The vegetation
in Gargano, especially in Bosco Quarto and Foresta Umbra comprises also
vegetation released from long-term anthropopressure, which appears mainly in
abandoned, scattered settlements and numerous old fields at the bottom of
carstic dolines. Forest and grassland vegetation in Bosco Quarto and Foresta
Umbra is marked by the effects of long-term anthropopressure variable in form,
persistence and intensity.
The geobotanical relations and
ecological phenomena prevailing here were considered convenient for veryfing
our earlier geobotanical-cartographic concepts. This research resulted in two
maps of the vegetation and of the dynamic tendencies in it and two derived maps
supplemented by a common theoretical-methodical text and the necessary
documentation.
The map of Gargano describes the
dynamic state of the vegetation within a given time by notions that determine
the dominance of fundamental ecological processes: fluctuation, primary and
secondary succession, regression, degeneration and regeneration (Falinski,
Pedrotti 1990, 1993 and new maps).
