TEREA is involved in the sustainable forest management of almost 4 million hectares of natural forests or plantations, and supports public and private sectors, offering expertise, technical assistance, consultancy and training.

From harvesting operations to the first or second transformation, our multidisciplinary team provides a complete expertise, including forest management technical aspects, social issues, economical constraints, and respect of the environment, eventually leading a forest or an environmental certification.

Sustainable forest Management inventories

Sustainable Forest Management (SFM) inventories are a multidisciplinary statistical evaluation aiming at quantifying, qualifying and locating forest resources such as timber and non-timber forest products, wildlife and human activities. 

Assessment of available volume

Knowing the available timber resource will help the forestry manager adapt his operating and transformation strategy, in order to find the balance between timber harvesting and the renewal forest resources (choice of the adapted minimum harvestable diameters for example).

Identification of zones of ecological interest

Botanical and wildlife data will help identify and locate rare, endemic, endangered or protected species in order to spot important areas for biodiversity conservation inside a forest concession.

Identification of anthropogenic utility zone

The compilation of indices linked to human activities, sacred or traditional-use places, combined with the distribution of non-timber forest products used by the local population (food, pharmacopoeia, craft products…) will allow to identify the important areas for the satisfaction of their basic and traditional needs, which will be confirmed later by extensive socio-economic studies.

These data will participate in the decision-making of the future land use of the forest concessions. They will enable defining and planning the activities in the production zone, conservation or protection zones and village-use zones.

TEREA has organized and supervised many SFM inventories over almost three million hectares of natural forests. Due to the experience acquired, the important data base collected and the in-house development of a software specialized in management inventories analysis, TEREA is a reference in Central Africa.

TEREA also proposes training sessions on exploration and exploitation forest inventories, and forest management inventories.

Preliminary assessments to sustainable forest management plans

To establish a forest management plan entails to carry out rigorous preliminary ecological and socio-economic assessments.

Dendrometric studies

The dendrometric studies complement the forest management inventories; it estimates the harvestable and marketable volumes from the inventoried trees, giving an image of the economic potential of the forest concession in order to adapt the industrial equipment to the timber resource.

Socio-economic assessment

To create a climate of trust between the forester, the village population and also the workers, the forest management plan must:

  • secure the rights and the livelihoods of the rural population living within or surrounding the concession,
  • take into account the rights and obligations of the workers and people living in the forest sites.

A socio-economic study, carried out through field surveys and village consultations, will help to better understand the village tenure, to review the social expectations of the population andto prepare reports of living conditions, health and safety, access to food and education of the workers and their beneficiaries.

Further studies 

The preparation of a management plan can be supplemented with other specific studies according to the socio-economic situation of the area to be managed. For example, an in-depth study of the local population, a market study, a detailed examination of the agricultural sector … could be necessary to create the forest management plan.

TEREA’s team, composed of forest engineers, environment engineers, timber engineers, sociologists, cartographers, and our partners and experts, can realize quality studies, which are necessary for a practical and suitable management plan.

Sustainable Forest Management Plan

A long-term forest operations planning

Made to last between 20 and 40 years, the management plan determines the rules to reach the social, environmental and economic objectives of the forest management, reconciling the sometimes divergent goals of the international community, the local communities, the State and the company.

Its aim is to implement a management which is socially beneficial, economically viable and ecologically sustainable. Once validated by the Administration in charge of the forests, the management plan represents the agreement between the company and the Forest Administration in terms of forest management.

Land Use zones’ delimitation

The management plan divides the forest area in « use zones », also called « series d’aménagement »:

  • The production “serie” is designed for sustained and sustainable timber supply. Activities are planned in the long-term and the operating rules aiming at minimizing the impacts of the production activities on the residual stand are defined,
  • The village-use “serie” is intended to bound current and future residential, cultivation and fallow areas, but also sacred and ”fordidden” forests as well as gathering areas,
  • The conservation or protection “series” have to be excluded from forest exploitation. These zones are composed of a range of sensitive environments (swamps, mountain forests) as well as « witness » habitats before exploitation.

Social and environmental action plan

As far as social aspects are concerned, the management plan settles the rights and obligations between the logger and the local population in order to maintain a sustainable social peace and a favourable socio-economic environment.

Some other rules are listed in the management plan, as hunt management, wearing of safety equipment, staff and its beneficiaries management (hygiene, education, health …), waste management...

TEREA has successfully assisted several forestry companies to prepare their management plan, some of which being pioneers in sustainable management in Central Africa.

With almost 4 million hectares of managed natural forests in Central Africa, TEREA has a recognized experience, allowing to assist the forest concessions managers to have an efficient management, environmentally friendly and sustainable.

TEREA has also developed its competences in the management of Eucalyptus plantations of Pointe-Noire (the largest planted forest area of Central Africa), taking into account the social and ecological issues. Thus, TEREA masters the whole industrial plantations’ development process and the certification guidelines application.

Management plan and long term sustainable management plan implementation

Development of management plans and annual operational plans

The 5-year management plan aims to define and plan the logging of a 5-year management unit as an implementation of the long term sustainable management plan

It defines the harvestable volume, the plan of the main harvesting roads of the units, the general organisation of the forest operations, the social measures and the measures to protect the environment to be implemented within the 5-year timeframe.

The annual operational plan determines the annual rules of the operational unit: the annual allowable cuts (AAC). It shows the results of the operational harvesting inventory that counts, identifies, marks and maps the trees for harvesting.

The implementation of the sustainable management plan comes with measures of reduced impact logging (RIL), in order to minimize the impact of forest operations on the environment.

TEREA assists many forest companies to implement their management plan, in making with them management documents, operational procedures, training sessions, and also assisting them to get certification. TEREA has a complete and diversified expertise, allowing to assist forest concessionaires with their particularities and know-how, in order to implement in an efficient way the various aspects of sustainable management in the field.

High Conservation Values

High Conservation Values (HCVs) is a concept that aims to improve the land-use planning systematically taking into account the ecological and social issues.

The identification of HCVs is an integral part of every land-use planning, and particularly within the framework of FSC or RSPO certification. It indicates, among other things, that the land-use planning in the HCVF must maintain or improve the characteristics of this kind of forests.

HCVs are identified and analyzed, and conservation measures are proposed in order to guarantee their integrity. To identify HCVs, we need to study the biodiversity, the integration of the area concerned in the landscape or ecoregion, the ecological issue and the cultural identity of the local population.

By socio-economic studies, biodiversity inventories, mapping studies and bibliographical studies, TEREA works in the field of HCVF for industrial plantations and forest concessions in tropical zones. Then, TEREA proposes provisional measures in order to ensure the development of ecosystems and prevent the cultural and socio-economic erosionof the population concerned.

Traceability and chain of custody

Developing a chain of custody within a company allows to guarantee the origin of the raw materials of the processed products.It is based on supply chain expertise, log tracking in the industrial installations and finished or semi-finished products’ marketing control. It allows to propose certified products in the market.

TEREA assists forest companies and processing industries to comply with certification obligations (FSC, legality certificates as OLB or TLTV, PAFC, PEFC…). According to your supplies, your markets and your processing methods, TEREA can give you consultancy to choose your certification systems, the log tracking to be implemented, your supplies and also in your communication.

TEREA can assist you until the certification audits, and can organize training sessions and awareness actions for your staff, in order to obtain the certification.
