Developing needs-based inventory methods
for non timber forest products
Final proceedings
Executive summary
Recognising
the need for adequate NTFP inventory methods, the FRP decided to identify research
requirements in this area. A consultant, Dr Jenny Wong, was commissioned to
carry out a review of NTFP inventories and assess their biometric rigour (Wong,
2000) and to identify researchable constraints. Six general topic areas were
proposed for research (Annex 3). A special workshop was convened by the European
Tropical Forest Research Network (ETFRN) so that a wider group of specialists
and interest groups could consider these topics. The workshop was held at the
headquarters of FAO, Rome on 4-5th May 2000 (see Annex 1 for the agenda).
The workshop
was chaired by Jane Thornback and opened by Dr El Hadji Sene of FAO (see Annex
4). For the purposes of this workshop the term NTFP was used rather than the
FAO accepted term, ‘NWFP’ (non wood forest product). NTFP was defined as ‘all
products derived from biological resources found on forest land but not including
timber, fuelwood, lac or medicinal plants harvested as whole plants’ (Wong,
2000). Jenny Wong presented the findings of the methodological review which
covered close to 400 references, 97 of which described quantitative studies.
It was concluded that 38% of the quantitative studies reviewed used methodology
that could not be considered to be biometrically rigorous (Annex 5 and section
5.4 below). The review concluded that the principal difficulties with NTFP quantification
are:
- The variety of life
forms and distributions represented by NTFPs mean that traditional forest
inventory techniques cannot be adapted easily for NTFPs.
- There is a lack of
properly researched NTFP-specific sampling designs.
- There is little guidance
available on development of appropriate NTFP measurement (mensuration) techniques.
- There has been no application
to NTFPs of sampling designs tailored to monitoring needs.
- Lack of theoretical
models means that it is difficult to determine the sustainability of NTFP
harvesting.
- There has been little
application of novel sampling strategies to NTFPs
- There has been little
cross-disciplinary exchange of ideas and methods suitable for use with NTFPs.
- There is no service
that provides effective communication of advice to field workers and communities.
The workshop
largely accepted Dr Wong’s findings and moved on to examine the variety of information
requirements that might need to be met through NTFP inventory. Four presentations
were made illustrating needs in different contexts and at a range of scales
(see Annexes 6-9 and section 5.5 below):
- Participatory non-timber
forest product inventory in rural development forestry - Kathrin Schreckenberg,
Overseas Development Institute, London, UK.
- Natural Resource Monitoring
Concepts and Tools of Veld Products Research & Development -Mpho Mosate, Veld
Products Research and Development, Gabane, Botswana.
- Data needs for national
strategic planning and policy development - Paul Vantomme, FAO, Rome, Italy.
- Information for international
NTFP monitoring – with special reference to reporting on global forest resources
(FRA) - Peter Holmgren, FAO, Rome, Italy.
Plenary discussions
were held and covered the following topics (see section 5.6 below):
- Information needs
- Discussion of methodological
approaches to NTFP Inventory including:
- Multi-disciplinary
approaches
- Product specific
approaches
- The need for biometric
rigour
- Approaches at different
scales
- The FRA2000 approach
- The use of indigenous
knowledge
- Participatory approaches
The

following (see Annex 3 for details):

The workshop
concluded that these topic distinctions apply only at the species and product
level. Research requirements at the macro and community level are more focused
on the identification of information needs, the integration of methods (and
studies) to meet these needs and the development of appropriate indicators.
Participants
broke into three groups to discuss research needs in three different contexts/levels,
the species/product level, the community level and the national/international
or macro level. The research needs identified and the issues raised in groups
can be summarised as follows (see section 5.7 for a full account of group findings):
Group 1:
Species/product level research needs. It was agreed that greatest need in the
field is the determination of harvest levels. Therefore the research priority
is to develop inventory methods to assess the distribution and abundance of
NTFPs including the determination of growth and yield. Development of methods
should draw from existing methods in a variety of disciplines and from local
knowledge.
Group 2:
Community level NTFP assessment research needs. The Group decided that the priority
is to devise methods to bridge the gap between community inventory methods and
top-down (i.e. government, trade etc.) information demands. The biggest problem
is arriving at designs that both build on local knowledge, are intuitive to
local people and fulfill the information needs of strategic decision-makers.
Group 3:
Macro level research needs. The Group identified that it was perhaps logistically
desirable to undertake research on inventory and monitoring designs for particular
multi-species product groups. The biggest problem is developing the means to
amalgamate and verify data from many sources to give a macro-level overview
of NTFP utilisation.
Certain follow
up activities to the workshop were suggested (see section 7.2):
- Practical training
workshop. It was proposed that a workshop should be held in the field
involving some training in biometrically rigorous methods followed by an examination
of the practical problems of applying these.
- Biometrics hotline.
It was agreed that a biometrics hotline is needed or some service that could
provide field workers with practical and appropriate advice.
- Discussion group.
It was agreed that the existing email discussion group should be operational
over the next 2-3 months so that discussion can take forward the ideas developed
in this workshop.
- Improvement of
methods reporting.
A plea was made for adequate reporting of methods in published papers. It
was suggested that notices should be sent to journal editors requesting them
to ensure that methods are either reported adequately in the journal or that
the source of methods used are included in the references.
General
conclusions
- There is a need to
increase the awareness of the desirability of sound assessment of NTFP populations
and dynamics when considering utilisation of these resources.
- There is a need to
increase awareness of the importance of including biometric analyses in the
planning phase of any data collection exercise.
- Prior to identifying
gaps in methods it is important to identify information needs at different
levels. Discussion and agreement on needs at different levels is required
to ensure that research priorities identified in this workshop are correct.
- There is a clear expressed
need from field workers for NTFP inventory methods that are simple and easy
to use but at the same time are adequate for the determination of harvest
levels.
- Further work by inventory
specialists on the development of inventory methods and protocols for NTFPs
is required, drawing on methods that currently exist in a variety of disciplines.
- There is an urgent
need to provide advice on existing NTFP inventory and analysis methods to
field workers.
Additional outputs
of plenary sessions
- When undertaking an
inventory the issue of whom one is empowering with the resultant information
must be considered.
- There was no clear
conclusion drawn on whether it is better to take a product approach to NTFP
inventory methods development or to use the more generic approach suggested
in the review. Both have positive and negative aspects.
- Biometric rigour is
not needed in all cases and methods that are more ‘rough and ready’ should
also be developed.
- Utilisation of indigenous
knowledge as well as scientific knowledge is important. The linkages between
these are not straightforward and require further examination.
- Although full participation
of local communities in inventory is not always realistic this is important
because of the potential benefits that can be gained. Further work needs to
be undertaken on development of methods that can be used by communities.
- It was acknowledged
that in certain cases it is difficult to prioritise NTFPs for inclusion in
inventories and that there are no generic methods for doing this.
