Restoration buffer zone with indigenous species Kwaraguru estate Tanzania



The buffer zone around the reservoir dam in Kwaraguru was recently planted with Albizia versicolor, Dalbergia melanoxylon and Euphorbia candelabra. The species are indigenous and were used to create a link between a patch of forest near the tarmac road in which animals like Colobus monkeys live and the patches of forest towards the interior of the estate.

- Dalbergia melanoxylon (African blackwood, grenadilla, or mpingo) is a tree, native to seasonally dry regions of Africa. The tree is an important timber species for making musical instruments. Dalbergia is marked as ‘nearly threatened’ on the IUCN red list and all species from the Dalbergia genus are protected under CITES Appendix II, which means trade is restricted.
- Albizia versicolor (English: poison-pod albizia,large-leaved false thorn; Swahili: mnduruasi, mkenge, mchani-ndovu); Albizia versicolor is a deciduous tree up to 20 m tall and also native to the south-eastern part of Africa. It fixes nitrogen and does not have an invasive root system and can therefore be used in intercroppings. The beautiful termite-resistant wood is often used for making furniture, cabinets, parquet floors and as general timber woods on the farm and in the building trade.
- Euphorbia candelabra is a succulent species in the Euphorbiaceae family, commonly known as ‘candelabra tree’.

The planting was done in the rainy season, April 2018, in which 2,000 seedlings of Dalbergia melanoxylon and 1,200 seedlings of Albizia versicolor were planted in the area and also some branches of cactus (Euphorbia candelabra) were mixed in between. For accessibility all the grasses around the dam (60m both sides) were slashed manually with the Kwaraguru forestry team. Immediately after slashing the team started to mark planting spots by wooden pegs, the planting density is 3X3m. Since the area was not ploughed, the grasses around the pegs had to be removed by hoe, before planting. The total area of Mpingo (Dalbergia melanoxylon) at SFI Tanzania is now 4 hectares.
