Hi Spotters,

Having trouble identifying an invasive species?
Well then take a look at our iNaturalist guide to Invasive Species in South Africa ( https://www.inaturalist.org/guides/6922 ). This guide lists all invasive species as listed in the National Environmental Management: Biodiversity Act, 2004 (Act no. 10 of 2004): Alien and Invasive Species Lists, 2016.

Have a great time spotting!

PS: we are removing our project https://www.inaturalist.org/projects/invasive-species-in-south-africa and transferring everything here. It will vanish soon, but please dont use it in the meantime.

Species that do not occur in southern Africa naturally.

Also use this tag for species that have been moved locally outside of their ranges.

The secret is to remember that you cannot use Alien without specifying a region. Thus the Outeniqua Yellowwood is alien to the Cape Peninsula, and the King Protea is alien to the Grasslands. Both are not alien to South Africa or southern Africa or the Western Cape.

Aliens can be passive, ruderal (invading croplands, pastures, gardens and disturbed areas) or invasive (invading natural veld).

Aliens can be good or bad, weeds or welcome. Some can be ecosystem transformers, changing veld from one state to another.
