Deadwood (DW) is an important carbon component for conservation and management of biodiversity
resources. They are ubiquitous in many semi-arid ecosystems although its estimation is still posing lots of
challenges. At Chimwaga woodland in Dodoma Region of Central Tanzania, seasonal quantification of DW
produced by two Acacia spp. was done to evaluate the influence of each tree species, Dbh and canopy area on
DW biomass and to determine their ecological role in conservation of semi-arid ecosystem. Both purposive
and random sampling techniques were used in the course of a completely randomized design (CRD). Thirty
trees from each species of Acacia tortilis and Acacia nilotica were studied. Results portray that DW biomass
was significantly higher (P < 0.05) in the dry season than in the rain season whereby A. tortilis produced
669.0 ± 135.90kg DM/ha (dry season) and only 74.3 ± 135.90kg DM/ha (rain season) while A. nilotica
produced 426.1 ± 135.90kg DM/ha (dry season) and 36.5 ± 135.90kg DM/ha (rain season). DW biomass did
not correlate significantly (P > 0.05) with Dbh and canopy area. Inter-specific interactions were encountered
from experimental areas where DW was littered that facilitated ecosystem balance in semi-arid areas. This
information is important for estimating amount of dead wood biomass required to be retained in the forest
provided that, at the expense of ecology, they are refuge for arthropods, fungi, bryophytes and other important
soil microbes representing primary components of Biodiversity in semi-arid ecosystems. |
