1) BACKGROUND 1.1 Purpose of the plan Management plans for biodiversity stewardship sites are strategic documents that provide the framework for the development and operation of biodiversity stewardship sites. Biodiversity stewardship offers varying levels of formal protection of land with nature reserves being the highest level of protection and a recognised protected area in terms of the National Environmental: Management Protected Areas Act, No. 57 of 2003. Because of the importance of its biodiversity and ecological functions, Ingwehumbe Nature Reserve qualified to be declared as a nature reserve in terms of the Act. This management plan informs management at all levels, from the management authority through to support staff within partner organisations. The purpose of the management plan is to: • Provide the primary strategic tool for management of Ingwehumbe Nature Reserve, informing the need for specific programmes and operational procedures. • Provide for capacity building, future thinking and continuity of management. • Enable the landowner to develop and manage Ingwehumbe Nature Reserve in such a way that its values and the purpose for which it has been established are protected. • Ensure the effective management of Ingwehumbe Nature Reserve in accordance with relevant provincial, national and international norms and standards. • The plan outlines the implementation of the conditions laid out in the Protected Area Management Agreement for Ingwehumbe Nature Reserve, which are to: o Preserve the ecological integrity (including vulnerable and ecologically sensitive areas) of the nature reserve. o Conserve the biodiversity of the nature reserve. o Protect areas representative of all ecosystems, habitats and species naturally occurring there. o Protect threatened or rare species. o Assist in ensuring the sustained supply of environmental goods and services provided by the nature reserve. o Provide for the sustainable use of natural and biological resources. o Create or augment destinations for nature-based tourism. o Manage the interrelationship between the natural environment, human settlement and economic development.

1.3 Alignment with MET T Management effectiveness is defined by the IUCN’s World Commission on Protected Areas (WCPAs) as the assessment of how well a protected area is being managed – primarily the extent to which it is protecting values and achieving goals and objectives (Hockings, Stolton & Dudley 2000; Hockings et al. 2006). The assessment of management effectiveness using the Management Effectiveness Tracking Tool (METT-SA Version 3, 2015) is not a management performance assessment but is intended to identify areas in which management effectiveness can be improved within a protected area and within the organisation managing the protected area. As far as possible, this management plan has been aligned with the METT, which focuses on six elements of protected area management: 1. Understanding the context of existing values and threats. 2. Protected area planning and design. 3. The allocation of resources to the protected area. 4. The processes that are implemented in managing a protected area. 5. The outputs of management actions. 6. The outcomes or impacts of management actions. It must be understood that not all aspects of the METT will be relevant to Ingwehumbe Nature Reserve but that the METT is able to identify areas in which to focus management activities in an effort to address deficiencies and improve management. It thus provides a baseline upon which future management effectiveness can be measured and improved. 1.3 Introduction The Ingwehumbe Nature Reserve (1031.059ha) is located in the south-east corner of the Pietermaritzburg and midlands region of the KwaZulu-Natal Midlands, approximately 15km south east of the village of Eston in KwaZulu- Natal, in a predominantly sugar cane growing area (Fig.2). The nature reserve is characterised by a variety of different vegetation types including the Critically Endangered KwaZulu-Natal Sandstone Sourveld, Moist Coast Hinterland Grassland, Eastern Valley Bushveld, KZN Hinterland Thornveld and Eastern Scarp Forest that support large numbers of threatened and endemic species. The Ingwehumbe Nature Reserve provides an important example of these habitat types within the region. It falls within the Mkhambathini Local Municipality and the uMgungundlovu District Municipality. This region also forms part of one of the oldest conservancies, namely the Beaumont Eston Conservancy. This site will play a very important role in the conservation of vegetation types, especially the Critically Endangered KZN Sandstone Sourveld, as well as a large number of threatened and endemic plant and animal species.

Figure 2. Regional location of Ingwehumbe Nature Reserve. 1.4 The values of Ingwehumbe Nature Reser ve The values of a place are those remarkable attributes that exemplify it, which led to it being identified as a priority for the Biodiversity Stewardship Programme and to be proclaimed as a nature reserve. The values are important in planning and management, as they are the aspects of the place that must be protected. The values of Ingwehumbe Nature Reserve include: Natural values • Ingwehumbe Nature Reserve contains a large variety of vegetation types, including the Critically Endangered KZN Sandstone Sourveld, Moist Coast Hinterland Grassland, Eastern Valley Bushveld, KZN Hinterland Thornveld and Eastern Scarp Forest. Of note is the abrupt contrast from sandstone grassland to Valley Bushveld habitat. • Sense of space, beauty, views and vistas of the area. Species values • Ingwehumbe Nature Reserve provides suitable I N G W E H U M B E N AT U R E R E S E R V E MANAGEMENT PLAN 5
habitat for high numbers of endemic and threatened plant and animal species. Ecosystem service • The Mgwahumbe River and its tributaries that values flow through the property are an important part of Umkomaas catchment • The nature reserve is a large tract of functional natural habitat in a largely transformed region/landscape Ecosystem function • Ingwehumbe Nature Reserve has a significant values altitudinal gradient that facilitates climate change adaptation. • Ingwehumbe Nature Reserve has high habitat heterogeneity including grassland, bushveld, scarp forest, rivers, wetlands, waterfalls and cliffs. Socio economic • The large variety of recreational activities include: values mountain biking fly fishing (indigenous yellow fish), abseiling, hiking, bird watching, game viewing, 4x4 track, botanical walks, river lodge. Cultural and historic • A long history of people with strong ties to the values land. Consistent with Section 17 of the Protected Areas Act, the purpose of Ingwehumbe Nature Reserve is to: • Protect an ecologically viable, representative area of KZN Sandstone Sourveld, Eastern Scarp Forest, Moist Coast Hinterland Grassland, KZN Hinterland Thorn veld and Eastern Valley Bushveld and its associated biodiversity in efforts to achieve provincial and national protected area targets. • Protect the ecological integrity and functioning of ecosystems and water resources of the region. • Protect the biodiversity of the area, in particular threatened, rare and endemic species. • Contribute towards the ecological functioning of the Mgwahumbe River catchment and its associated water resources through the sustained supply of environmental goods and services. • Provide a destination for nature-based tourism that contributes to economic development in the region. • Ensure the sustainable use of natural resources including by hunting. 1.4.1 Protection of the values The protected area’s values, in particular those that underlie the functioning of its ecosystems and the protection of its rare and threatened species, will be given the highest degree of protection to ensure the persistence of these systems predominantly unaltered by human activity. I N G W E H U M B E N AT U R E R E S E R V E MANAGEMENT PLAN 6
1.4.2 Ecosystem-based management Decision-making associated with the protection of the reserve’s ecosystems will be scientifically based on internationally accepted principles and concepts of conservation biology. The protected area ecosystems will be managed with minimal interference to natural processes. Specific management may be desirable, when the structure or function of a habitat or ecosystem has been significantly altered by human induced impacts or previous management. Specific management will only be considered when this option is the best alternative available to restore ecological integrity. Where directed management is required, it will be based on scientific research, and will employ techniques that emulate natural processes as closely as possible. 1.5 Adaptive management The preparation of this management plan has been undertaken based on the guiding principles of adaptive management, which is a structured, iterative process in which decisions are made using the best available information, with the aim of obtaining better information through monitoring of performance (Fig.3). In this way, decision making is aimed at achieving the best outcome based on current understanding, whilst accruing the information needed to improve future management. Adaptive management can lead to revision of a part or if necessary the whole management plan. I N G W E H U M B E N AT U R E R E S E R V E MANAGEMENT PLAN 7
Figure 3. The adaptive management cycle (Management Strategy Evaluation, 2009). Adaptive management enables landowners and managers to: i) Learn through experience. ii) Take account of, and respond to, changing factors that affect the biodiversity stewardship site. iii) Develop or refine management processes. iv) Adopt best practices and new innovations in biodiversity conservation management. v) Demonstrate that management is appropriate and effective.

2) DESCRIPTION OF INGWEHUMBE NATURE RESERVE AND ITS CONTEXT 2.1 The legislative basis for the management of Ingwehumbe Nature Reser ve There is a large body of legislation that is relevant to the management of Ingwehumbe Nature Reserve, but the primary legislation guiding the management of protected areas is the National Environmental Management: Protected Areas Act (No.57 of 2003). The Protected Areas Act establishes the legal basis for the creation and administration of protected areas in South Africa, as its objectives include provisions “for the protection and conservation of ecologically viable areas representative of South Africa’s biological diversity and its natural landscapes”. The Act sets out the mechanisms for the declaration of protected areas and the requirements for their management. A detailed list of relevant legislation is provided in Appendix B. Landowners should familiarise themselves with the purpose and contents of the statutes and their subsequent amendments and regulations. 2.1.1 Proclamation status of Ingwehumbe Nature Reserve Nature Reserve status was recommended for the Ingwehumbe site by the KZN Biodiversity Stewardship Review Panel on 4 Feb 2013 and approved by the KZN Biodiversity Stewardship Working Group on 7 Feb 2013, following a site assessment on 28 November 2012. The landowners of the properties comprising Ingwehumbe Nature Reserve have committed to proclaiming the site as a nature reserve in terms of Section 23 of the National Environmental Management: Protected Areas Act (No.57 of 2003). A copy of the gazette notice, proclaiming Ingwehumbe as a nature reserve will be provided in Appendix C. Ingwehumbe Nature Reserve has been surveyed over the properties or parts thereof listed below (Fig.4). Table 1. Land ownership of Ingwehumbe Nature Reserve.

Figure 4. Ingwehumbe Nature Reserve and its constituent properties. 2.1.2 Invasive species control in terms of the Biodiversity Act In terms of Section 76 of the National Environmental Management: Biodiversity Act (No.10 of 2004), the management authority of a protected area must incorporate an invasive species control plan in the protected area management plan. This is addressed in Sections 3 and 4 below. 2.2 The regional and local planning context of Ingwehumbe Nature Reser ve 2.2.1 Regional and local planning framework Ingwehumbe Nature Reserve falls within uMgungundlovu District Municipality and the Mkhambathini Local Municipality, which set the regional and local planning frameworks. The status of the reserve is reflected in the land use planning schemes. Almost the entire area of Ingwehumbe Nature Reserve is classified as CBA Irreplaceable Terrestrial and CBA Optimal Terrestrial according to uMgungundlovu District Municipality’s Critical Biodiversity Areas Map (Fig.5). I N G W E H U M B E N AT U R E R E S E R V E MANAGEMENT PLAN 10
Figure 5. Ingwehumbe Nature Reserve in the context of uMgungundlovu DM Critical Biodiversity Areas Map. According to the Environmental Management Framework for the uMgungundlovu District Municipality (INR 2017) as a declared Nature Reserve (Protected Area) the sensitivity level is very high and activities that would result in transformation or net loss of critical biodiversity elements should not be undertaken in this zone. Activities that are compatible with biodiversity management objectives and that would result in a nett increase in biodiversity should be supported. (p36) Maintain, enhance, and where possible, protect areas of high biodiversity value through sustainable development planning and land use management practices that promote biodiversity patterns and processes across a more connected and biodiverse landscape. (p38) The uMgungundlovu District Municipal IDP recognises good tourism potential as a major strength identifies the farming area between Camperdown and Ezimwini (including the existing protected areas within Mkhambathini Municipality - Mpushini Protected Reserve, Camperdown Nature Reserve, Killarney Isle and Gwahumbe Game Reserve and Mid Illovo, Eston, Manderston and Tala Game Reserve Area) as an agri eco-tourism and food production area. The Mkhambathini IDP (2016-2021 p99) states that he remaining undisturbed land should be protected wherever possible since it provides habitats for various species. The maintaining of indigenous habitats will assist towards augmenting biodiversity in the area. I N G W E H U M B E N AT U R E R E S E R V E MANAGEMENT PLAN 11
2.2.2 Protected areas expansion A long term goal is to expand the reserve as the opportunities arise by identifying areas adjacent to Ingwehumbe Nature Reserve for possible expansion of the conservation area. The following properties have expressed interest in becoming recognised conservation areas Skiddaw, Scawfell, Gwahumbe Farm, Gwahumbe Game and Spa, Hope Valley, Giggleswick and Buckawbrau. These properties need to be engaged by the KZN Biodiversity Stewardship Programme. 2.3 The history of Ingwehumbe Nature Reser ve Origin of the name “Ingwehumbe” (Neil Hampson pers. comm. 2017) “The name of the valley came to my attention about in 1990 as for years I had been trying to find out the meaning of the word Gwahumbe as it was spelt on the road signs and in all references. An old African man came to the farm one morning and asked permission to bless the spirits of his family at a site near to what we call the Waterfall. He told me that he had grown up in the valley and as a small boy herded the cattle along the river. He said his grandparents always warned them not to herd the cattle near the “Ingwe Hhumbe”. Ingwe meaning leopard and humbe meaning caves - “Leopard Caves”. So at last after many years the true name became known to me. It really made sense and ironically leopard are seen on regular occasions in the valley. In fact spoor of a leopard and cub were recorded by my ranger on the 18/3/2016”. History of the Ingwehumbe Nature Reserve and surrounds Historically, this region once formed part of the ancient elephant trail as they moved between their winter-feeding grounds in the mangrove swamps of what is now Durban, to their summer habitat, the nearby Byrne Valley. This trail was later utilised by Boer Pioneers as a wagon route from the Cape to Durban. The area was settled by the Stainbank and Gurney families in the 1870s. Agriculture at the turn of the last century consisted of tobacco growing for which a factory was built in the Gwahumbe Valley. The following notes on the history of the area were provided by Neil Hampson, a local resident whose family has lived in the area for many years. “Herewith a short resume of what I know and what I was told by my father Garnet Hampson who was one of the first managers to be employed by Willy Pearce the owner of the then Illovo Sugar Mill. • All cane was hauled by oxen on coco pan trucks on rails laid out for harvesting and then transferred to a narrow gauge trucks to be hauled down to the mill at Illovo. Some 500 head of oxen were grazed down the I N G W E H U M B E N AT U R E R E S E R V E MANAGEMENT PLAN 12
Gwahumbe Valley and also Hall’s Farm which is now Tala Reserve. My folks were engaged in 1938 and I have a picture of them sitting in a mule drawn trap close to where the old tobacco factory was. The tobacco was of a very high standard and won many top awards at the Royal Show in Pietermaritzburg. • I personally broke down the last Illovo dip tank in the valley in 1980 which was made of imported pig iron, a very strong type of cast iron. • Col. Montgomery was bequeathed the land, Ismont Farm by Queen Victoria for his services rendered to her Majesty in the British Fusiliers. He built his double story home to resemble a fort, complete with gun turrets and meter thick stone walls. The house has been occupied until 3 years ago when a freak hurricane destroyed it. Istere Montgomery and 2 daughters less than 3 years old lie buried at the top of Mount Langford on the farm Ismont. The dates on the graves are 1860. • The valley, prior to the arrival of Lantana was open Savannah, grasslands. • I am open to correction but my certificate of Natural Heritage Site No 1 is I think one of four or five registered in the Valley and signed by Mandela. • I have known the valley since a young boy of about 12 and spent many holidays with pellet guns, bare foot, swimming and exploring and doing what all boys dreamt of in those days. It has been an honour and privilege to have been able to conserve the part I have and my dream is that one day the entire 16 kilometers will become a Natural Heritage site in its entirety.” Botanical collecting history of the area It is related that the Durban Herbarium was stocked in the late 1800’s from the valley. It was a hard day’s ride from Durban and many, many specimens of plants were sourced from this precious valley and I understand went on to the London Herbarium (most likely Kew). (Related to Neil Hampson by Neville Power of Arden Farm, Mid-Illovo, whose family name goes back to Powerscourt i.e. above the valley). Later, in the 1950’s, the area was again an important collecting site for botanists who contributed to the impressive plant species list (Appendix D). 1 Attempts to trace this number have so far been unsuccessful I N G W E H U M B E N AT U R E R E S E R V E MANAGEMENT PLAN 13
2.4 Ecological context of Ingwehumbe Nature Reser ve 2.4.1 Climate and weather The Ingwehumbe area has relatively mild seasonal climatic patterns. Mean annual rainfall ranges from 738mm in the valley to 956mm at the higher altitudes, and occurs mostly during the spring and summer seasons, but with some rain in winter. Mist is common and adds additional moisture. Winters are generally very stable climatically and characterised by cold dry conditions. Some frost does occur. Figure 6. Mean monthly rainfall and temperature data for the major Bioreseource units of Ingwehumbe. 2.4.2 Topography Ingwehumbe Nature Reserve altitudes range from higher lying areas of up to 845m above mean sea level, dropping rapidly down cliffs and steep slopes to the valley bottom along the course of the Mgwahumbe River to 291m asl., a total of 554m Fig.7). The topography of the area has an impact on management activities carried out on the reserve. Access to the valley bottom is difficult with the access road being steep and eroded in some areas. Only high clearance vehicles are used, with 4X4 vehicles required in some places. Due to the steep nature of the terrain appropriate drainage of roads and carefully planned burning regimes are important to prevent erosion. I N G W E H U M B E N AT U R E R E S E R V E MANAGEMENT PLAN 14
Figure 7. Map showing topography of Ingwehumbe Nature Reserve and its surrounds. 2.4.3 Geology and soils The higher altitude plateau areas have shallow, nutrient-poor sandy soils derived from Ordovician Natal Group sandstones, with the dominant soil types being Inanda, Kranskop, Nomanci, Griffin and Hutton, which have a low susceptibility to erosion. The slopes and valley bottom are underlain by the sediments of the Karoo Supergroup with the mudstones, and the dominant soil types are Glenrosa and Mispah (Fig.8). These areas are highly susceptible to erosion I N G W E H U M B E N AT U R E R E S E R V E MANAGEMENT PLAN 15
Figure 8. Map showing the geology of Ingwehumbe Nature Reserve. 2.4.4 Hydrology The large Mgwahumbe River, a major tributary of the Lovu River flows along the valley bottom of the reserve. Two perennial streams feed this river from the north. The water quality of the river is dependent on agricultural practices upstream, but is currently in good condition. The Gwahambe Clear Water project is working from river source. There are no major NFEPA wetlands within the nature reserve, but numerous smaller wetlands are present.

2.4.5 Vegetation Five vegetation types are represented in the Ingwehumbe Nature Reserve (Table 2 & Fig.9) Table 2.

KwaZulu-Natal Sandstone Sourveld (Critically Endangered) occurs in KwaZulu-Natal on elevated sandstone plateaus from Mapumulo near Kranskop in the north to St Faiths near Port Shepstone in the south, between 500-1100m. It is a short, species rich grassland with scattered low shrubs and geoxylic suffrutices on flat or rolling plateau tops and steep slopes. This vegetation type is classified as critically endangered by EzemveloKZNWildlife and the South African National Biodiversity Institute (Mucina and Rutherford 2006, Jewitt 2011). It is noteworthy that the contribution of Ingwehumbe more than doubles the current protected extent. Eastern Scarp Forest occurs from near the Kei Mouth to southern Mpumalanga and from a biodiversity perspective is probably the most important forest type in South Africa (Boon, 2010). Biogeographically and in terms of biodiversity this is probably the most valuable forest type in South Africa with many endemic taxa. Eastern Valley Bushveld is found in the deeply incised valleys of rivers between 100 and 1000m asl. In the Eastern Cape and KZN. Semi deciduous savanna woodlands in a mosaic with thickets, often succulent and dominated by species of Euphorbia and Aloe KZN Hinterland Thornveld is found scattered immediately above eastern valley bushveld between 450 and 900m asl in river valleys. Open thornveld dominated by Acacia species on undulating plains on the upper reaches of river valleys. 2.4.7 Fire regime Current fire management is concentrated on maintaining the grasslands, where biennial block burning is more feasible than fire breaks. Perimeter breaks are burnt on perimeter of grasslands. The occurrence of wildfires is not as bad as in the past. The river, streams and forests act as natural barriers. Fire management agreements need to be put in place with neighbours to ensure that burning is cost effective and in line with management objectives e.g. burning of reserve boundary. Uncontrolled fires in the Bushveld on steep slopes could result in erosion. 2.4.8 Invasive species There are currently very high levels of Lantana camara, and to a lesser extent Chromolaena odorata and Solanum mauritianum, on the steep slopes of the river valley. Small patches of Canna indica and an exotic Plectranthus sp. are present in the grasslands above the valley. Some Sesbania punicea is also present.

Table 3. List of alien invasive plants species found on Ingwehumbe Nature Reserve. Common name Scientific name CARA category Lantana Lantana camara 1 Triffid weed Chromolaena odorata 1 Bugweed Solanum mauritianum 1 Indian shot Canna indica 1 Wattle Acacia mearnsii 1 Red Sesbania Sesbania punicea 1b In terms of the NEM: Biodiversity Act (No.10 of 2004) and the Conservation of Agricultural Resources Act (CARA – No.43 of 1983), landowners are required to control and eradicate listed invasive alien species on their land. CARA categorises such plants on the following basis: Category 1: Plants that may not be grown and must be eradicated. Category 2: Plant species with commercial value, which may only be grown with a permit under controlled circumstances. Category 3: Plants which have amenity value and which may be grown, but not planted, propagated or imported. While weed control is active in the proposed nature reserve area using chemicals, inaccessibility of the very steep river banks is a huge challenge. Biocontrol agents need to be investigated as a method of control for these species. Lantana biocontrol has been tried but the agent is adversely affected by cold temperatures. 2.4.9 Plant species The Ingwehumbe Nature Reserve area has been well collected by many KZN botanists over a long period and more than 600 species have been recorded (Appendix D2). These include five Endangered species, 11 Vulnerable species, 6 Near Threatened species, 11 Declining species and two Rare species. There are 16 KZN endemics and 82 SA endemics. There is also an unconfirmed report of the Critically Endangered Brachystelma natalense. 2.4.10 Mammalian fauna A variety of antelope including Oribi (Endangered), Bushbuck, Grey Duiker, Blue Duiker (Vulnerable) , Kudu, Eland and Common Reedbuck occur on Ingwehumbe. Leopard tracks, serval, caracal, cape clawless otter, aardwolf, black-backed jackal, genet, aardvark, water & white tailed mongoose, striped weasel, honey badger, grey and slender mongoose, cane rats, bushpig and warthog have also been recorded (Appendix D3).

2.4.11 Avifauna Over 180 bird species have been recorded in this area. These range from forest species such as the trumpeter hornbill and narina trogon, waterfowl, a variety of raptors of which the Crowned Eagle is recorded to have bred in the valley for over twenty five years and Southern ground hornbill. Of particular note is Southern Ground Hornbill (Endangered) which bred on a ledge above the Ingwehumbe NR gorge until recently when the nesting site collapsed.A bird list from the neighbouring similar habitat Gwahumbe Game Reserve is included in Appendix D to note the species likely to be found on Ingwehumbe. 2.4.12 Herpetofauna (reptiles and amphibians) The following reptiles and amphibians are found on Ingwehumbe Nature Reserve: African Rock Python, Berg adder, Black mamba, Green mamba, Boomslang, Southern Brown Egg Eater Snake, Bush Squeaker, Flap Neck Chameleon, Bushveld Rain Frog, Common River Frog (Appendix D3). 2.4.13 Invertebrates A list of Invertebrates from EKZNW is included in Appendix D3. A number of the millipedes and molluscs are threatened and / or KZN endemics. 2.6 Socio-economic context I N G W E H U M B E N AT U R E R E S E R V E MANAGEMENT PLAN 20
Ingwehumbe Nature Reserve falls within the uMgungundlovu District Municipality and the Mkhambathini Local Municipality (Fig.10) which set the regional and local planning frameworks. Figure 10. Local municipality within which Ingwehumbe Nature Reserve falls The uMgungundlovu District Municipality 2015/16 Integrated Development Plan (IDP) highlights the good tourism potential and abundant water resources of the area. This emphasizes the importance of natural sites such as Ingwehumbe Nature Reserve, which can ameliorate degradation upstream and continue to provide important ecosystem goods and services downstream. The uMgungundlovu District Municipality EMP (2017) highlights tourism attraction as a strength and the importance of biodiversity conservation and the revenue generated by tourism associated with conservation as a key opportunity. Threats to the Mkhambathini Local Municipality outlined in a SWOT (strengths, weaknesses, opportunities and threats) analysis include growing pressure to protect sensitive vegetation such as Ngongoni and Valley Bushveld and that there is an increasing burden to protect the rivers and wetlands with limited resources available at the municipality.

3) STRATEGIC MANAGEMENT FRAMEWORK The following strategic framework is aimed at providing the basis for the protection, development and operation of the biodiversity stewardship site over the next five years and has been prepared collaboratively through a process involving the landowner, the biodiversity stewardship facilitator and Ezemvelo KZN Wildlife. The vision describes the overall long-term goal for the operation, protection and development of Ingwehumbe Nature Reserve. The objectives and strategic outcomes that follow are intended to provide the basis for the achievement of the vision. The objectives provide a broad description of the goals for each key performance area. The strategic outcomes, which flow from the objectives, set out what is needed to achieve the objectives, based on the management challenges, issues and opportunities described in Section 2 above. 3.1 Ingwehumbe Nature Reserve vision The ecological value of the Ingwehumbe Nature Reserve extends beyond its immediate surrounds, where it fulfils an important role in regional conservation and the provision of ecosystem services. The natural beauty, ecological value, habitat and species diversity and the presence of high numbers of threatened and endemic species, make the reserve an important biodiversity asset to the province. Its successful conservation relies on its protection, the management of its resources and infrastructure, and the support of its neighbours and the community living in their surrounds. 3.2 Objectives and strategic outcomes An objective has been identified for each of Ingwehumbe Nature Reserve key performance areas, which follow from the management challenges, issues and opportunities, and relate to the important functions and activities necessary to protect, develop and manage it effectively. The objectives have then been translated into strategic outcomes, which form the basis for the management activities and targets set out in the operational management framework, described in Section 6 below. Table 5 sets out the key performance areas, the objective for each key performance area and the strategic outcomes, required to realise the objectives.

4) ZONATION PLAN The purpose of the zonation of Ingwehumbe Nature Reserve is to control the intensity and type of use within it, in efforts to ensure the overriding goals of production and biodiversity conservation are met. On this basis, within some zones, the permissible intensity of use will be relatively higher than in others. Figure 12. Zonation plan for Ingwehumbe Nature Reserve. 4.1 Conceptual development guidelines 4.1.1 Limited use zone This zone is designated for areas in which activities are to be limited to low- impact ecotourism uses and conservation management interventions. Motor vehicle access into parts of Ingwehumbe Nature Reserve, for management purposes is allowed in this zone, together with visitor access to the camp. Controlled camping is allowed. Low level management infrastructure such as patrolling observation points will also be allowed in this zone. The objective of this zone is to enable access and usage of the nature reserve whilst limiting the impacts of this. 4.1.2 Moderate use zone This zone covers areas that encompass key zones for the development of management infrastructure and relatively high levels of visitor usage. I N G W E H U M B E N AT U R E R E S E R V E MANAGEMENT PLAN 28
Furthermore, this zone is designated for areas of relatively high vehicle usage such as for visitors travelling to and from the main lodge/s within the nature reserve. The objective of this zone is to accommodate lodge-style developments and to enable the development of operational management infrastructure such as stores, maintenance areas and staff housing within the nature reserve. Permissible activities for these two zones: • Development of lodges. • Development of roads infrastructure in compliance with environmental law requirements. • Maintenance of the main access roads through the nature reserve. • Development of the nature reserve’s park management facilities comprising infrastructure such as entrances, staff housing, offices, workshops and storehouses. • Grazing of livestock, at stocking rates at or below the commercial stocking rate. Non-permissible activities: • Introduction of non-indigenous grasses, trees or shrubs for landscaping purposes. • Ploughing of land. 5) ADMINISTRATIVE ST RUCTURE A recommended organisational structure for Ingwehumbe Nature Reserve is set out in Figure 13.

The management targets will form the basis for monitoring of performance in implementing the plan and are thus measurable. 6.1 Legal compliance and law enforcement Through the landowners of the biodiversity stewardship site, the management authority has been mandated to enforce laws related to the conservation of the site, which prohibit particular activities. In fulfilling this role, the managers of Ingwehumbe Nature Reserve will adhere to the following guiding principles: • All reasonable efforts must be made to ensure the effective conservation of biodiversity within and on the boundaries of the nature reserve. • Law enforcement efforts should be coordinated with the relevant authorities including the South African Police Service in addressing offences and breaches of the law. I N G W E H U M B E N AT U R E R E S E R V E MANAGEMENT PLAN 30
• Law enforcement at the site will be undertaken through surveillance, monitoring and appropriate reaction in the event of an offence. 6.2 Buffer zone protection and regional management In order to safeguard the biodiversity within the nature reserve and to counter any threatening processes or edge effects, appropriate land uses in the surrounds of the reserve should be encouraged. Actions may also be taken to secure the boundaries of the reserve through protected area expansion mechanisms and local planning tools. In ensuring the protection of its biodiversity, the following guiding principles will be adopted in terms of buffer zone protection and regional management: • Appropriate actions must be taken to manage threatening processes and edge effects on the nature reserve’s boundaries and beyond them. • The reserve’s managers will endeavour to assist the local and district municipalities in determining appropriate land uses and development strategies in the areas surrounding the nature reserve. The operational requirements for law enforcement, and buffer zone protection and regional management are set out in Table 6 below. I N G W E H U M B E N AT U R E R E S E R V E MANAGEMENT PLAN 31
