Aradia requested that I post this here. I was thinking about an "Appleseed" badge that would reward a player for planting some number of the _least_ represented trees in the game. Wood trees tend to die (I think because 1) they're not as attractive as the other trees and 2) if I understand correctly they're the only tree you can kill without tree poison,) so a badge that ensured that people were constantly replenishing the stock of wood trees would be really helpful.
