Studies on Acacias in the Zaria Area of Kaduna State, Nigeria

A study of the floristic diversity of Acacia was conducted in the Zaira and its environs in Kaduna State with the objective of determining distribution and economic importance of members of the genus. Field surveys were undertaken to seven localities where samples of Acacia trees were collected and identified as described by D Oliver [1]. Random sampling technique was also used to interview 280 respondents from the localities using a check-list to collect information on uses of the trees by the local people. Additional information was collected using Focus Group Discussion (FGD) and In-depth Interview with Key Informants (IDI). Results revealed that in all, seven species namely Acacia albida, A. nilotica, A. seyal, A, sieberiana, A. senegal and A. auriculiformis were found in the study area. Members of the genus were reported to have a wide range of uses in industries as raw materials for medicinal products as well as food items for both man and animals. It was recommended that further research be carried out to ascertain the diversity of species and their economic uses.
