Maple-leaf Oak
One of America’s rarest trees, maple-leaf oak is restricted to a handful of dry, rocky mountaintops in western Arkansas.

Maple-leaf oak occurs naturally only on a small number of Arkansas mountains, including Mount Magazine, where it grows on dry rocky upper slopes and ridges. Its leaves often have broad pointed lobes that recall a maple, but the tree’s alternate leaves, buds, bark, and acorns establish it as an oak. Taxonomic treatments once placed it as a variety of Shumard oak.
Restricted range makes location helpful, yet observers should not publish precise vulnerable trees or collect acorns and leaves. Photograph the crown, bark, multiple leaves, buds, and any fallen acorn from durable trail surfaces. Drought, severe fire, climate change, disease, and small population size can affect the species even inside protected landscapes.

Four checks for Maple-leaf Oak
- Begin at field distance
- Begin with a distant view of Maple-leaf Oak should support broad maple-like lobes on an acorn-bearing oak.
- Move to fine detail
- Look for require acorns and alternate leaves before settling on the identification; mountaintop restriction provides a useful cross-check together with mountaintop restriction before accepting the identification.
- Check ecological context
- Dry rocky upper slopes and ridges; leaves easiest from late spring through autumn.
- Leave habitat intact
- Read Maple-leaf Oak from canopy to ground, relying on fallen evidence instead of climbing or collecting.
Good to know
The tree’s scientific name and rank have changed as botanists studied its relationship to Shumard oak. That taxonomic debate does not change the conservation fact: the distinctive Arkansas mountaintop populations occupy an exceptionally small range.
