Table 1 Summary of physical environmental data for reference trees (Units SE, 3N) and trees in areas with prescribed fire in 2021 (Units 4, SW). Charted numbers are means based on the three study trees in each unit. Branches columns indicate the average number of branches between the pipes. Crown is measured from the lowest living branch and higher. Wetland distance is based on the distance to the nearest ephemeral marsh. The nearest neighbor is the distance to the single closest living tree >2 m tall. Trees within 5, 10, and 15 m were all counted if >2 m tall. The mean diameter at breast height (DBH) at 1.4 m is based on all neighbors counted within 15 m. Finally, the DBH of the study trees was measured at 1.4 m
