The rate of recolonization by native plant species after the eradication of the invasive alien plant species (Lantana camara L.) at Valdezia, Limpopo

Invasive alien flora can overwhelm riverine network and modify the hydrology. Little is known about riparian invasive alien trees impacts on general ecology although invasive alien trees are by far the biggest threat to universally red- listed dragonflies (Odonata) in South Africa. Twenty- four permanent plots of 10 m2 each were constructed. Before removal, invasive alien species and native species present in the quadrats were counted and recorded. The invasive alien plants were removed by digging and uprooting with no use of chemicals. The difference was not significant when it comes to species diversity and richness before and after removal of Lantana camara in the study area. L. camara re- established in large numbers even after the treatment. The emergence of L. camara after the clearing is thought to be due to its ability to reproduce through the stem cuttings which might be lying on the ground, thereby reproducing via stem layering and from the seeds in the ground as some of the seedlings were seen being produced from the seeds.
