My brother and i started a map some hours ago, we created a huge tree fortress, and some complicated redstone wiring systems to make the house looks cool and such, but when we where starting to put the leaves and vines we didn't liked the color, and the appearance, i know that this is my fault, but, there's something to do to change the biomes or copy it to another world?
use MCedit to copy move it to another place or copy to a new world, sadly it isnt possible to change biomes, there was a plugin for multiplayer a long time ago but its very out of date.
