Municipality. A special word of gratitude is extended to every stakeholder within the Overberg District The development of this Wetland Report strengthens Municipality, who constructively engages and assists and supports the Environmental Management Policy, in improving and safeguarding our wetlands Spatial Development Framework and Integrated Development Plan and highlights the important role that wetlands play in Overberg District Municipality. It further confirms the important contribution of our natural resources in developing resilient communities. As the effects of climate change become more evident it is clear that the prevailing status will no longer be sufficient to maintain the ecological integrity of resources in Overberg District Municipality. Overberg District Municipality actively works towards the developing and strengthening of long term partnerships to ensure a collective response to MR V M GIBBS-HALLS address environmental pressures.

The potential presence of this species at the proposed development site requires careful consideration in terms of mitigation measures. The habitat survey took place in June 2014, which is outside of the species’ breeding season, but still provided an opportunity to assess wetland condition and vegetation to give an indication of suitability for Pickersgill’s Reed Frog. The habitat assessment indicates that the wetland areas on site are of a structure and vegetative composition that are suitable to Pickersgill’s Reed Frog and it is recommended that further surveys for the species are conducted during the peak breeding period to confirm species presence and guide recommendations regarding possible mitigation measures. Terms of Reference 1. Undertake a site visit to identify all potential Pickersgill’s Reed Frog habitats onsite based on the latest current understanding of their habitat requirements. 2. Identify the likelihood of occurrence for each of the habitats identified.

  • A Plant Ecological Study and Management Plan for Mogale's Gate Biodiversity Centre, Gauteng
    A PLANT ECOLOGICAL STUDY AND MANAGEMENT PLAN FOR MOGALE’S GATE BIODIVERSITY CENTRE, GAUTENG By Alistair Sean Tuckett submitted in accordance with the requirements for the degree of MASTER OF SCIENCE in the subject ENVIRONMENTAL MANAGEMENT at the UNIVERSITY OF SOUTH AFRICA SUPERVISOR: PROF. L.R. BROWN DECEMBER 2013 “Like winds and sunsets, wild things were taken for granted until progress began to do away with them. Now we face the question whether a still higher 'standard of living' is worth its cost in things natural, wild and free. For us of the minority, the opportunity to see geese is more important that television.” Aldo Leopold 2 Abstract The Mogale’s Gate Biodiversity Centre is a 3 060 ha reserve located within the Gauteng province. The area comprises grassland with woodland patches in valleys and lower-lying areas. To develop a scientifically based management plan a detailed vegetation study was undertaken to identify and describe the different ecosystems present. From a TWINSPAN classification twelve plant communities, which can be grouped into nine major communities, were identified. A classification and description of the plant communities, as well as, a management plan are presented. The area comprises 80% grassland and 20% woodland with 109 different plant families. The centre has a grazing capacity of 5.7 ha/LSU with a moderate to good veld condition. From the results of this study it is clear that the area makes a significant contribution towards carbon storage with a total of 0.520 tC/ha/yr stored in all the plant communities. KEYWORDS Mogale’s Gate Biodiversity Centre, Braun-Blanquet, TWINSPAN, JUICE, GRAZE, floristic composition, carbon storage 3 Declaration I, Alistair Sean Tuckett, declare that “A PLANT ECOLOGICAL STUDY AND MANAGEMENT PLAN FOR MOGALE’S GATE BIODIVERSITY CENTRE, GAUTENG” is my own work and that all sources that I have used or quoted have been indicated and acknowledged by means of complete references.

  • Havens of Biodiversity, and Places That Allow People to Connect with Natural Habitats and Ecosystems, Will Become Increasingly More Valuable for Future Generations
    Supplement to Veld & Flora, Vol. 93(4) December 2007 1 booklet3_FINAL_for print.indd 1 2007/11/02 10:50:33 AM FOREWORD The Botanical Society of South Africa (BotSoc) has been a partner and supporter of the South African National Biodiversity Institute (SANBI) and its forerunners for over 90 years. This supplement to Veld & Flora focuses on other “biodiversity” (birds, mammals, insects, etc.) rather than just our core interest, which is “plant diversity”. It is an example of BotSoc embracing the change which Dr Bruce McKenzie has come about since SANBI replaced its predecessor Executive Director, BotSoc the National Botanical Institute (NBI) and also supports one of the principles contained in BotSoc’s Centenary Charter (see Veld & Flora, March 2006) which outlines our commitment to supporting SANBI and its mandate. In this regard the BotSoc warmly welcomes the first CEO of SANBI, Dr Tanya Abrahamse, and looks forward to working with her and her team in tackling new challenges, some of which she has spelt out in her foreword to the supplement.
