The ESA Annual Meeting is where scientific theory and practice come together

Every year, thousands of ecologists and environmental scientists from all over the world converge for a week of scientific presentation, networking, professional development, service and community-building.

This year, we’re taking it a step further. Our theme of ESA for All Ecologists is an expression of our commitment as a community to lift up, share and celebrate the important work done by all ecologists regardless of their occupation, industry or field of study. That we’re doing it at what’s historically our most popular meeting site is no accident, either—we plan on bringing together as many as 5,000 ecologists, the vast majority of whom are looking for new products, services, colleagues and employment opportunities.

We anticipate over 5,000 attendees in the historically popular location of Portland, OR. ESA holds their meeting in Portland, OR every five (5) years and in 2017 had 4,533 attendees. Promote your products, services, technology, equipment and literature to these scientists, researchers, educators, administrators and policymakers in the science of ecology and environmental science.

OOS 65 – Long-term Dynamics in Green Roof Ecosystems
Thursday, August 10, 2023 3:30 PM – 5:00 PM PDT Location: 251

Green roof (GR) ecosystems (roofs with plants and soil-like substrate overlaying a waterproof membrane) have arisen as a prevalent nature-based solution in cities worldwide, installed for their ability to provide much-needed ecosystem services including reduction of stormwater runoff, localized cooling, carbon sequestration, aesthetic enhancement, and biodiversity support. In the dense urban core, green roofs provide one of the few viable options for urban greening. The assumption on installing a GR is that the functions supporting ecosystem services will continue to be provided at a high level in perpetuity. It is known however that terrestrial ecosystems are dynamic over time due to (sometimes) predictable changes in soil and vegetation properties.
