From Nautilus: Your legacy on earth may be a plant.
Most people don’t realize how easy it is, when it comes down to it, for almost all signs of their existence to be wiped from the landscape. Fields turn into forests in less than a generation, if properly neglected. Houses are overtaken with creepers and birds’ nests and their roofs grow mossy and sag groundward after enough heavy rain. Within ten minutes’ drive of our house, there were no fewer than five home sites that had gone to seed, and sometimes to earth, with nothing left but a foundation and thousands of daffodils.
This last detail turns out to be a telling sign of former habitation. “If you find daffodils in a wild area, you can usually find chimneys,” says Robert Warren, an ecologist at Buffalo State University. Warren lived for years in North Carolina, another place where daffodils are thick where there used to be homes—the flowers just keep going on their own, for decades after they’re no longer tended. The old residents “got them through the Sears-Roebuck catalog—the bulbs,” says Warren. When he goes hiking, he likes to try to read the landscape, looking for signs of an area’s history in the vegetation. [continue]
Wow, what a cool article.
