Savannah vegetation under the microscope

Since the beginning of August, the botanist undertaking this work for GEPOG, accompanied by a paid worker, has been combing the savannah along the shore to determine exactly which spots to choose for more detailed study, within the framework of its map of the area. Areas where there are houses and gardens are excluded: their presence is evidence of how the natural environment has been altered since 2005, the date when the last detailed study was made, and complicating the task considerably.

At every chosen spot, the flora within a range of 100 metres is carefully searched for and identified. All the species present are noted on a dictaphone, and any unidentified plants are collected for further assessment.

At the same time the GEPOG worker records a number of different variables: the distance from the road and the nearest forest edge, evidence of fires, of grazing, of the soil having been turned, of paths, of the number of bushes and shrubs within a range of 100 metres … All the sites chosen are photographed and their position identified within a 100 metre circle drawn on paper.

In boots with water up to the knees, or breaking the sheets of solid sand hardened to a crust by the dry season which is in full swing, it needs between 5 and 8 hours a day to cover three recording points, bearing in mind the working conditions, particularly the ambient temperature. Thirty points must be chosen in each of three types of terrain, a total of 90 along the entire shore.

Equally, ornithological and soil-sample studies will have to begin soon.
