Abstract
Study was conducted on Floristic Composition and Diversity of Tree Species in Kumo Town and its Environs. The aim was to investigate the Tree Species Structure, composition and diversity. Systematic random sampling method was used to sample the Tree species. The result showed that a total number of Twenty –Seven (27) species belonging to 8 genera and 12 families were identified. The family Leguminosae: Mimosoideae had the highest number of 4 species. The family Combretaceae, Moraceae, Caesalpinoidceae, and Palmae had 3 species each. The family Anacaediaceae, Myrtaceae, were represented by 2 species each. The remaining 5 families; Balanitaceae, Bombacaceae, Meliaceae, Rhamnaceae and Sterculiaceae were represented by 1 species each. The plant with the highest dominance was Adansonia digitata. The Shannon Weiner index was 2.45 and Simpson index was 0.48. This study therefore concluded that the species Azadirachta indica was the most abundant, with highest Relative Density, Relative Frequency, and Importance Value Index in the study area. This study recommended that the plants that had the lowest IVI such as Prosopis africana, Cassia sieberiana, need urgent conservation measures
Highlights
Tropical forests have the highest species-richness among the different ecosystems on the planet, and they are the most diverse land ecosystem facing pressures resulting from deforestation due to Agricultural expansion
The vegetation of Kumo Town, is under high biotic pressure due to collection of native plants the need to investigate the Floristic composition and diversity of woody species in Kumo town and its environs in order to understand the status of forest stands and diversity for conservation purposes
4.1.1 Composition of tree species identified at Kumo town and its Environ, Gombe State, Nigeria
Summary
Tropical forests have the highest species-richness among the different ecosystems on the planet, and they are the most diverse land ecosystem facing pressures resulting from deforestation due to Agricultural expansion. This is consistent with the works of Man from time immemorial has interacted negatively with his environment through his insatiable quest for food, shelter, energy and clothing among others This has resulted to environmental problems such as deforestation, desertification and pollution of various types and magnitude on global, national and regional scales. The vegetation of Kumo Town, is under high biotic pressure due to collection of native plants the need to investigate the Floristic composition and diversity of woody species in Kumo town and its environs in order to understand the status of forest stands and diversity for conservation purposes
