A Yosemite toad on a road. Amphibians and reptiles are particularly susceptible to negative effects of roads within their habitat. Many are slow moving, do not avoid roads, and are simply too small for drivers to see and avoid. During rains many amphibians travel long distances regardless of the presence of intersecting roadways.

Lionfish invasion (1985-2018). Lionfish invaded US Atlantic coastal waters, the Caribbean Sea, and the Gulf of Mexico with unprecedented, alarming speed. Though reports of sightings date back to the 1980s, it is only recently that the species has exploded in numbers and range.

A Berlese-Tullgren funnel system that is used for studying soil invertebrates. This laboratory technique causes soil invertebrates to move away from the soil surface as it is being warmed and dried by the lights above. The invertebrates are caught in jars of ethanol below the funnels, counted, and identified under a microscope.

Bromus Rubens (red brome) is an invasive annual grass that grows in warmer deserts of the Southwest U.S. It can carry fires in systems that aren't fire adapted, causing lasting damage to desert flora, as shown here in the Sonoran desert north of Phoenix, AZ.

Thinning rangelands by removing trees such as juniper is a common mangement action done across the intermountain west. The goals of this type of vegetation treatment typically are to increase forage and habitat for grazing animals, improve soil conditions, and/or reduce risks of catastrophic fire.

In 2018, USGS and partners completed an incredible feat against a harmful aquatic invasive species when over 240,000 pounds of invasive Silver Carp and Bighead Carp were removed from Creve Coeur Lake in Maryland Heights, Missouri.

Organ pipe cactus are rare in the Sonoran desert in the U.S. They can only be found in and around Organ Pipe Cactus National Monument, shown here. The distribution of Organ Pipe Cactus is limited due to lack of tolerance for cold temperatures. The biota of the Sonoran desert is particularly senstive to disturbance.
