Introduced Alien Species in the Philippines
A mean, fast growing and invasive tree species introduced to the Philippines because it can out-compete many local trees for space and sunlight.
Gmelina Arborea
What is the host of Gmelina Arborea?
Azola minor, Attacus and Xyleutis spp
It is succesful at invading natural forests due to the following attributes of the species. It makes the soil its planted on acidic. (Mahogany)
Switenia Macrophylla
Also known as the giant neotropical toad or marine toad. (Cane Toad)
Rhinella Marina
Originally introduced for aquaculture, but this snail (Golden Applesnail) has become a pest in rice paddies, damaging crops and affecting local rice production. It's common on wetlands, rice fields and other freshwater environments.
Pomacea Canaliculata
Displaced most invertebrate faunas; pest to agriculture as it harbours phytophagous insects that reduce crop productivity. (Big headed ant)
Pheidole Megacephalus
Tilapia was introduced for fish farming, but it has escaped into natural water systems where it competes with indigenous fish for resources, sometimes leading to declines in local fish populations.
Oreochromis Niloticus
Affected vegetables and ornamentals. Accidentally introduced with the importation of ornamental kalanchoe in the 1970s. (Spiraling Whitefly)
Aleurodicus Dispeures
This non-native toad species competes with local ampjibians for food and habitat and can spread diseases to which natibe amphibians have no immunity. (Black-Spotted Toad)
Duttaphrynus Melanostictus
This invasive species grows rapidly, and often forms dense scrambling thickets overgrowing natural vegetation and subsitence and commercial crops, grazing lands, and silviculture.
Chromolaena Odorata
Water Hyacinth can completely cover lakes and wetlands, outcompeting native awuatic species, reducing oxygen levels for fish and creating ideal habitat for disease-carrying mosquitoes.
Eichhornia Crassipes
It can climb trees or shrubs suffocating them and outcompeting understorey plants.
Bougainvillea Spectabilis
This thornless tree can form dense monospecific thickets and is difficult to eradicate once established. (Giant Ipil-Ipil)
Leucaena Leucocephala
Invades pinelands, hammocks and scrub habitats. Can shade out rare plants and displace native flora.
Acacia Auriculiformis
It smothers and kills indigenous flora. Sharp and recurved thorns of the weed can make animals reluctant to graze on it and difficult for them to penetrate the thickets.
Mimosa Invisa
