Rubare Forest Plantation

Rubare forest plantation/Reserve was selected and constituted by the German administration. The reserve was mapped by Herning in 1932 and by Pitt schenkle in 1934. It was resurveyed by the survey and inventory section of the Ministry of Natural Resources and Tourism in August 1995. Gazzettement was done as per Forest Ordinance schedule and was declared as a territorial Forest Reserve –Cap 132p.1398. Division of the Plantation
Rubare Forest Plantation is among the fifteen (15) plantations under Ministry of natural Resources and Tourism in Tanzania. Rubare Forest Reserve covers a total area of 6,374 Ha from two blocks (Kajunguti and Maruku). Kajunguti block Has 5,924 Ha, where by planted area is 570 Ha, expansion area to planted 1430 Ha, Natural forest, expansion area (not surveyed), riverline and swampy area covers 3924 Ha. Maruku block covers 450 Ha of which plantable area is 277 Ha, Natural forest, riverline, Rocky area and swampy covers 173 Ha. Legal status and ownership
Formerly the reserve was under the Native Authority (During the colonial administration). Later on it was taken over by West Lake Regional Authorities. The prime objective of establishing the reserve was to supply fuelwood and building materials such as poles, withies etc. to the inhabitants of Bukoba town. In 1958, the natural forest (except riverline forest) was cleared and as from 1959 up to 1968 planting of exotic trees species was at full swing. In 1975, the plantation was handed over to the Forest and Beekeeping Division as an eighteenth National Forest Project in the country.

1.2.2. Progress of the Plantation during the last Management Plan
The performance of the forest plantation for the last five years was good. However, the performance was affected by various challenges which include; inadequate forest staff to execute forest operations according to the APOs; obsolete and inadequate vehicles and machines (plants) for different operations; very high running and maintenance costs of old vehicles and machines; delay or failure to get trees seeds from Tree Seed Agency (TTSA); illegal grazing of livestock in the plantations and cutting of trees and lopping of cypress tops and branches for construction purposes. This has hindered the management to undertake most of the forest operations including road maintenance, patrol and general administration tasks and productivity of tree nurseries.

1.3 LAND

1.3.1 Area
The area available to Rubare Forest plantation/reserve is at least 450 ha out of which 285 are plantable. The remaining area forms part of riverine forests, valleys, rocks, glades and swamps/wetlands.

1.3.2 Topography
The topography of the area is rolling grassland (rweya) widely intersected by deep and broad valleys whose sides are fairly steep. The altitude is generally about 1300

In other words, the topography of Rubare Forest Reserve is determined by gently folded alternating layers of sandstones and shales. Where the sandstones reaches the surface, its layers stand out as rocky ridges (cuestas) with a steep, short slope on one side (face slope) and a long gentle slope on the other side (dip slope). The major sandstone ridges have a height of some 150-200m above the level of lake Victoria which is at an altitude of about 1140m. Where the shales are prevalent, uplands with short convex slopes have developed. As shales have lower porosity that sandstone and hence more run-off, a higher density of drainage lines is a characteristic of shales.

1.3.3 Geology and Soils
Geologically Rubare Forest Reserve which is part of Bukoba district is divided into three major formations which are ( a) sloping land e.g. hills,plateaus,escarpments etc. (b) lands and (c) erosional plains. Points (a)-(c) above are underlained by rocks of the precambrium era (order than 600million years. These rocks represent valleys with lacustrine sand deposits which are surrounded on both sides by massive outcropping of Bukoba sandstone which are fine to medium grained and light colours. Since all the materials of the Bukoban system has already gone through a weathering process and no new minerals were formed, some intrusions of volcanic rock in between the layers of the Bukoban sandstone forming sills and dykes of dolerite and gabbro which are moderately rich in ferromagnesium minerals are prevalent.
