The new tree anarchy behavior is to keep the freedom of placing trees and at the same time provide the ability to delete the trees when placing roads and buildings.

To turn on tree anarchy, the current key binding is ALT + A. You may re-assign it to your preferred key binding. You may also click on the "tree anarchy" icon located in the indicator panel usually located between the demand panel and temperature panel.

The current default behavior is to unhide the trees which has been hidden by roads and buildings. This is to cope with avid detailers, who also use my Prop Anarchy + EML mod, to prevent props being hidden as well.

If you don't use Prop Anarchy + EML, and you're not into detailing and just play this game for its gameplay, I've included an option in the option panel to "Hide tree on load", which you can enable if you want to keep trees hidden.

In the case that you want to unhide trees, there are a couple ways to delete these trees easily without going through the map and deleting them one by one.
Solution one - This is the easiest

• Go to Tree Anarchy option panel, and select "Delete tree" on overlap
  
• Turn off tree anarchy either pressing ALT+A or clicking the anarchy on indicator panel
  
• Then use move it and slightly nudge the road or building and the trees will be deleted. You may use MoveIt undo to move the road or building back to its original position. You may also select all the roads and buildings using MoveIt marquee selector.

Solution two

• Go to Tree Anarchy option panel and select " Delete tree" on overlap
  
• Turn off tree anarchy either pressing ALT+A or clicking the anarchy on indicator panel
  
• Then use the road tool and upgrade the roads, or place new buildings and the trees in the area will be deleted.
