INTRODUCTION PREFACE This report is published with the permission of the Botswana Government but the views and opinions are those of the authors and do not necessarily represent those of the Government. Since the draft copy of the report was submitted to the Botswana Government in March 1967 there have been changes affecting the Northern State Lands. The export of live cattle from Ngamiland to Zambia via Kazengula has ceased and cattle are now taken to the Lobatsi abattoir via Francistown. The Chobe Game Reserve Boundary has been modified; the new boundary is shown on the Current Land Use map. Timber will not be extracted from within the Reserve.

ABSTRACT An investigation of the land resources of the Northern State Lands, Botswana, with a view to developing the cattle industry while conserving the game population, is described. The appraisal of resources is based on a survey of the physical environment, with special emphasis on the vegetation. An ecological survey was made of an area of 25 000 mi^ (64 750 km^); it consisted of a vegetation pattern analysis of air photographs and ground traverses covering 3 200 m (5 150 km). Sixteen vegetation communities are described and their distribution is shown on 1:500 000 scale map. Data on the soils and analyses of the herbage from certain areas are presented. The factors affecting the suitability of the land for ranching are discussed. Three areas selected for controlled development are described, but because of low carrying-capacity (1 adult equivalent to 25 acres/10 hectares) the economic returns are likely to be small. In six other areas development will depend on the availability of potable non-mineralised 'groundwater in sufficient quantity; economic considerations may limit the development of these areas. The abundance of game animals throughout the area is noted and their potential contribution to the economy is considered in terms of safari hunting, tourism, and game cropping. RESUME On a etudié les resources naturelles des Northern State Lands, Botswana, dans 1'intention de développeri1' industrie [bovine tout en conservant la population du gibier. L'evaluation des resources est basée sur un examen du milieu physique, avec une emphase speciale sur la vegetation. On a fait une etude écologique d'une superficie de 25 000 mi2 (64 750 km2), en analysant des photographies aériennes et en faisant des traverses sur le terrain. Seize populations végétales sont décrites et leur distribution est indiquee sur une carte a l'échelle 1:500 000. Les données sur les sols et 1'analyse de 1'herbage sont presentés pour certaines regions. On examine les facteurs qui influent sur 1'aptitude des terres pour l'élevage bovin. Trois regions choisies pour un développement controle sont décrites, mais ä cause de leur basse capacité de charge (25 ac (10 ha) par bete), le rendement économique sera limité. Dans six autres regions, la mise en valeur des terres dépendra de la quantité d'eau potable et non-mineralisée disponible; des considerations économiques pourraient limiter le développement de ces regions. (111126) 4 La region est giboyeuse. La contribution potentielle du gibier ä 1'économie est considérée en fonction.du safari, du tourisme et de la production de la viande.

Plants were subjected to 0.2%, 10%, 20%, 40%, 60% and 80% sea water dilutions (or 0.076, 3.8, 7.6, 15.2, 22.8, and 30.4 parts per thousand) for 11 weeks. Increase in salinity from 0.2% to 20% sea water had no effect on total dry biomass accumulation, while further increase in salinity to 80% sea water significantly decreased biomass by over 50%.

  • Elephant Social Dynamics, Spatial Ecology and Human Elephant Conflict in the Makgadikgadi Salt Pans and Kalahari Ecosystems
    Elephant Social Dynamics, Spatial Ecology and Human Elephant Conflict in the Makgadikgadi Salt Pans and Kalahari Ecosystems August 2009 Submitted to: Department of Wildlife and National Parks, Botswana Funded by: The San Diego Zoo and Elephants Without Borders Michael Chase Elephants Without Borders Po Box 682 Kasane Botswana Tel/Fax: ++267 6250202 Email: [email protected] PROJECT NARRATIVE Background Conservation management plans for wildlife species require accurate and reliable longitudinal information about population size, distribution, demography, reproductive rate and habitat use. However, obtaining detailed data is often hampered due to financial and time constraints imposed on local governments and scientists. Our fundamental aim in this segment of our elephant ecology study in the Kavango Zambezi TFCA is to augment the elephant conservation efforts of the Botswana Government by conducting research on the ecology of elephants in the Makgadikgadi and Kalahari ecosystems to identify factors regulating the spatiotemporal distribution and habitat use of elephants. Our ultimate goal is to share this information with appropriate authorities, communities and the scientific community, in order to mitigate Human Elephant Conflict (HEC) while simultaneously promoting the conservation of African elephants and their natural habitats in Botswana. Our study is unique and timely in that it monitors elephant range patterns in and out of national parks, across international boundaries and in habitats ranging from nearly desert to wetland/riverine environments. No other study has sought to conserve a “flagship” species by incorporating such a large and varied ecosystem. By adopting the most rigorous scientific methods and state-of- the- art techniques to derive estimates of elephant population size and distribution, as well as movement patterns across the region, we will greatly improve our understanding of the dynamic forces regulating elephant life histories, and their interactions with people thereby make significant contributions towards elephant conservation in Botswana.

    Mitt. Mus. Nat.kd. Berl., Geowiss. Reihe 5 (2002) 335-344 10.11.2002 Trifurcatia flabellata n. gen. n. sp., a putative monocotyledon angiosperm from the Lower Cretaceous Crato Formation (Brazil) Barbara Mohrl & Catarina Rydin2 With 4 figures Abstract The Lower Cretaceous Crato Formation (northeast Brazil) contains plant remains, here described as Trifurcatia flabellata n. gen. and n. sp., consisting of shoot fragments with jointed trifurcate axes, each axis bearing a single amplexicaul serrate leaf at the apex. The leaves show a flabellate acrodromous to parallelodromous venation pattern, with several primary, secondary and higher order cross-veins. This very unique fossil taxon shares many characters with monocots. However, this fossil taxon exhibits additional features which point to a partly reduced, and specialized plant, which probably enabled this plant to grow in (seasonally) dry, even salty environments. Key words: Plant fossils, Early Cretaceous, jointed axes, amplexicaul serrate leaves, Brazil. Zusammenfassung In der unterkretazischen Cratoformation (Nordostbrasilien) sind Pflanzenfossilien erhalten, die hier als Trifurcatia flabellata n. gen. n. sp. beschrieben werden. Sie bestehen aus trifurcaten Achsen, mit einem apikalen amplexicaulen facherfonnigen serra- ten Blatt. Diese Blatter zeigen eine flabellate bis acrodrorne-paralellodromeAderung mit Haupt- und Nebenadern und trans- versale Adern 3. Ordnung. Diese Merkmale sind typisch fiir Monocotyledone. Allerdings weist dieses Taxon einige Merkmale auf, die weder bei rezenten noch fossilen Monocotyledonen beobachtet werden. Sie miissen als besondere Anpassungen an einen (saisonal) trockenen und vielleicht iibersalzenen Lebensraum dieser Pflanze interpretiert werden. Schliisselworter: Pflanzenfossilien, Unterkreide, articulate Achsen, amplexicaul gezahnte Blatter, Brasilien. Introduction et al. 2000).

La réponse des graines au cours de la germination a été d’abord appréciée par application de quatre concentrations d’acide salicylique (0.25, 0.5, 0.75 et 1 mM) et de deux concentrations de chlorure de sodium (300 et 600 meq.l-1). Le traitement 0,5 mM AS a induit un taux de germination et une valeur germinative maximales des graines d’Atriplex halimus L., alors que pour les graines d’Atriplex canescens (Pursh) Nutt., le TGF et la VG sont nettement élevé respectivement sous l’effet de 1 mM d’AS et sous 0,75 mM l-1 d’AS.
