Evil Tree Bothers My Town Planner

[1234567]

I am going to build a mine in my town but a tree on the hill makes my dream go far away [img]<fileStore.core_Emoticons>/emoticons/sad.png[/img]/emoticons/sad@2x.png 2x" title=":(" width="20" />

What can I do to eliminate the evil tree without flatting the terrain? 

(The tree cannot be cut by villagers, it comes with the map)
