Wetlands
Wetlands provide some of the
most biologically diverse, productive and important life support systems on
earth. They provide critical habitat
for amphibians, reptiles, fish, birds, and other wildlife. Most wildlife in BC use wetland habitat at
some point in their life cycle, and many red and blue-listed species are
dependent on wetlands.
In addition to wildlife
habitat, wetlands provide important natural services such as flood control,
water storage, water purification, contaminant filtering, and control of storm
water and erosion. Wetlands are
sometimes artificially constructed in some land developments in order to
provide these benefits. Hence, wetland
protection is now seen to be important for economic as well as conservation
reasons.
Some estimates have suggested
that British Columbia has lost between 60 to 85 per cent of its original
wetlands, depending on the region. Most
losses have occurred as a result of drainage of wetlands for agriculture and
urban development.
Protection of Wetlands
The importance of wetlands was
recognized internationally in 1971 under the International Convention on
Wetlands, also known as the Ramsar Convention (see the Guide page on
Multilateral Environmental Agreements). British Columbia has two internationally
significant wetlands sites – the Alaksen National Wildlife Area in the Fraser
River delta, and the Creston Valley Wildlife Management Area south of Kootenay
Lake.
The Ramsar Convention calls
upon its signatories to conserve and protect wetlands. The federal government adopted the Federal
Policy on Wetland Conservation in 1991, which stipulates the goal of “no
net loss” to wetlands on federal lands or waters. However, most wetlands come under provincial jurisdiction. British Columbia does not yet have a
wetlands policy, although several other provinces have adopted policies similar
to the federal policy.
There are, however, both
provincial and federal laws that may apply to wetlands. Provincially, the Forest
Practices Code of British Columbia Act, Water Act,
and Wildlife Act are the main laws that affect wetlands
(as well as associated provincial planning processes)
located on public lands. The Forest
Practices Code regulates logging activities around wetlands by requiring a
system of “reserve zones” and “management zones” depending on the size of the
wetland. The Water Act requires
provincial approval for changes to streams, which include wetlands. The Wildlife Act allows for the protection
of wildlife management areas, many of which contain wetlands. Some provincially important wetlands are
protected under this designation.
Federally, the Fisheries Act and Canada Wildlife Act
are the main laws that affect wetlands.
The Fisheries Act protects all “water frequented by fish,” which
includes wetlands associated with estuaries and fish streams. The main protections are the prohibition
against harmful alteration, disruption or destruction to
fish habitat, and the prohibition against depositing any substances that are deleterious to fish. The Canada Wildlife Act allows for the
designation of national wildlife areas on lands administered by the federal
Minister of Environment. This
designation has been used to protect wildlife habitat that includes wetlands.
At the local level, there is
provision in the Local Government Act and incoming
Community Charter to designate environmentally sensitive areas such as wetlands
in official community plans, regional
growth strategies, and development permit areas. Local Governments may also plan for stormwater (water running into wetlands and
rivers due to urban development) or green areas, both
of which may have an impact on wetlands.
In addition, there are
non-regulatory tools that can be useful in protecting wetlands on private land,
such as conservation covenants, in which a landowner
and conservation organization or local government voluntarily reach agreement
on the use of property and register a covenant with the Land Title Office.
