Languages of publication
This study was used to assess the environmental tree species and their benefits in Kaduna Metropolis, Kaduna state. A total of one-hundred (100) questionnaires were randomly administered among four purposively selected four towns within the two major local governments in the study area. The two (2) towns having selected in the two Local Government Area were Angwa-Rimi and Kawo new extension in Kaduna North and Bar’nawa and Sabo respectively Kaduna South. Twenty five (25) questionnaires each were randomly distributed across age and sex in each of the four (4) selected towns while only ninety were retrieved for analysis. Data analysis was achieved through descriptive analysis which includes frequency distribution table and percentage and chart. Results show that majority of the respondents were aged between (21-30) and (31-40) years, these represent (44.4%) and (30.0%) respectively. They had secondary education (53.3%).Meliaceae occur most in all the identified families. The trees species identified in the study area include Eucalyptus spp, Azadiracta indica, Psidium guajava, Terminalia catapa, Mangifera indica, Anacardium occidentalis, Khaya senegalensis, Gmelina arboria, pinus spp, Carica papaya, Moringa olifera, Gliricidia sepium, Ficus spp, Afzelia spp, Balanite eagyptiaca, Borassus aethiopum, Persae americana, Polyantha longifolia etc. The following characteristics make these tree species the preferred environmental plants: Their fast growing ability, deep rooting pattern coppicing ability, ability to produce large crown size, tolerance to adverse weather condition, ability of trees to produce broad leaves for shade production, erosion protection, ability to provide fruits and their aesthetics and beautification values among others. In conclusion, urban tree planting is a potential strategy to ameliorate ecological and environmental menace; thus, there is need for the dwellers in the study area to intensify efforts towards planting tree around their houses, without this, the influx of people, urbanization as well as industrialization will create deleterious environmental hazard in the study area. It is recommended sensitization of the populace on the economic significance of urban trees particularly in combating environmental problems must be intensified.
