Task 2. Assess the change in sensitivity to fire of pilot areas through the years based on landscape structure, as reconstructed from the previous task, fire behavior models, sensitivity of fuel to weather and sets of fire weather conditions. Simulate future landscapes resulting from land use changes and fire occurrence.
Task 3. Fire conditions and landscape structure will be reconstructed from the area affected by the fire from a number of well documented fires (small to large) selected in vari-ous study areas. The relationship between area burned, fire conditions and landscape structure will be determined based on such conditions and landscape reconstruction.
Task 4. Large fires, which have
been burning during several days, will be selected in specific areas. The
course of the fire during the day and night (or during contrasted periods
for fire weather condi-tions) will be reconstructed. A comparison of the
areas affected during the most severe conditions and the less severe ones
will made.
Task 6. A number of large fires
will be selected in varied climate and soil environments, with patches
differing in their recent land use his-tory, and/or fire history, and/or
time of abandonment, with various seeder/resprouter ratios, etc. Species
composition and abundance (plants, animals) dy-namics after fire will be
measured in the various patches to determine convergence patterns.
Task 8. Measure spatial variability
of soil physico-chemical parameters and its dynamics with time after fire
in various types of patches across a watershed. Similarly, determine the
spatial pattern of vegetation recovery within patches across the watershed,
soil and plant water status.
Task 10. A number of fires of varied size and with a variety of patches differing in fire intensity will be selected along a climate/soil gradient. Species turnover in regard to prefire conditions (unburned control plots) will be determined.
Task 11. A number of fires of varied size and with a variety of patches will be selected along a cli-mate/soil gradient. The dy-namics of selected rare and endemic plant species will be measured in compari-son with more cosmopolitan species.
Task 12. Determine the fire ecology of rare/endemic plant species in relation to more cosmopolitan species: sensitivity to fire and/or dispersal capacity and/or sensitivity to postfire environments.
Task 13. Modeling species dynamics
in relation to landscape structure and other characteristics of the fire
regime.
