Document Summary
37 - 40, 44 - 55, chapter 3, pp. A basic knowledge of the biological environment can go a long a way toward understanding and explaining human impact. The extinction of species (such as the passenger pigeon or ivory-billed woodpecker) or the endangerment of species (such as the northern cod) often occurs as a result of incomplete knowledge of ecology. Our understanding of the ecology of a particular system is often limited by a lack of quality baseline data. It cannot help us to not know what is in the forest that is being logged or in the river that is being dammed or diverted. This is the purview of landscape ecologists and other wildlife geographers. The northern leopard frog, a common breeder in southern ontario requires a wetland for breeding only. In fact it is likely to spend much of the spring and all of the summer foraging in grassland 100 200m or more meters away.
