It’s arbor week from 1 to 7 September in South Africa which is a great opportunity to place a spotlight on our unsung heroes – indigenous plants and trees. Indigenous plants or trees or those native to an area like South Africa and are important for an area’s ecosystem by providing many benefits. South Africa is renowned for its rich natural diversity and plant life so why not play your part in conservation by planting indigenous plants this year.
Indigenous vs. exotic plants and trees
Indigenous plants are found naturally in a particular area whereas exotic plants come from a foreign regions like overseas. Examples of indigenous South African trees include acacias, baobabs or even, our national tree the Outeniqua yellowwood. Although exotic trees can be beautiful, like the stunning Jacaranda tree, they could have a negative effect on South Africa’s local ecosystem, because they:
- require more water which puts a strain on the indigenous plants around them
- are prone to infestation
- die out easily
- can cause subsidence – a problem occurring where the soil beneath the ground becomes uneven which could potentially ruin structures in an area such as pavements and sidewalks.
Benefits of planting indigenous plants and trees
On the other hand, indigenous plants offer several benefits because they:
- improve soil quality by encouraging water retention, and preventing water run off
- maintain the local ecosystem by providing food and shelter for local animals
- are lower maintenance than exotic plants and trees
- contribute to the conservation of our natural diversity
