River Rehabilitation helps the environment

Ecosystems can once again thrive through the act of river rehabilitation. According to the Conservation of Agricultural Resources Act, 1983 (Act No 43 of 1983) certain species of trees need to be removed as they are not indigenous to South Africa. As these invasive trees consume much more water than our own indigenous trees, they pose a problem to the ecosystem they exist in. They negatively impact on the biodiversity within our country as they transform grassland and fynbos into a dense land filled with invasive trees. They compete directly for precious resources and ultimately transform the land.

We exist to provide an eco-friendly and total solution to this problem. Africa Biomass Company assists in the removal and recycling of these invasive alien trees in the riparian zones. The trees that are removed are listed in the legislation, in either Category 1 or Category 2 as plant invaders.

Category 1a are invasive species which must be tackled and eradicated where possible. Category 1b are tree species which should be controlled, removed, and destroyed. Landowners who have category 1b invasive species on their land are obligated to have such plants removed and furthermore controlled by ensuring they are not reintroduced back into their land.

Alien invasive trees are removed and, by using Bandit's horizontal grinders, recycled into usable wood chips, which are then used as biomass in Agri-industrial applications to generate heat or electricity.

Alien invasive trees that Africa Biomass Company removes & recycles

The following species recycled by Africa Biomass Company are either listed as Category 1 or Category 2 alien invasive trees:

  • Rooikrans
  • Black Wattle
  • Beefwood
  • Eucalyptus

River rehabilitation exists in order to restore a river and the surrounding area to its natural or historical condition. ABC will come in when the river is in a degraded condition due to alien and invasive trees or shrubs consuming all the natural resources that our indigenous species rely on.

When alien invasive overgrowth exists, the loss of biodiversity occurs as the plants and animals who rely on the river system to survive either migrate or die out. This causes a disruption to the ecosystem, water levels and the basic health of the river. This can affect the area not only from a sustainability standpoint but economically and socio-economically too.

As rivers are vital sources of water, habitats and biodiversity and should be protected at all costs. Which is why we offer our services to national and local authorities in their quest to do so. We take the utmost care to remove alien trees and plants without damaging the land or indigenous trees, and returning valuable mulch to the system, which can assist with root and vegetative growth of indigenous plants in riparian zones.

Impact of removal of alien invasive trees on bees

Through the obtaining of government tenders, the area of alien invasive trees that needs to be removed is demarcated. Africa Biomass Company strictly follows these instructions set out in tenders, therefore the impact on bees by removing alien invasive trees is low or even zero. Our services are bee friendly.
