula Lake, a
26,000-acre natural wetland, renowned for its large concentrations of
migratory waterfowl. It was designated June 18, 1981 as a wetland of
international importance by the Ramsar Convention.
This Convention on Wetlands,
signed in Ramsar, Iran, in 1971, is an intergovernmental treaty which
provides the framework for national action and international cooperation
regarding the conservation and wise use of wetlands and their resources.
There are presently 140 Contracting Parties to the Convention, with
1374 wetland sites, totaling 121.4 million hectares, designated for
inclusion in the Ramsar List of Wetlands of International Importance.

In
the year 2000, as part of the first carbon sequestration project on
Catahoula NWR, 190 acres were reforested on the refuge’s Willow
Lake Unit, by Environmental Synergy, Inc. (ESI) (http://www.environmental-synergy.com/main.html)
. Two years later, ESI planted another 43 acres on the Unit, bringing
the total to 81,950 seedlings planted on 233 acres. This land had been
originally cleared for farming in the 1970s. The service acquired these
marginal agricultural lands in 1996.
In the spring of 2001, The
Conservation Fund (TCF) (http:conservationfund.org/)
purchased the 18,372-acre, Bushley Bayou Unit – land that had
also been cleared for agriculture during the 1960s and 1970s. The Fund
then turned 8,115 acres over to the Service for the Catahoula refuge.
The remaining 10,257 acres it sold to American Electric Power (AEP)
( http://www.aep.com/environmental/performance/emissionsassessment/default.htm
)for use in a terrestrial carbon sequestration project. AEP entered
into a management agreement with the Service to manage this land as
part of the refuge. This Unit is located eight miles west of Jonesville
and its acquisition was made possible through a partnership agreement
between the Service, The Conservation Fund, and American Electric Power.
The partnership was formed
to bring together private industry, a conservation organization, and
the federal government for the purpose of habitat protection and restoration.
American Electric Power was willing to acquire cleared, unproductive
agricultural fields and lands and reforest them for future potential
carbon sequestration credits. The Conservation Fund and the U.S. Fish
and Wildlife Service were interested in restoring this degraded habitat
to provide for wintering waterfowl, migratory birds, and the restoration
and preservation of bottomland hardwood forest.
The reforestation of 9,784
acres of the Bushley Bayou Unit was completed in two phases. Phase one
began in 2001, with 2,492 acres being planted with 748,750 seedlings.
During phase two, AEP planted 5,533 acres on its own land, adjoining
the refuge and on 1,759 acres of Service land – for a total of
7,292 acres planted with 2,229,390 seedlings. In all, the total area
was is planted with 2,978,140 seedlings.
The trees planted in connection
with these reforestation projects on both the Willow Lake and Bushley
Bayou units were all bottomland hardwoods, that are native to the area
and selected to match the soil types and flood tolerance. Most of the
trees were hand planted by crews of 10 to 20 men, but some 1,200 acres
on the Bushley Bayou Unit were machine planted.
Actual species planted were:
willow oak, green ash, baldcypress, Nuttall oak, overcup oak, persimmon,
sweet pecan, water oak, Shumard oak, bitter pecan, American elm, swamp
chestnut oak, water tupelo, sycamore, hackberry, sweetgum, and red maple.
In all, seventeen species of bottomland hardwoods were planted.
In 20 years from now, these
10,000 acres of forest land will have removed approximately 1.142 million
tons of carbon from the atmosphere.
The species expected to
benefit from the completed reforestation projects on the Catahoula refuge
are waterfowl, neotropical migratory songbirds, and resident game species
such as white-tailed deer, fox squirrels, and countless other forest
dwellers.
