Control and Management

Researchers from USGS-FORT and -WARC and University of Florida are collaborating on a long-term Burmese python research program in southern Florida to address management needs of partners and stakeholders throughout the Greater Everglades.

USGS-FORT in partnership with the University of Florida and two state agencies (South Florida Water Management District and Florida Fish and Wildlife Conservation Commission) have initiated a scout snake program to increase the ability to detect and remove Burmese pythons from the interior of the landscape.

The USGS National Wildlife Health Center (NWHC) conducts surveillance in wild birds to facilitate early detection and situational awareness for high consequence pathogens, including highly pathogenic avian influenza (HPAI) viruses.

The Coronavirus Aid, Relief and Economic Security Act (CARES Act) was signed into law on March 27th, 2020, to aid response efforts and ease the economic impact of COVID-19. The Department of the Interior received funds to “prevent, prepare for, and response to coronavirus, domestically or internationally including, “biosurveillance of wildlife and environmental persistence studies.” The USGS...

USGS researchers are working with the Monterey Bay Aquarium Research Institute to optimize autonomous, robotic samplers for detection of DNA fragments shed by biological threats (BT; invasive species, parasites, pathogens) in our nation’s waters. Finding DNA fragments (a method known as environmental DNA sampling) produced by an emerging BT in water is akin to finding a needle in a haystack—many...

Southeast Asia has long been the epicenter of AIV emergence. However, as demonstrated by H5NX, these viruses can quickly reach global spread and have significant impacts on poultry production and human health. We have two ongoing efforts funded by the National Science Foundation to help improve our understanding of AIV emergence, spread, and transmission in today’s rapidly changing landscape.

No current technology can specifically target Grass Carp Ctenopharyngodon idella for control within aquatic ecosystems. Other than TFM (3-trifluoromethyl-4-nitrophenol) for Sea Lamprey Petromyzon marinus control, available control chemicals used in aquatic invasive species management programs are non‐selective and typically applied throughout the entire water column, resulting in equal exposure of...

Wetland and Aquatic Research Center and Fort Collins Science Center are coordinating a long-term, landscape-scale Burmese python research strategy for South Florida.

WARC researchers are addressing an urgent need to identify specific habitat use of pythons on Key Largo, FL.

The USGS is adapting the Chinese Unified Method, a fishing harvest method that uses herding techniques and a variety of nets to drive fish and concentrate them into a concentrated area for capture, in the fight against invasive Asian carps. This “Modified Unified Method” incorporates adapted techniques and modern technology for efficient, mass removal of bigheaded carp in North American waters...

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.

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...
