2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Assisted cork oak regeneration in the Sehoul forest, by acorn seeding and seedling plantation (derived from a plant nursery), involving careful husbandry and protection from grazing

2.2 Detailed description of the Technology

Description:

Because of the accelerated degradation of the Sehoul forest and the difficulties with natural regeneration, the Moroccan State has planned and adopted a policy, based on a global and integrated view. The preservation of forests is an important topic for socio-economic development. The National Plan for Reforestation defines the main lines of the national reforestation strategy and is the framework for the implementation of this technology.

The goal of this technology is to prepare plots where acorns should be sown or cork oak seedlings from plant nurseries planted. These test plots are guarded, maintained and watered to allow young plants to grow. Thus, cork oak regeneration ensures the continued existence and development of the forest. It conserves soil and water and fights against desertification. There are several benefits such as cork production, wood production, fodder production and better soil cover. Furthermore this technology positively impacts the socio-economic development of local populations, and services production (landscape, welfare and recreation) for urban populations.

The implementation of this technology needs the following activities: in general, good quality acorns and seedlings are required. Seedlings should come from the same region where they are planted and be certified by the authorities. An initial step in implementation is the clearing and shredding of small, woody plants. Soil preparation consists of 30 cm deep ploughing to loosen the topsoil, and to allow easier root growth. Then rows of pits are dug. Generally, it is crucial to apply correct plantation and seedling according to the season (winter), to ensure a depth of 50 cm in the planting hole, and to water copiously after planting to ensure a good contact between the soil and roots. A fence installed to protect areas from grazing is temporarily required until the trees are robust enough to cope with browsing cattle. The enclosure period usually lasts a minimum of 6 years.

The natural condition is semi-arid with precipitation ranging from 350 to 450 mm per year. The underlying geology consists of quartzite and sandstone, covered by marl. Soils are varied, but the main types are hydromorph and ferrous. Socially, the Sehoul forest is populated by poor farmers, strongly dependent on forest resources (fodder and firewood). The forest is owned by the government, but managed by local communities, who benefit from its use (marketing of cork, pharmaceutical products, charcoal, etc.). The rights of free forest exploitation for the local population are a political problem which needs to be resolved in order to achieve good forest management. Economically, the contribution of forestry to the GDP is low, but its environmental role is essential.

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the land user’s view How can they be overcome?
Forest users ask for subsidies in case of resting processes Define the beneficiaries for the forest exploitation and its rules, its calendar and its rest areas by founding associations and unions
For land users, the forest potential by pastoral activities needs to be improved by seeding of palatable species farmers must be included in the choice of implemented species
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view How can they be overcome?
Problems because of the high cost of this technology (about 8000 dh/ha, 1000 US$) Costs can be reduced if population commit to respect the converted plots, even without fences and guards.
