Situation: Introduction of non-native species
Species: Brown tree snake in Guam
Impact on ecosystem: The introduction of the non-native species, the brown tree snake, in Guam has had a severe impact on the ecosystem. The snake is a predator that has decimated the bird population on the island, leading to the extinction of several bird species. This disruption in the food chain has caused a cascade effect, affecting other species that relied on the birds for food or as part of their habitat. The loss of birds has also led to an increase in insect populations, further disrupting the ecosystem. Overall, the introduction of the brown tree snake has had a significant negative impact on the biodiversity and stability of Guam's ecosystem.
