A historic tree is a tree (or group of trees) that are at least 50 years old and share a significant event (or events) in a specific place in time. What is “significant” could vary according to the point of view, but the Texas Historic Tree Coalition often refers to historians, anthropologists, and other experts for recommendations. In essence, credible historic reference materials must be provided and historic references should be corroborated by a reputable source before TXHTC can pursue further investigation. Size, age, or a great story behind a tree, can also contribute to a tree's significance.
