Significant changes in the spatial expansion of cities in Nigeria have been observed from the turn of the new Millennium. In Minna, this fact is seen in many directions but in particular along the Minna-Bida Road Corridor. The corridor has witnessed major public and private sector developments since 2000. A special case along this corridor is that of Gidan Mangoro village. The village derived its name from mango trees which abound in the village. In addition are many other varieties of trees which together create a unique and unusual forest in a largely savannah environment. The objectives of this paper are to take inventory of the floral resources, investigate the floral diversity, examine its eco-economic services and interrogate the threat to this peri-urban ecosystem. Data for the study are based on Google Satellite Image, and direct data collection through observations and questionnaire administration. The results show loss in vegetation clusters at the rate of 10.6% per annum and growth in built-up area at the rate of 22.9% per annum. It is also shown that the factors of population, built up area, number of buildings and road networks are statistically significantly related to changes in clusters of trees on one hand and land area occupied by the trees, on the other. It is the belief of the paper that the floral resources of the village need protection in order to maximise their eco-economic benefits to the village and the larger urban system.
