Natural Capital of Metchosin’s Coastline

orcamalefemodIn recent years, we have started to acknowledge that “Ecosystem services “ are something to which we must start paying attention as to fail to do so leads to a rapid decline in our quality of life:  Some of the ecosystem services that are part of Natural Capital are defined below, and a link to the Race Rocks website provides a model of how Ecosystem Services may be evaluated in a local ecosystem.

The following materials have been adapted from that resource:
Ecosystem services

‘Ecosystem goods’, such as food, and ‘services’, such as waste assimilation, represent the benefits humans obtain from a properly functioning ecosystem and are usually referred together as ‘ecosystem services’. Unsurprisingly a large number of ecosystem services have been identified, especially for the oceans which cover the majority of the planet and the coastal zone where the majority of humans live.

The items below might have a relevance for Metchosin’s coastal areas.

These include: gas regulation (e.g. maintaining a balanced chemical composition in the atmosphere), climate regulation (e.g. control of global temperature, precipitation, greenhouse gas regulation, cloud formation)
disturbance regulation (e.g. storm protection, flood control, drought recovery),
water regulation (e.g. regulation of global, regional and local scale hydrology through currents and tides),
water supply (e.g. storage of water returned to land as precipitation),
erosion and sediment transport/deposition (e.g. moving sediments from source areas and replenishing depositional areas),
nutrient cycling e.g. the storage, internal cycling, processing and acquisition of nutrients, nitrogen fixation, phosphorus cycles),
waste treatment (e.g. the breakdown of excess xenic and toxic compounds),
biological control (e.g. the trophic-dynamic regulation of populations),
refugia (e.g. feeding and nursery habitats for resident and transient populations of harvested species),
food production (e.g. the portion of gross primary production which is extracted as food for humans),
raw materials (e.g. the portion of gross primary production which is extracted as fuel or building material),
genetic resources(e.g. sources of unique biological materials for medicines),
recreation (e.g. opportunities for tourism, sport and other outdoor pastimes) and cultural (e.g. opportunities for aesthetic, artistic, educational, spiritual activities).

The value (the theoretical cost of artificially replacing the services were they not to be provided by nature) to humanity of these ecosystem services has been estimated at $8400 billion per year for the open oceans and 1.5 times this for coastal ecosystems. Consumptive use (production of food and raw materials) is a minor (<5%) component and therefore the true value of marine ecosystems is in non- consumptive use. However quantifying such use is notoriously hard.

It is our hope that while you are helping us to assemble the values of these Ecosystem services for Metchosin’s  you may be motivated to look in your own back yard and start placing a more realistic value on your own Ecosystems’ Services. ” Even today’s technology and knowledge can reduce considerably the human impact on ecosystems. They are unlikely to be deployed fully, however, until ecosystem services cease to be perceived as free and limitless, and their full value is taken into account.”

The Coastline of Metchosin is not as protected as the inner shores of the Victoria to Sidney area. Eelgrass needs protection and thus is minimally  important in our area as  fish habitat compared to the macro-algal kelp beds.

The following reference details the work done on the mapping of sea grasses in other areas of lower Vancouver island:
From: Island Trust Fund E-News Update March 27, 2013

Why we are mapping eelgrass

Seagrasses form large meadows that serve as nursery habitat and a refuge for juvenile fishes.  The leaves serve as a cornerstone for the marine food web, supplying nutrients to salmonids and other fish, shellfish, waterfowl and about 124 species of faunal invertebrates.

Eelgrass habitats within the Salish Sea provide the basis for the region’s commercial and recreational fisheries revenue.  The productivity of native seagrasses rivals the world’s richest rainforests.Eelgrass habitats capture and store large amounts of carbon at much more efficient rates than terrestrial forests.  Scientists estimate the salt marshes and seagrass meadows of B.C. sequester the equivalent of the emissions of some 200,000 passenger cars.

Contaminates and shoreline development put pressure on fragile eelgrass meadow ecosystems.  To protect eelgrass, we need to know where it is.  We’re mapping eelgrass habitat so that we can better plan our strategies to conserve these valuable underwater ecosystems

New Eelgrass Maps Released

The Islands Trust Fund is mapping nearshore eelgrass habitat in the Strait of Georgia and Howe Sound, in partnership with SeaChange Marine Conservation Society and the Seagrass Conservation Working Group.

Mapping of Eelgrass (Zostera marina) at Sidney Spit Marine Park, Gulf Islands National Park Reserve Using High Spatial Resolution Remote Imagery: by Jennifer D. O’Neill BSc, University of Victoria, 2006:

ABSTRACT: The main goal of this thesis was to evaluate the use of high spatial remote imagery to map the location and biophysical parameters of eelgrass at Sidney Spit Marine Park, part of the Gulf Islands National Park Reserve. To meet this goal, three objectives were addressed: (1) Define key spectral variables which provide optimum separation between eelgrass and its associated benthic substrates, using in situ hyperspectral measurements, and simulated IKONOS and Landsat 7ETM+ spectral response; (2) evaluate the efficacy of these key variables in classification of the high spatial resolution imagery, AISA and IKONOS, at various levels of processing, to determine the processing methodology which offers the highest eelgrass mapping accuracy; and (3) evaluate the potential of ―value-added classification of two eelgrass biophysical indicators, LAI and epiphyte type.

Coastal Jurisdiction in BC : History

In Metchosin when issues of development or cleanup of our coastal areas come along, we are often left wondering about which level of government has jurisdiction over marine issues. This file provides some of the background of those issues. It often determines who has responsibility for permitting development along shorelines, or even who cleans up when there is a coastal problem.

In 1979 this issue came to light when we were involved in having the ecological reserve created to a depth of 20 fathoms at Race Rocks. An ecological reserve created by the province, could only involve provincial territory, so the B.C. Attorney General’s Office was consulted by the then “Ministry of Lands Parks and Housing” for clarification. The reserve was created in 1980, but it took a Supreme Court of Canada decision in 1982 to make it official that the province really did have jurisdiction over the seabed that far out in the Strait of Juan de Fuca.

I have taken a quote from the admiraltylaw.com website which describes in Part 1-Who Controls the Offshore?, Some of the interesting history around this case in law. Note that the concern at the time for the upcoming importance of seabed resources such as oil, contributed to the urgency of this decision.

  • How British Columbia is Different: In 1967, British Columbia posed much the same question to the Supreme Court of Canada. The Court found that the seabed and its resources, from the mean low water mark to the outer limit of the Territorial Sea (12 nautical miles), was within the exclusive control of the Federal Government.However, like Newfoundland, British Columbia wasn’t satisfied with this answer. In 1981, the Province declared the entire coast an “Inland Marine Zone” (figure #1), in an attempt to assert its jurisdiction over the area. This declaration was political at best, and had little, if any, legal significance.In 1982, BC returned to the Supreme Court to ask the Court if the seabed resources between Vancouver Island and the mainland, particularly the seabed of Queen Charlotte Straight, Johnstone Straight, Georgia Straight and Juan de Fuca Straight, were within the jurisdiction of the Province.In deciding for the Province, the Court looked to the unique history of British Columbia. The Court found that when the Province was originally created as a colony by the British Parliament in 1866, its borders were defined with the most western outer limit of the Province being the “Pacific Ocean”. The court contemplated the meaning of “Pacific Ocean” and found that the water and seabed between Vancouver Island and the mainland were not commonly considered part of the Pacific Ocean and were therefore within the jurisdiction of the province.

    Importantly, we know from the Geological Survey of 1998 that the hydrocarbon reserves under these areas of Provincial control, particularly the Georgia Basin, contain minimal oil, but do contain modest natural gas reserves (6.5 trillion cubic feet). We further know from the 1998 Survey that the majority of BC’s offshore oil (9.8 billion barrels) and gas (26 trillion cubic feet) lies under the Queen Charlotte Basin in the Queen Charlotte Sound and Hecate Strait.Unfortunately for the BC government, the question posed to the Supreme Court in 1982 did not include a question as to who controls the bulk of the resources, those being under Queen Charlotte Sound and Hecate Straight. As a result, there is no binding authority that states specifically that those areas are under the control of the Federal Government. Indeed, if the Supreme Court were to find that Hecate Straight and Queen Charlotte Sound were not part of the “Pacific Ocean” proper, than the seabed resources would fall within the boundaries and the control of the Province. However, politicians may wish to settle this question themselves.Present Status of JurisdictionsAs it stands now, the province clearly has jurisdiction over the resources under the Queen Charlotte Straight, Johnstone Straight, Georgia Strait and Juan de Fuca Strait. The Federal Government, arguably, has jurisdiction over the vast majority resources under Queen Charlotte Sound and Hecate Strait. Whether the province will attempt to capitalize on its self-pronounced “Inland Marine Zone” and assert jurisdiction over the reserves under Hecate Straight is questionable as it would likely mean a long and drawn out legal battle. In the following article I will discuss how a similar battle was settled on the Atlantic coast, and why the approach taken there is likely the best approach for B.C.Before closing, it is interesting to note that the B.C. government could avoid a dispute over jurisdiction in Hecate Straight and still explore and develop a portion of the Queen Charlotte Basin. Maps forming part of the 1998 Geological Survey Canada show that a portion of this massive petroleum reserve lies under Graham Island. This oil can be accessed from Graham Island without the jurisdictional complications and the added complexity of drilling in the marine environment. The reserves directly under Hecate Straight might also be reached by drilling from land using directional and horizontal drilling. Although such ideas may successfully avoid a conflict of jurisdictions with the Federal Government, they still contain serious social, economic and political issues with respect to drilling on Haida Gwai.”

From this BC government page for Oil spills:

  • Guiding Principle
    The Province of British Columbia is committed to protecting British Columbia’s coastal environmental resources from harmful oil spills emanating from marine vessels, industrial facilities or inland sources.
    Because of its responsibility to protect and manage Crown lands, the Province is a major stakeholder in any marine oil spill. Its jurisdiction includes all land between the high and low water mark, the seabed of the Strait of Georgia, Juan de Fuca and Queen Charlotte Sound-Johnstone Strait, and the coastal seabed between major headlands unless responsibility has been transferred specifically to a federal jurisdiction or is in private ownership.
    Residing in or on these foreshore and seabed areas are provincial resources that include archaeological, recreational, heritage, wildlife and aquatic resources. Responsibility to protect and manage marine resources, such as waterfowl and fisheries, is often shared with federal agencies.
    It is these provincial and shared resources of the foreshore, offshore and seabed that are at risk from a spill and that are vital to many coastal communities for their livelihood.
    Since the federal government is also responsible for shipping and for certain other marine resources, responsibility to protect and manage marine resources is a joint effort between provincial and federal agencies.
  • Provincial Role
    The Province will take an active leadership and participatory role in coastal resource identification and, in the event of an oil spill, the protection and cleanup of the intertidal shoreline and seabed, which are under the jurisdiction of the Province.
    The Province’s response efforts will focus on the identification and mapping of provincial Crown resources, which include, but are not limited to, intertidal marine habitats, wildlife habitats and populations, archaeological, cultural, aquatic, park and ecological reserves.
    The Province will set priorities for resource protection and will establish oil spill protection and cleanup measures for shorelines. As well, it will ensure the availability of equipment and trained personnel to manage spill response safely and effectively.
    The Province will work in concert with federal agencies wherever both federal and provincial resources are to be protected.
    The level of response capability of the Province will also recognize the particular expertise and resources of the Canadian Coast Guard, Environment Canada, and Fisheries and Oceans Canada to undertake emergency response. Opportunities will be established for contractors to provide skilled assistance and resources in the event of a major spill.”

The Management Plan for the Race Rocks Ecological reserve also refers to jursisdictions:

  • “Cooperation with the Federal Government
    Jurisdictional responsibilities for the management of the marine environment and marine values are shared between the federal and provincial governments. For example, Fisheries and Oceans Canada (DFO) is responsible for the regulations of fisheries and the lead responsibility for navigation and marine mammal protection. The Coast Guard, an agency within DFO, is
    responsible for the automated lightstation on Great Race Rock. The Department of National Defence uses explosives in the area, which may also have impacts on the Reserve.
    The province, on the other hand, is responsible for the terrestrial areas, the seabed, and the natural values on those lands. The Province is working with federal agencies, including DFO, Parks Canada and Environment Canada, to develop and implement a marine protected areas strategy, and with Parks Canada to implement the Pacific Marine Heritage Legacy (PMHL)
    program.
    The highest level of protection for the Race Rocks area can only be achieved through the cooperative application of both federal and provincial authorities. “

Further Information about jurisdiction concerning coastal development can be found in  Coastal Jurisdiction in British Columbia (Green Shores) This is an excellent resource, summarizing the issues of coastal jurisdiction. It describes the limits of landowner, BC Crown and Federal jurisdiction along the coastal areas.

1. From Marine Ecosystem Services :
From http://www.compassonline.org/” : Humans derive benefits (or ecosystem services) from ecological systems. These services are produced by plants, animals, microbes and people interacting with one another and the physical environment. Scientists recognize four categories of ecosystem services: provisioning services such as food, fuelwood, fiber, and water; regulating services such as the regulation of climate, floods, coastal erosion, drought and disease; cultural services including recreational, spiritual, religious and other nonmaterial benefits; and supporting services such as nutrient cycling and photosynthesis. Some key benefits provided by the ecosystem services of functioning marine systems include healthy seafood, clean beaches, stable fisheries, abundant wildlife, and vibrant coastal communities.

Value of biodiversity and ecosystem services

The supply of ecosystem services depends on many attributes of biodiversity. The variety, quantity, quality, dynamics and distribution of biodiversity that is required to enable ecosystems to function, and the supplying benefits to people, vary between services. The roles of biodiversity in the supply of ecosystem services can be categorized as provisioning, regulating, cultural and supporting, and biodiversity may play multiple roles in the supply of these types of services.

  • For example, in agriculture, biodiversity is the basis for a provisioning service (food, fuel or fibre is the end product),
  • a supporting service (such as micro-organisms cycling nutrients and soil formation),
  • a regulatory service (such as through pollination), and potentially,
  • a cultural service in terms of spiritual or aesthetic benefits, or cultural identity.

The contributions of biodiversity-dependent ecosystem services to national economies are substantial. The science of valuation of ecosystem services is new, and still developing basic conceptual and methodological rigour and agreement, but it has already been very instructive, since the value of such services is generally ignored or underestimated at decision and policy making levels. Identifying economic values of ecosystem services, together with the notions of intrinsic value and other factors, will assist significantly in future decisions relating to trade-offs in ecosystem management.

  • Value of: Annual world fish catch – US$58 billion (provisioning service).
  • Anti-cancer agents from marine organisms – up to US$1 billion/year (provisioning service).
  • Global herbal medicine market – roughly US$43 billion in 2001 (provisioning service).
  • Honeybees as pollinators for agriculture crops – US$2–8 billion/year (regulating service).
  • Coral reefs for fisheries and tourism – US$30 billion/year (see Box 5.5) (cultural service).
  • Cost of: Mangrove degradation in Pakistan – US$20 million in fishing losses, US$500 000 in timber losses, US$1.5 million in feed and pasture losses (regulating provisioning services). Newfoundland cod fishery collapse – US$2 billion and tens of thousands of jobs (provisioning service).

Of those ecosystem services that have been assessed, about 60 per cent are degraded or used unsustainably, including fisheries, waste treatment and detoxification, water purification, natural hazard protection, regulation of air quality, regulation of regional and local climate, and erosion control Most have been directly affected by an increase in demand for specific provisioning services, such as fisheries, wildmeat, water, timber, fibre and fuel. “

Aquatic ecosystems provide many services contributing to human well-being .Maintenance of the integrity and the restoration of these ecosystems are vital for services such as water replenishment and purification, flood and drought control.

A assignment that defines the ecosystem services of Race Rocks
This page with curricular ideas is based on the original found at:
http://www.racerocks.ca/ecology/ecosystemservices/
Although it is targeted as an exercise for Race Rocks, It could be used similarly in any other ecosystem.

See below for a preview:

In recent years, we have started to acknowledge that “Ecosystem services ” are something to which we must start paying attention as to fail to do so leads to a rapid decline in our quality of life: This file explores that idea further and invites you to contribute to a new project :
DEFINING THE ECOSYSTEM SERVICES of RACE ROCKS.
It is our hope that while you are helping us to assemble the values of these Ecosystem services for Race Rocks, you may be motivated to look in your own back yard and start placing a more realistic value on your own Ecosystems’ Services. ” Even today’s technology and knowledge can reduce considerably the human impact on ecosystems. They are unlikely to be deployed fully, however, until ecosystem services cease to be perceived as free and limitless, and their full value is taken into account.”

OBJECTIVES: After doing this assignment,students will beableto:

1. Define what is meant by the terms ecosystem services.

2. Define what is meant by the term Natural Capital.

3. Enumerate the Ecosystem services of Race Rocks.

PROCEDURES:

1. Using the references below, investigate what is meant by Natural Capital and Ecosystem Services. Make a table where you can list the ecosystem services which you think are provided by an area like Race Rocks. In the table make a dollar estimation of the value of that service per year.

2. Using the area where you live, make a list of the ecosysterm services provided by your local ecosystems, and rate which you think are the most important.

Here are some ideas to get you started:

  • You will observe commercial whale/marine mammal/bird/-watching boats in the area.. how many passengers do they carry and what is the value generated per trip.
  • You may see tankers and others vessels going by which you can also record . Race Rocks has a lighthouse and foghorn.. What is the value to ships of this set of islands for navigation?
  • Research is done at Race Rocks by students of schools, colleges and universities? What is the value of this location for research and education?
  • An Integrated Energy System was developed at Race Rocks. What is the value of this to BC Parks, to the BC government, to Pearson College?
  • A number of viewers around the world use Race Rocks as a location for bird and animal viewing. See the examples from England which are linked to the Daily Log
  • The role of marine protected areas in conservation is a world wide goal. How does the Management Plan for Race Rocks reflect ecosystem services provided by the area. http://www.env.gov.bc.ca/bcparks/planning/mgmtplns/race_rocks/racerock.html

recreation (e.g. opportunities for tourism, sport and other outdoor pastimes) and cultural (e.g. opportunities for aesthetic, artistic, educational, spiritual activities).The value (the theoretical cost of artificially replacing the services were they not to be provided by nature) to humanity of these ecosystem services has been estimated at $8400 billion per year for the open oceans and 1.5 times this for coastal ecosystems. Consumptive use (production of food and raw materials) is a minor (<5%) component and therefore the true value of marine ecosystems is in non- consumptive use. However quantifying such use is notoriously hard.Adapted from the reference:
