Wild Tropical Vines

The woody vines started from the ground, circled around the tress and finally covered most of the trees. The forest appeared dark.  
I cut at the ground level all these vines, stopping the water and food supplies to the top.
It took six months before the entangled vines finally fell down on the floor, bring sunshine into the forest again. 
It is a long battle between an amateur farmer and the forest.
