Progress Report GRRI Environmental Working Group – 10 August
DEA NRMP, Knysna Municipality, Eden District Disaster Management (and Municipality), the Southern Cape FPA, SANParks and Cape Nature, and several others, collectively address environmental rehabilitation in the burn scar.
1. Erosion control
Efforts and interventions to stabilize denuded landscapes around Knysna, Brenton and Belvidere continue.
A number of new sites have been added to the list since rain fell in the past seven days.
On Friday 4 August 26 millilitres of rain was recorded and fresh deposits of sand and soil were washed down the Brenton and Belvidere slopes.
At the same time, after a localized downpour, large amounts of soil washed down onto the N2 causing an accident, and road closure.
The N2 incident served as a clear example of what will happen in Brenton, should more than 20 millilitres of rain fall at any given time.
A total of 350 berms, spanning a total of 2100 meters have been installed.
1. Sites worked/ in progress
1. Sheer Cliffs (Brenton on sea)
2. Brenton Quarry
3. Featherbed Bay 1
4. Featherbed 2
5. Belvidere Estate/ railway line
6. Belvidere Heights
1. Clearing and stacking
2. Bio-degradable berms (referred to as sausages)
3. Bio-degradable blankets
4. Hydro seeding
The hydro seeder truck and equipment has arrived from the interior, and it has been tested and calibrated in Plettenberg Bay.
3. Labour force
DEA Working on Fire provides teams consisting of 45 workers, including a High Altitude Team (HAT).
A process to recruit a further 45 individuals, to assist with the hydro seeding process (scarifying of slopes), is under way.
Supervision, operational and technical support is provided by the Southern Cape Fire Prevention Association (FPA), under the auspices of the Project Management Unit (PMU).
The number of slopes and catchments which require intervention exceeds the available labour.
There is real threat that, should the area be exposed to rainfall exceeding 20 millilitres, vast amounts of sand and soil will be washed down the denude slopes.
A further concern is that the seed bank is being diminished as the slopes are stripped of significant amounts of (seed bearing) top soil.
Communication between the Disaster Management and participating entities takes place on a daily basis.
DEA has contacted GRR and requested that it make a concerted effort to lend the efforts of the Department more exposure.
Working on Fire has deployed a communication team to record efforts on the ground, and will distribute coverage to SABC and others on their media database.
The collective is in the early stages of discussions on a possible Open Day/ Media event in September.
The mayor of Eden District, as well as the private sector sponsors (Avbob specifically), indicated that they will visit the working sites on Wednesday 16 August (to be confirmed).
Articles have been noted in regional papers and announcements were made on radio stations.
Television coverage included MNet Carte Blanche and SABC Focus.
Pam Booth (Knysna Municipality), made a presentation on the fire and ongoing rehabilitation effort at the annual Fynbos Forum, held in Swellendam.
Ongoing social media is noticeable.
6. Landowner participation
Given the shortage of man power, landowners and their staff in Belvidere Estate are being trained on how to install bio-degradable berms.
Landowners in Buffeslbaai are also taking care of denuded dunes, and are installing stabilizing terraces made out of invasive alien tree trunks.
Landowners are using Vygies as a very effective and fast growing plant cover.
7. Stats on berms
Approximately 350 berms have been installed or have been delivered on site.
8. Partnership organizations
• Cape Nature
• DEA – Natural Resource Management Program
• Knysna Municipality
• Bitou Municipality
9. Weather advisory to landowners
Given the precarious state of the Knysna hills, the PMU will consider issuing an advisory to landowners whose properties are at risk of flooding and mud slides, ahead of rain storms.
10. Buffelsbaai on this day

The Southern Cape Landowners Initiative (SCLI), is a public platform for landowners and land managers who have an interest in the control and eradication of invasive alien plants. As part of its Water Stewardship Initiative, SCLI is piloting WEP systems in the Southern Cape. SCLI is supported by the Table Mountain Fund, an associated trust of WWF SA, visit www.wwf.org.za for more information.
