African countries will now be better able to guard against invasive pests that threaten their forests, sometimes from as far afield as North America, thanks to a new United Nations-backed web site launched to fight a danger that has grown seriously with the increase in trade, travel and transport. The site, created by African specialists at the initiative of the Forest Invasive Species Network for Africa (FISNA), is hosted by FAO. Features include information on new outbreaks of invasive pest species and woody species. It also provides references, publications and other links related to invasive species in Africa, those that are not native to a specific forest ecosystem, whose introduction does or is likely to harm the ecosystem.
