Problématique de gestion durable de la biodiversité des bosquets sacrés de la Région des Savanes au Togo

الملخص EN

The present study is a contribution to the sustainable management of sacred groves of the region of Savannahs in Togo.

it had: (i) mapped the spatial distribution of sacred groves, (ii) characterize the floras of sacred groves.

sacred groves were previously identified with the help of prefectural heads of Environment services and local populations.

the floras characterization and the conservation status were achieved throughout on diversity and rarefaction indices, and species conservation status of UICN based on floristic and ecological inventories.

these inventories were coupled to inquiries of surrounding inhabitants on the importance and the management strategies.

the spatial distribution of sacred groves was mapped using the geographic coordinate recorded during field works.

globally, 170 plant species distributed into 112 genera and 37 families were identified.

the most represented families were: poaceae (8.93%), leguminosae-mimosoideae (8.33), combretaceae, and leguminosae-papilionoideae.

the investigate groves were discriminated into 2 super-groups: groves of azadirachta indica a.

juss.

and groves of diospyros mespiliformis hochst.

ex a.

rich.

almost half of species recorded have not been included in the IUCN Red List.

the rarefaction index shows 13 preferred species of studied BS.

an assessment of local biodiversity vulnerability of such groves could allow their integration into the national policy for the management of protected areas.
