Sonoran dessert and the intruders
it is usually about non-native (invasive) species entering the Sonoran Desert ecosystem.
The Sonoran Desert is a large desert that stretches across parts of Arizona, California, Sonora (Mexico), and Baja California. It is home to unique plants and animals such as saguaro cacti, coyotes, roadrunners, and Gila monsters.
Who are the intruders?"Intruders" are usually invasive species—plants or animals that do not naturally belong in the Sonoran Desert but have been introduced there.
Examples include:
Buffalo grass – an invasive grass that spreads quickly and increases the risk of wildfires.
Red brome – another invasive grass that competes with native plants.
Feral pigs – can damage habitats by digging up the soil and eating native plants and animals.
Why are they a problem?
They compete with native plants and animals for food, water, and space.
They can destroy habitats.
Some invasive plants make wildfires more common, which can kill desert plants like the saguaro cactus.
