Invasive Alien Species Control Program in Malawi

Invasive alien species are plants, animals, pathogens  and other organisms that are not native to an ecosystem, which may cause economic or environmental harm or adversely affect  human health. 

PINUS PATULA (PINE) is Invasive in Nyika National Park and Mulanje Mountain Forest Reserve

Invasive alien species disrupt the balance of natural ecosystems.They out-compete native species, affecting biodiversity in ecosystems. In some cases, invasive alien species may reproduce with native species and alter the gene pool, leading to hybridization and homogeneity and reducing genetic diversity.Therefore, invasive alien species and their pathways must be properly identified, controlled and eradicated.

Black Wattle is invasive in Nyika National Park

Malawi has recorded between 31-69  invasive species but observation studies indicate the list could be up to 100. Invasive Alien Species in Malawi are introduced accidentally (food aid and planting material), intentionally (Landscape, fodder, fencing,agroforestry) and through tourism, trade and travel. Climate change has accelerated spread as temperatures in some areas are  becoming more favorable for invasive species than natural species.

Bracken Fern is not Alien but has become extremely invasive in both Mulanje and Nyika. This is our biggest problem species so far. 

 For the next 5 years, through my work as a Principal Environmental Officer at Environmental Affairs Department, I will be coordinating a 5 year project aimed at  prevent new invasions of Invasive Alien Species and reduce the current impacts of  existing Invasive Alien Species in two protected areas of Mulanje Mountain Forest Reserve in Southern Malawi and Nyika National Park in Northern Malawi. The project will strengthen  on-the ground management of Invasive Alien Species in the two protected areas and improve management of Invasive Species at National Level. 

All this is un managed pine growths. We want our natural vegetation back. 

I will be sharing the experiences of the project and I am looking forward to the changes our team will make in preserving the unique biodiversity in these biodiversity hot spots.  Below are the Invasive Species we will be eradicating and preventing their further spread in the two protected areas.
