Summary

Estimates of the biomass of the knees of baldcypress (Taxodium distichum), and oddly shaped, difficult to quantify vegetation components, can be critical to improve estimates of carbon stock in blue carbon assessments. To this end, tree metrics (e.g., density, height, biomass) were examined in 2004 at mixed baldcypress swamps across the Mississippi River Alluvial Valley (MRAV) from Illinois to Louisiana. Biomass of knees was estimated using the point-centered quarter method and volume/mass regressions calculated from measurements of knee height and diameter of the base of knees.

Purpose

The objective of this study is to estimate the percentage of above-ground biomass allocated to baldcypress knees using the point-centered quarter method in Taxodium distichum (baldcypress) swamps along the Mississippi River Alluvial Valley from southern Illinois to central Louisiana.
