[Pokemon] Are there any laws that limit the collection of rare Pokemon from the wild?

Similar to laws protecting endangered species?

There are a few rules here and there, but the prevailing attitude throughout the Pokémon universe is if you can do it, we won't stop you, but you try at your own risk. 

Some people won't let you enter locations rare Pokémon are known to live unless you have proved your ability to master a certain number of gyms, learned the appropriate HMs, own the right Pokémon, and all these obstacles prevent too many people from obtaining the rare Pokémon. 

But because the rare Pokémon in the wild are strong, because they're hard to find, and because trainers are more likely to get killed by those Pokémon than the Pokémon getting over-trapped, there tends to be little need for protective laws.
