This Study was conducted in Dilfaqar Regional Park which is found in Doddota-SirernDistrict, Arsi zone, Oromia Regional State with the aims to identify, describe thernvegetation type, species diversity, as well as the importance and impacts of socioeconomicrnactivities of the local people. Collection of vegetation data was made usingrnsystematic sampling methods, laying four transects and 41 plots. Plant specimens collectedrnfrom field were identified at the National Herbarium of Addis Ababa University. Socioâ€“rneconomic data was collected through formal and informal discussion based on PRArntechniques and semi-structured questionnaires. Vegetation data were analyzed using PCORDrncomputer software, whereas socio-economic data were analyzed using descriptivernstatistics. The vegetation in the study area was sparsely distributed, and only 39 woodyrnspecies representing 24 families were recorded. The most dominant species of thernvegetation in Dilfaqar Regional Park were acacia species; as a result vegetation of thernstudy area can be categorized under White (1983) as Somalia Massai Center of Endemism.rnClassification of the vegetation data resulted in four plant communities. The density ofrnwoody species was 1734ha-1. Beside this, the Shannon diversity index value was 2.877 andrnthe evenness value was 0.785. Currently Dilfaqar is recognized as one of the RegionalrnParks within Oromia Regional State, where many numbers of wild animal made thernenclosed area their habitat and rejuvenization of flora observed. About 95% of therninterviewed member of the local communities had positive attitude toward enclosure of thernarea as park. But, some landless householder consider enclosure of Dilfaqar as Regionalrnpark as the reason for the limited access for grazing and farm land. More over the elderrnmember of the local community were highly aware of the relationship betweenrnrehabilitation of forest and climatic change such as intensity of rain. The visibility ofrnwildlife and interest of the local people due to grass for house covering they obtain, willrnascertain the survival of the park. Since the area is highly degraded for along period ofrntime as a result the conservation activities of Dilfaqar Regional Park should involve therncollaboration of government, non governmental organizations as well as the localrncommunities to enhance eco-tourism, rehabilitation and sustainable utilization of thernresources in the study area.
