1. Aboveground production and growth dynamics of vascular bog plants in central Sweden
Sammanfattning : .... LÄS MER
2. Plant Population Dynamics of Dodonaea angustifolia and Olea europaea ssp. cuspidata in Dry Afromontane Forests of Ethiopia
Sammanfattning : Human disturbance has led to excessive deforestation and to a very limited forest cover in the Afromontane zone of Ethiopia, which forms a large part of the country. Thus urgent conservation measures are required to ameliorate the situation. LÄS MER
3. Studies on remnant Afromontane forests on the central plateau of Shewa, Ethiopia

4. Plant ecological studies related to restoration of a degraded ecosystem in central Tanzania
Sammanfattning : Kondoa Irangi area is among the most degraded ecosystems in Central Tanzania as a result of heavygrazing, fire, collection of fuelwood and improper cultivation practices. The restoration process of thisdegraded ecosystem through natural regeneration is slowed by the semi-arid climate of the area combinedwith poor soil nutrient status. LÄS MER
5. Seed dynamics and the ecological restoration of hill slopes of Kondoa Irangi, Central Tanzania
Sammanfattning : Improper agricultural practices such as bill slope cultivation, extensive clearing of vegetation using fire over a long period, and to some extent overgrazing have converted the once fertile hill slopes of Kondoa Irangi in central Tanzania into unproductive marginal land. It is 25 years now since reclamation measures were introduced to save the hills from further degradation, but the regeneration process, has been rather slow. LÄS MER
