Are there lots of snakes in guam3/22/2023 ![]() ![]() The study is funded by the Budweiser Conservation Scholarship and the National Science Foundation's (NSF) Integrative Graduate Education and Research Traineeship (IGERT) and Graduate Research Fellowship programs. This spring, I-along with my co-advisers, Joshua Tewksbury and Janneke Hille Ris Lambers, our collaborator at the University of Guam, Ross Miller, and my field assistant, Theresa Feeley-Summer-began to examine whether the loss of birds had caused changes in how the seeds the birds typically eat are distributed. ![]() program in biology at the University of Washington to investigate how bird loss changes the movement of seeds around Guam's forests. Yet, three weeks later, I was on a plane headed there.Īs I worked on Guam during the next three years, I often wondered why no one was studying how Guam's bird losses impacted the forests' remaining organisms. Although I had heard the snake story in my college conservation biology course, I did not know where Guam was when I applied for the job. Geological Survey to develop a "Rapid Response Team" that would identify and eradicate new populations of brown tree snakes on U.S.-associated Pacific Islands. I started to think about the potential ecological impacts of bird loss in 2002, when, two years out of college, I was hired by the U.S. Guam's now silent forests currently hold about 13,000 snakes per square mile. As a result, 10 of the island's 12 forest bird species are now extinct on Guam, and the two surviving forest bird species remain only in tiny, localized populations where snakes are controlled. This snake became Guam's new top predator and ate its way through a buffet of the island's bird community. How did Guam lose its birds? In the mid-1940s, the brown tree snake was accidentally introduced to what was then snake-free Guam. For more information, see What Are Injurious Wildlife: A Summary of the Injurious Provisions of the Lacey Act and Summary of Species Currently Listed as Injurious Wildlife.Can forests that have lost all of their birds still function normally? This is an important question for the now bird-less forests on the island of Guam, an island in the western Pacific. Plants and organisms other than those stated above cannot be listed as injurious wildlife. Injurious wildlife are wild mammals, wild birds, amphibians, reptiles, fishes, crustaceans, mollusks and their offspring or eggs that are injurious to the interests of human beings, agriculture, horticulture, forestry, wildlife or wildlife resources of the U.S. Preventing the introduction of new harmful species is the only way to fully avoid impacts of injurious species on local, regional, and national economies and infrastructure, and on the natural resources of the U.S. An injurious wildlife listing would not prohibit intrastate transport or possession of that species within a State where those activities are not prohibited by the State. or transport between the listed jurisdictions in the shipment clause (the continental U.S., the District of Columbia, Hawaii, the Commonwealth of Puerto Rico, and any possession of the U.S.) without a permit. ![]() Includes species listed as injurious wildlife under the Federal Lacey Act ( 18 USC 42), which makes it illegal to import injurious wildlife into the U.S. For more information about OIA funds provided to counter invasive species visit. ![]() Department of Agriculture (USDA), and the Department of the Interior. The Brown Tree Snake Control program FY 2021 funding was divided among several governments and federal partners to include Guam, the Commonwealth of the Northern Mariana Islands (CNMI), Hawai'i, U.S. "Each year, OIA provides significant funds to critical efforts seeking to help restore balance." "Islands are particularly vulnerable to invasive species that disrupt natural, long-standing biological processes and threaten our unique, island eco-systems," said Deputy Assistant Secretary Keone Nakoa. An additional amount of $1,791,421 from Coral Reef and Natural Resources FY 2021 funds was also announced earlier this year for the purpose of controlling and mitigating other invasive species in the Insular Areas besides the brown tree snake. Department of the Interior's Office of Insular Affairs (OIA) has announced $4,095,922 million in Brown Tree Snake Control program fiscal year (FY) 2021 funding as administered through the Technical Assistance Program. ![]()
