April is National Native Plant Month, and in this episode we talk with Sustainability Specialist Kevin Harrison and Paul Kovalcik of our Stormwater Inspection & Maintenance (SWIM) department, unpacking what defines a "native plant" and why they matter for water quality and habitat. We talk about how native species support pollinators, and why losing host plants can impact the entire food web.

We connect native landscaping to the Sewer District's stormwater management and stream-restoration projects, and explain how invasive species can take over when nothing has co-evolved to keep them in check.

Our guests offer tips on how to choose the right tree for the right place, when to plant, and why starting small is the best advice for building a low-stress native garden.
