rock elm (Ulmus thomasii)
Model Reliability: Current Distribution Only
Current Distribution Only
The model reliability (ModRel) for rock elm was too low (< 0.14), therefore only the current Forest Inventory & Analysis distribution is shown.

Regional Summary Tree Tables
Summaries for tree species are available for a variety of geographies, in both PDF and Excel format. These summaries are based on Version 4 of the Climate Change Tree Atlas
Interpretation Guide
Rock elm is very narrowly distributed (0.2% of area) and it rarely occurs in the northern half of the eastern US. As such, the model is unacceptable for prediction into the future. The species also shows a low adaptability to deal with the changing climate.
Family: Ulmaceae
Guild: pioneer, spring-dispersed, moist-site, intermediate shade tolerance
Functional Lifeform: medium to large deciduous tree
