Chinese privet (Ligustrum sinense) is one of the worst invasive plants in the South. It dominates the shrub layer and often becomes the only shrub underneath trees, especially in streamside areas. But insects and spiders living in fallen leaves and leaf litter were not affected by a privet invasion in Georgia, as a recent study shows.

Research led by Queen’s University Belfast has shown that invasive species, such as the grey squirrel, European rabbit and Japanese knotweed, have cost the UK economy over £5 billion over the past 40-50 years. This is one of the highest totals in Europe. Invasive species, those introduced and spreading outside of their native range as a result of human activities, are a growing threat to environments worldwide. Environmental impacts of invasive species, one of the main causes of biodiversity loss, are well-studied. However, few studies have summarised their economic impacts. This study is the largest and most up-to-date combination of economic costs of biological invasions in the UK. The results have been published in the journal NeoBiota.
