In March 2021, USGS researchers and partners conducted the first-ever Virtual Fish Slam. The bi-annual Fish Slam event helps monitor new introductions and document range expansion of known non-native freshwater fishes.

Using temperature, species occurrence, field-based freeze damage data, and regression analyses for 84 invasive species, researchers at WARC are quantifying the species-specific relationships between minimum temperature and plant presence.

UMESC supports Federal and state management agencies in their battle against invasive carp in the United States by conducting research, monitoring fish, and developing decision support tools. The Chinese Unified Method is a fish harvest method that uses herding techniques and a variety of nets to drive fish and concentrate them for capture. UMESC supported the development of the “Modified Unified...

Four types of invasive carp are currently found in the United States: black, grass, silver, and bighead carps. These species are fast growing, prolific feeders that out-compete native fish species and drastically alter the natural ecosystems they invade. To prevent the spread of invasive carp into the Great Lakes, the multi-agency Asian Carp Regional Coordinating Committee (ACRCC) implements...

Research on Guam has led to development and validation of numerous effective control tools, including the advancement of reptile control to support native species recovery.

WARC researchers are performing visual encounter surveys and passively capturing Cuban treefrogs to remove as many of the invasive anurans as possible.

ʻŌhiʻa ( Metrosideros polymorpha) is the dominant tree in Hawaiian forests, but Rapid ʻŌhiʻa Death (ROD), a newly emerging disease that stands to cause high mortality of this ecologically important tree, may lead to invasions by exotic plants as gaps open in the forest. To better understand if planting of ʻōhiʻa seedlings can be used as a restoration tool, we investigated the survival of ʻōhiʻa...
