how do you make trees grow?

Hi guys. Remember that orc level right after you harvested the 15k lumber as grom...in the opening cinematic Cenarius the demigod shows up and causes all the trees that you cut down to grow back up into trees. I want to do something similar in my map that I'm creating...when the heroes enter a certain area a druid in the area causes a wall of trees to grow up from stumps forcing the heroes to find another way in. The only thing is...I have no clue how to do this.

my thoughts...it might have to do with the animation triggers...

anyways, thank in advance you experts out there.

I think you could just place some dead tree walls, place a region over them, then when the hero enters the region, do action:

Destructible Doodad - Pick Every DD In Region (= region over the dead tree walls) And Do [Action]

Action = Resurrect picked DD with max life of (i just select a tree that`ll never be chopped, it works so don`t want to go trying anything else if it works anyway) and show birth animation.

That should work.

thanks a lot that worked great!
