|Abstract: ||In order to discuss new management strategies and point out whose silvicultural actions ensure macrofungal
communities sustainability in montado ecosystems, studies have been developed on how macrofungal richness and
fruitbody production varies in relation to several vegetation factors (canopy cover, proximity of crown projection
area, shrub cover and herbaceous cover).
The sporocarp surveys were conducted in representative sites of the most common (cork and holm oak) open
montado ecosystems in Southern Portugal.
Results showed that canopy cover strongly shaped macrofungal communities composition and yield. Denser canopy
cover enhanced mycorrhizal richness and reduced saprotrophic yield. Furthermore, mycorrhizal richness and yield
increased with tree proximity. On other hand, mycorrhizal richness increases with tree age class and shrub cover,
while saprotrophic richness increases with shrub cover and herbaceous cover.
Results seem to emphasize the importance of tree and shrub vegetation layers for macrofungal community’s
maintenance in montado ecosystems. Therefore, we recommend canopy cover values to be kept around 40-50 %
and propose that strips and patches of natural shrubby vegetation should be retained in order to enhance
macrofungal richness and yield in montado ecosystems.|
