Science and Products
Biology, Impacts and Control of Invasive Reptiles in the Everglades
Invasive species are considered to be second only to habitat degradation in terms of negative impacts on the Earth’s ecosystems, and our scientists make up a significant proportion of the global expertise in the rapidly-growing problem of invasive reptiles.
Ecology and Management of Invasive Riparian Plants
Due to high rates of disturbance and human activity, streamside or “riparian” areas are prone to colonization and spread of invasive plants. In the western United States, hundreds of thousands of riparian acres are occupied by the invasive shrubs/trees tamarisk and Russian olive, as well as numerous exotic herbaceous plants. Our work focuses on understanding the factors driving the...
USGS Everglades Research Offices - Florida
The Daniel Beard Center in Everglades National Park provides the base for most of the field work done on the control of invasive reptiles by USGS Fort Collins Science Center staff. The team works in Everglades National Park, Big Cypress National Preserve, Crocodile Lake National Wildlife Refuge, and other parts of the Greater Everglades Ecosystem focusing on, among other species of concern,...
USGS Brown Treesnake Laboratory and Rapid Response Facility - Guam
USGS scientists and staff associated with the Brown Treesnake Project are co-located at the Guam National Wildlife Refuge at the northern end of Guam in the western Pacific Ocean. Project staff work on developing and testing control tools for invasive brown treesnakes, as well as understanding their impacts on Guam's ecosystems. Project staff also lead the multi-agency Brown Treesnake Rapid...
Ecology and Control of Invasive Reptiles in Florida
This project involves ongoing development of tools for the detection and capture of invasive reptiles in Florida, with an emphasis on Burmese pythons (Python bivittatus) and Black and white tegu lizards (Salvator merianae). The goals are to reduce the risk of reptile invasions in high-value resources such as Everglades National Park and the Florida Keys, to access early detection methods of...
Brown Treesnake Rapid Response Team
Brown Treesnakes continue to cause major problems for the ecology, economy, and quality of life on Guam. Our scientists conduct research on this snake species, including control tool development and testing, ecological impacts, and early detection methods. We hold Brown Treesnake Rapid Response Team training courses on Guam throughout the year to develop the skills needed to effectively...
Control and Landscape-Scale Suppression of the Invasive Brown Treesnake
The Brown Treesnake is a highly destructive reptile species that has extirpated many native species of birds, bats, and lizards from the U.S. Territory of Guam. For more than two decades branch scientists with the Invasive Reptile Project have developed, validated, and tested the feasibility of Brown Treesnake control and suppression at various spatial scales.
Developing Ecological Forecasting Models for Invasive Species
Forecasts of where species might be and what impacts they may have are necessary for management of invasive species. Researchers at FORT are using various approaches to provided needed information to resource managers to combat invasive plants, animals, and disease organisms.
Giant Constrictor Snakes in Florida: A Sizeable Research Challenge
Since the mid-1990s, several species of non-native, giant constrictor snakes, such as Burmese pythons and boa constrictors, have surfaced in localities throughout southern Florida. Several are known or suspected to be breeding and appear to be spreading northward. Increasingly, media and other reports of sightings or encounters with these animals have emphasized the dangers they could impose...
Invasive Species in the Everglades – An Opportunity to Engage Youth in Science
Invasive reptiles like the Burmese python (Python bivittatus) and Black-and-White Tegu Lizard (Tupinambis merianae) are exerting tremendous harm on Everglades ecosystems, but these problematic species present an excellent opportunity to engage the next generation in science. Since entering into an agreement with Everglades National Park in late 2013, the Invasive Species Science Branch of the...
Dataset: Forest growth in and around an ungulate enclosure on Northern Guam, 2005-2011
On an island largely devoid of native vertebrate seed dispersers, we monitored forest succession for seven years following ungulate exclusion from a 5-hectare area and adjacent plots with ungulates still present.
Argentine Black and White Tegu (Salvator merianae) can survive the winter under semi-natural conditions well beyond their current invasive range
The Argentine Black and White Tegu (Salvator merianae, formerly Tupinambis merianae) is a large lizard from South America. Now established and invasive in southern Florida, and it poses threats to populations of many native species. Models suggest much of the southern United States may contain suitable temperature regimes for this species,...
Goetz, Scott Michael; Steen, David A.; Miller, Melissa A.; Guyer, Craig; Kottwitz, Jack; Roberts, John F.; Blankenship, Emmett; Pearson, Phillip R.; Warner, Daniel A.; Reed, Robert Locally abundant, endangered Mariana swiftlets impact the abundance, behavior, and body condition of an invasive predator
Invasive predators are known to have negative consumptive and non-consumptive effects on native species, but few examples show how the abundance of native prey may influence an established invasive predator. We compared invasive brown treesnakes (Boiga irregularis; BTS) found in caves occupied by endangered Mariana swiftlets (Aerodramus bartschi)...
Klug, Page E.; Yackel Adams, Amy A.; Siers, Shane R.; Brindock, Kevin M; Mosher, Stephen M.; Mazurek, MJ; Pitt, William C.; Reed, Robert Understanding metrics of stress in the context of invasion history: The case of the brown treesnake (Boiga irregularis)
Invasive species can exert rapid depletion of resources after introduction and, in turn, affect their own population density. Additionally, management actions can have direct and indirect effects on demography. Physiological variables can predict demographic change but are often restricted to snapshots-in-time and delayed confirmation of changes...
Claunch, N; Moore, I.; Waye, H; Schoenle, L; Oakey, S; Reed, Robert; Romagosa, Christina Evidence for an established population of tegu lizards Salvator merianae in southeastern Georgia, USA
Documenting emergence of invasive species in new areas is vital to understanding spatiotemporal patterns of invasions, propagule pressure, and the risk of establishment. Salvator merianae (Argentine Giant Tegu) has established multiple unconnected populations in southern and Central Florida, and additional sightings have been reported elsewhere in...
Haro, Daniel; McBrayer, Lance; Jenson, John B; Gillis, James; Bonewell, Lea R.; Nafus, Melia Gail; Greiman, Stephen E.; Reed, Robert; Yackel Adams, Amy A. Highly competent native snake hosts extend the range of an introduced parasite beyond its invasive Burmese python host
Invasive Burmese pythons (Python bivittatus ) have introduced a nonnative pentastomid parasite (Raillietiella orientalis ) to southern Florida that has spilled over to infect native snakes. However, the extent of spillover, regarding prevalence and intensity, is unknown. We examined native snakes (n = 523) and invasive...
Miller, Melissa A.; Kinsella, John M.; Snow, Ray W.; Falk, Bryan G.; Reed, Robert; Goetz, Scott M.; Mazzotti, Frank J.; Guyer, Craig; Romagosa, Christina M. Behavior, size, and body condition predict susceptibility to management and reflect post-treatment frequency shifts in an invasive snake
Foraging behavior can have population-level effects that are of interest for wildlife management. For invasive species, foraging behavior has been tied to establishment ability and rate of spread and is generally of import in understanding invasion biology. A major method for controlling invasive vertebrates is using food-based baits as...
Nafus, Melia G.; Yackel Adams, Amy A.; Boback, S. M.; Siers, SR; Reed, Robert Landscape dominance of introduced herpetofauna on an oceanic island
Habitat loss and fragmentation can negatively impact native wildlife and facilitate establishment of introduced species. On islands, introduced species are a primary cause of extinction and can alter community membership through predation or competition for resources. Consequently, elucidating the distribution of introduced and native species can...
Hileman, Eric Thomas; Eichelberger, Bradley A.; Liske-Clark, Jill; Barnhart, Patrick D; Reed, Robert; Yackel Adams, Amy A.; Nafus, Melia G. Estimating detection probability for Burmese Pythons with few detections and zero recapture events
Detection has been a long-standing challenge to monitoring populations of cryptic herpetofauna, which often have detection probabilities that are closer to zero than one. Burmese Pythons (Python bivittatus =Python molurus bivittatus), a recent invader in the Greater Everglades Ecosystem of Florida, are cryptic snakes that have long periods of...
Nafus, Melia G.; Mazzotti, Frank J.; Reed, Robert Use of visual surveys and radiotelemetry reveals sources of detection bias for a cryptic snake at low densities
Transect surveys are frequently used to estimate distribution and abundance of species across a landscape, yet a proportion of individuals present will be missed because either they were out of view and unavailable for detection or they were available but not detected because the surveyors missed them. These situations lead to availability and...

Joseph Mitchell; Reed, Robert Genomic pedigree reconstruction identifies predictors of mating and reproductive success in an invasive vertebrate
The persistence of an invasive species is influenced by its reproductive ecology, and a successful control program must operate on this premise. However, the reproductive ecology of invasive species may be enigmatic due to factors that also limit their management, such as cryptic coloration and behavior. We explored the mating and reproductive...
Levine, Brenna A; Douglas, Marlis R; Yackel Adams, Amy A.; Lardner, Bjorn; Reed, Robert; Savidge, Julie A.; Douglas, Michael E Contact rates with nesting birds before and after invasive snake removal: Estimating the effects of trap-based control
Invasive predators are responsible for almost 60% of all vertebrate extinctions worldwide with the most vulnerable faunas occurring on islands. The brown treesnake (Boiga irregularis) is a notorious invasive predator that caused the extirpation or extinction of most native forest birds on Guam. The success of avian reintroduction efforts on...
