MEDICINAL PLANTS IN WALES; HISTORIC PERSPECTIVE AND CURRENT DEVELOPMENTS
Man's earliest association with wild plants was the recognition that in addition
to their use as hunting and 'warrior' poisons they could also be used to alleviate
sickness and bodily afflictions. The knowledge base was called 'wortcunning' and
in all cultures it was passed from generation to generation. It is estimated that
over 4,000 species of medicinal plants are used throughout the world, either as herbal
remedies or as the source of phytopharmaceuticals. Currently 40% of prescription
drugs owe their origin to phytochemical compounds. Pharmacological advances in analgesics,
steroid therapy, antineoplastic agents, antihypertensives, anti-arrythmic agents
and others were initiated by the observed bioactivity of plant constituents thus
emphasizing the need to sustain and conserve both those species with known medicinal
value and the 80% of species still to be investigated. The twelfth century Physicians
of Mydffai practising in Central Wales left a written record of their remedies with
formulations. These and other historical texts are being examined for evidence of
their possible use in contemporary medicine. The Welsh National Botanic Garden is
currently initiating a research programme on the Mydffai remedies with particular
emphasis on sustained use and conservation of plant species with clinical potential.

CULTURAL KEYSTONE SPECIES: IMPLICATIONS FOR ECOLOGICAL CONSERVATION AND RESTORATION
Ecologists have long recognized that some species, by virtue of the key roles they
play in the overall structure and functioning of an ecosystem, are essential to its
integrity. Similarly, in human cultures everywhere, there are species that form the
contextual underpinnings of a culture, as reflected in their fundamental roles in
diet, as materials, or in medicine. These species often also feature prominently
in a people’s language, ceremonies and narratives and as cultural icons. Without
certain key species, a culture itself would be completely different. An obvious example
is western red-cedar (Thuja plicata) for Northwest Coast cultures of North
America. These cultural keystone species are often also a prominent element of local
ecosystems and may be harvested in large quantities, and intensively managed for
quality and productivity. Given that biological conservation and ecological restoration
embrace human cultures as integral ecosystem components, one approach that may contribute
to success in research projects is to recognize and include such cultural keystone
species in project design. In this paper, we explore the concept of cultural keystone
species and present examples from First Nations cultures of British Columbia, Canada.

A THORNY ISSUE: DEVIL’S CLUB (OPLOPANAX HORRIDUS) COMMODIFICATION, CONSERVATION
& CULTURAL KNOWLEDGE
A growing consumer preference for traditional herbal medicines presents indigenous
peoples with opportunities for wider recognition of their traditional knowledge systems
and local economic development. However, there are many unresolved issues associated
with commercialization of local products and associated knowledge. Increased harvesting
and commercial sale of devil’s club (Oplopanax horridus; Araliaceae), one
of the most culturally important plants for indigenous peoples living within its
range in northwestern North America, raises concerns that over-harvesting may lead
to population declines, and that commercial use without protection and compensation
for traditional medicinal knowledge associated with this species is inappropriate.
Data from devil’s club experimental harvesting indicates that intense commercial
harvesting practices, in which large portions of decumbent stem and roots are removed,
deplete the vegetative bud bank, hindering regeneration and recruitment, and potentially
preventing long-term population persistence. Surveys of cultural knowledge associated
with devil’s club and data from experimental harvesting trials emulating several
traditional harvesting practices suggest that traditional harvesting methods can
potentially aid in the development of sustainable management guidelines. However,
the depth of the cultural significance of this plant, evidenced by data on traditional
use, make it unlikely that commercialization is compatible with its cultural significance.

ECOLOGICAL SUSTAINABILITY AND MANAGEMENT OF HIGHLY THREATENED MEDICINAL PLANTS IN
THE NEPAL HIMALAYA
Medicinal and aromatic plants (MAPs) in the Himalayas are highly threatened due to
overexploitation. Scientific information regarding their sustainable utilization
is greatly lacking. Since 1997, through an applied ethnobotanical project, we have
focused on two aspects for the management of MAPs in northwest Nepal, i) monitoring
population dynamics and simulating harvesting impacts of two highly threatened clonal
species, viz., Nardostachys grandiflora (jatamansi) and Neopicrorhiza
scrophulariiflora (kutki), and ii) understanding ethnoecological knowledge on
resource use and management. Populations of MAPs were monitored in 400 plots (1m
x 1m) in nine different sites of alpine pastures along harvesting gradients. Populations
of both species were dominated by regeneration of ramets through vegetative means.
Negative correlations were found on ramet recruitment and survivorship with harvesting
intensities. Kutki showed rapid and successful multiplication and recovery
of ramet than jatamansi. It is revealed that jatamansi is more vulnerable
to harvesting than kutki, due to its different morphology and low reproductive
success. Ethnoecological study revealed rich knowledge of people in terms of classification,
use and management of resources. Specifically healers have adopted harvesting practices
based on understanding of plant’s biology and ecology. The use of such knowledge
will be valuable for developing management guidelines for Himalayan MAPs.

BWINDI’S HERBALISTS (UGANDA): WHAT DO THEY COLLECT AND WHERE?
Closure of the Bwindi Impenetrable Forest, a national park and World Heritage site,
to traditional medical practitioners created major conflict between the conservation
community and local residents. The level of conflict and the amount of active damage
to the park resulted in the introduction of multiple-use zones, from which registered
users, including herbalists, would be allowed to harvest limited amounts of specified
resources. This study compared four categories of medicinal plant users: traditional
birth attendants, women general herbalists, male herbalists and male non-specialists.
From each of the 100 interviewees, information about the plants collected, parts
used, and their habitats were recorded. More than two-thirds of the 295 herbs or
shrubs listed grow outside the protected area. Most plants were used in mixtures
with leaves the most commonly used plant part. Men generally collected most medicinal
resources from the forest and often used roots and bark while women relied on fallows
and secondary bushland to collect mostly leaf material. Harvesting often requires
the performance of certain rituals, which limit resource offtake and protect the
resource. The findings suggest that the ‘no use’ approach does not benefit conservation
in the long run as it creates local opposition against the protected area.

CONFLICT, CONSERVATION AND COMPLEXITY: REVIEWING MULTIPLE-USE ZONE IMPLEMENTATION
AROUND BWINDI-IMPENETRABLE NATIONAL PARK, UGANDA, 1991-2001.
Located in the densely populated landscape of southwestern Uganda, this 330km2 forest
has been a focus of international conservation efforts as it provides one of the
last refuges for half the world’s mountain gorilla population. This paper reviews
an attempt to address the conflict between the surrounding local community and conservation
of Bwindi-Impenetrable National Park (BINP), which followed its gazettement as a
national park in 1991 from its earlier status as a forest reserve for over half a
century. The multiple of local resource users surrounding the national park are only
one layer of complexity which face implementation of measures to reduce conflict
between local people and this conservation area. Rapid senior staff turnover amongst
park wardens, changes in policy regarding benefit sharing and changes of emphasis
with shifting roles between international conservation and development agencies have
all added to the challenge of trying to implement multiple-use zoning. Local community
involvement in conservation initiatives varies widely according to local circumstances
and according to the views of those involved in designing and implementing such initiatives.
In conclusion, this paper synthesizes what lessons were learned in this process and
the type of pitfalls that could have been avoided along the way.

APPLYING FOREST STEWARDSHIP COUNCIL CERTIFICATION TO KENYAN WOODCARVINGS: OPPORTUNITIES
AND CONSTRAINTS
The Kenyan woodcarving industry employs up to 80,000 carvers with 350,000 dependants
and generates c. US $21 million per year. However, dwindling hardwood resources are
now putting livelihoods at risk and the cutting of c. 50,000 trees per year for carving
alone contributes to the degradation of globally important, biodiversity-rich East
African forests. Meanwhile, carvers have found alternatives in exotic species such
as neem (Azadirachta indica) and jacaranda (Jacaranda mimosifolia)
are abundant and produce fine carvings. People and Plants has advocated switching
to these ‘Good Wood’ species, to carvers, tourists and importers, believing that
strong market-led demand for ‘Good Wood’ carvings can change carver’s practices.
Obtaining certification from Forest Stewardship Council (FSC) could prove a pivotal
tool in increasing economic incentives to carvers and offering consumers a clearly
recognizable ethical choice, whilst reducing the impact on threatened Kenyan forests.
Substantial barriers still need to be overcome for the pilot case of neem, produced
on small-holder farms, in the coastal Malindi District, to be certifiable. If successful,
however, this case has great potential to set a precedence for sustainable woodcarving
and certification in Kenya and globally. This paper highlights the opportunities
and current constraints of applying FSC certification to Kenyan woodcarving.

FROM TAXUS TO TRILLIUM: THE COLLECTION AND USE OF NATIVE PLANTS IN
THE NORTHWESTERN US
Wild plants in the northwestern region of the U.S. contribute to floral, woodcraft
decorative, medicinal, and natural foods markets where Internet commerce has made
these products available to consumers worldwide. New immigration into the region
of various ethnic groups, and perceptions of economic opportunity and plentiful resources
have increased the number and kinds of wild plants harvested. Much of this harvest
occurs on public lands with relatively little inventory, monitoring, or effective
oversight. A broad approach was applied in developing information that provides a
practical knowledge and understanding of these species. We first developed an inventory
of commercially wild-harvested plants, then gathered and validated a wide range of
information about these species. A literature search, along with interviews and meetings
with harvesters, tribal people and managers resulted in descriptions of biological
and ecological attributes of over 70 plants and fungi, wild harvest methods with
alternatives to wild harvest, and their primary uses. We applied a set of criteria
in identifying species vulnerable to harvest and reported areas of concern with regard
to species conservation and importance to indigenous peoples. We found that most
species can be cultivated, which has implications for managing these species in their
native habitat.

DOCUMENTING AND PROMOTING SUSTAINABLE HARVESTS OF WILD FOODS, MEDICINES AND BASKETRY
MATERIALS: ECO-LABELS AND INDIGENOUS PARA-ECOLOGISTS
We report on efforts in the arid lands of the USA and Mexico to provide new income
to remote rural communities of indigenous peoples through promoting the sustainable
use of wild land plants for local and regional markets. We will present public opinion
surveys of what attracts consumers to purchase such products for elevated prices
compared to non-certified products, which may cause more ecological damage. In particular,
we propose 1.) Training indigenous para-ecologists to monitor and evaluate harvesting
impacts and 2.) Using eco-labels to distinguish a market niche for each certifiably
sustainable product. A case study involving the Seri Indians of Mexico exemplifies
the benefits to indigenous communities for such involvement.
