Comparison of Two Field Methods in a Scientific Report/Paper Format
Lab Exercise 9_ Comparing Plant Density and Dominance in an Upland Forest using Two Methods
Methods Summary
The objective of this field exercise is to compare plant density and dominance in an upland forest of the Northern Cross Timbers Ecoregion using two different data- collection methods.
The sampling area is 50 m x 30 m (see gridded sampling area table below)
We will compare the data using a plot vs. a belt transect method in the same sampling area.
Belt transect method
o Measure the diameter (cm) of every woody shrub and tree in the randomly selected belt transect below.
o Indicate if the woody plant is a shrub or tree, and if it is a red cedar.
