Furthermore
Volunteers Help Conserve Great Lakes Marshes
by Jon McCracken, Bird Studies Canada
Degradation and loss of marsh habitat continue to threaten the many birds
and amphibians that rely on the Great Lakes ecosystems. However, little
is known about the population trends and specific habitat needs of many
species of marsh-dependent wildlife. Following 2 years of pilot work,
Bird Studies Canada launched the Marsh Monitoring Program across the Great
Lakes Basin in 1995 in partnership with Environment Canada and the U.S.
Environmental Protection Agency. The program’s primary goal is to
monitor populations of marsh birds and amphibians across wetlands in this
unique region by engaging the skills of hundreds of volunteers.
More than 300 volunteers follow a standardized protocol, guided by detailed
written and audio training materials. Surveys are conducted at semicircular
stations of 100-metre radius positioned along routes. Nocturnal surveys
for calling frogs and toads are conducted three times during spring and
early summer. Evening bird surveys are conducted twice during the height
of the breeding season using taped vocalizations to elicit responses from
several secretive species. Participants also describe the habitat features
at their survey stations. An important aspect of the program is its ability
to determine habitat associations of marsh birds.
Based upon the first 7 years of the program, significant declines have
been detected in populations of American coot, common moorhen, sora, black
tern, pied-billed grebe, sedge wren, and even the ubiquitous red-winged
blackbird. Similar declines have occurred for chorus frog and American
toad. Significant increases were detected for common yellowthroat and
mallard. Further analysis reveals that some of these population changes
are attributed, in part, to annual fluctuations in Great Lakes water levels.
Species that show consistent year-to-year declines warrant closer scrutiny
and perhaps immediate conservation attention.
Volunteer-supplied data enable scientific analysis, which is then made
available for assessment purposes and conservation planning. By participating,
program volunteers make significant contributions to management plans
at the local and individual lake-basin scales, and help in the overall
assessment of wetland health across the Great Lakes Basin. Moreover, the
program’s data serve to increase awareness of marsh bird, amphibian,
and wetland habitat conservation issues among scientists, and regulators
and the public.
In keeping with the North American Waterbird Conservation Plan, it is
envisaged that a coordinated marsh bird monitoring program will develop
across North America.
In the meantime, recent program reports and other publications are available
in the Library on Bird Studies Canada’s Web site at www.bsc-eoc.org.

Mangroves: Life on the Edge
by Alfredo Quarto, Mangrove Action Project
“Amphibious rainforests.” “Coastal nurseries.”
“Roots of the sea.” Not bad monikers for an ecosystem once
widely described as a foul-smelling, insect-infested wasteland. Mangrove
forests are increasingly recognized and appreciated as one of Earth’s
most productive and biologically diverse habitats. Given their previous
reputation, however, they also are among the world’s most threatened
habitats from decades of abuse and exploitation.
Thriving in two worlds at once, salt-tolerant mangroves accommodate the
needs of both aquatic and terrestrial wildlife. Their semisubmerged tangle
of roots offers refuge and nursery areas for fish, crabs, shrimp, shellfish,
and other aquatic species. Loosely interwoven branches provide hundreds
of waterfowl, shorebirds, waterbirds, and songbirds with nesting and feeding
sites adjacent to critical water resources. Some Latin American countries
have recorded more than 500 bird species in their mangrove areas, which
likewise host manatees, monkeys, amphibians, and other fauna.
Mangroves supply food, tannins, fuel wood, medicinal ingredients, and
construction materials to coastal communities. They also protect shoreline
property from storm damage and erosion and prevent silt and polluted runoff
from reaching coral reefs and seagrass beds.
Mangrove forests once blanketed coastlines and estuaries throughout tropical
and subtropical Africa, Asia, the Americas, and the Isles of Oceania,
, but now less than half, or approximately 18 million hectares, remain.
Overharvesting for timber and charcoal, urban expansion, pollution, coastal
road construction, industrial development, and large-scale shrimp farming
are culpable, with the latter potentially accounting for up to 30 percent
of current destruction.
The rapidly expanding shrimp-aquaculture industry, largely fueled by
voracious consumer demands in the United States, Canada, Japan, and Europe,
poses one of the gravest threats to the world’s remaining mangrove
forests and the wildlife and communities they support. An estimated 1
million hectares of coastal wetlands, including mangroves, have been cleared
worldwide for conversion to shrimp farms that range from one-half hectare
to hundreds of hectares each. A telling sign of this boom-and-bust industry
is that approximately 250,000 hectares now lie abandoned due to diseased
shrimp and polluted waters. In Latin America, barbed wire and armed guards
posted around shrimp farms prohibit local fishing communities from accessing
the mangrove forests they traditionally used. Also displaced are native
nursery grounds of aquatic species, including shrimp, important to local
economies.
Since 1992, Mangrove Action Project (MAP), an international nongovernmental
organization, has worked with partners worldwide to halt mangrove destruction
and promote sustainable alternatives. Their growing concern is the rapid
proliferation of shrimp farms in Brazil, which houses the world’s
second largest expanse of mangrove forest with over 1 million hectares.
Brazil produced 60,000 tons of farmed shrimp in 2002, exporting 90 percent.
This tonnage will likely more than double by 2005 as shrimp farmers from
other countries continue to leave their beleaguered coasts to start here
anew.
The MAP, therefore, conducted one of its regional “In the Hands
of Fishers” workshops in Brazil in May 2003, bringing together more
than 60 stakeholders from Guatemala, Honduras, Colombia, Ecuador, and
Brazil. All were members of grassroots organizations and fishing communities
and active in the mangrove network known as Red Manglar. Participants
discussed common mangrove conservation concerns, particularly Brazil’s
burgeoning shrimp-aquaculture industry, exchanged information, shared
lessons learned, formed new partnerships, and developed regionally coordinated
projects. The World Conservation Union, Tropical Rainforest Programme
- The Netherlands, and the Interchurch Organization for Development Cooperation
funded the workshop, and MAP and the Brazilian nongovernmental organization
Terramar co-coordinated it with assistance from Red Manglar members.
Just as mangroves are the “roots of the sea,” this expanded
network of partners will continue to strengthen and spread the roots of
the mangrove conservation movement throughout Latin America.

An Agricultural Policy Framework for Canada
by Duncan Morrison, Ducks Unlimited Canada
Today's consumers are asking hard questions—and rightly so—about
food safety and the environment, and they are demanding answers from the
entire agri-food supply chain. How successful we are in meeting and beating
these challenges will, to a large degree, determine our competitive edge
in both domestic and global agri-food marketplaces.
That is why a new vision for the Canadian agriculture and agri-food
industry is so urgently needed. To that end, in June 2002 in Whitehorse,
Yukon Territory, provincial and territorial ministers of agriculture and
I agreed on the principles of an action plan to put Canada first in the
eyes of consumers as the world leader in food safety, innovation, and
environmentally responsible production.
This Agricultural Policy Framework which we are developing has five
key elements: business risk, food safety, environment, sector renewal,
and science and innovation. Together, these elements form an integrated
approach to help the Canadian agri-food industry be front and centre in
the world marketplace.
—The Honorable Lyle Vanclief, Minister of Agriculture and Agri-Food,
at the Moving the Markets Forum, Toronto, Ontario, February 2003.
Since Minister Vanclief's speech, two significant events have transpired
that further impact his message. Front and centre was the Spring 2003
closure of important international borders to Canadian beef. The Canadian
Food Inspection Agency has since concluded the investigation of a single
case of Bovine Spongiform Encephalopathy (BSE), commonly known as “mad
cow disease,” in Alberta. This single case was detected as part
of Canada’s ongoing BSE Surveillance Program and was the cause behind
the border closings. Canada's recovery as a leading provider of the world's
beef supply is slowly moving forward in the wake of this isolated incident.
However, quietly building momentum in the large shadow of the BSE crisis
was the move by an increasing number of Canadian agricultural producers
to work with governments to strengthen their ability to protect the environment.
These producers understand that environmental stewardship is the key to
both long-term sustainability and profitability. Through the APF, new
programs will build on environmental practices to enhance air, water,
and soil quality and biodiversity conservation to improve the ability
for agriculture and the environment to coexist in a way that provides
benefits to both.
Key components of the Environment Element of the APF include Greencover
Canada and Environmental Farm Plans (EFPs). The EFPs, voluntarily prepared
by farm families, will highlight environmental strengths on their farm,
identify areas of environmental concern, and set realistic goals and timetables
to improve environmental conditions. Once completed, the EFPs will then
be supported by Beneficial Management Practices (BMPs), which will target
improvements such as riparian area management, the establishment of shelterbelts,
and grazing management.
Farmers have expressed substantial interest in EFPs and the Greencover
Program. With all provinces signing on to the APF and with several of
those provinces also signing Implementation Agreements, the Government
of Canada is helping Canadian producers take steps to do their part in
protecting the environment.
The Greencover Canada Program is a 5-year, $110 million, Government of
Canada initiative to convert environmentally sensitive land to perennial
cover. One component of Greencover is the conversion of environmentally
sensitive land to perennial cover. Other components focus on critical
areas, shelterbelts, and technical assistance. With the assistance of
organizations such as Ducks Unlimited Canada, Greencover will also allow
producers to improve grassland management practices, protect water quality,
reduce greenhouse gas emissions, and enhance biodiversity and wildlife
habitat. In return for the preapproved conversion of their land, landowners
receive advice and financial incentives from the government to help the
transition.
"Greencover has the potential to improve wildlife habitat on more
than 1 million hectares of land in the next 5 years. If it is well received
by producers, we are hopeful that an even bigger program will be developed
to follow this one," said Dr. Brian Gray, Ducks Unlimited Canada's
director of conservation programs. "We also hope that a BMP for wetland
restoration and conservation will be adopted into the process."

Sustainable Forests, Sustainable Futures
by Darron Collins, World Wildlife Fund
In Peru, the 68 million hectares of forest that carpet the uppermost
reaches of the Amazon basin are some of the most biologically diverse
in the world—a 1-hectare plot can harbor over 400 species of trees.
In the 1.8-million-hectare Manu Biosphere Reserve alone, some 925 bird
species have been recorded, making it one of the most species-rich protected
areas in the world. Between 1990 and 2000, however, Peru lost an average
of 269,000 hectares of forest cover annually, mainly due to illegal or
unsustainable harvesting of big-leaf mahogany (exported primarily to the
United States) and conversion to pasture and agriculture.
A standard solution to such an ecological crisis might entail creating
“no use” areas, with imaginary walls or very real armed guards
to keep humans out. However, in the Peruvian Amazon—a region that
figures prominently in the country’s economic future and whose population
depends heavily on its forest-based resources—strict protection
alone would be ineffective at holding change and disturbances at bay.
Instead, a more holistic solution is needed.
To that end, the World Wildlife Fund (WWF), an international nongovernmental
organization, is coordinating an ambitious forest conservation project
in the region, supported by a 5-year, $9.6 million grant from the U.S.
Agency for International Development’s Peru Mission. The Sustainable
Forestry Development Center project (CEDEFOR, by its Spanish acronym)
employs sustainable forest management as a mechanism for balancing economic
development and wildlife conservation and for addressing the threats facing
the region’s ecosystems. Partners, especially the Peruvian government
and local communities, will be essential to ensuring CEDEFOR’s success.
The WWF and local partners have been catalysts in the reform of the country’s
forestry sector. In the past, 1,000-hectare concessions were unregulated,
surreptitiously distributed, and aided in the laundering of illegally
harvested timber. Under the reformed system, they are openly and democratically
declared and designed to protect the region’s ecosystems. Still
federally managed and enforced, these concessions require owners to develop
forest management plans, implement reduced-impact logging, and make long-term
financial and conservation commitments. Typically, concessions are for
25,000 to 30,000 hectares (50,000-hectare maximum) and last 40 years with
options for renewal.
But concessions are simple contracts. Local people ultimately drive conservation,
so CEDEFOR is mobilizing Amazonian communities to form small-scale, sustainable,
private timber businesses. Those who were once exploited as laborers for
the forest’s destruction now own a stake in their future and in
the sustainability of the forests. Over the next 5 years, CEDEFOR will
guide some 100 local businesses in preparing sustainable forest management
plans, forest inventories, and biodiversity assessments and will bolster
their business acumen. Qualifying businesses will seek certification,
allowing them to market their timber as ecologically, economically, and
socially sustainable. Certification is an increasingly effective conservation
mechanism as consumers worldwide become more concerned with how and where
forest products are procured.
For the forests of the Peruvian Amazon, creating an untouchable museum
piece is not feasible, nor is allowing open “commons” to be
converted to agriculture and pasture. Such exhaustive pursuits offer little
hope for the region’s people, and even less for the bird species
with which they share these forests. Sustainable forest management, however,
offers long-term hope for both.

Something Ventured, Something Gained
by Krista De Groot and Barbara Robinson, Canadian Wildlife Service
For many years, conservationists across the continent have used the North
American Waterfowl Management Plan’s (Plan) joint venture model
to bring together diverse partners to conserve wildlife and its habitat.
The Canadian Intermountain Joint Venture, encompassing the south and central
interior of British Columbia and the Rocky Mountains of Alberta, was recently
endorsed by the Canadian Council of the North American Bird Conservation
Initiative. This makes it the fourth habitat joint venture in Canada,
the others being the Plan’s Pacific Coast, Prairie Habitat, and
Eastern Habitat Joint Ventures.
The Canadian Intermountain Region is a landscape of markedly varied elevation
and climatic conditions. This has resulted in an exceptional diversity
of habitat types including desert, grasslands, shrub-steppe, riparian,
wetlands, dry and moist coniferous forests, and alpine tundra. Due to
the wide range of habitats, it contains one of the most diverse breeding
bird faunas of any Canadian ecoregion. The region is home to 373 bird
species. Of this number, 254 species breed in the area and 83 species
occur during migration and/or in winter. In addition to its importance
to birds, the region hosts a diverse range of other taxa containing over
1,500 species of native vascular plants, 43 of native freshwater fish,
29 of amphibians and reptiles, and 94 of native terrestrial mammals.
The Region is also a managed working landscape that sustains growing
human populations. Resource-based industries, including crop agriculture,
ranching, forestry, energy, mining, tourism, and recreation, form the
economic base of most of the communities within the joint venture’s
boundaries. However, these activities, which support local economies and
urban communities, can have a profound influence on bird and other wildlife
populations.
The joint venture was established to address the challenges of sustaining
healthy populations of birds and other wildlife by providing regional
implementation of the North American Waterfowl Management Plan, the
Canadian Shorebird Conservation Plan, the Framework for Landbird Conservation
in Canada, and Wings Over Water: Canada’s Conservation Program for
Seabirds and Waterbirds. It complements, augments, and facilitates
existing conservation initiatives and partnerships and links internationally
to the Intermountain West Joint Venture in the United States to conserve
shared bird populations.
Many organizations have already invested significant resources and energy
into conservation efforts in the region, but realizing the joint venture’s
vision requires ongoing commitment. The joint venture provides an opportunity
to celebrate our conservation successes and use our existing resources
more efficiently through increased collaboration and communications. Joining
forces with new partners will help all stakeholders address the challenges
ahead.
