Title : UTILIZATION AND TRANSFER GUIDELINES OF FOREST GENETIC RESOURCES IN MOROCCO: BIOGEOGRAPHIC SYSTEM AS A STRATEGIC PROVENANCE DECISION-MAKING TOOL
Abstract : The assessment of Regions of Provenance (RoP) to preserve local gene pools and prevent mal-adapted genotype introduction is a relevant tool for the correct management of Forest Genetic Resources (FGR). However, there is limited knowledge of RoP in Morocco and no previous study has focused on theirs bioclimatic and physical characterization in detail. A study was carried out with the aim of characterizing RoP and analysing their bioclimatic and physical characteristics. Characterization of these areas is performed by biogeographic-based approach, where the elevation and area has been chosen as physical variables and six environmental variables was considered as bioclimatic variables (primarily related to temperature and precipitation). High-resolution gridded geospatial data and long-time-series climate dataset of a reference normal period 1960-1990 was used to analyse the homogeneity within and between RoP, through Geographic Information System (GIS). The results reveal that despite the intra-region ecological similarity of the 19 obtained RoP, some regions are relatively heterogeneous in terms of physical (elevation) and bioclimatic variable (temperature and precipitation). This finding has been particularly observed for RoP at a high altitude. Thus, in order to improve the intra-region environmental homogeneity, the interest of inclusion of elevation bands to the established RoP. The proposed biogeographic scheme can be considered a starting point for germplasm movement, and should be utilized in in combination with appropriate information on climatic suitability between donor origin and restoration site.
