00:00How invasive species are reshaping America's landscapes.
00:04A wild hog can turn a clean field into torn soil overnight.
00:09Across American forests, farms, wetlands, rivers and coastlines, invasive species dig,
00:15climb, spread and reshape the land around them.
00:19Wild hogs root through southern fields with strong snouts breaking soil, eating crops
00:24and leaving muddy scars behind fences.
00:27Nutria chew Gulf Coast marsh plants, turning grassy wetlands into open mud where water
00:32can wash soil away.
00:34Zebra mussels cling to boats, pipes, docks and lake bottoms, crowding native shellfish and
00:40changing clear freshwater systems.
00:42Asian carp surge through Midwestern rivers, leaping near boats while competing with native
00:47fish for tiny food in the water.
00:50Spotted lanternflies climb trees and vines in eastern states, feeding on sap and leaving
00:55sticky residue on bark and cars.
00:58Burmese pythons slide through Florida Everglades marshes, swallowing birds, raccoons, rabbits
01:04and other animals near shallow water.
01:06Invasive grasses spread across dry western land, giving wildfire more fuel when hot winds
01:12move over hillsides.
01:14Green iguanas dig burrows near Florida sidewalks and seawalls, weakening soil around homes, roads
01:20and canals.
01:22These invaders share one pattern.
01:24Fast breeding, human travel, warm weather, and disturbed land help them spread.
01:30When one new animal or plant takes over a field, river or forest, the whole landscape can change.
