Many conservation professionals are familiar with the Convention on International Trade in Endangered Species (CITES), Migratory (CMS), Biological Diversity (CBD), Ramsar Convention, and World Heritage Convention. Regional instruments, such as those focusing Africa, Antarctica, or Europe, also conspicuous features of arena. Other international wildlife agreements focus particular species, polar bears albatrosses, transboundary protected areas, huge Kavango-Zambezi Transfrontier Conservation...
The South African government has recently proposed a streamlined environmental impact assessment (EIA) process to fast-track decision-making and expedite broad range of activities linked the construction upgrading tourism infrastructure, maintenance, conservation rehabilitation in Kruger National Park (KNP). This proposal is founded on adoption KNP’s Management Plan Generic Environmental Programme as management instruments (EMIs) under Act 107 1998. intention exclude Parks (SANParks),...
What do geese (Anser spp., Branta spp.) and wolves (Canis lupus) in Europe have common with elephants (Loxodonta africana) southern Africa? In fact, quite a lot. All three enjoy protected sta...
Flowers of the red-fleshed female kiwifruit selection 'Hort22D' (diploid Actinidia chinensis) were hand pollinated with pollen from each three males: 'Bruce' A. chinensis), M248 (tetraploid and 'Chieftain' (hexaploid deliciosa). The resulting fruit evaluated at four dates through growing season after storage. By final harvest, pollination by had a 47% higher total anthocyanin concentration weighed 38% more than 'Chieftain', but there was no association between weight. Total individual seed...
Abstract In South Africa, fish kill events are increasing in frequency because of multiple stressors associated with managing natural resources. Despite the ecosystem services fish, Africa's progressive legislation towards environmental protection seems to negate management kills. this study, we provide an overview reports and regulations acute pollution spills resulting Africa. addition, highlight implication these using a event from 2019 on Msunduzi River, as case study. The River showed...
Background: Although formal protected areas in South Africa date back to the turn of 19th century, requirements for area management plans only became mandatory a century later. Prior promulgation World Heritage Convention Act 49 1999, and subsequently National Environmental Management: Protected Areas 57 2003, were voluntary, guidance plan’s content was fragmented across an array international, national provincial policy instruments.Objectives: As there has been little academic debate on...
Abstract Differences in pasture species composition as a consequence of grazing were used to develop proposed classification response grazing, for both the Combretum apiculatum and Acacia tortilis communities northern Transvaal mixed bushveld. The limited value this approach is discussed view likely interactions with other driving forces. Woody vegetation changed veld but not apicalatum veld. Two thresholds change indicated, one which coincided soil change. recognizing rather than attempting...
In 2008, South Africa adopted its ‘National Norms and Standards for the Management of Elephants in Africa’. Concern has subsequently been raised as to whether these norms standards apply free-ranging elephant on land, which had not enclosed with a fence express purpose containing animals other game property. The application pivots owner(s) property have taken possession accordance common law applicable game, or given effect provisions Game Theft Act. To address this concern, article briefly...
Elephant culling is included in National Norms and Standards for the Management of Elephants Republic South Africa, as a last-resort option to reduce elephant population size when required meet reserve objectives. Recent judgments African courts have emphasised importance considering animal welfare conservation. We assess approved method family units, terms legal policy framework well wellbeing. find that current likely be inhumane, potentially inconsistent with Constitution, interpreted by...
The proposal to eradicate tsetse flies from South Africa, including its protected areas, via the sequential aerosol technique combined with sterile insect reduce trypanosomiasis in cattle did not present an appropriate analysis of impacts that implementation would have on biodiversity. Not only be contrary African laws protecting and conserving biodiversity, but it also negative consequences for conservation Some are reviewed, extirpations ecological ecosystem processes services. Alternative...
The influence of leaf age on infection Actinidia species by Pseudomonas syringae pv actinidiae (Psa) was investigated using two approaches (a) inoculation potted Hayward and Hort16A kiwifruit plants (b) whole leaves in a detached assay Whole were spray inoculated with Psa biovar 3 (haplotype NZV; PsaV) maintained saturated environment Flecking evident some the 8 days after Many flecks later became necrotic spots halos similar to infections that have been observed field With both methods...
A significant proportion of South African biodiversity occurs in extensive private wildlife areas. As such, the continuance these reserves is paramount to conservation country’s biodiversity. The areas are, however, vulnerable being divided into smaller camps as landowners enter new and rapidly growing industry selective breeding intensive management antelope predators. Concerns are raised long-term consequences products impacts this on, inter alia, integrity wildlife, landscapes facilities...
The public trust doctrine was deliberately included in South African environmental legislation; the best interests of citizens and future generations, it empowers to ensure that government safeguards country's natural cultural environment. This article examines Africa's law order derive an understanding origins potential application doctrine. While prima facie origin is Bill Rights right 1996 Constitution, multilateral agreements Africa appear have had a significant influence on how...
The world's largest predators, like their prey species and biodiversity at large, face increasing impacts from climate change, in addition to various other threats. Such include the shrinking disruption of habitat (e.g., polar bear, wolverine); range shifts, especially upslope snow leopard, Ethiopian wolf) poleward golden jackal); reduced availability key resources as water becomes scarcer populations suffer extreme weather, disease or climate-related Gobi cheetah); increased human–wildlife...
The explicit incorporation of the public trust doctrine into South Africa’s Bill Rights in SouthAfrica’s Constitution, and its subsequent codification country’s environmentalbiodiversity, protected area, water, minerals heritage legislation, occurred to a large extentwithout applause or fanfare. It is apparent that 20-odd years since adoption existence importance within theacademic legal fraternities, bureaucratic decision-making courts have largely beenoverlooked. This observation evokes...
The choice of pollen donor may sometimes affect fruit characteristics kiwifruit. In this study, flowers a red-fleshed kiwifruit selection were hand-pollinated with from males diploid and tetraploid Actinidia chinensis var. hexaploid A. deliciosa. resulting evaluated for key commercial traits after storage. All had intense red colour in the centre, but those pollination by or significantly more coloration than male. Malic acid, total sucrose soluble solids concentrations, titratable acidity...
Abstract Grazing‐induced gradients in pasture species composition were characterized for the red turfveld of Northern Transvaal savanna. A proposed classification response to grazing was developed and influence state variables driving forces other than recognized. It is argued that present status woody vegetation reflects a variety influences on scales. Its effect forage production needs quantification. Relationships between index density “tree equivalents” demonstrated. Differences fire...
Wildlife and particularly economically valuable game are likely to be displaced as a result of the habitat change. This displacement is expressed, inter alia , in emigration more suitable habitat. The impacts climate change, therefore, may have significant consequences on economic well-being wildlife areas, which derived from, amongst others, sale excess animals, hunting tourism. article investigates whether South African statute common law provide sufficient protection landowners, from...
