ABSTRACT
Much of this handbook is concerned with how to take measurements once you are at a sampling site, a predetermined point in the landscape. Much of this chapter, however, deals with how the location of those measurement sites is determined. As will be discussed below, the problem of choosing the location of measurement points is one that occurs at several different scales. At one scale, we have to choose where the whole study will be located. At another, we need to choose where at an individual sampling site cores for soil chemical analysis will be taken. Somewhere between the two is the problem of choosing the sites themselves. While the argument gets a little more complex than this, the problem can be visualized as choosing the number and location of points in the study landscape at which the measurement protocols (described in subsequent chapters) will be implemented.
