This study aimed at generating data on Woody Species Diversity, Structure and Regenerationrnstatus of some species and was conducted in Yemrehane Kirstos Church Forest of Lasta Woreda,rnNorth Wollo Zone, Amhara Region, Ethiopia. Six transect lines were laid following altitudinalrngradient. Quadrats size of 20 m x20 m (400m2rn) were used to collect data that were establishedrnsystematically at every 100 m interval along the transect lines. Data on woody species wasrncollected from a total of 34 sampling plots of 400m2. To collect data on seedlings and saplings,rnfive subplots of 1 m x 1m (1m2) size located at the four corners and centre of the main plot werernused. Species diversity was determined using the Shannon Wiener index (H`). A total of 39 woodyrnspecies belonging to 38 genera and 28 families were identified in Yemrehane Kirstos ChurchrnForest. The overall Shannon-Wiener Diversity Index (H`) and evenness values for the entirernforest were 2.88 and 0.79, respectively. The six most abundant woody species in their order ofrnhighest density were Juniperus procera, Olea europaea subsp.cuspidata, Maytenus arbutifolia,rnOsyris quadripartita, Calpurnia aurea and Debregeasia saeneb. The densities for mature woodyrnspecies, saplings and seedlings were 506.6, 514.7 and 415.4 individuals ha-1 respectively. Thernbasal area of the forest is 72 m2 ha-1. The population structure and regeneration status of thernforest indicated that there have been high forest degradation and severe anthropogenicrndisturbances in the area and therefore, conservation of species, ecosystem restoration andrnsustainable use of the forest genetic resources are recommended as a result of this study.rnKey words: woody species, species diversity, regeneration, structure, species composition
