Development leads to introduction of alien trees

Looking at the place behind the country’s main supermarket at the Mall, alien trees have grown in recent years. Experts from the Forestry Department in the Ministry of Environmental Affairs and Tourism painted a gloomy picture about the presence of alien trees. 

Senior Forest Officer, Solomon Gamedze indicated that there were measures that were being taken to try and address the challenges faced by the country. Gamedze said trees is locally known Gwayana or its known as Bug Weed, another invasive plant is Lantana which is popularly as Mehlo akati has been spotted in wetlands. 

A new project is currently under construction in Malkerns where a village supposed to be known as Umvangati Village. The name of the village came after a lot of lot these trees grew in the vicinity of the area.      

He attributed the invasion to the destruction of natural trees that were previously found along the banks of the Mbabane River. Uncontrolled grass fires have also contributed to the increase of alien plants. Institutions like the University of Swaziland have come up with an initiative that has seen them growing some indigenous trees just before Mafutseni. This was the brainchild of former vice chancellor Professor Lydia Makhubu who authored a titled Traditional Medicine and Healing.

A wild fire act needs to be looked into because the act has been around to over 60 years and this was because in recent years the country has seen a number of communities burnt by uncontrolled grass fires. Wattle trees have not been spurred because of the advent of companies producing charcoal. Burnt roots of some grass find themselves exposed to soil erosion whenever there are heavy floods in areas that have been burnt before the first rains.    

Measures are currently under way to ensure that companies in the business of making charcoal were under the watchful eye of the forestry department.
