Woody Species Composition, Diversity, Structure and Uses of Selected Church Forests in Central Ethiopia

Seasonal variation in seed bank size and species composition of five selected habitat types within the Tembe Elephant Park. South Africa, was investigated. At three-month intervals, soil samples were randomly collected from five different habitat types: a, Licuati forest; b, Licuati thicket; c, a bare or sparsely vegetated zone surrounding the forest edge, referred to as the forest/grassland ecotone; d, grassland; and e, open woodland. Most species in the seed bank flora were either grasses, sedges, or forbs, with hardly any evidence of woody species. The Licuati forest and thicket soils produced the lowest seed densities in all seasons. Licuati forest and grassland seed banks showed a two-fold seasonal variation in size, those of the Licuati thicket and woodland a three-fold variation in size, whereas the forest/grassland ecotone maintained a relatively large seed bank all year round. The woodland seed bank had the highest species richness, whereas the Licuati forest and thicket soils were poor in species. Generally, it was found that the greatest correspondence in species composition was between the Licuati forest and thicket, as well as the forest/grassland ecotone and grassland seed bank floras.

Abstract Floristic diversity and the composition of vascular plants are described for the moist Afromontane forest (MAF) of Wondo Genet, south-central Ethiopia. A total of 75 (20 x 20 m) quadrats were sampled and data on species identity, abundance, elevation, slope and aspect were recorded. Different diversity indices and ordination techniques were used to analyze the data. A total of 240 plant species including seven endemic plant species were found representing 94 families and 210 genera, of which trees constitute 23.8%, shrubs 25%, herbs 35%, lianas 11.3% and ferns 5%. Cluster and indicator species analyses revealed five plant communities described as: Teclea nobilis-Calpurnia aurea, Erythrococca trichogyne-Millettia ferruginea, Croton macrostachyus-Vernonia hochstetteri, Protea gaguedi-Rhus retinorrhoea and Dodonaea angustifolia-Hypericum quartinianum. Elevation (R2=0.48, P<0.001), slope (R2=0.14, P<0.001) and aspect (R2=0.04, P<0.01) correlated significantly and negatively with species richness, whereas only elevation (R2=0.30, P<0.001) and slope (R2=0.13, P<0.001) related significantly and negatively with abundance. Sørensen’s similarity coefficient indicates that the forest of Wondo Genet is similar to moist montane forests of southwestern and southeastern Ethiopia. Given the high diversity, coupled with the existence of endemic species, ecosystem conservation and restoration strategies with further research are warranted.

Cutting Intensity

Second-growth, tolerant hardwood stands developed rapidly and, almost entirely from shade-tolerant advance growth, regardless of cutting intensity. Non-commercial woody species were seldom important competitors. Sugar maple, associated with beech on upland and balsam fir on lowland sites, was the dominant species. Yellow birch, basswood and hemlock, important contributors to wood volumes harvested, were minor components of second-growth stands. Valuable minor species such as red oak, white ash, and black cherry had practically disappeared. The application of known techniques for regenerating disturbance-dependent species is urgently required.
