America's Most Wanted Invaders
Why it matters

Invaders cost America billions — every year

$21 billion
average yearly cost of invasive species in the U.S., 2010-2020 (up from $2 billion a year in the 1960s)
Fantle-Lepczyk et al. 2022, Science of the Total Environment 806:151318
$1.22 trillion
reliably documented cost of invasive species in the U.S., 1960-2020 - and the authors say that's an underestimate
Fantle-Lepczyk et al. 2022, Science of the Total Environment
$509 billion
of that cost hit agriculture - the hardest-hit part of the economy

What's inside

6 chapters · 30 invaders · 78 large-print pages

Every invader gets two full pages that answer the same questions in the same order: where it came from, how to recognize it, where it lives now (state map), the harm it does, what has worked and what failed, can you eat it, and who to call if you see one.

Waters & RiversFish, mussels and crayfish that ride boats, bait buckets and floods into our lakes and rivers.
Coasts & ReefsFrom Atlantic reefs to Pacific islands: invaders that came by aquarium, ship and fur farm.
Swamps & the SouthFlorida is ground zero. Escaped and released pets now hunt in the swamps and suburbs.
Forests & TreesTiny insects that arrived in wood crates and on shipments, and the trees they kill.
Farms & FieldsHogs, ants, beetles and ticks that cost farmers and ranchers money every season.
Cities & BackyardsThe invaders you may meet on the way to the mailbox, from rats to mosquitoes.
