Progress Report GRRI Environmental Working Group 18 August
DEA NRMP, Knysna Municipality, Eden District Disaster Management (and Municipality), the Southern Cape FPA, WoF, SANParks and Cape Nature, and several others, collectively address environmental rehabilitation in the burn scar.
1. Erosion Control
GRRI Environmental interventions prevent tons of topsoil from washing down steep slopes into down stream properties in the Knysna area.
Stabilization of the environment is increasingly proving to be a vital component of the GRRI rapid(environmental) restoration response.
In total Knysna received between 27 mm rain 16th August – Diepwalle automatic rainfall sensor -to 38,2 mm – Knysna automatic rainfall sensor, causing significant soil displacement.
Erosion control focus, for the time being, will be focussed on where there is risk to human lifeand infrastructure.
Problems were most severe at Featherbed as well as Brenton on Lake, but pro-active soilremediation proved to be a tremendous help, at all the high risk areas where work has been done no major soil displacements occurred.
7500m2 of fibre blankets were installed

7. Data Management and Development of an Invasive Alien Plant Strategy:
Working Group defining the Burn Scar and finding erosion hot spots
GRRI Environmental Working Group has embarked with the development of a comprehensiveinvasive alien plant management strategy. All conservation entities will be consulted.
8. Norms and Standards:
