before the human influences,Maybe… Deers had browsed the sprouts of branchesAnd maintained the maquis open

In the past,

But now, after generations of cutting and burning,There are closes maquis, with multy-stem Quercus calliprinos, and climbers

We made a survey in Meron forest in purpose of learning and planning

Schematic stem thinning in Q. calliprinos maquisA. Original position of multi-stem adults, and young trees

B. After stem thinning inside the maquis. leaving of 2-3 stems in each mother-tree

C. After stem thinning inside fuel-brake. leaving of one stems in each mother-tree

With pruning of side branches up to 2.5 m

2-3 m between the branches

5 m between stems of the adult.

The sustainable managementThe cattle grazing is part of the project planning

Sprouts are growing after the stem cutting

The cattle with goats browse the sprouts and prevent the closing the maquis again
