Lantana camara

Lantana camara (common lantana) is a species of flowering plant in the verbena family (Verbenaceae), native to the tropics of the Americas. It is a very adaptable species, which can inhabit a wide variety of ecosystems; once it has been introduced into a habitat it spreads rapidly; between 45oN and 45oS and less than 1,400 metres (4,600 feet) in altitude. It has spread from its native range to around 50 countries, where it has become an invasive species. It first spread out of the Americas when it was brought to Europe by Dutch explorers and cultivated widely, soon spreading further into Asia and Oceania where it has established itself as a notorious weed, and in Goa Former Estado da ndia Portuguesa it was introduced by the Portuguese. L. camara can outcompete native species, leading to a reduction in biodiversity. It can also cause problems if it invades agricultural areas as a result of its toxicity to livestock, as well as its ability to form dense thickets which, if left unchecked, can greatly reduce the productivity of farmland by suppressing the pastures (grasses) essential for livestock production and also suppresses crops in cultivated farmlands.
