Learn to plant and maintain strong, healthy trees that will thrive for generations.

Introduction to Heritage Oaks

Learning Objectives

Students will be able to:

  • Understand that some oaks are very old.
  • Understand that oaks have been important to Californians throughout California history.

Time: 30 minutes


For each student:


Distribute, read and discuss Heritage Oaks.

An old oak tree may have a circumference of 252 inches! Have students measure the distance from finger to finger with arms outstretched (for most people this distance is equal to height) and do the math to determine how many students will need to join hands to approximate the circumference of an old oak. Similarly, oaks may grow to be 100 feet tall! Measure out 100 feet and have students line up to approximate the height of an old oak.

Going deeper:

  • Use the Internet to research the height and circumference of other tree species (try redwood) and use students to approximate those measurements.
