Typical mountain mixed coffee farm operation in Puerto Rico. Climate models project drying conditions in the US Caribbean which would have signficiant effects on moisture-sensitive species such as many endemic frogs. 

Ecosystems are changing at a rapid pace. It can be difficult to determine if a landscape is in need of restoration. In this photo of the spring wildflower bloom in the Sonoran desert, an invasive annual grass, Bromus rubens (red brome), is pervasive. Land managers have to make decisions about when, where, and how to intervene in a system.

Native fish species in Hawaii, such as this ‘O‘opu nākea, have amphidromous life cycles, spending part of their lives in streams and part in the ocean so they depend on connectivity from mountain to sea.

The project team for the Badlands National Park scenario planning effort included scientists from NPS, USGS, Wildlife Conservation Society, and National Oceanic and Atmospheric Administration.

The coastal bluff along East Cliff Drive in Santa Cruz, California are especially vulnerable to rising sea level during big storms. Sometimes even the rip-rap, put in place to protect roadways and homes, cannot protect the bluffs from erosion.
