- Abstract
- A series of permanent vegetation plots was established under the direction of Drs. Edward J. Kuenzler and Curtis Richardson. From 1985 to 1990, diameter at breast height measurements were made on all tagged trees. In 1990, cores were taken from randomly selected trees and the growth rings were examined to detect differences between the sewage-impacted and non-impacted years. The results of ANOVA models showed statistically significant growth differences among plots. Regression analysis revealed a pattern of increased tree growth immediately downstream of the sewage sprayfield. Black gum (Nyssa sylvatica var. biflora) showed the greatest increase in growth due to municipal sewage loading. Tupelo gum (Nyssa aguatica) and baldcypress (Taxodium distichum) showed considerably less growth changes due to municipal sewage loading. Brown Marsh Swamp downstream of the sewage sprayfield seems to function normally after the sewage has ceased flowing through this area.
