Study
What we can do
・We must learn the knowledge for the naturalized species.Web must learn problems and the kinds of the naturalized species.
・We must prevent from leaving the naturalized species to a river and the sea not to annihilate the local native species. When we miss them, species of the strong propagative power spread, and the native species may become extinct.
・When we keep necessary specific foreign creatures, we apply for permission and keep them in specific breeding facilities.
When we leave specific foreign species and keep them without permission, you are assigned to penal servitude or a fine.
（The example of the specific foreign creatures: Mammals: nutria, raccoon and so on,
Reptiles: Snapping turtle,and so on. Amphibians: bullfrog,and so on. Fish: bluegill,and so on.
Crustacea: Uchida crawfish,and so on. Plants: water cabbage, parrot feather,and so on.）
The naturalized species are found recently in each place. The naturalized species such as alligator gar and the loggerhead may exterminate the native species. We must prevent from leaving the naturalized species to a river and the sea not to annihilate the local native species. The killifish may become extinct by a guppy. We must keep them without leaving them.
What we want to do
・We want to plant trees producing fruits and install the birdhouse and observe the bird.The trees where birds come to eat fruits: artubus, persimmon, nandin, blueberry
The trees where birds come to eat nuts: cherry trees, camellia, magnolia, sasanqua
・The biotope where many kinds of dragonflies come over.
Dragonflies live in the places where rice plants are low, and damp ground.
・The biotope where fireflies come over.
The livable environment of Heike fireflies are rice field, damp ground without the flow with pure water. The livable environment of Genji fireflies are rivers with the flows with pure water. Their baits are conches such as marsh snails, mud snails.
