It’s called “Biological Invasion Costs”—the price tag on dealing with invasive species—and simply put, it’s a lot of money. The National Invasive Species Information Center of the US Department of Agriculture (USDA) shares some gargantuan global figures.
Worldwide, since 1960, managing biological invasions has cost about $95.3 billion.
During the same period, the damage cost of the invasions was more than $1.13 trillion.
Like most everything else, invasion-associated management and damage costs are rapidly rising.
Proactive, pre-invasion management spending is 25 times lower than post-invasion management costs.
Countries all over the planet are declaring a National Invasive Species Awareness Week. In the US, it was February 28-March 4.
There are more than 6,500 invasive species established across the United States.
