Four species of Sunbird commonly occur in the valley of the gularis,Chania atSharpe,South Kinangop.the KenyaTheseMalachiteare NectariniaSunbird;famosaNectariniaaenei• tacazze (Stanley), the Tacazze Sunbird; Drepanorhynchus reiche• nowi, Fischer, the Golden-winged Sunbird; and Cinnyris medio• cris mediocris, Shelley,. the Kenya Double-collared Sunbird. The association of these four species was observed long ago by Sir Frederick Jackson (vide what is unquestionably an original note. of his in the recently-published "Birds of Kenya and Uganda," edited by W. L. Sclater, at page 1342 in the third volume). So far, during a residence of nearly twelve months on the Kinangop, I have not met with the Bronzy Sunbird (N. kili• mensis kilimensis, Shelley) which might be expected to occur and has been taken as near as Limoru at an altitude not more than 1,500 feet below us, but which I think must be regarded as definitely a: bird of, in these parts at least, lower altitudes than the Kinangop Plateau; and another species not yet noted is the Scarlet-tufted Malachite Sunbird (Nectarinia johnstoni johnstoni, Shelley) which though quoted by Sclater as occurring on Kilima• njaro and Kenya Mountains only, certainly is found as well on the higher parts of the Aberdares; and, as I am informed by Dr. van Someren, has once been noted on Major Ward's estate which is at much the same level as the main run of the Kinangop close in to the mountain, i.e. about 8,500 feet above the sea. It woold doubtless be an occasional visitor only from the higher levels.

The present geological period has more species than any other, yet the current rate of extinction of species is greater now than at any time in the past. Ecosystems and communities are being degraded and destroyed, and species are being driven to extinction. The species that persist are losing genetic variation as the number of individuals in populations shrinks, unique populations and subspecies are destroyed, and remaining populations become increasingly isolated from one another. The cause of this loss of biological diversity at all levels is the range of human activity that alters and destroys natural habitats to suit human needs.” (Primack, 2002). CapeNature launched its State of Biodiversity Programme (SoBP) to assess and monitor the state of biodiversity in the Western Cape in 1999. This programme delivered its first report in 2002 and these reports are updated every five years. The current report (2007) reports on the changes to the state of vertebrate biodiversity and land under conservation usage.

A sexually dimorphic ungulate of large stature and unique coloration, it is the only species in the genus Boselaphus. It is endemic to peninsular India and small parts of Pakistan and Nepal, has been extirpated from Bangladesh, and has been introduced in the United States (Texas), Mexico, South Africa, and Italy. It prefers open grassland and savannas and locally is a significant agricultural pest in India. It is not of special conservation concern and is well represented in zoos and private collections throughout the world. DOI: 10.1644/813.1.

  • Damaliscus Pygargus Phillipsi – Blesbok
    Damaliscus pygargus phillipsi – Blesbok colour pattern (Fabricius et al. 1989). Hybridisation between these taxa threatens the genetic integrity of both subspecies (Skinner & Chimimba 2005). Assessment Rationale Listed as Least Concern, as Blesbok are abundant on both formally and privately protected land. We estimate a minimum mature population size of 54,426 individuals (using a 70% mature population structure) across 678 protected areas and wildlife ranches (counts between 2010 and 2016). There are at least an estimated 17,235 animals (counts between 2013 and 2016) on formally Emmanuel Do Linh San protected areas across the country, with the largest subpopulation occurring on Golden Gate Highlands National Park. The population has increased significantly Regional Red List status (2016) Least Concern over three generations (1990–2015) in formally protected National Red List status (2004) Least Concern areas across its range and is similarly suspected to have increased on private lands. Apart from hybridisation with Reasons for change No change Bontebok, there are currently no major threats to its long- Global Red List status (2008) Least Concern term survival. Approximately 69% of Blesbok can be considered genetically pure (A. van Wyk & D. Dalton TOPS listing (NEMBA) None unpubl. data), and stricter translocation policies should be CITES listing None established to prevent the mixing of subspecies. Overall, this subspecies could become a keystone in the Endemic Yes sustainable wildlife economy. The common name, Blesbok, originates from ‘Bles’, the Afrikaans word for a ‘blaze’, which Distribution symbolises the white facial marking running down Historically, the Blesbok ranged across the Highveld from the animal’s horns to its nose, broken only grasslands of the Free State and Gauteng provinces, by the brown band above the eyes (Skinner & extending into northwestern KwaZulu-Natal, and through Chimimba 2005).

  • The Eastern Cape –
    The Eastern Cape – Revisited By Jeff Belongia A return to South Africa’s Eastern Cape was inevitable – the idea already firmly planted in my mind since my first visit in 1985. Africa, in general, has a wonderful yet strange control over the soul, and many writers have tried to express the reasoning behind it. I note this captivation and recognize the allure, and am too weak to resist. For me, Africa is what dreams are made of – and I dream of it daily. Dr. Martin Luther King was wise when he chose the phrase, “I have a dream.” He could have said, “I have a strategic plan.” Not quite the same effect! People follow their dreams. As parents we should spend more time teaching our children to dream, and to dream big. There is no Standard Operating Procedure to get through the tough times in life. Strength and discipline are measured by the depth and breadth of our dreams and not by strategic planning! The Catholic nuns at Saint Peter’s grade school first noted my talents. And they all told me to stop daydreaming. But I’ve never been able to totally conquer that urge – I dream continually of the romance of Africa, including the Eastern Cape. The Eastern Cape is a special place with a wide variety of antelope – especially those ‘pygmy’ species found nowhere else on the continent: Cape grysbok, blue duiker, Vaal rhebok, steenbok, grey duiker, suni, and oribi. Still not impressed? Add Cape bushbuck, mountain reedbuck, blesbok, nyala, bontebok, three colour phases of the Cape springbok, and great hunting for small cats such as caracal and serval.

  • Connochaetes Gnou – Black Wildebeest
    Connochaetes gnou – Black Wildebeest Blue Wildebeest (C. taurinus) (Grobler et al. 2005 and ongoing work at the University of the Free State and the National Zoological Gardens), which is most likely due to the historic bottlenecks experienced by C. gnou in the late 1800s. The evolution of a distinct southern endemic Black Wildebeest in the Pleistocene was associated with, and possibly driven by, a shift towards a more specialised kind of territorial breeding behaviour, which can only function in open habitat. Thus, the evolution of the Black Wildebeest was directly associated with the emergence of Highveld-type open grasslands in the central interior of South Africa (Ackermann et al. 2010). Andre Botha Assessment Rationale Regional Red List status (2016) Least Concern*† This is an endemic species occurring in open grasslands in the central interior of the assessment region. There are National Red List status (2004) Least Concern at least an estimated 16,260 individuals (counts Reasons for change No change conducted between 2012 and 2015) on protected areas across the Free State, Gauteng, North West, Northern Global Red List status (2008) Least Concern Cape, Eastern Cape, Mpumalanga and KwaZulu-Natal TOPS listing (NEMBA) (2007) Protected (KZN) provinces (mostly within the natural distribution range). This yields a total mature population size of 9,765– CITES listing None 11,382 (using a 60–70% mature population structure). This Endemic Yes is an underestimate as there are many more subpopulations on wildlife ranches for which comprehensive data are *Watch-list Threat †Conservation Dependent unavailable.

  • The Ecology of Large Herbivores Native to the Coastal Lowlands of the Fynbos Biome in the Western Cape, South Africa
    The ecology of large herbivores native to the coastal lowlands of the Fynbos Biome in the Western Cape, South Africa by Frans Gustav Theodor Radloff Dissertation presented for the degree of Doctor of Science (Botany) at Stellenbosh University Promoter: Prof. L. Mucina Co-Promoter: Prof. W. J. Bond December 2008 DECLARATION By submitting this dissertation electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the owner of the copyright thereof (unless to the extent explicitly otherwise stated) and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Date: 24 November 2008 Copyright © 2008 Stellenbosch University All rights reserved ii ABSTRACT The south-western Cape is a unique region of southern Africa with regards to generally low soil nutrient status, winter rainfall and unusually species-rich temperate vegetation. This region supported a diverse large herbivore (> 20 kg) assemblage at the time of permanent European settlement (1652). The lowlands to the west and east of the Kogelberg supported populations of African elephant, black rhino, hippopotamus, eland, Cape mountain and plain zebra, ostrich, red hartebeest, and grey rhebuck. The eastern lowlands also supported three additional ruminant grazer species - the African buffalo, bontebok, and blue antelope. The fate of these herbivores changed rapidly after European settlement. Today the few remaining species are restricted to a few reserves scattered across the lowlands. This is, however, changing with a rapid growth in the wildlife industry that is accompanied by the reintroduction of wild animals into endangered and fragmented lowland areas.
