Fifteen participants joined Sophie Barno on a salt marsh ecology walk at Marine Park on Sunday, September 24th. They observed the unique flora and fauna that distinguishes a salt marsh from other ecosystems. They discussed the benefits that salt marshes provide to humans such as flood mitigation, carbon storage, and pollutant filtration. Finally, the discussed how this ecosystem is threatened by sea level rise and coastal erosion because, while wetlands can grow and move inland with sea level rise, there is little land available for them to do so in NYC.
