Where are the biggest trees in America?

The state of Florida is well known for preserving its population of native trees, plants and animals. This southern state is made up of four different climatic zones; tropical rainforest, tropical monsoon, tropical savanna, and humid subtropical. The United States has some pretty big trees as well. This blog will tell you more about where big trees are in Florida and where are the biggest trees in America. Because of these zones the wildlife population in Florida is incredibly diverse, the temperature and growing conditions drastically effects plant-life from the North to the South and, comparatively, West to East. Florida’s hottest temperatures bring about tropical plants and trees, such as Orange, Lemon, or Palm Trees and in the North we find native , Oaks, Figs, Maples, Pines, Dogwoods, Plums, and Crape Myrtles.

Species that are native to a location are critical for the survival of surrounding ecosystems. Forests and trees are important for wild animals, other plants, and humans because they help clean the air by trapping debris in their canopies, provide food and shelter, and also prevent soil erosion. American Forests is a non-profit conservation organization that helps protect and restore healthy forest communities throughout the world, especially in the United States. They focus on critical issues with tree sustainability surrounding water, wildlife, climate change, recreation, and cities.

“Two mature trees provide enough oxygen for one person to breathe over the course of a year.”

Since 1940 American Forests has managed The National Big Tree program which recognizes and catalogs the largest of each tree species in the United States. Every year an updated list of our largest trees is published by dimensions of species, location, circumference, crown spread, height, and total points.

“One large tree can capture and filter up to 36,500 gallons of water per year”

The total points earned by each tree is calculated by this formula:

(circumference in inches) + (height in feet) + (1/4 of the crown diameter in feet)


  1. Name of the tree being nominated
  2. Circumference of the tree in inches, measured 4.5 feet above the ground
  3. Height to the nearest foot
  4. Average diameter of the canopy (crown) to the nearest foot
  5. Location of the tree
  6. Date measured and by whom
  7. Name and address of property owner
  8. Photograph of the tree and the date taken
  9. Description of the tree’s physical condition
  10. Number of tree rings

Here are a few noteworthy champs, the largest of their species

A few of the other biggest trees in America reside in many of our national parks and forests! A few noteworthy mentions are: redwood national park, yosemite national park, prairie creek redwoods state park, kings canyon national park which holds the second largest tree in the world, the General Grant Tree.
