It has long been known that Meganium possess the ability to make many plants grow at twice their normal speed. This ability, as many farmers have bemoaned, does not work on grains, vegetables, and other plants domesticated for human consumption. Yet when they are planted in a recently clear-cut forest, or even an abandoned town, they become a powerful demonstration of the healing powers of the environment; no wonder that they have been worshiped for so long as gods of nature!

But unlike gods, Meganium are all too mortal. Even before the Bayleef trade their numbers had been in decline from habitat destruction, and when the former piety of the Orange Islands was replaced by an anti-colonial rage, they were not spared. As time passed and forests were sacrificed to the gods of world trade and industry, it came to be believed that the Orange Islands were being punished by the Meganium for the sin of habitat destruction, and their worship has now become more common than it was in the age when there seemed to be one or two of these pokemon in every forest.

In recent years, efforts have been undertaken to reintroduce Meganium by importing Bayleef from Johto. These efforts have divided the community, with some viewing it as atonement and others as sacrilege, but all the Orange Islands hope it will lead to the forests' welcome return.
