Abstract:
In 1989 a wildfire destroyed 300 ha of natural pine forest and Mediterranean woodland on Mt. Carmel, Israel. Consequently an interdisciplinary scientific effort in fire ecology was initiated in order to propose recommendations to the management authorities. Field data gathered on soil erosion in the Mt. Carmel site implied that erosion is severe only during the first winter after fire, but it does not seem to present a significant threat to longterm ecosystem recovery. The recovery of the natural vegetation mitigates erosion, and there is no special need for any precautions to be taken immediatly following fire. Salvage cutting of burned trees had no effect on pine seedling recruitment, on vegetation development and on plant species diversity. Salvage cutting did affect passerine bird community by slowing down succession rate. For successful regeneration of the pine forest the burned site need not to be planted, since the number of natural pine seedlings is safficiently great, and there is a need to conserve the genetic and spatial variability of the forest. Although thinning has a positive effect on short-term pine survival and growth, such action is not recommended since pine seedlings are susceptible to pine bast scale (Matsococcus josephi) up to seven years, and to severe damage by porcupines. Selection caused by this bast scale might improve the resistance of the new pine forest stand. Pine seedling growing in the microsites of the old burned pine trees should be treated carefully, since some of them, due to their fast development, appear to be the next generation of the forest. Thinning of these groups can be considered after seven years, accompanied by removal of Cistus dwarf shrubs. However, where porcupine damage is observed, thinning should be done at low rates and with no pruning of side twigs. Since animal succession is a consequence of the change and progress in vegetation structure, there is no need for animal resettlement. The concept of "fuel breaks", combining a single massive thinning of the woody vegetation and an annual short but heavy grazing, is a management option for decreasing fire danger and future fire damage.
