Lawn (Re)Disturbance Laboratory:
Unearthing to Rewild, Remember, Look Forward
*Season 1 pilot project is taking place in institutional and residential lawns throughout the city of Troy, NY in Spring-Fall 2018*
“Pioneer species” are those plants that respond to disaster and disturbance, sprouting rapidly in bare, exposed or otherwise de-vegetated earth to jumpstart the process of ecosystem recovery. Large-scale events like earthquakes, floods, and landslides can churn up soil, exposing it to light, warmth, air and moisture. These ingredients unlock latent energy in the living soil seed bank- seeds that may have been dormant for years or even decades spring into action, providing the basis for ecosystem recovery and restoration.
LAWN (RE)DISTURBANCE = SOIL SEED BANK REAWAKENING
What seeds are hiding, dormant in the soil, beneath the myriad institutional and residential lawns of Troy? By removing 1 x 1 meter patch of lawn, we hope to find out!
Often labeled as “weedy”, many of the plants that emerge from disturbances produce relatively large numbers of seeds that have a long shelf life. This means they can stay dormant in the soil for many generations until the right kind of disturbance occurs, at which point they sprout and grow rapidly, stabilizing the soil and generating habitat until slower growing species arrive. What species does the city of Troy have waiting in the wings? Maybe a wildflower that was common in 1600 but we never see anymore? Maybe a medicinal herb that was brought by an immigrant from Europe or Asia two hundred years ago? Maybe a dandelion seed that was buried thirty years ago when the foundation for a new apartment building was excavated? Let’s find out!
Through both in-situ and lab-based disturbance and germination tests across a variety of heavily human-impacted landscapes, from long term turf grass monocultures to abandoned industrial sites, this art-ecology experiment will uncover the hidden power of past seed burial for future rewilding in the face of a rapidly changing climate.
Publicly visible test plots will be accompanied by educational information about wild urban plants and city ecology, and results will be shared with the community through group fieldwork days, public presentations and publications, and art workshops and exhibitions.
Below: 1 x 1 meter test plots are being established in the landscape and observed over the growing season.
