What Is a Biome?
A biome is a large geographical area characterized by specific climate conditions, plant communities, and animal populations. Biomes are distinguished by their unique climate patterns, soil types, vegetation, and wildlife. They can span vast regions and often contain numerous ecosystems within them.
Understanding biomes helps us recognize the interconnectedness of life and the environment. North America, with its varied climate zones, hosts multiple biomes, each supporting distinct ecosystems and biodiversity.

Vegetation
- Tallgrass and shortgrass species
- Wildflowers and herbs
- Few trees, mainly along water sources
Wildlife
- Bison
- Prairie dogs
- Coyotes
- Grassland birds like hawks and meadowlarks
Conservation Concerns
Much of the original grassland has been converted to agriculture, leading to habitat loss and species decline.
---
Desert
Overview
North American deserts include the Mojave, Sonoran, and Great Basin deserts, mainly in the southwestern United States.
Climate
- Extremely hot temperatures during the day
- Cold nights
- Very low precipitation
Vegetation
- Cacti such as saguaro and prickly pear
- Shrubs like creosote bush
- Succulents and drought-resistant plants
Wildlife
- Rattlesnakes
- Lizards
- Jackrabbits
- Roadrunners
- Coyotes
Adaptations
Plants and animals have evolved to survive extreme dryness and temperature fluctuations.
---
Chaparral
Overview
Found along the California coast and parts of the southwestern US, chaparral is a biome characterized by dense, spiny shrubs.
Climate
- Hot, dry summers
- Mild, wet winters
- Fire-prone environment
Vegetation
- Evergreen shrubs and small trees
- Drought-resistant plants
Wildlife
- Mule deer
- Coyotes
- Various bird species
- Small mammals and reptiles
Human Interaction
Frequent wildfires shape this biome; conservation efforts focus on fire management and habitat preservation.
---
Tropical Rainforest (in parts of southern Florida and Hawaii)
Overview
While not extensive, some regions like southern Florida and Hawaii feature tropical rainforest biomes.
Climate
- Warm temperatures year-round
- High humidity
- Heavy rainfall
Vegetation
- Dense, layered forests with tall trees
- Epiphytes like orchids and bromeliads
- Rich biodiversity of plants
Wildlife
- Exotic birds
- Insects
- Reptiles and amphibians
- Endemic species unique to the region
Significance
These biomes are biodiversity hotspots and vital for ecological balance.
