Wetlands and Watersheds: East Annex Project
by Leigh Patterson and Joy Gregory, Ducks Unlimited Canada
What began as a simple drainage project is now a model of multi-agency
and community co-operation in watershed planning. The East Annex Project
is a restored wetland/upland complex that spans 5 square miles and successfully
meets the needs of all partners while retaining the integrity and "best
use" of the land.
The project is situated near Big Hay Lake, 25 kilometers northwest of
Camrose, in the heart of central Alberta's Aspen Parkland Biome. Characterized
by its abundant and diverse wetland habitat, this biome is a North American
Waterfowl Management Plan priority area.
East Annex lies within a flood-prone area in the Big Hay Lake Drainage
District (District). The original project design proposed by the District
with Alberta Environment would have seriously reduced or eliminated the
area's remaining wetland base. Instead, Ducks Unlimited Canada (DUC) encouraged
a watershed management plan that emphasized maintaining and restoring
wetlands. According to Michael Barr, a DUC biologist in Camrose, "The
project addresses the full range of watershed management needs, from flood
control and habitat conservation to improvement of prime agricultural
lands."
The project included a combination of new drains or drain improvements,
landowner access crossings, and dams or dykes with variable-level water-control
structures. Two significant wetland restorations totaling 214 acres were
involved in the design. One is a managed backflood (Washing Lake) and
the other a permanent basin (Mallows Lake). The total wetland area increased
from 165 acres to 379 acres.
The East Annex Project was co-operatively planned, designed, and negotiated
over several years and was finally completed in 1999. Integral to its
success was the partnerships established with local landowners. "We
saw it as a project where the community and habitat conservationists both
had something to gain," says Alberta Environment Water Management
Engineer Doug Yeremy. "It is an example of sound water management
that gives the community an opportunity for input into the process of
watershed planning."
It's a "win-win" situation for everyone. With the largely expanded
wetland area, the waterfowl breeding population is expected to more than
double. The backflood area at Washing Lake enhances habitat for spring
breeding pairs and migrant shorebirds. As the water is drawn down, more
vegetative cover is provided to promote nesting. This also benefits farmers
because native hay cuts can be made after nesting season when the water
level is lowest and hay quality and quantity are maximized. The permanent
wetland area at Mallows Lake also provides essential and continuing habitat
for diving ducks, grebes, black terns, and other wetland-dependent wildlife.
The East Annex Project is an example of how watershed issues can be resolved
for the benefit of people and wildlife. Overall, this project is favored
by the local community. It serves as an example for future projects with
landowners.

Big Sandy Bay
by Linda Turner, Nature Conservancy of Canada
Thousands of ducks, geese, and other migratory birds can continue to
safely stop over at Big Sandy Bay, located on the southwest corner of
Wolfe Island in Lake Ontario, just south of Kingston. Primarily an alder,
willow, black ash, soft maple, and cattail swamp, the wetland is found
on a relatively flat limestone shoreline behind 35 acres of sand dunes
and a small area of open-water marsh.
Big Sandy Bay is now protected because Nature Conservancy of Canada (NCC),
Ontario Region, worked in conjunction with Environment Canada's Canadian
Wildlife Service, Ontario Ministry of Natural Resources (MNR), Ducks Unlimited
Canada (DUC), and the U.S. Fish and Wildlife Service to purchase the 140-acre
wetland for just over $160,000.
As part of its commitment to the North American Waterfowl Management
Plan, NCC began negotiations after hearing from Kingston's DUC chapter
that the site was for sale. The property is now protected and managed
as a wildlife area by the MNR.
Little wonder that the ducks love itBig Sandy Bay has it all. A
gently sloping limestone plain leads to sandy shoreline and a wetland
basin that developed behind a barrier sand bar. There is a large swamp
thicket, a shoreline marsh, a deciduous swamp forest, a bog, coastal sand
ridges, and dunes. There is even a small upland sugar maple, American
beech, and red oak grove. The surrounding interior plains have two limestone
peninsulas that jut out into the lake, forming a wetland basin that supports
habitat best suited to attract black-crowned night heron, least bittern,
northern pintail, northern shoveler, northern harrier, black tern, and
sedge and marsh wrens.
On Big Sandy Bay, the American bittern, caspian and common terns, common
moorhen, American woodcock, common snipe, and diving ducks, such as goldeneye,
bufflehead, and scaup, share space with muskrat, raccoon, mink, and fox.
Nesters that can be found on the bay are gadwall, northern pintail, blue-winged
teal, American wigeon, northern shoveler, and wood duck. The wood ducks
take advantage of boxes placed in the wetland.
Before the Eastern Habitat Joint Venture protected Big Sandy Bay, the
property was threatened by residential development, farmland encroachment,
and all-terrain-vehicle disturbance of the sand dune and beach habitat.
Now the ducks, geese, and other migratory birds have a preserved, safe,
and supportive habitat.
"The preservation of Big Sandy Bay is a perfect example of the benefits
to Great Lakes habitat when conservation organizations work effectively
together to accomplish Plan goals and the concrete result of our commitment
to that science-based program," commented James Duncan, Director
of Land Protection, Ontario Region, Nature Conservancy of Canada.

Saskatchewan's Barvas Marsh Complex
by Leigh Patterson, Ducks Unlimited Canada
The Barvas Marsh Complex in east-central Saskatchewan is a rare remnant
of native parkland habitat within a landscape of intensive agriculture.
Left in an idle state for over 20 years, it is a mosaic of native grass,
forbs, shrub, and tree species combined with a range of productive wetlands.
Located east of Yorkton, this 960-acre purchase and lease falls within
the North American Waterfowl Management Plan's (Plan) Pheasant Hills Key
program area. According to Ducks Unlimited Canada (DUC) biologist David
Kostersky, the complex is significant due to the large acreage of intact
native habitat. This is no small measure of achievement, considering that
over 70 percent of the region's native prairie and wetlands have been
cultivated and drained. The Barvas marsh system falls within the Upper
Assiniboine River Basin watershed, where drainage is very active and wetland
loss and disturbance extensive. In fact, remains of old drainage works
built in the 1930s and 1940s were discovered running through several of
the Barvas wetlands now protected under the Prairie CARE (Conservation
of Agriculture, Resources and Environment) purchase and lease programs.
The cooperating landowners who agreed to sell or lease their land are
"good neighbours," says Kostersky. "The soil quality of
Barvas is poor, so they didn't lose land with agricultural value."
Since the project was functioning well after being idle for so long, restoration
work was not necessary. Further management of the complex will be determined
over the next 3 years.
The habitat acquisition through Plan partners contributes greatly to
biodiversity conservation. Its wetlands are shallow and interspersed with
vegetation providing ideal habitat for breeding, moulting, and staging
waterfowl. Many other avian species, amphibians, insects, and mammals
also benefit.
To promote inter-agency cooperation, DUC partnered with the Yorkton Natural
History Society (Society) to conduct periodic plant and animal surveys
at the complex. Using a multi-species inventory checklist designed by
Nature Saskatchewan and DUC, volunteers from the Society recorded 72 bird,
9 mammal, 90 flowering plant (including the rare yellow lady's slipper),
2 frog, 1 toad, 12 grass, 2 trees, and 5 shrub species. Accumulation of
this baseline data is critical to understanding and quantifying prairie
biodiversity. It also helps measure the impact of Plan programs on the
prairie land base, enabling resource managers to make informed decisions.
These surveys have piqued the interest of media and the conservation community,
garnering the Society and DUC-Yorkton the 1995 Nature Saskatchewan Annual
Conservation Award.
Growing interest in natural areas, like the Barvas Marsh Complex reinforces
the importance of conservation. The complex offers self-guided nature
tours designed by DUC's Nature Watch Program.
Meanwhile, threat of fragmentation of other valuable remnants looms large.
The unsecured areas of relatively intact, native parkland habitat surrounding
the Barvas Marsh Complex are currently at high risk of loss. According
to Kostersky: "DUC is continuing to pursue all avenues of habitat
securement to ensure this extremely diverse and productive area remains
intact."
