A section of the Parks Canada website is designated to outlining Aboriginal cultures and their relationship to the land and understanding of the cultural landscape.  This section of the website reads like a university paper (including academic sources) and contains a description of various aspects of the Aboriginal relationship to the land (i.e. differences between Aboriginal and Western worldview and Aboriginal views on environmental protection etc.).  There are no external links but the site does provide an email for comments about anything written in this section.  This actually provides a good introduction and overview that would be beneficial to anyone looking for a basic introduction regarding Aboriginal relationship to the environment.
