Selective logging in the congo basin

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

Certified concessions have a significantly reduced harvesting intensity

Pro-biodiversity activities in logging concessions

Only certified concessions show significant activities in favor of biodiversity

Basic intentions, Limited results

Activities limited to legal requirement

Managing for timber and wildlife

Managing for timber and wildlife


Bushmeat hunting in congo basin

Bushmeat hunting in Congo Basin

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

Barriers and solutions

Barriers and solutions


Beyond boundaries landscape scale considerations

Beyond boundaries: Landscape scale considerations


Can we manage for timber and biodiversity 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)

Protected areas and logging concessions : surprisingly close neighbors

National Parks

Logging Concessions

Hunting areas

Parks, Concessions, Hunting areas : where are flagship species ?

Some surprising assessments

Number of ape nests/km2

Integrated production conservation territory

Integrated production / conservation territory

Combine (at least) two major land use types (e.g. a logging concession and a protected area)

with community-based managed areas

in one land-use management unit that could become an integrated production/conservation landscape

Basic rules

Basic rules

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)


Enabling conditions

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).


Can we manage for timber and biodiversity 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

To conclude

To conclude…

We believe that management for both timber and biodiversity is possible in the Congo but it requires new thinking in terms of land-use types and stronger private–public partnerships associating production and conservation parts of the landscape and a renewed long-term support from the international donor

community.
