CHAPTER 7 : MEASURING POPULATIONS OF SESSILE ORGANISMS - PLOTLESS SAMPLING FIELD TRIP: Wear slacks or jeans and sturdy shoes. Bring water and a snack. Bring sunscreen and a hat. We will meet in the lab to collect our gear. DO NOT BE LATE! Transfer sample site locations from Table 6- 1. Table 7-1: Sample site coordinates. Quadrat 1 2 3 PURPOSE: In this field exercise you will learn how to use a plotless (or quadratless) sampling technique. Then you will compare and contrast the plotless to the quadrat method. We will use the same sites as with the quadrat technique Plotless sampling techniques are those which utilize measurements of the distances of organisms from randomly chosen points, i.e., they do not necessitate setting up quadrats. They are used to sample characteristics of stationary populations. They are best adapted for sampling communities in which the individuals are widely spaced such as shrubs, trees, sessile marine animals, and the nests, mounds and burrows of insects, birds and mammals.
