Black Wattle

The Black Wattle is an invader specie that was introduced to South Africa from Australia. The first Black Wattle was planted in 1928 and it was hoped that it would provide fuel, building materials, and shade In the early days the Black Wattles were also grown in a controlled environment to harvest its tannin. Unfortunately in later years they were allowed to spread through South Africa like wild fire.

Unfortunately it is estimated that invading aliens cover 10 million hectares of land in South Africa and, each year, use 3.3 billion cubic metres more water than native vegetation. In a country with acute water shortages the Black Wattle has been declared an invasive alien plant and is one of the species that the "Working for water" project is trying to eradicate.

  1. It is such pity that they have become invasive as it is such a lovely tree.

  2. Odd looking plants. Too bad it cannot be used for its original intent.

    So where does one from SA go on holiday? Where ever it is, have a very safe trip and have an awesome time. I'm sure Santa will find you for your deserved gifts. I hope you, your lovely wife, Drama Princess and Chaos Boy all have a very Merry Christmas and a very happy New Year!

  4. Those bean pods remind me of our Mesquite. Invasive species do tend to out compete the natives. I wish this project well.
