REFERENCES 84 4 Executive Summary Mr. Tony Hayman (Marloth Park Property Owners Association: MPPOA) requested Rhengu Environmental Services (RES) to conduct an updated ecological study of the Marloth Park Wildlife Estate (MPWE). The survey was commissioned to determine the prevailing veld condition of the property and to identify the ecological problems facing the management of this very special system. The approach to this survey and to this document is based on the Ecological Report submitted by Ben Orban in 2006. The Orban Report, although comprehensive, proved to be very cumbersome to read and understand and few if any of the recommendations were implemented by the Marloth Park Management Team (MPMT). What was now required was to update the Orban Report and encapsulate the important aspects of its’ contents into a functional, practical, hands on version of events describing the prevailing wildlife conditions. This report should then provide for a more dynamic, down to earth instruction manual on wildlife management issues, problems and solutions. The results of the study were used to compile an Environmental Management Report (EMR). The following key aspects are considered important and or will require attention by Management: Game species do not utilise the entire 528 ha of the parkland available in the Reserve and this fact has implications for the stocking rate of the property. Although not all the development stands will be developed (some land owners have purchased more than 1 stand), the 528ha will be available to wildlife in the long term whilst undeveloped stands will add some additional grazing space on an ad hoc basis. The expected stocking rate has dropped significantly to the extent that the majority of the animals must be removed to avoid die offs and starvation. Remove 165 LAU’s of impala, warthog, giraffe and kudu as described in the report. Monitor the condition of browsers over the next twelve months to collect reliable information on the well being of these species. This must include the qualification of animal condition as a percentage of the population numbers. Stocking Rate: The ongoing monitoring of veld condition; animal condition; fire management and associated factors, as listed in paragraph 7, will in future assist with decision making in this regard. In the long term it is estimated that with improved veld conditions and grass species composition, the stocking rate can be adjusted and re-defined. None of the 15 sites surveyed at this stage of the season satisfy the criteria for a management burn (more than 3000kg/ha and more than 60% decreaser/increaser 1 species in the field layer). Decreaser grasses (climax, palatable, good grasses) comprise 12 % of the MPWE field layer. This figure must be improved over time. Grazing impact must be reduced/minimised on all the feeding sites. Supplementation must take place on under-utilised sites and rotated regularly (every 6 weeks). More than 62% of the field layer consists of weeds which are indicative of overgrazed pasture conditions. Alien- and invasive plants (including weeds) are contributing to lowering the carrying capacity of the veld. These plants must be removed systematically. Implement the veld rehabilitation programme as described in chapter 7. Remove 66% of the sickle bush trees. A designated Game Farm Manager must supervise and oversee the scientific management of the property on an ongoing basis. This will include the implementation of the monitoring programme and the works schedule. MPWE residents/shareholders and owners must trust the decisions taken by the designated manager, is so far as these have bearing on the wildlife management component of the Estate. When in doubt applicable expertise and advice can be sourced to confirm or verify certain aspects. The EMR was translated into a set of recommendations which if implemented over time, should ensure a sustainable product which will function within the framework of Integrated Environmental Management. 5 1.

Inspection/s Reason for Site All game reserves and game areas in South Africa are obliged to Visit and Field abide by various acts and statutes of legislation. To this end the Work. National Environmental Management Act and specifically the Biodiversity Protection Act are of particular importance. To ensure that the Marloth Park Wildlife Estate abides by all aspects pertaining to environmental law and to manage the Estate in a responsible, sustainable way, the MPPOA: Environmental Management Committee took the decision to undertake an updated Ecological Study of the area. RES were appointed to undertake the surveys and determine the veld condition/carrying capacity of the reserve with special reference to identify and quantify the ecological potential of the area with the view to continuing the wildlife enterprise in a sustainable manner. The contents of this EMR, describes the status of the prevailing veld condition and the condition of the habitat available to game animals on the reserve. Finally, the EMR through a set of recommendations guides the MPPOA to implement a number of programmes which will benefit the habitat at Marloth Park and the well-fare of the wildlife in the medium to long term. A Browse Line is evident on key species of woody vegetation, e.g. Acacia spp. 8 3. LOCALITY INFORMATION Name of Place and Locality Marloth Park is found to the east of Hectorspruit, a few kilometres north of the N4 Maputo Corridor Toll Road in the Nkomazi District, Mpumalanga. Region Nkomazi District. Size of Development Approximately 1627ha. Approximately 528ha is available to conservation (Orban 2006). Certain stands have not been developed and may also be available to wildlife. 528ha is however guaranteed for use by wildlife in the long term. Magisterial District Nkomazi. Nearest Town/City Hectorspruit-Komatipoort. Nearest Main Road N4 Toll Road. Type of area where the development is located (mark all applicable blocks).

Settlement Industrial Homesteads Township Other: Tourism X Road X Building A plethora of man-made waterholes provide water for the wildlife at Marloth Park 9 4. PROJECT DESCRIPTION Current Status and Infrastructure: Access to the Estate and the game reserve is via the national road (N4) northwards to the Crocodile River. The MPWE has optimised many aspects of lifestyle living and provides for a variety in recreational opportunities, i.e. cycling; game viewing; birding; nature trails and hiking. This survey and report describes the issues pertaining to the wildlife/game “farming” operation. The reserve is fenced off with a security- and game fence which is electrified and patrolled daily. A 24 hour security service-access control and surveillance provides for all aspects of safety and security. Water supply for game is more than adequate with a number of earthen dams/impoundments, man-made troughs/water holes and drainage lines providing water to various habitat sections on the reserve. MPWE is home to a variety of land uses which include retirement homes, private lodges, commercial tourism lodges and supportive infrastructure including shops, restaurants and businesses that provide services to the above listed facilities. MPWE falls under the jurisdiction of the local Nkomazi Municipality, the latter providing municipal services including sewerage, electricity and water.
