Invasives
Many species introduced into new environments are unable to survive in their new surroundings. However, a percentage of these species are able to expand the area they infest and negatively impact the economy, human health or ecology of a region and are termed invasive. Habitat alteration and invasive species impacts have been the major cause of species extinctions over the past few hundred years, increasing the rate of extinction by about 1,000 percent. Although in the past, many of these losses have gone unrecorded, today, there is an increasing realization of the ecological costs of biological invasion in terms of irretrievable loss of native biodiversity and degradation of ecosystem functioning. While the underlying causes of invasive species threats are significant and global in nature, these threats can be effectively dealt with through collaborative efforts at regional and local levels, especially through prevention, early detection and rapid response.
