Strandveld Vineyards Biodiversity Initiative Plan:

Alien plants eradication for biodiversityAs part of our Biodiversity plan we started a program of alien eradication in April 2005, which includes the following:

  1. Eradication of Port Jackson along the waterways (20ha)
  2. Eradication of pine trees in a rehabilitated potato field (59ha)
  3. Create a buffer strip around the vineyard blocks.

We are currently following up on the 3 year plan by eradication of any new Port Jackson trees.

Eradication of the pine trees has been very successful with almost no new re-growth. Buffer strips between vineyard blocks are flourishing with flowering fynbos and abundant bird and insect life.

The entire Cape Floral Kingdom is threatened by alien invasive plants because they compete with fynbos species for nutrients and water.

Alien invaders such as Port Jackson willow (A. saligna) and Rooikrans (Acacia cyclops) and other woody plants present mayor problems by decreasing natural water runoff by 50 %.

Above mentioned invaders are a major problem in coastal areas, especially here in the Strandveld. Pines (Pinus species) also present problems at all altitudes.
