Conservation, in broad terms, has been a dynamic and nuanced practice throughout Mexican history. Nature conservation and protection include individual practices such as planting trees to protect watersheds, seasonal hunting bans, land set-asides such as national parks, and the ideas and values that shape these actions. Three broad eras are analyzed to provide a kaleidoscopic view of how some people living in Mexican territory have understood and acted for nature conservation. The first era, stretching from the pre-Columbian through the colonial eras, was characterized by an abundance of nature relative to people using it. The reasons for conservation were infrequent but did emerge, particularly in urban settings. The second era, the administrative era from the 1820s to the 1980s, included early national claims, revolutionary policies, and the reach of global institutions into domestic conservation policy. Nature’s limitations became apparent due to overuse and development which inspired formal responses to limit exploitation. The third era, from 1982 to the present, involves an age of abstraction where conservation has been reimagined for various purposes by a culture increasingly removed from an appreciation of the practical and aesthetic qualities of nature.
