If a tree stands in the forest and nobody knows where it is: Mapping trees in the MELNHE plots.
This document discusses using stem mapping to understand patterns of soil respiration. It notes that forest stands are about evenly split between trees associated with arbuscular mycorrhizae fungi and ectomycorrhizae fungi. Stands dominated by trees with arbuscular mycorrhizae are likely to have higher soil respiration rates, since these fungi promote more microbial activity in the soil. The study will identify tree positions, measure soil respiration data, and compare it to the dominant tree species in the stands.

- 1. Can Stem Mappinghelp understand patterns of soil respiration? Ben Lee Mentors: Mary Martin & Matt Vadeboncoeur • Mycorrhizae associate with almost all plants – Arbuscular Mycorrhizae (AM) – Ectomycorrhizae (EM) • Stands are about 50/50 • Stands dominated by trees with AM Fungi will likely have higher soil respiration rates – AM fungi promote microbial activity in the soil • Tree positions identified through the use of a hypsometer and a compass • Soil respiration data and dominate tree species will be compared
