Tennessee Tree Day
It’s that time of year again — time to reserve your trees for Tennessee Tree Day 2024. Reserve yours now and plan on picking them up on March 15th or 16th and planting them that weekend. Here are some special things to know about this year’s statewide native-tree-planting extravaganza:
- This is the 10th Annual Tennessee Tree Day
- You have more than 12 native species to choose from
- Plant at home, on the farm, or anywhere you have permission to plant
- You have more than 150 pick-up sites to choose from
- We anticipate planting our one millionth tree in 2024 — we want you to be part of this historic milestone. (We founded the Tree Program in 2007 with a goal of planting one million trees. You can help us cross the finish line!)
Marking points in time: The Hal DeSelm Papers

A life dedicated to the flora of Tennessee
Dr. Hal DeSelm clambered around the crest of Cherokee Bluff in the heat of a late Knoxville summer 22 years ago. The Tennessee River flowed languidly some 500 feet below. Beyond the river stood the campus of the University of Tennessee Agriculture Institute. The towers of the city center rose to the northeast beyond the bridges of the old frontier river town.
DeSelm was not interested in the views of the urban landscape below. He was interested in the native trees, shrubs, herbs and grasses that clung to the ancient cliffside with firm but ultimately ephemeral grips on the craggy soil.
The retired UT professor, a renowned ecologist and botanist who died in 2011, had been sampling the terrestrial flora of Tennessee for decades. The life-long project took on a new urgency in the early 1990s, when he accelerated his data collection in hopes of writing the authoritative guide to the natural vegetation native to the forests, barrens, bogs and prairies of pre-European Tennessee.
Between 1993 and 2002, DeSelm collected 4,184 data points from 3,657 plots across the state. Many of those plots have since been lost to development, highways, and agriculture, or overrun by exotic species, but he assembled an invaluable baseline of the native landscape. Many of the sites he recorded have since been lost to development.
