The Influence of Swamp Size on Cypress Tree Growth Rates in Florida Swamps
This study investigates how the size of swamps in Florida (classified as small, medium, and large) affects the growth rates of cypress trees (Taxodium distichum). By sampling three swamps from each size category, the research measured water levels across 27 locations. The data were analyzed using statistical models, including Analysis of Variance (ANOVA) and F-tests, to compare the effects of swamp size on tree growth. The findings contribute to our understanding of wetland ecosystems and the importance of water management.

Data • Florida Swamps Classified in 3 Size Categories: Small, Medium, Large (Fixed Factor) • 3 Swamps sampled from each size type (Random Factor) • 27 locations sampled and water levels measured, in cm. • Yijk represents the water level for the kth location of the jth swamp within the ith size level Mean (SD) for the 27 locations for the 9 Swamps (Approximated from paper)
