Sonoran Desert Wildflowers and Invasive Species

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. Does this grass pose a threat to

Glacial fed alpine stream in Glacier National Park.

Scientists sample for alpine insects in streams like this near Blackfoot Glacier in Glacier National Park. Alpine streams environments in the northern Rocky Mountains are especially vulnerable to climate change due to rapid warming resulting in loss of glaciers and snowpack. Glacier National Park is iconic of the combined impacts of climate change and snow and ice loss –
