It is difficult to distinguish experimentally between the use of landmarks and the development of a true cognitive map , e.g. Cassell's Natural History for Young People download pdf.

What precisely is it about the biotic community that makes it deserving of moral standing? Unfortunately, Leopold seems to offer no answers to these important questions, and thus no reason to build our environmental obligations around his land ethic.

These changes have had a dramatic impact on the ecology of the Colorado River. Clear water favors non-native fish species, scouring floods no longer clear the corridor of vegetation, and cottonwoods have trouble reproducing since they depend on floods to stimulate their seeds to sprout. In 1996, 2004, and 2008 the Bureau of Reclamation agreed to allow excess water from Lake Powell behind Glen Canyon Dam to flush the River in a controlled flood to help counter some of these ecological problems by mimicking natural seasonal floods , source: The Universal Natural History download epub The Universal Natural History.
