THE STATUS AND ECOLOGICAL IMPACTS OF CARISSA EDULIS IN OJU LOCAL GOVERNMENT AREA OF BENUE STATE, NIGERIA

Abstract

The classification of Carissa edulis as endangered plant species on the red list is not a good one for biodiversity and ecological sustainability. The abundance and ecological sustainability of Carissa edulis is highly necessary because it is not just of natural benefits but bountiful biological use and diverse ecological roles. The unique biological roles of C. edulis observed over the years triggered this study on the ascertainment of the abundance status of Carissa edulis among the Igede ethnic group in Oju Local Government Area of Benue State, Nigeria. The species data were collected from the indigenous people in April 2021 at the 2 major local markets; Onyike (Ihiejwo) and Obusa Markets in Oju LGA of the state. Cross sectional dataset were gathered by means of semi-structured questionnaires which were instantly administered arbitrarily to a large pool of knowledgeable subjects using the mother tongue. Pre-coded feedback of certainly or certainly not, open ended interview with each participant was carried out with allowance for possible additional information. Field information was obtained from 9 respondents from each of the 11 clans; 41 males and 58 females. The major demands captured in the questionnaire are; identification of the plant C. edulis called Utekwune in Igede dialect, its planting status, existence and abundance of the plant in the area before the study, existence and abundance of the plant in the area at the time of study, description of abundance with reference to time frame if ever in existence and diverse use of the plant. Data obtained were analyzed using descriptive statistics with the help of Microsoft Word 2010. Six clans reported rarity while five reported vary rare cases. Deliberate cultivation practice should be designed and implemented so as to increase its abundance out of the red List.
