Join Earthwise Aware for a thought-provoking workshop examining how land use and climate change influence the design, function, and future of urban green spaces. Starting at the library’s front lawn, we will explore how conventional designs can undermine biodiversity and tree health. What makes a space truly nature-friendly? Can a lawn, sidewalk, or plaza be transformed into habitat? We will compare low-functioning green spaces with examples of micro-forests, native plantings, and meadows. Along the way, we will observe seasonal changes in plants and wildlife through the lens of phenology, the study of nature’s calendar. We will also introduce simple participatory science tools that help monitor habitat quality, foster community engagement, and inform better decisions. Even a modest native plant patch can be a pocket of resilience. Come learn how to spot, support, and reimagine urban nature that works with the ecosystem, not just mimics it. The program will start with a workshop in the Rossi Room, then move outside to Joan Lorentz Park. Registration required.
