Timber

• RIL and beyond…

+ Biodiversity

• Use ecology, life history, consider wildlife…

+ Non Timber Forest Products

• Trade-offs but possible

+ Ecosystem services

• Trade-offs but possible; appears in certification schemes (HCV); serious accountability issues…

+ Carbone

• Several risks, trade-offs and issues

…Against threats?

• Climate change, invasive species, land conversion….

The “Compatibility Continuum”

Inactive Active

Coincident

Timber management tools mitigates damage to other uses (roads, skid trails, timber inventorying)

Timber extraction benefits other values (logging gaps, directional felling)

Explicitly manage for both timber and NTFP values

Page 4: Can we manage forests for multiple uses in the Congo Basin?

Modes of Interaction

Independent (spatially segregated, or when there is no conflict of use for tree species with NTFP value)

Competitive—e.g., extraction of tree species with both NTFP value for different stakeholders or exclusion of a given group of stakeholders

Complementary—e.g., logging enhances growth/regeneration of NTFP (all else being equal)

Page 5: Can we manage forests for multiple uses in the Congo Basin?

Main Issues Many tropical tree species have both timber and

non-timber values that accrue to different stakeholders

Current certification schemes diverge for timber and NTFPs

Forestry education and training biased towards timber

Legal and regulatory frameworks dictated separately for timber and NTFPs

Best harvesting practices/management protocols for NTFPs have little validation

Selective logging in the Congo Basin

Timber remains the sole managed commodity

Highly selective, few individuals (less than 2) of few commercial species (less than 5) represent more than 75% of the volume harvested (less than 10m3/ha)

Rotation cycles of about 25-30 years; Minimum cutting diameter rules; No post-harvest silviculture

The area under proper management and certification is increasing

Impact of certification on harvest intensity

Cerutti et al. 2011

Certified concessions have a significantly reduced harvesting intensity

Pro-biodiversity activities in logging concessions

Only certified concessions show significant activities in favor of biodiversity

Estimates of the value of the bushmeat trade range from US$42 to US$205 million per year in West-Central Africa.

Current harvest in Central Africa alone may well be in excess of 5 million tons annually, could represent more than 20 million ha deforested for pasture!

30 to 80% of the protein intake of many rural populations

Bushmeat hunting in Congo Basin

Page 17: Can we manage forests for multiple uses in the Congo Basin?

Why a landscape approach?

High mobility of wildlife (migration, dispersal, extensive territories…)

Conserving Protected areas alone, will not be enough to conserve large sized/highly mobile species with huge ranges (e.g. Elephants) or locally rare plant species

The contribution of production forests to biodiversity conservation is increasingly recognized (e.g. North Congo where gorilla densities are higher in logging concessions than in the neighbouring NP)

New land-use types

Combine several land use types (e.g. logging concession, protected area, CBFM…) in one land-use management unit that would become an:

Realize the economic potential of the conservation side

Manage informal sectors like hunting, fishing or NTFP extraction for local livelihoods

Use part of the income generated by the industrial production side for the conservation area for reciprocal benefits

Foster certification (not limited to timber considerations)

Basic rules

Page 23: Can we manage forests for multiple uses in the Congo Basin?

Enabling conditions

Starting funds are needed to cover initial transaction costs

The willingness of the production sector to engage into certification or other biodiversity friendly practices

The willingness of the conservation community to collaborate, share experiences and support the private sector in integrating conservation concerns in management practices

A proactive political support (creating specific land-use units with specific instances for decision making) or, at least, neutral (no undue interference from the State).

Management principles

Maintain landscape heterogeneity Maintain large structurally complex patches of

natural vegetation Create buffers around sensitive areas Maintain or create corridors and stepping stones Use appropriate disturbance regimes in

management Maintain functional diversity Manage for keystone species Consider endemic, rare and threatened species

Page 26: Can we manage forests for multiple uses in the Congo Basin?

The Congo Basin has identified 12 Landscapes designed for shared production and conservation management of forests

Actors (public, private sectors) are aware about the necessity to improve collaboration for concerted or integrated management

But experiences at field level remain limited

Some implications for tropical forestry research

Page 28: Can we manage forests for multiple uses in the Congo Basin?

“Our major disciplines have long ago ceased to be effective as separate, have in fact

searched for ways of coming together…but are restrained by institutional resistance and

lack of vision” (Ron Burnett 2005)

Some final comments Search for a globally accepted definition of sustainable forest

management is pointless Management should be defined by societal demands Outcomes and results should be monitored based on agreed

objectives for management; unrealistic, unachievable or vague targets are of little use

Good management can never be attained through bureaucratic procedures alone.

Best practices require able and motivated managers are available on site to address concerns on a day-to-day basis: capacity building and training are keys!

Sound judgment remains the foundation of good management. Data can inform this judgment, but is not an end in itself

Page 32: Can we manage forests for multiple uses in the Congo Basin?

Search for universally agreed definitions is pointless (forests or sustainability)

Strive for continuous improvement to better outcomes when the “best” is unachievable

Scale research appropriately to the research question

Classical forest science has peaked! Grainger (2009) calls for a “new global forest science’” Burley (2004) believes that forest science can be

“restored” with “new interdisciplinary approaches that integrate the work of biophysical scientists and socio-economic researchers”
