Biogeography explains the distribution and diversity of living organisms on earth. For instance, different locations have different types of organisms living there due to environmental factors. There are two major factors that can determine where organisms can live, natural factors and human factors. Some natural factors include moisture, temperature, light, and soil. Humans can change where plants and animals live by relocating them into different environments. The migrated plants and animals can only survive if the environment has the necessary conditions to keep them alive such as food, water, light, or temperature. Although some plants can adapt to foreign environments and climates and they are known as Biomes.

Cherry Creek State Park has an abundance of life due to natural and human factors. The plants in this environment would be considered as mesophytes because they require a good amount of water but not an excessive amount. The temperature in summer is well beyond 50°F which allows plants to grow. With a good amount of plants and water, animal life can be supported as well. Deer, coyotes, rabbits, squirrels, and fishes are just a handful of the many different animals that populate this park.
