Floristic structure and phytosanitary condition of woody species in Razoutenga forest in Burkina Faso
- Biodiversity Journal : 1-8
Résumé
This study analyses the floristic composition and phytosanitary condition of woody species in Razoutenga forest, Burkina Faso. Using 20 randomly placed circular plots (1250 m2 each), research-ers inventoried trees ≥15 cm in diameter across 2.5 ha. The forest hosts 71 woody species from 18 genera and 9 families, with Mimosaceae, Combretaceae and Anacardiaceae being most abundant. Health assessments show 92.95% of trees are defect-free, with no desiccated crowns or dead specimens. Regeneration includes 137 juvenile plants in 20 genera. While species diversity is moderate and locally adapted, signs of anthropogenic degradation are evident. Sustainable management is urgently needed to conserve biodiversity and restore ecosystem integrity.
