4.1. in seminar 6 we counted the number of stems (tree trunks) as a measure of species
abundance. instead of counting the number of stems, matlack (1993) used percent cover
when measuring shrub abundance. for woody plants, percent cover is an estimate of how
much ground surface area that the foliage of each species covers, as a proportion of the
total area being sampled. why would a researcher choose one method over the other?
what are the advantages of each method of determining abundance? (2 marks)

A researcher would chose percentage cover over stem count because percentage cover is a less time consuming process and easy to calculate in case of species having number of clones.

Advantages of stem count:

Advantages of percentage area count:

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
