Download the entire conservation plan (1.65 MB pdf file)

The purpose of this conservation plan is to elucidate the wildlife values in the Baynes Sound/Lambert Channel-Hornby Island Waters Important Bird Areas, discuss the issues that may affect these values, introduce and highlight the initiatives that are addressing some of these issues, and to focus and direct future initiatives that could further address identified concerns.

What is an Important Bird Area?
An Important Bird Area (IBA) is a site providing essential habitat for one or more species of breeding or non-breeding birds. These sites may contain threatened species, endemic species, species representative of a biome, or highly exceptional concentrations of birds.

The goals of the Canadian IBA program are to:

  1. identify a network of sites that conserve the natural diversity of Canadian bird species;
  2. ensure the conservation of sites through partnerships of local stakeholders who develop and implement appropriate on-the-ground conservation plans
The Baynes Sound/Lambert Channel-Hornby Island Waters IBAs
This complex of two IBAs is situated on the east coast of Vancouver Island. The Baynes Sound IBA extends from the Courtenay River estuary at the head of Comox Harbour to Deep Bay and Mapleguard Point approximately 35 kilometres to the southeast. Included in this IBA is Chrome Island, which is situated off the southern point of Denman Island. The Lambert Channel-Hornby Island Waters IBA includes the body of water that separates Denman and Hornby Islands as well as the shores of eastern and southern Hornby Island, especially the marine reserve associated with Helliwell Provincial Park and the marine portion of Tribune Bay Provincial Park. Included in this is a one-kilometre radius around Flora Islet.

The foreshore areas and marine waters that encompass these two IBAs represent one of the most significant areas for wintering and migratory waterbirds in BC. Within in the bounds of the two IBAs, a total of nine bird species have reached globally significant levels, three have reached continentally significant levels, and one species has reached nationally significant levels. The predominance of this region as a significant area for several species of birds is due largely to the variety of different habitats and hence sources of food available to birds. The combination of sheltered and exposed waters together with the resultant varying intertidal substrates have given rise to a wide range of different habitat types such as inshore and foreshore marshes, low gradient deltas and tidal flats. This region is also one of the most productive Pacific herring spawning areas and shellfish growing areas in BC.

Conservation issues in the Baynes Sound/Lambert Channel-Hornby Island Waters area

Like many coastal regions of the world, the east coast of Vancouver Island in the vicinity of these two IBAs has undergone significant changes. Recent population increases in the region have resulted in a number of issues that potentially impact the birds in these two IBAs. These include pressures on shoreline and associated habitats due to urban development; water pollution from non-point sources (e.g., failing rural septic systems, faulty storm drains, agricultural runoff, boater waste), and human disturbance (e.g., wildlife viewing). Other conservation concerns relate to the health of the Pacific herring stocks, and expansions to the shellfish industry in the area.

Current conservation actions and activities

The Baynes Sound/Lambert Channel-Hornby Island Waters area has long been recognized as an important area for waterbirds, salmon, herring and shellfish. In recent history, development in this area has resulted in significant impacts to the natural environment. In response to the challenges that development has brought, the area has seen the establishment of an numerous community-based conservation initiatives. The Baynes Sound Stewardship Action Group (BSSAG) is an aggregation of project orientated community, government and industry groups that meet on a monthly basis to address local conservation concerns. This group includes Comox Valley Project Watershed Society, Comox Valley Citizens for Action on Recycling and the Environment, the BC Shellfish Growers Association, BC Ministry of Fish, Environment Canada, the local health unit, and others depending upon current project focus. BSSAG employs a collaborative problem-solving approach to the mitigation of local health and environmental issues.

Because of the tradition of action-based conservation activity in this region, the opportunities for effective conservation are numerous and are generally limited by access to project and core funding, rather than the capacity to design and implement the necessary projects. The IBA program will help focus conservation activities in this area. By doing so, waterbirds can be incorporated in to the various projects in the region. In addition, highlighting the birds within these IBAs can help galvanize support for conservation activities both inside and outside the community. The IBA program in this area is helping to connect agencies and programs together to support conservation related work in the region.

Conservation Goals and Objectives

The conservation goals and objectives for the Baynes Sound/Lambert Channel-Hornby Island Waters IBA encompass four main focal areas: program integration, water quality amelioration, education and outreach, and research and monitoring. In many cases these programs are ongoing but are always limited by available funding. In almost all instances the infrastructure and personnel are present within the community to accomplish most of the tasks required. The long-term capacity of these two IBAs to support the birds presently found here (resident and migratory) will be enhanced by the achievement of these conservation goals and objectives.
  1. Program integration: the development of an information management system
    Given the large geographic size of this area, and the number of different conservation initiatives that are ongoing it is critical to line diverse initiatives together. The State of the Sound Program, led by Comox Valley Project Watershed Society (Project Watershed) will create a system for the long-term management and reporting of water quality and conservation actions in the Baynes Sound region. This system will facilitate community access to information, improve awareness and understanding about stewardship issues, and increase public participation in decision-making and policy development related to water quality and conservation issues. This program is in its initial development stages and will require secure funding to fulfil its potential.
  2. Water quality amelioration: making the water cleaner throughout the region
    Water quality is a key component in the conservation efforts in this area as problems associated with water quality can have far reaching affects on the entire ecosystem in the region. Deterioration of water quality can directly affect human health, result in economic losses for those industries that rely on clean water (e.g., the shellfish industry), and negatively impact spawning habitat for Pacific herring and the feeding habitat for various species of waterbirds. Water quality problems in the area result from several types of non-point source pollution, including failing septic systems, boater waste, and hazardous waste disposal.

    Failing septic systems

    Water quality problems associated with failing septic systems have been chronic in the region. Presently, there are several initiatives that are actively addressing this issue. These initiatives include:

    Septic seminars/socials: a community out reach program implemented by Comox Valley Citizens for Action on Recycling and the Environment (CVCARE) demonstrates the proper care and maintenance of a septic system. This program has been extremely successful in selected locations in the area, but requires additional funding to be implemented over a larger area.

    Union Bay Waste to Wealth Project: a project that will research innovative approaches to the treatment of wastewater at a community level. It will include constructed wetlands, solar greenhouses and vermi-composting. This project will represent a significant contribution to water quality amelioration in the region. Should this program prove successful, it could be used as a model for similar sized communities in the region and throughout BC.

    Hornby Island constructed wetland and grey water treatment system: a project implemented by CVCARE examines the feasibility of using a small constructed wetland and grey water treatment system to treat waste from individual residences. The program is well suited for this region, as well as many coastal communities in BC.

    Biofiltration Wetlands: these small constructed wetlands built by Project Watershed in conjunction with the Department of Highways improve the water quality of stormwater runoff and wastewater effluent, while creating valuable wildlife habitat. Within the region there are numerous areas that could benefit from these projects.

    Boater waste
    Construction of boater pump out facilities is planned at each end of Baynes Sound (Comox Harbour and Deep Bay). These facilities will provide an alternative to dumping raw sewage into the marine waters of Baynes Sound.

    Hazardous Waste disposal

    Spring Clean-up was a pilot project developed and implemented in the spring of 2000 by CVCARE that focused on raising awareness of the misuse of hazardous chemicals, and offered information on using safer alternatives. The campaign culminated in a hazardous waste drop-off day for all citizens of the Comox Valley. This project may be repeated in following years, pending long-term funding.

  3. Outreach/Stewardship: increasing the awareness of conservation issues and providing useful information and practical tools

    Business Partners for Clean Water

    This program initiated by Project Watershed will involve local businesses in the automotive, marine, landscaping, building maintenance, construction, and other business sectors whose activities contribute to water quality problems in Baynes Sound. At least 200 businesses will be invited to participate as “Business Partners”, and will receive best management information that will prevent and/or reduce levels of toxic substances entering wastewater disposal systems as a result of their business activities.

    Clean Boating handbook

    The Baynes Sound Boaters Guide produced by Project Watershed, outlines responsible boating operation including such activities as sewage and engine waste disposal, and boat maintenance. Future editions may include a wildlife viewing component either as an addition to the original document, or as an insert (e.g., BC Parks Living with Wildlife).

    Sound management of marinas

    A program initiated by Project Watershed that is in the early stages of development will focus on how marina operators can carry out business in an ecologically sensitive manner. If feasible this program will be extended to boaters, both recreational and commercial. The initiation of this project is pending the acquisition of sufficient funding.

    Disturbance to wildlife

    Ecotourisim and use of natural areas such as Provincial Parks have increased throughout coastal BC. One of the consequences of these activities is the disturbance to wildlife. The disturbance to wildlife in this region is an issue that will undoubtedly escalate as the popularity of wildlife viewing increases, and as the population in the area increases. It is therefore important that the public be made aware of how disturbance affects wildlife, and how to share the waters with wildlife without causing undue disturbance. The production of information material on how to utilize natural areas with due care and attention will help reduce the detrimental consequences for wintering birds that uninformed use of these areas can cause. Signage at local boat launching areas and marinas, and within high use areas (e.g., Provincial Parks) can also reduce these impacts.

    Foreshore stewardship

    One of the most important activities that could be implemented in this region is a foreshore stewardship program. One component of this program, proposed by Project Watershed, is the mapping and inventory of foreshore wetlands, and wildlife habitat for government and private landowners. In addition, the marine section of the Living by Water Program initiated by the Federation of BC Naturalists could be modified and expanded in order to more thoroughly address marine issues such as the alteration of marine wetlands, the role of large trees as potential heron and raptor nest sites, and disturbance of sensitive wildlife habitat areas such as herring spawning areas and heron colonies.

    Stewardship of another sort: connections between birds and shellfish growers who are outside the BC Shellfish Growers Association


    Presently the BC Shellfish Growers Association, the BC IBA Program and the CWS are developing a waterbird supplement for the shellfish industry’s best management practices. This supplement integrates waterbird natural history with shellfish growing operations in order to minimize the conflict between growing operations and waterbirds. It will be important that this material be extended to the numerous businesses that do not belong to the BCSGA in order to include as many growing operations as possible.

    Increased awareness of birds in winter

    The development of signage in appropriate locations that highlights the area as a globally important wintering area for waterbirds may increase the connection of local inhabitants to the area, and thereby potentially influencing day-to-day interactions with the natural environment. Content material for these signs would include how development, resource use, and day-to-day living affect major limiting factors such as water quality, disturbance to birds, and foreshore and herring spawning habitat, and how to responsibly interact with this resource.

Research and Monitoring: ensuring the availability of meaningful data

  1. Waterbird monitoring
    Presently, the Coastal Waterbird Survey, conducted by local natural history organizations in conjunction with Bird Studies Canada, is a vehicle that can track potential changes in bird distribution within this area. It is therefore critical that this program continues as it is currently providing valuable data on which changes in abundance and distribution of birds can be based upon.
  2. Exploration of the relationship between shellfish growing activities and waterbird biology
    Concerns raised by numerous individuals (both government and non-government) regarding the potential impact of shellfish industry on waterbird foraging habitat suggest that a long-term, carefully thought out and well-planned research project will be necessary to address these concerns.
  3. Great Blue Herons
    Declines in the numbers of Great Blue Herons in coastal BC indicate that an examination of heron foraging habitat is warranted.

INTRODUCTION
The east coast of Vancouver Island and associated gulf islands represent extremely important habitat for a wide variety of birds both during the breeding and non-breeding seasons. The coastal waters stretching from Comox, to Maple Guard Point on Vancouver Island, including the waters surrounding both Denman and Hornby Islands, represent one of the most significant areas for wintering waterbirds in BC.

Presently this area encompasses two IBAs. The Baynes Sound IBA includes the marine and foreshore areas between Vancouver Island and Denman Island. The Lambert Channel-Hornby Island Waters IBA includes the body of water that separates Denman and Hornby Island as well as the shores of eastern and southern Hornby Island, especially the marine reserve associated with Helliwell Provincial Park and the marine portion of Tribune Bay Provincial Park. Included in this is a one-kilometre radius around Flora Islet.

The predominance of this region as a globally significant area for several species of birds is due largely to the variety of different habitats present in this area. The combinations of sheltered and exposed waters together with the resultant varying intertidal substrates have given rise to a wide range of different habitat types including inshore and foreshore marshes, low gradient deltas and tidal flats that receive input from nutrient rich river systems, and rocky intertidal beaches. These numerous different habitats support a complex food web that supports a wide range of birds species including fish eating species such as herons, loons and cormorants; diving ducks such as buffleheads and scoters that prey on gastropods and bivalves; shore birds that feed in the exposed intertidal areas such as Turnstones and Dunlin; and dabbling ducks, geese and swans that feed upon the emergent vegetation of estuarine and foreshore habitats. One of the most important sources of food for birds in this area is the prolific herring spawn that occurs throughout the region. During the peak of the herring spawn upwards of 60,000 birds descend upon the foreshore areas of the region to feed upon adult herring and their eggs (Haegele 1993).

Like many coastal regions of the world, the east coast of Vancouver Island in the vicinity of these two IBAs has undergone significant changes. The east coast of Vancouver Island is one of the fastest growing areas in Canada. The area is presently experiencing an annual growth rate of 7% (MABF 1999). Furthermore, the long history of European settlement in the region has resulted in a wide array of land uses, many of which can have a negative impact on natural ecological processes. The present land uses include urban and suburban regions, agriculture, commercial forestry and log storage, recreational boating and associated infrastructure (marinas), commercial fisheries, and aquaculture. This increased human presence in the area has influenced the quality and quantity of both the marine and foreshore habitats. Urbanization, agriculture, commercial fishing and recreational boating in the area have led to declines in water quality throughout out the region (Vermeer and Ydenberg 1989). The deterioration of water quality has had widespread impacts, especially for the commercial aquaculture industry in the area. Similarly increased settlement has seen the reduction of saltwater marshes (Campbell-Prentice and Boyd 1988, Dawe et al. 1998) as well as the forested foreshore areas. The intensive shellfish industry has also raised concerns about affect on the availability of waterbird foraging habitat (Savard 1989, Axys 2000).

Furthermore, disturbance to nesting, roosting, moulting and feeding birds from water-based activities such as ecotourisim and recreational boating has also increased in the area.

Human induced changes in this region have not gone unnoticed by local residents, and all three layers of traditional government. Within the region there is a strong and vibrant community of local organizations who have designed, developed, and implemented a wide variety of measures and programs that have addressed some of the major environmental concerns in the region. These range from small scale programs that involve individual land owners (septic seminars), to projects that will influence entire communities (Union Bay Waste to Wealth) to initiatives that will track environmental activities over a large geographic area.

These IBAs have been grouped together in to one conservation plan because, with minor exceptions, similar bird species are found in both IBAs. In addition, conservation concerns are similar in both IBAs. The purpose of this conservation plan is to elucidate the wildlife values in the area, discuss the issues that may affect these values, introduce and highlight the initiatives that are addressing some of these issues, and to focus and direct future initiatives that could further address identified concerns.
