Join Earthwise Aware (EwA) for an interactive walk to observe, document, and take part in shaping urban spaces that work with nature. Together, we will explore how design choices and climate pressures shape the ecological value of our everyday green spaces, and document habitat conditions using simple citizen science tools. Starting at the library lawn, we will examine spaces that appear green but often function poorly. Manicured lawns and sparse tree plantings may look inviting, yet they frequently support little biodiversity and can limit soil health and resilience. What makes a space truly nature-friendly? We will record what is present, what is missing, and what that tells us about ecological function. During the walk, we will: Observe and document plant communities and habitat quality Identify signs of low and high ecological function Compare conventional landscapes with more resilient plantings such as native beds or meadow patches Contribute real data that supports local ecological understanding and decision making This is participatory science in practice. Your observations will feed into broader efforts to track urban biodiversity and inform better land use choices. The program will meet outside the library in Joan Lorentz Park. Registration required. Rain date: Wednesday May 6
