Inventory of wild mushrooms in Miombo woodlands in Western Tanzania; assessment of marketing potential of wild mushrooms.
Article
Mass population displacements put additional stress on the ecosystems and often lead to conflicts with the host communities, especially in the case of large refugee or Internally Displaced Person (IDP) camps. Therefore, there is need for the assessment of environmental impacts and, based on this, the sustainable management of natural resources betw...
Article

Despite their socio-economic importance, forests and other woodland vegetation are declining rapidly in Africa. In the Sahel, climate change and desertification intensify this problem and the local population is lacking woodland resources for daily life. Therefore, there is a need for improved and long-term restoration of degraded ecosystems. The p...

A forest mapping and inventory has been recommended for the Sudanese refugee hosting areas in Maban County (Upper Nile) and Pariang County (Unity States) by both, the multi-party rapid environmental assessment in November 2012 and UNHCR’s environmental inception mission in June 2013. The aim of the forest mapping/inventory is to estimate the total...

A forest mapping and inventory, as part of the environmental action plan, has been recommended for the Sudanese refugee hosting areas in Maban County (Upper Nile) and Pariang County (Unity States) by both, the multi-party rapid environmental assessment in November 2012 and UNHCR’s environmental inception mission in June 2013. The reporting from the...

Aim: The spatio-temporal dynamics of dry evergreen forest patches in the savanna biome of the Kagera region (north-western Tanzania) are largely unknown owing to a lack of pollen and macrofossil evidence. Our aims were to reconstruct local-scale shifts of the forest–savanna boundary in order to determine whether the forests have been expanding or r...

Article
Full-text available
Forest and woodland ecosystems in Tanzania occupy more than 45% of the land area, more than two thirds of which made up of the Miombo woodland. The main form of land use in the Miombo region has long been shifting and small-scale sedentary cultivation. The lack of infrastructure and prevalence of deadly diseases such as malaria and trypanosiomiasis...

Book
Cet ouvrage fournit de multiples informations sur la botanique et l’écologie forestière de toutes les plantes ligneuses du Rwanda, et met en avant le riche savoir traditionnel des communautés rwandaises sur l’usage de ces espèces. Plus de 540 espèces, sur les 888 plantes ligneuses traitées dans ce livre, sont illustrées par une iconographie remarqu...
Article
Question: What are the genesis and development of thicket clumps within a savanna landscape at geomorphically different locations and what are the driving forces?Location: The Kagera Region, in the border area of Rwanda, Uganda and Tanzania.Methods: The vegetation of 32 dry evergreen thicket clumps and their surrounding savannas have been analysed...
Article
Full-text available
The Selous-Niassa miombo woodlands of southern Tanzania and northern Mozambique are one of the largest and for the global biodiversity most significant, trans-boundary natural ecosystem in Africa, covering over 154,000 km2. The Selous-Niassa Wildlife Corridor serves as migratory route between the Selous and the Niassa Game Reserves hosting the worl...
Technical Report
Full-text available
A first vegetation study has been carried out in the Selous-Niassa Wildlife Corridor from 12 to 26 September 2006 focussing on potential plant biodiversity hotspots, i.e. vegetation formations along watercourses, in swampy areas, on rock outcrops or other arid areas. Two major ecosystems occur within the Corridor: the miombo woodland and the savann...
Article
Full-text available
Twenty-four small coastal forests within the Saadani National Park have been surveyed. According to their topographic position different types have been defined, i.e., small hilltop forest on hillock, gully forest, forest patch/thicket clump, groundwater forest, gallery forest and large hilltop forest. Their floristic composition is analysed and th...
Technical Report

Article
Full-text available
The enormous wood requirements of about 450 000 Rwandan refugees in northwestern Tanzania led to the depletion of the wood resources in the surrounding savannas in an area of about 500 km2 . The natural regenera- tion of the woody plants was endangered by frequent fierce late dry-season fires. Since total fire exclusion of the vast area was not fea...
Article
The possible use of fire for the management of the Ankarafantsika Reserve in the northwest of Madagascar and of its surrounding area is studied. Within this savanna landscape large parts of the remaining dry forests still exist with a unique biotic diversity, both in terms of total number of species and endemism. Unfortunately, mainly man-induced u...
