Medicinal Tree Species Inventory in Aliko Dangote University of Science and Technology, Wudil, Kano-Nigeria

Abstract

Medicinal trees play a vital role in traditional healthcare systems, providing remedies for a wide range of human ailments. Despite their importance, the populations of these trees are increasingly threatened by deforestation, over-harvesting, urban expansion and climate change. Understanding the diversity, distribution, and utilization of medicinal trees is crucial for their conservation and sustainable use. This study aimed to investigate the medicinal inventory of tree species in Aliko Dangote University of Science and Technology (ADUSTECH), Wudil, Kano State, and assess their role in local healthcare practices. A survey research design was adopted for this study. The target population included all tree species within the ADUSTECH Wudil campus. Fifty (50) tree species were sampled. Data were collected through field observations and structured questionnaires and analyzed using frequency counts and simple percentages to determine the distribution, utilization and population status of medicinal tree species. The study documented a variety of medicinal tree species utilized in local healthcare practices. Community members exhibited extensive knowledge of the use and preparation of these trees. Certain plant families, notably Fabaceae, were dominant, while many other families were represented by only one or two species, indicating uneven distribution and ecological vulnerability. The study also found a significant decline in tree populations due to deforestation, over-harvesting, urban expansion, and climate-related factors. Medicinal trees are critical for local healthcare practices, yet their populations are declining, placing rare species at risk of extinction. Conservation and sustainable management strategies are essential to preserve these resources. The study recommends community-based programs, awareness campaigns, and training on sustainable harvesting, propagation, and preservation techniques to ensure the continued availability of medicinal trees.
