Biodiversity and Human Health Benefit from Invasive Species Removal (Jun 13, 2017)

Island Conservation.

Restoring islands through the removal of non-native invasive mammals is a powerful biodiversity conservation tool. This new study now shows that human communities on islands could benefit from restoration actions, which can potentially reduce or eliminate the burden of diseases transmitted to people by invasive species. Simply put, removal of invasive species can benefit human health in addition to ecological health.

Chinese Privet, Arthropods, and Bees (Apr 8, 2021)

USDA. FS. Southern Research Station. CompassLive.

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.

Economic Impact of IAS in the Caribbean: Case Studies (Apr 28, 2015)

CAB International.

To date no studies have been undertaken on the costs and benefits of IAS management in the Caribbean. This may partly explain why there has been negligible funding to combat the onslaught of these exotic species in the region. As a result it was decided to provide individuals involved in the UNEP-GEF Project, "Mitigating the Threats of Invasive Alien Species in the Insular Caribbean" with training and an opportunity to undertake Cost-Benefit Analyses (CBAs) on some selected IAS. The CBAs undertaken and reported in this publication clearly demonstrates that the benefits of managing IAS outweigh the costs.

Economics of Invasive Species (2021)

USDA. Forest Service.

While the subset of introduced species that become invasive is small, the damages caused by that subset and the costs of controlling them can be substantial. This chapter takes an in-depth look at the economic damages non-native species cause, methods economists often use to measure those damages, and tools used to assess invasive species policies.

Environmental Protection and Plant Health: A New IPPC Factsheet Explains the Link (Feb 2019)

UN. FAO. International Plant Protection Convention.

You cannot protect the environment without also safeguarding plant health. When plant pests and diseases spread into new areas they seriously damage entire ecosystems, putting at risk biological diversity and the environment itself. Tiny and lethal at the same time, plant pests and invasive alien species have been recently identified as the main driver of biodiversity loss. Pests are also responsible for losses of up to USD 220 billion in agricultural trade each year and the loss of 40 percent of the global food crop production. Climate change is making the situation even worse. It is changing the life cycle of pests – sometimes increasing the number of yearly generations - and creating new niches where they can thrive. For more information see the IPPC factsheet "Plant Health and Environmental Protection (PDF | 1.22 MB)".

Government of Canada Releases Socio-Economic Study on the Risk of Grass Carp to the Great Lakes (Mar 13, 2019)

Government of Canada.

Grass carp, one of four species of Asian carp, has the potential to disrupt the Great Lakes ecosystem and economy unless their spread is stopped, according to a report released by Fisheries and Oceans Canada with support from the Great Lakes Fishery Commission and the Ontario Ministry of Natural Resources and Forestry. The socio-economic study concludes that, in addition to the significant ecological threat that is posed by the presence of grass carp in the Great Lakes, there would also be economic, social and cultural ripple effects.
