Transcript of Wanted Poster- Brown Tree Snake

Brown Tree Snake Wanted! Victims The Brown Tree Snake has caused or been a major factor in the extinction of most of Guam’s native terrestrial vertebrates, including fruit bats, lizards, and almost all of the island’s forest birds. Also, brown tree snakes in Guam have damaged agriculture by preying on poultry, killed many pets, and bitten many children (The Brown Tree Snake Control). Measures Taken to Apprehend the Criminal Crimes Committed In its native range, the snake's populations are kept in check through natural processes such as disease, competition for food, and predation. Although these processes likely occur on Guam, they are not adequate enough to control the brown tree snake population ("Brown Tree Snake Alias: Boiga Irregularis.")
In order to contain this threat, the Brown Tree Snake Control Comittee was established in 1993 (The Brown Tree Snake Control). Their plan to manage to issue is as follows:
• reduce existing brown tree snake populations over large geographic areas on Guam;
• prevent the spread of brown tree snakes to other Pacific islands and mainland areas;
• eradicate or contain new populations as soon as detected;
• develop more effective and environmentally sound control and/or eradication strategies
and methods;
• protect endangered species and other wildlife from brown tree snake predation
(The Brown Tree Snake Control). Preferred mode of travel The Brown Tree Snake is a highly successful colonizer, able to sustain large populations even in close contact with humans. On small islands such as Guam, the population quickly grows to cover almost every area. These snakes then hide in crates and boxes filled with merchandise or cargo bound for other islands or the continental United States, where the snake can continue to colonize (The Bronw Tree Snake Control). How it made it to the scene of the crime The Brown Tree Snake was accidentally brought to Guam, an island that naturally had no snake species, aboard a post- WWII cargo ship traveling from the South Pacific region (Fritts). This sort of unintentional introduction is unfortunate. When an invasive species goes undetected for some time, allowing it to establish a strong population and to negatively affect the existing populations (Invasive). This species of snake is wanted for invading Guam and causing severe ecological and economic damage. It will eat almost anything and is responsible for the almost complete loss of many native bird and lizard species (Invasive). In the absence of these, it will also eat rats, mice, domestic birds and their eggs (Brown). This reptile has caused many power outages by climbing on the electrical wires (Invasive). Sightings Alias- "Boiga irregularis" Works Cited (Brown Tree Snake: Boiga Irregularis.) The Brown Tree Snake has been sighted in Guam and Hawaii as well as New South Whales, Australia, Papua New Guinea, Spain Taiwan, Texas, and several smaller Hawaiian islands (Brown Tree Snake Alias).
