Invasive species

Biological invasions are responsible for substantial biodiversity declines as well as high economic losses to society and monetary expenditures associated with the management of these invasions. The InvaCost database has enabled the generation of a reliable, comprehensive, standardized and easily updatable synthesis of the monetary costs of biological invasions worldwide. Here we found that the total reported costs of invasions reached a minimum of US$1.288 trillion (2017 US dollars) over the past few decades (1970–2017), with an annual mean cost of US$26.8 billion.

The NGC is designed for people with an interest in the utilization and conservation of our grazing lands, and a desire to learn the most current information on grazing livestock systems and their impact on our lands. The 2020 NGC was recorded and the videos are now posted.
