Indicator 5.3.2 - Annual harvest of nontimber forest products relative to the level of harvest deemed to be sustainable
supporting indicator
Nontimber forest products (NTFP), which include
hundreds of products and all products generated
directly or indirectly from organisms living in forest
ecosystems, are thought to contribute approximately
$1 billion to the Canadian economy (Indicator 5.1.4).
The increasing demand for NTFP and their valueadded
products suggests that it is important to coordinate
the activities of the timber industry with those
of the NTFP industry.
NTFP offer economic opportunities, especially in
rural and Aboriginal communities where they provide
various forms of income to a wider section of society
than the traditional timber industry. Although NTFP
have been a part of traditional cultures for centuries,
there is increasing global demand for these products.
However, it is still a fledgling industry that is uncoordinated
and in need of regulatory and policy
frameworks to ensure appropriate management
and controlled expansion.
Several basic issues must be clarified in order for
NTFP to realize their potential. For instance, social
research needs to determine how the inclusion of NTFP
considerations into forest management could improve
the social well-being of communities. Developing social
indicators to track how NTFP increase the social wellbeing
of a forest-dependent community will be useful.
Considering that NTFP often come from the same
land base as timber products, there may be situations
where a choice will have to be made between traditional
timber harvesting and NTFP harvesting. From
an economic standpoint, it will therefore also be critical
to determine how to maximize the value of NTFP and
timber products extracted from the forest.
Furthermore, there is a need to address the policy,
legal, and regulatory frameworks for NTFP harvesting,
processing, and marketing. Much of the NTFP are
currently produced privately, originating on private
land and are therefore not registered or subject to
regulation. Market demand could therefore quickly
increase harvesting of NTFP to unsustainable levels if
proper regulatory frameworks are not in place. The
complicated issues involved in managing property
rights have been outlined for British Columbia by
Tedder et al. (2002), but potential solutions have not
yet been tested.
Finally, research needs to determine what NTFP are
available in different forest types and age classes, and
actual stocks of these products should be monitored
to determine sustainable harvest levels under different
conditions. The latter is needed to be able to report on
the status of this indicator. It will also be important
to determine which best management practices will
sustainably increase NTFP yields; however, the broad
range of NTFP and conditions in Canada make this
a challenge.
There is increasing interest in research into NTFP
across the country. The following examples present
a sampling of the efforts currently underway to
improve the sustainability of NTFP extraction:
. Royal Roads University, Victoria, British
Columbia, has recently established a Centre
for Non-Timber Resources that aims to promote
the sustainable use of nontimber resources
through activities such as research, education,
capacity building, policy, and stewardship.
It offers courses dealing with various aspects
of NTFP management (www.royalroads.ca).
. The Northern Forest Diversification Centre
(NFDC) (http://www.nfdc.ca/about.htm)
in Manitoba acts as a research, training, marketing,
and sales center for NTFP. Its catalogue
features over 300 products, ranging
from botanicals to wreaths and indigenous
items. The NFDC is actually working with
Royal Roads University to develop a western
Canadian NTFP network that would range
from Manitoba to the Yukon.
. The Harrop-Procter community forest, situated
in one of the world's few remaining interior rainforests
in British Columbia's West Kootenay
region, is committed to the management of
NTFP and was, in fact, the first agreement or
tenure in the province to include commercial
NTFP harvesting (http://www.hpcommunity
forest.org/).
. In Quebec, the Collège Sainte-Anne-de-la-
Pocatière (http://leadercsa.com/) offers courses
dealing with NTFP stewardship. Similarly, the
Centre québécois de valorisation des biotechnologies
(http://www.cqvb.qc.ca/) is engaged
in NTFP management, and one of its technology
transfer projects dealt with the production
of taxanes from ground-hemlock in Quebec to
produce the cancer-treating drug Taxol® (see box).
. Finally, in New Brunswick, the Falls Brook Centre
(http://www.fallsbrookcentre.ca/), which also
works on ground-hemlock sustainability through
the Eastern Canada Ground-Hemlock Working
Group (ECGHWG-http://www.atl.cfs.nrcan.
gc.ca), promotes inclusion of NTFP in sustainable
forest management.
Treating Cancer with Taxol® from
Ground-hemlock
Ground-hemlock ( Taxus canadensis) is used as a source
of raw material in producing the anticancer drug paclitaxel
(Taxol®). Ground-hemlock harvest has been plagued with
theft and numerous examples of unsustainable harvest
at the current harvest level of 680 000-2.2 million kg
per year. An estimated 400 kg per year of paclitaxel are
marketed annually in North America and Europe, with
global production estimated at 800-1000 kg. About
30 000 kg of Taxusbiomass are required to produce 1 kg
of paclitaxel. Moreover, the world demand for groundhemlock
is increasing at 20% per year (Smith and
Cameron 2001), which will add pressure on the wild
stocks. The Eastern Canada Ground-Hemlock Working
Group (ECGHWG), composed of federal and provincial
forestry officials, private sector growers and harvesters,
and paclitaxel producers, is calling for the sustainable
management of the resource which has been threatened
by the lack of enforcement of proper harvesting
techniques.
The species initially harvested for production of paclitaxel
was western yew ( Taxus brevifolia) which, in Canada,
is found predominantly in British Columbia. Despite a
more efficient use of this species, overharvesting has
resulted in its serious reduction and in export restrictions.
Ground-hemlock found in provinces east of Saskatchewan
is increasingly coming under pressure as a source of
supply for the global paclitaxel industry. Current harvest
levels in Atlantic Canada are estimated at 3 million kg per
year of leaf and twig biomass, producing about 100 kg of
taxanes. Bioxel Pharma, a company operating in Quebec,
expects to eventually extract over 500 kg of taxanes annually,
valued at approximately $150 million, that will be
sufficient to treat about 300 000 patients (Fondation
de la faune du Québec 2004).
In response to rapidly increasing harvesting pressures,
the ECGHWG has established harvesting guidelines and
principles with corresponding criteria and indicators to
establish a sustainable ground-hemlock industry in Canada.
The harvesting principles include adherence to applicable
provincial and federal legislation, regulations, and
international treaties; conservation of biodiversity, soil,
and water on harvest sites; monitoring and tracking to
ensure that harvesting meets sustainability guidelines;
and access to information by harvesters and landowners
regarding the sustainable harvest of ground-hemlock
biomass. Research into methods of artificial propagation,
commercial-scale cultivation, and identification of better
strains of ground-hemlock is ongoing.
To demonstrate its commitment to the sustainable
management of this resource, Bioxel Pharma has created a
biodiversity fund, managed by the Fondation de la faune
du Québec, a nonprofit wildlife conservation group, to
support various research projects on ground-hemlock
and the wildlife that is associated with it.

Some NTFP have had a history of overharvesting
that provide valuable lessons for forest managers.
American ginseng
(Panax quinquefolius) is probably
one of the best-known examples of an NTFP that was
harvested nonsustainably for its highly valued medicinal
properties. Along-lived perennial, ginseng is now
an endangered species in Canada and exports of wild
ginseng are now prohibited. Despite being successfully
domesticated in Canada, generating exports of 2300 t
valued at $75 million in 2002, domestic sales of wild
ginseng are still taking place and wild populations
continue to decline. This is primarily due to the economic
value of wild ginseng that is ten times that of
domesticated ginseng because of its perceived superior
medicinal value (AAFC 2000). Species recovery activities
have already been implemented and wild ginseng is
now being marked to deter illegal harvesting.
Another cautionary tale is that of the pine mushroom
(Tricholoma magnivelare) in British Columbia that supports
an industry worth $20.7 million (Wills and
Lipsey 1999). It is an ectomycchorizal fungus that
depends on living, commercially viable conifer species,
making it imperative that its harvest be coordinated
with that of timber products. Unfortunately, the harvest
of pine mushrooms is often conducted in an unregulated
manner. As a result, government agencies have
little information about the volumes of mushrooms
being harvested in any particular area, or whether
questionable harvesting practices are being used. This
lack of information makes it difficult or impossible
for agencies to determine whether or not the resource
is being harvested sustainably and whether there are
any long-term implications for its rate of extraction.
Research is, however, shedding some light on the
biology of this mushroom. Researchers have identified
the ecological site conditions that this mushroom
prefers and inventories have been developed to
pinpoint potential pine mushroom habitat. Finally,
there have been trials to assess the impact of various
harvesting systems on mycorrhizal mushroom
production (Kriese 2000).
The case of ground-hemlock (see box) is proof
that it is possible to go from resource overharvesting
to a sustainable use that generates substantial
benefits.
