2. What is vegetation biodiversity monitoring useful for?
Ecology of a forest
Quercus pubescens
Quercus robur
3. Conservation level of a forest
What is vegetation biodiversity monitoring useful for?
4. Survey model of vegetation
14 phytosociological surveys 20X20
m using Braun-Blanquet indexes
140 phytosociological surveys 2X2 m using
Londo indexes
5. Data processing
Distribution area (spettro corologico)
Raunkiaer life forms (spettro biologico)
Landolt ecological indexes
Cluster analysis (Syntax program)
Statistical estimation of species richness in 20X20 m and
2X2 m samples (EstimateS program)

Ecological indexes
F = soil moisture
R = soil acidity
N = soil nutrient
H = humus
D = texture and aeration
L = shade-tolerant
T = temperature
K = continental climate level
Landolt ecological indexes
19. Maybe these forest patches
are too small, and they are
affected by “edge effect”.
In 2X2 m plots, probably edge
species (alien, cosmopolites
etc) have been surveyed,
making all the plots more
homogeneous
