Often times the species quickly become pests and threaten local biodiversity. ]]> 2016-12-18 20:10:42 UTC https://padlet.com/17mateob/puiv6o20enpt/wish/144239928 Common Name: Brown Tree Snake Scientific Name: Boiga irregularisn (Merrem) 17mateob https://padlet.com/17mateob/puiv6o20enpt/wish/144240062

The brown tree snake is able to hide in small places and was most likely introduced in Guam by U.S military ships and/ or planes during WWII. The population of the invasive species has flourished on the island because of Guam's vulnerable prey, small size, and non-seasonal climate. The brown tree snake is also known to be an invasive species in Hawaii and the Northern Mariana Islands.

The color of the brown tree snake is dependent on its environment. The invasive species can reproduce eggs once or twice a year nearing twelve eggs beginning at age three. The fertilized eggs are left in protected, dark, and humid areas for nearly three months until the eggs are prepared to hatch. Once hatched, the young snakes must learn to fend for themselves. The snake is a little over a foot after being hatched and can grow up to three to seven feet by the time it has reached full adulthood.  Under captivity, the brown tree snake can live for up to thirteen years. The snake mainly consumes the colubrid snake. ]]> 2016-12-18 20:24:41 UTC https://padlet.com/17mateob/puiv6o20enpt/wish/144240748 Control of Species: Chemical 17mateob https://padlet.com/17mateob/puiv6o20enpt/wish/144241491 Scientists are hopeful that a deadly strain of paramyxovirus, currently under development, could reduce the snake population.  The virus would be spread through the snake population through inhalation. Another effective chemical is methyl bromide, but it could damage the ozone layer.

  • Barriers: Widely used method
    • Temporary: Nets and shade cloth
      • Less protection
      • Require more frequent inspection
      • Low cost
      • Easier transport and construction
    • Permanent: Masonry, metal mesh, vinyl 
      • Long-term solution
      • Vinyl
        • Protective
        • Durable
        • Better adapted for predator control
  • Trapping/ Inspection: 
    • Conducted by Wildlife Service and the U.S. Department of Agriculture and Plant Inspection Service
    • Nighttime searches and trappings are conducted mainly in cargo areas

The species is responsible for a decline in Guam's biodiversity. Since its invasion in the early 1950’s, the brown tree snake has caused the disappearance of nearly all of the native forest birds on the island of Guam. The insect population is expected to increase without the presence of avian insectivores, thus damaging the local agriculture. Lastly, the snake is responsible for the decline of the flying fox, a crucial species for the pollination and seed dispersal of tropical trees.  

    Economically, the brown tree snake is responsible for large-scale power outages and damages to equipment. The snake species  causes the power outages by crawling onto electrical lines or entering electrical transformers.
    Their damage extends toward the human population as well. The brown tree snake’s bite is not fatal, but can cause severe illness in young children.  Secondly, since the introduction of the brown tree snake, fruit bats have shown great declines. The bats are an important part of indigenous rituals on the island, so the decline in their population has encouraged bat harvesting in other areas of the Pacific. 

    Despite the many negative impacts of the invasive species, the brown tree snake has reduced the population of the island’s introduced lizards and shrubs.

More research is needed in order to control a further increase in the population of the species in Guam.   ]]> 2016-12-18 21:28:54 UTC https://padlet.com/17mateob/puiv6o20enpt/wish/144243920 Battling the brown tree snake in Guam 17mateob https://padlet.com/17mateob/puiv6o20enpt/wish/144244050 2016-12-18 21:32:17 UTC https://padlet.com/17mateob/puiv6o20enpt/wish/144244050 17mateob https://padlet.com/17mateob/puiv6o20enpt/wish/144724765 2016-12-23 02:13:00 UTC https://padlet.com/17mateob/puiv6o20enpt/wish/144724765 17mateob https://padlet.com/17mateob/puiv6o20enpt/wish/144724792
