Areas like this tidal freshwater swamp, along the Pocomoke River in Maryland, provide important ecosystem services including improving water quality by trapping watershed sediment before it reaches the Chesapeake Bay. However, a sediment shadow along tidal rivers may limit their resilience to the impacts of sea level rise.

A rainbow trout rests among cobble substrate in Panther Creek downstream of Big Deer Creek, central Idaho. Panther Creek was severely damaged by heavy metals released from mining and milling activities at the former Blackbird Mine, and water quality in this section of the stream was acutely lethal to fish as late as 1985.

Nestled away in Reston, VA on 105 acres of land, the USGS headquarters was dedicated on July 12, 1974. The building houses over 2000 employees and offers guided and self-guided indoor and outdoor tours to the public.

Many species of Hawaiian honeycreepers have persisted into the 20th century because high elevation rain forests on the islands of Kaua’i, Maui, and Hawai'i are cool enough to limit transmission of introduced avian malaria (Plasmodium relictum).
