Assessment of Species Diversity and Forest Regeneration Potentiality in Buruku Forest Reserve, Kaduna State, Nigeria

Abstract

Species diversity and forest regeneration potentiality in Buruku Forest Reserve was assessed.  Four (4) plots (A–D) of 60 m x 60 m were laid in each plot. Point centred quadrant method of sampling was used. Transect were selected on pure random basis where data were collected on species diversity and families, density of woody stem, diameter class distribution, regeneration potentials and relative frequency. 21 families with a total of 135 species were obtained on the species diversity at Buruku Forest Reserve. The densities of woody plant varied between 434.03 - 771.60 per hectare in plots A, B, C and D. While the highest number of trees in diameter-class distribution were apportioned to 10 – 19 cm class interval in plots A, B, C and D respectively. Diameter class 50 cm and above had the lowest number of trees allocated to it. The regeneration potential of the diversified species was very poor, which has a great implication for regeneration and conservation of the various species encountered. Although Isoberlinia doka Craib & Stapf.     had the highest regeneration potential from each of the examined plots followed closely by    Acacia senegal, Parkia biglobosa and Terminalia avicennoides Gull & Peer. Important woody plants of economic importance, like Triplochiton scleroxylon K. Schum had zero regeneration potential. However, it is recommended that Buruku Forest Reserve Should be regenerated artificially (through enrichment planting, re-afforestation programme and so on) to increase the plant diversity in the forest and regeneration potentials of the species for sustainability of the forest reserve.
