An ecological analogy for retail:
Many of the plants we call weeds originally evolved in tough conditions, where there is annual glaciation, periodic flooding, or severe fires – extreme events that leave exposed, bare earth. It’s in these devastated conditions that our weeds are at home. They germinate first and grow the fastest. And through these characteristics they have found important roles in re-establishing healthy ecosystems… Once the weeds are established, longer-lived plants, less adapted to disturbance, germinate and the process of succession begins. The process may end in a grasslands, woodlands or forest, depending on the soil and climate. Indeed, the weeds create the conditions of their own inevitable demise – inevitable unless of course the disturbance recurs.
The “weedy species” that so many bemoan, the token dry-cleaners and fast-food joints that sprout in brand-new buildings, are one key to building a retail market. Over time, better adapted shops will take root — and given enough stability, species will evolve into very specific ecological niches. These new species will both adapt to their environment, and also change the environment around them. The key is to give the habitat time to evolve by avoiding excessive disturbance — a condition ecologists call “disclimax.”
Cultivating biodiversity requires striking the right balance between stability and renewal. The goal should be less to conserve individuals than to maintain the health of overall communities, to not seek out stasis forever but to manage change for the long term.
Gradual change within human communities also helps to sustain and build linkages, according to a paper by sociologist Katherine King: “A gradual pace of redevelopment resulting in historical diversity of housing significantly predicts social relations.”
