For millennia, people have brought plants and animals to Zanzibar  from all over the world - many now established as important long-standing staples of diet, culture and landscape. 

Yet a few of these introduced species have had a less benign impact on the ecological landscape and have made themselves a little too much at home. They don't just breed well in wild spaces, they actively displace existing wild species and may even take over completely, to become pests of field and forest.

These are not friends to our wildlife gardens, and are best removed. We have compiled a list of the worst offenders that we recommend removing as thoroughly as you can. Lest they become the only life left. less ↑
