- You wish to determine the abundance of the state- and federally-endangered Prairie Fringed Orchid (Platanthera lecuophaea) in a local prairie. (a) The prairie is approximately 100 acres of relatively flat terrain. Considering the “basic” sampling strategies, what might be a good sampling design (can just give the name)? Why? (b) You decide also to evaluate the abundance of the orchid in another prairie. The second prairie is of similar size but has a hilly terrain. What might be a good sampling strategy? Why?SAMPLE EXERCISES: Calculate for the Diversity Indices of the different communities given below using PAST. Relative abundance, however, need to be calculated manually.Which of the lab field techniques would you use to answer each of the following questions? Answer choices on bottom A-E.
