Biometry and soil protocols are a significant and essential consideration to implement
when conducting strategies to develop an advanced understanding of the tolerance of tree species
growing in Southeastern Michigan. Understanding the relationship between sediments, soils,
and tree growth on floodplains is an important issue to investigate to better understand the
impact of frequent river flooding. The parameters incorporated in
the investigation varied between soil pH, soil particle density, surface temperatures, and canopy
size. During the investigation period, rainfall and river water levels often varied due to heavy
precipitation events. A Pasco wireless weather sensor to record a variety of atmospheric
parameters. The GLOBE Observer App for trees was used to obtain tree height(s) and
circumference(s). This research suggests that of the trees and soil sampled, the physicochemical
environment of pH varies somewhat daily and seasonally. Soil porosity and density appear to be
heavily dependent on the distance between the tree and the Rouge River itself. Soil density is
important in determining how deep roots are grown on a floodplain. This research attempted to
determine how different floodplain locations affect soil pH, vegetation differences, and tree
tolerance to frequent flooding.
