Socio-economic and environment impacts on the utilisation of umSimbithi Tree (Milletia grandis) in Eastern Cape : a case study of Mt. Thesiger Forest, Pondoland.Obiri, John Angoro Festus. January 1997 (has links)
Wood products from Milletia grandis (E. Mey) skeels (umSimbithi), a prominent tree in the
coastal scarp forests ofPondoland, form an important economic base for the craft workers in
Urnzimvubu District ofthe Eastern Cape. The local carving industry draws considerable income
in a place where employment opportunities are scarce, poverty is rife and financial burden and
dependency is high. Despite the curio trade being perceived as important by the local
communities, little is known about this craft work industry or its impact on the forest especially
the sustainability of the wood resource base.
Resource availability and impacts of harvesting were assessed at Mount Thesiger Forest
Reserve (MTFR) through sampling plots and social surveys oflocal carvers and curio traders.
Stem size-class distributions ofstanding trees and stumps were used to investigate the present
quantity, past harvesting patterns and distribution ofM grandis within the forests. Line
transects sampling confirmed umSimbithi as a forest margin species penetrating to about 50
metres into the forest from the edge and its. current use was found to be unsustainable.
Current monitoring and management of most State forests in the Eastern Cape is inadequate,
and although a harvest ban has been served, it has only led to and encouraged poaching. Social
surveys indicated that the quality of monitoring and sustainability of wood stocks in the
Headmen forests appear better than in State forests and this raises hope for successful comanagement
structures in the area.
Craftwood production and derived income varied from one month to another depending on
wood availability, size and shape of stems, with straight stems being most preferred. MontWy
income per carver was estimated between R960 to RIIOO while the annual yield for the
estimated 100 carvers in the communities surrounding MTFR approximated RI.l million. It
was observed that higher sales could be obtained if (1) the amount of wood wasted during
harvests and carving could be minimised and (2) the craft products were marketed in the
lucrative up markets such as Johannesburg, Durban and Maseru.
Interviews with 30 carvers pointed to several problems most of them originating from the
stoppage of harvest permits following the ban on umSimbithi. Various recommendations
addressing carver's needs and promoting sustainable resource management are proposed.
These include (1) establishing an appropriate land tenure system, (2) reviewing the permit
system, (3) strengthening the institutional capacity ofthe Forest Department and (4) enhancing
efforts on community forest outreach through the extension system. Above all, and to achieve
sustainable forest management in Pondoland, tenurial rights needs to be addressed and the
options of co-management, community management and privatisation are discussed. It was
noted that for sustainable development to be realised in Pondoland, co-management ofnatural
resources is important and this must be supported by introduction ofother economic activities
that would alleviate pressure off the forests. / Thesis (M.Sc.)-University of Natal, Pietermaritzburg, 1997.

Resource quantification, use and sustainable management of coastal forests in the eastern Cape province.Obiri, John Angoro Festus. 17 December 2013 (has links)
Indigenous forests of South Africa are few, small in size and highly fragmented,
yet they face intense exploitation particularly in the rural areas. Management of these
forests is challenging. High rural dependency on forests and the need to ensure the
maintenance of the forest ecological processes that maintain biodiversity and ecosystem
integrity are at odds with one another. Rural needs from forests are mainly short-term
and interfere with the longer cycle of ecosystem maintenance. In Umzimvubu District
of Eastern Cape Province forest management through sustainable use is hampered by a
lack of information about the forests' ecology, resource availability and exploitation
patterns. Thus it is difficult to set quotas or sustainable harvesting levels. This study
addresses these challenges by tackling crosscutting themes of (1) forest policy and use,
(2) forest resource availability and exploitation and, (3) the ecological processes of
forest regeneration - all vital components for sustainable forest management.
Using questionnaires it was found that all forest stakeholders (i.e. forest
resource users and managers) were opposed to a ban on forest resource use but agreed
to regulated harvesting. Although the new forest policy advocates the devolution of
forest management from the state to communities, resource users preferred a greater
role for the state in forest management than expected. Given the choice stakeholders
selected state forest management over community forest management. However, the
combination of roles of the state and communities in forest management, as
exemplified by the new policy of participatory forest management (PFM) is probably
the most applicable management practice, although it is not without its problems.
Tree species are the focus of this study. Trees were largely used for fuelwood,
medicinal purposes, craftwork, fencing posts and building poles and involved twenty
species. Poles and posts were indiscriminately harvested from the medium (10-20cm
dbh) tree size-class. Fuelwood harvesting was selective and only certain species were
used. Fuelwood harvesting is unsustainable because the average amount of deadwood
produced by the forest marginally balanced that removed from forest as fuelwood.
Similarly medicinal tree harvesting (largely through stem debarking) was unsustainable
and at least 28% of the debarked trees died. Only one species (Macaranga capensis)
could withstand the current stem bark harvesting pressure.
Species suitable for pole and post harvesting were determined by a graphic
method, based on linear-programming approach that examined the spatial scale or grain
of regeneration of a species. The grain of a species is established by comparing the
density of stems from a species at the forest canopy and sub-canopy levels and
sanctions harvesting only if a species was adequately represented at both levels i.e.,
fine-grained. Only one species (Englerophytum natalense) met these requirements in all forests and could sustain high levels of pole and post exploitation. Harpephyllum
caffrum and Heywoodia lucens are among the most coarse-grained species and their use is discouraged.
A relatively high percentage of the forest is under gaps (7.8%) created via
natural disturbances of windthrow (50%), breaking tree branches (20%) and snags
(13%). Another 17% result from selective tree cutting activities. The gap-phase
dynamics paradigm appears to play a minor role in forest tree regeneration, as gap-size
niche-differentiation is weak and there is no gap-filling guild of pioneer species. A
lottery paradigm best explains tree regeneration in gaps in the forests of Umzimvubu
District. Although selective tree harvesting creates gaps, in moderation gap creation is
unlikely to change the forests' species composition since there is no gap-filling guild
that is favoured by gaps and recruitment is a chance event.
Resource use in the forests of Umzimvubu District is unsustainable and PFM
offers a viable option for managing these forests. Sustainable use of forest cannot be
achieved without an integration of the multifaceted social and ecological issues of
forest management and more importantly without prioritising and understanding the ecology of forests. / Thesis (Ph.D.)-University of Natal, Pietermaritzburg, 2002.
