Media Release: Groundbreaking initiative launched to combat high risk environmental threats in the Garden Route

28 August 2025

A first-of-its-kind platform to combat primarily Invasive Alien Plants (IAPs) in the Garden Route was launched today during an engagement, chaired by Paul Gerber from the National Department of Forestry, Fisheries and the Environment (DFFE). Through this initiative, the Garden Route Environmental Forum (GREF) also joined hands with the Garden Route District Municipality (GRDM) and key partners to address some of the region’s most urgent environmental and wildfire risks, bringing together government, conservation bodies, and local stakeholders.

The key obstacle to achieving high-impact and effective results remains the lack of funding, which was one of the issues that cut across the board.

Cobus Meiring from GREF, said: “The drive to launch this platform is also rooted in past occurrences and helps prevent similar instances like the Knysna and Bitou wildfires of 2017 and the Outeniqua fires of 2018, where IAPs fuelled the intensity and spread of these disasters. Furthermore, rather than just sharing information, stakeholders involved in this platform will focus on executing tangible actions”.

“It is important to note that while post-fire rehabilitation has progressed, AIPs have re-emerged more aggressively, worsening the wildfire risk for the region and threatening the Garden Route’s biodiversity.”

The platform has set a bold interim vision: to reduce IAP coverage across the Garden Route by 30% by 2030. This will support biodiversity conservation, water security, and wildfire risk reduction.

“We cannot afford to lose further control of wildfires. IAPs are choking our rivers, threatening ecosystems, and putting lives, infrastructure, and local economies at risk. This platform is about coordinated action,” said Cobus.

According to Gerhard Otto, GRDM Head of Disaster Management, “We need to roll out block burning to achieve greater impact over the next two to three years. IAPs have already been flagged by the GRDM as one of the highest risks for the region and we need to focus on block-burning the highest risk areas.”

GRDM Fire Chief Deon Stoffels emphasised that, “fynbos fires are part of the natural cycle, but IAPs create unnaturally high fuel loads that make fires catastrophic.”

A Coordinated Effort for Risk Reduction

The multi-stakeholder Task Team includes DFFE, GRDM Disaster Management and Fire Services, local municipalities, CapeNature, SANParks, the Southern Cape Fire Protection Association, and several NGOs and research institutions.

Together, the team will:

  • Coordinate alien invasive plant management across administrative boundaries.
  • Strengthen fire management capacity through integrated planning and joint operations.
  • Support ecological rehabilitation in exit plantation areas (such as Buffelsnek, Bergplaas and Jonkersberg).
  • Explore leveraging technology like drone mapping, geo-referenced data, and machine learning for cost-effective clearing and monitoring.
  • Engage landowners and communities in coordinated clearance and fire mitigation efforts.

Stakeholders stressed that the funding challenge is immense. Clearing the IAPs between George and Nature’s Valley alone would cost R2.3 billion (2018 figures). This is far beyond individual landowners’ means. GRDM over the past few years submitted two multi-million rand funding applications of which none were approved; financial resources therefore remain limited.

Call-to-Action

The Task Team is open to consult with all stakeholders who play a role or is responsible for the management of IAPs, including private landowners. Participation is vital to ensure that IAP clearance takes place at an ecological and landscape level, not just in fragmented administrative blocks. More details about how to get involved will be communicated soon.

Next Steps

In the coming quarter, the sub-teams will be to “connect the dots” of what has been done so far, enforcement efforts, consolidate available funds and more.

18 September 2023 Media Release: Future water security in the Southern Cape must include innovation and best practice

Media Release: Future water security in the Southern Cape must include innovation and best practice

For Immediate Release
18 September 2023

“Water scarcity, changes in rainfall patterns, climate change, potentially restrictive water license regulations and proposed water quotas with far reaching impacts are all reasons why farmers and other water users are pushing the limits in terms of building new storage dams or enlarging existing ones or channelling water courses, often doing so without obtaining the necessary official permission required, and in the process expose themselves to costly litigation,” says Cobus Meiring of the Southern Cape Landowners Initiative (SCLI).

Globally agriculture is a major water user and so is mining, industry and human consumption which is rapidly on the increase and posing a complex water demand issue as urbanization world- wide accelerates along with changes in climate.

From an environmental perspective, ultimately ecosystems suffer the most as run- off water is dammed up for storage leaving rivers and streams starved of sufficient supply despite of legally determined minimum reserve flows to ensure their essential ecological survival, having dire impacts on estuaries, aquatic and marine life.

Technology plays a vital role in reducing water consumption on all fronts, and even if difficult to quantify exactly how much collectively it does make a huge difference as farmers invest in advanced irrigation technology, new generation taps and plumbing devices in new developments and permanent water restrictions in towns and cities across the board.

The impact of invasive alien plants in high value catchments is measureable and account for substantial water loss making their constant eradication and control vital. In addition, the prevention of water evaporation on a significant scale holds a key factor in stabilizing water levels in reservoirs globally, and although thus far not utilized on a grand scale, it is an exciting prospect to cover open water surfaces to suppress rapid evaporation rates as heat and drought waves takes effect.

Water management plans for industry designed to regulate, recycle and minimize water use, technology inventions in irrigation and public participation campaigns to reduce water use in cities all make a difference, and is bound to play a bigger role as water demand surges.

In recent times South African water conservation entities have developed floating panels designed for covering large reservoirs over life time periods and no doubt will become a standardized if not essential contributor to water management and preservation systems in years to come. Given the fact that water users dependent on storage dams require no EIA nor permission from water management entities to cover storage dam surfaces, it may well be an additional solution for water stressed entities globally.

Based in the Garden Route, the Southern Cape Landowners Initiative (SCLI) is a public platform for land owners and land managers focussing on invasive alien plant eradication, environmental management and water stewardship.

Media Release: Garden Route District Municipality applies for an Alien Vegetation Control Programme Grant

For Immediate Release
5 October 2022

The Garden Route District Municipality (GRDM) has applied for a grant, through the Western Cape Government Provincial Treasury, to reduce the fire risk and improve the water supply. The proposed project, budgeted at approximately R29 million, will include a coordinated alien invasive species clearing, ecological restoration plan and community training programme. It is planned for the various catchments and rivers/tributaries and their habitats within the region.

GRDM Executive Mayor, Alderman Memory Booysen says that if funding is approved, the project will contribute to the integrated development of marginalised communities through income-generating invasive alien vegetation clearing projects.

“The GRDM and partners also plan to grow the community’s skills by enhancing their knowledge about identifying alien vegetation and clearing it,” he said.

More benefits of the proposed project include:

  • Restoration of ecosystem functions (i.e., nutrient cycling, habitat value);
  • Protecting biodiversity;
  • Initiating regrowth of indigenous plants;
  • Reducing fire risks;
  • Increasing water security;
  • Erosion control;
  • Enhancing tourism potential;
  • Restoring of wetland and estuarine functions;
  • Enhance tourism potential;
  • Improving agricultural potential of land (grazing and crops);
  • Long-term conservation of the mountain catchments, rivers, wetlands, and remaining natural; and
  • Facilitate the establishment of a positive working relationship between local communities and local government.

A lot of invasive alien plants (IAP) thrive throughout the Garden Route and its seven local municipal areas. Projections indicate IAPs could double within the next 15 years if something isn’t done soon. Such plants pose a threat to biodiversity, water conservation efforts, agricultural management and fire risk management.

Managing IAPs is based on two fundamental principles – acting early and following up. This includes initial control to drastically reduce the existing IAP footprint; and controlling seedling, root suckers and regrowth. Finally, maintenance to sustain low and decreasing IAP numbers will yield more positive results.

Dr Nina Viljoen, Head of Environmental Management says many alien plants consume more water than local plants, depleting valuable underground water resources, which results in additional fuel for veld fires. “Lower slopes, river floodplains and forest and scrub vegetation are largely invaded by species such as Acacia mearnsii and Acacia melanoxylon, amongst others, said Dr Viljoen”.

Alien plant invasions are estimated to have reduced mean annual runoff in the major rivers within the district by almost 20% by 2007 (Le Maitre et al., 2013).
