Invasive and Endangered

Invasive Spanish broom

Purpose or Accident? Spanish Broom was originally planted in California along mountain highways to help with erosion. Their seeds spread fast through erosion and any rain wash. The Spanish Broom prevents other native chaparral plants from colonizing.

Endangered California Condor

The California Condor is found in the chaparrals of California. It is endangered because of lead poisoning (Pollution in HIPPCO), shootings (Overharvesting in HIPPCO) , condors encountering electric power lines (Population in HIPPCO), and habitat loss (Habitat destruction or fragmentation in HIPPCO)

Animals in the Chaparral Biome

Cactus wren

The cactus wren has adapted to its hot habitat by shifting its foraging behavior according to the temperature

black tailed jackrabbit

The black tailed jackrabbit can regulate its body heat by increasing or decreasing the blood flow through its ears. Also the soles of a their feet are covered with fur. This cushions their feet on hard ground and insulates them from the scorching heat of the desert sand


The aardwolf has big ears to hear termites underground when it is hunting. The ears are also large to help the aardwolf lose body heat

Plants in the Chaparral Biome

Blue oak

Blue oaks are adapted to drought and dry climates. They can survive temperatures above 100° F for several weeks at a time

COYOTE brush

The leaves of a coyote brush are fire-retardant, meaning that they have a chemical makeup that reduces their ability to catch on fire. The leaves become fragrant and sticky with resinous oils on hot summer days. These oils are unappetizing and may protect the plant from being eaten.

common sagebrush

The sagebrush has a strong sweet smell and a bitter taste to prevent animals from eating it. The sagebrush survives its dry environment because of some of its adaptations. When rain is scarce its deep tap roots find water, but when it does rain it has shallow roots that are spread out below the surface to absorb the water
