Biodiversité et biomasse pyrophyte au Togo
Wildfires are an important ecological factor for the ecosystem lasting management. However, the lack of control over its management can lead to adverse effects on biodiversity and the ecological balance. Providing guidelines for efficient management of wildfires in Togo was the aim of this study foc...

Wildfires are an important ecological factor for the ecosystem lasting management. However, the lack of control over its management can lead to adverse effects on biodiversity and the ecological balance.

Phytosociological inventories were used to assess pyrophyte floras. Humid and dried fuel biomass were quantified based on 1062 samples within square of 1 m x 1 m. The pyrophyte flora identified was 466 species dominated by therophytes and Poaceae (40.48 %) which proportion vary according to the location and the ecological factors.
