Checklist of Tree and Shrub Species in Forests Across Anambra State Nigeria.

Abstract:

The evaluation of tree and shrub species in forests throughout Anambra State poses a significant challenge. Despite the importance of these forests in terms of ecology and biodiversity, there is a lack of comprehensive documentation on the various tree and shrub species found in the area. The absence of precise taxonomic information impedes conservation efforts, sustainable management, and well-informed decision-making regarding forest resources. This study was carried out to delineate the species of trees and shrubs present in some forest sites in Anambra State, Nigeria. Three tropical forests were selected from different zones of the study area based on their high floristic composition, they include: Unizik Conservation Forest Nnamdi Azikiwe University, Awka South (NACF), Ishigwu Forest, Umuomaku Orumba South (IFU), Umuikwu Forest, Anam Anambra West (UFA). A field inventory of trees and shrubs flora was adopted for data collection. On each location, six plots of 10 m × 10 m each were randomly demarcated following a line transect and trees within the plots were assessed. Identification and recording of different tree and shrub species was done by considering morphological features of leaves and stem. A total of 114 species belonging to 101 genera in 38 families were recorded across the three forests. The forests contained different proportions of unique species, indicating differences in species richness. It is recommended that habitat preservation be prioritized due to the wide variety of species observed in the three forests. Measures should be implemented to avoid deforestation, illegal logging, and land-use changes that could harm these ecosystems.
