RAJKARAN, A. (2011)

A status assessment of mangrove forests in South Africa and the utilization of mangroves at Mngazana Estuary.

Phil. II Diss. Nelson Mandela Universität, Port Elizabeth.

Abstract:

In South Africa mangrove forests are located in estuaries from Kosi Bay in KwaZulu-Natal (KZN) to Nahoon Estuary in the Eastern Cape. The aims of this study were to determine the present state of mangroves in KwaZulu-Natal, by assessing the current population structure, the changes in cover over time and associated anthropogenic pressures. A second objective of this study was to determine the effect of harvesting on the population structure and sediment characteristics in the Mngazana mangrove forest. To determine if harvesting was sustainable at Mngazana Estuary; the growth and mortality rates and associated growth conditions were measured. Finally by using population modelling sustainable harvesting limits were determined by predicting the change in population structure over time. The study focussed on the KwaZulu-Natal province as a fairly recent study addressed mangrove distribution and status in the Eastern Cape Province. A historical assessment of all mangroves forests in KwaZulu-Natal (KZN) revealed that the potential threats to mangroves in South Africa include; wood harvesting, altered water flow patterns coupled with salinity changes, prolonged closed-mouth conditions and subsequent changes to the intertidal habitat. As a result mangroves were completely lost from eleven estuaries in KZN between 1982 and 1999 and a further two estuaries by 2006. Mangroves only occurred in those estuaries where the mouth was open for more than 56 percent of the time with the exception of St Lucia, where the mouth has been closed for longer but the mangrove communities have persisted because the roots of the trees were not submerged. All mangrove forests in KZN were regenerating in terms of population structure as they had reverse J-shaped population curves as well as high adult: seedling ratios. Kosi Bay and Mhlathuze Estuary were two of the larger forests that showed signs of harvesting (presence of tree or branch stumps), but the greatest threat to smaller estuaries seems to be altered water flow patterns due to freshwater abstraction in the catchments and the change of land use from natural vegetation to sugar-cane plantations. These threats affect the hydrology of estuaries and the sediment characteristics (particle size, redox, pH, salinity, temperature) of the mangrove forests. The environmental conditions under which the mangrove forests currently exist were determined for five species. Lumnitzera racemosa and Ceriops tagal exhibited a narrow range of conditions as these species are only found at Kosi Bay, while Avicennia marina, Bruguiera gymnorrhiza and Rhizophora mucronata were found to exist under a wider range of conditions. The growth rate and response to environmental conditions of the three dominant species were important to determine as these species are impacted by harvesting. Mangrove growth rates were measured at Mngazana Estuary in the Eastern Cape, the third largest mangrove forest in South Africa. Areas of this estuary where mangroves harvesting has occurred, show significant differences in sediment characteristics as well as changes in population structure in harvested compared to non harvested sites. The growth rate (in terms of height) of Avicennia marina individuals increased from seedlings (0.31 cm month-1) to adults (1.2 cm month-1), while the growth of Bruguiera gymnorrhiza stabilised from a height of 150 cm at 0.65 cm month-1. The growth of Rhizophora mucronata peaked at 0.72 cm month-1 (height 151-250 cm) and then decreased to 0.4 cm month-1 for taller individuals. Increases in diameter at breast height (DBH) ranged between 0.7 and 2.3 mm month-1 for all species. Some environmental variables were found to be important drivers of growth and mortality of individuals less then 150 cm. A decrease in sediment pH significantly increased the mortality of Avicennia marina seedlings (0-50 cm) (r = - 0.71, p<0.05) and significantly decreased the growth of Rhizophora mucronata and Bruguiera gymnorrhiza seedlings (r = -0.8, r = 0.52 – p < 0.05 respectively). At Mngazana Estuary, mortality of this species showed a positive correlation with sediment moisture content indicating that this species prefers drier conditions. The density of Rhizophora mucronata was significantly correlated to porewater temperature in Northern KZN as was the growth of adult (>300 cm) Rhizophora trees at Mngazana Estuary. Mortality of Avicennia marina individuals (51-150 cm) was related to tree density indicating intraspecific competition and self thinning. Selective harvesting of particular size classes of Rhizophora mucronata was recorded when comparing length of harvested poles (~301 cm) and the size class distribution of individuals. Taking into account the differences in growth rate for each size class for this species it will take approximately 13 years to attain a height of 390 cm which is the height at which trees are selected for harvesting at this estuary. This is 2.6 times slower than those individuals growing in Kenya. The feasibility of harvesting is dependent on the growth rate of younger size classes to replace harvested trees as well as the rate of natural recruitment feeding into the population. Different harvesting intensity scenarios tested within a matrix model framework showed that limits should be set at 5 percent trees ha-1 year-1 to maintain seedling density at > 5 000 ha-1 for R. mucronata. However harvesting of Bruguiera gymnorrhiza should be stopped due to the low density of this species at Mngazana Estuary. Harvesting of the tallest trees of Avicennia marina can be maintained at levels less than 10 percent ha-1 year-1. Effective management of mangrove forests in South African is important to maintain the current state, function and diversity of these ecosystems. Management recommendations should begin with determining the freshwater requirements of the estuaries to maintain the mouth dynamics and biotic communities and deter the harvesting of (whole) adult trees particularly those species that do not coppice. Further management is needed to ensure that forests are cleared of pollutants (plastic and industrial), and any further developments near the mangroves should be minimized.

PAUW, A. & JOHNSON, S. (1999)

Table Mountain - A Natural History.

160 Seiten, mit Landkarten und zahlreichen Farbfotos.

Fernwood Press, Vlaeberg. ISBN 1-874950-43-1.

Vorwort:

The majestic profile of Table Mountain, flanked by Devil's Peak and Lion's Head, is one of the world's most famous landmarks. For many centuries it has been a source of almost mystical Inspiration for visitors to Cape Town. Even those who live and work in Its shadow every day, cannot help but feel its power. For those privileged to set foot on the sandstone slopes, a new world opens - a world even more awe-Inspiring than Table Mountain's famous profile. The Table Mountain chain is, above all, a living monument to the wonders of biodiversity -on a scale not seen elsewhere on this planet. One can only marvel at the celebration of life on the mountain, in all its glorious forms, and which have been so skilfully captured in the pages of this magnificent book. The authors, Anton Pauw and Steven Johnson, are two young scientists who have spent many years uncovering the secrets of Table Mountain. Not only have they both been recognised in academic circles for their ground-breaking work in the fields of animal-plant interaction and pollination biology, but both are also highly talented and accomplished nature photographers. This blend of experience, knowledge and creative skills has produced a truly unique work, a work that tells an exciting and very special story about a mountain where many thousands of life forms all have their place, all interdependent on each other for their common survival. As fascinating as this story is, there is more, for in its telling there Is the underlying message that sharing in this very special place on earth brings with it the responsibility for its conservation, a responsibility which rests not only with Capetonians, but also with the entire country and, indeed, the world. It is in this context that the Botanical Society of South Africa has decided to endorse this publication. It Is the first time that the Society, founded in 1913, has taken this step - the case for doing so was indeed a compelling one. I am greatly honoured to present this foreword in the conviction that past presidents of the Society who are no longer with us, namely, the late Sirs J.H. de Villiers and James Rose Innes, Messrs Duncan Baxter and Dudley D'Ewes, and Professors E.A.C.L.E. Schelpe and W.P.U. Jackson, would have looked favourably on the Council of 1999 who, on the eve of the new millennium, voted unanimously for the Botanical Society's official endorsement of this important publication. May this also be a source of inspiration to our 30 000 members worldwide, and indeed to every reader of this book, to make the transition from seeing ourselves not only as the current beneficiaries of the rich natural beauty of Table Mountain, but also as the active custodians of this treasure trove of botanical diversity.

Adv. Abri B. Meiring, President of the Botanical Society of South Africa

Endorsed by the botanical society of South Africa, this guide unveils the intricate relationships between plants and animals of Table Mountain.

MILLS, G & HES, L. (1999)

Säugetiere des Südlichen Afrikas - Eine illustrierte Enzyklopädie.

356 Seiten, farbig illustriert

Könemann Verlagsgesellschaft mbH, Köln. ISBN 3-8290-3610-8

Kundenrezension:

Vermutlich kostet dieses Buch in der südafrikanischen Orginialausgabe deutlich mehr. Dafür sprechen jedenfalls die hervorragenden Farbfotos und der sehr fundierte Text. Alle Säugetiere ab den Nordgrenzen Namibias und Simbabwes werden mit ausführlichen Texten und Verbreitungskarten behandelt. Nur einige besonders seltene oder unscheinbare Arten haben keine Fotos oder Farbbilder. Bestimmungsschlüssel oder Detailzeichnungen für die vielen Arten von Spitzmäusen, Nagetieren und Fledermäuse fehlen leider. Für das Freiland ist dieses großformatige Hochglanz-Buch aber ohnehin kaum geeignet.
Der Entschluß des deutschen Verlages irgendein schönes, buntes Buch für die preisgünstigen Auslagen auf dem Markt zu bringen, hat hier ein Angebot geschaffen, dass selbst Säugetierexperten nutzen sollten.
