More Trigger Help Needed

What is the trigger that makes trees grow back, also i need to know the trigger to set my camera farther back cause my map is big and ingame you command armies so i want a farther view so players can see where they are goin and what not.

make a new trigger x (names dont matter)

Events
(none)
Conditions
(none)
Actions
Wait (tree regrowth time)
Revive Dying Destructable at blah blah blah

new trigger y

Events
Elapsed Game Time is .01 seconds
Conditions
(none)
Actions
Pick every destructable in playable map area (matching x) and do actions
Add an event to trigger x which is Destructable - (Picked Destructable) Dies

I'm writing this from memory, so I may have a few names, etc wrong.
Also, I'm pretty sure the GUI way of enuming destructables can pick up any number, but it may only pick up 64, same as the event.
