Using inventory variables for practical biodiversity assessment in plantation stands

Aim of study: Practically and simply assessing biodiversity by using inventory variables in four types forest plantation stands (mixed pure) including species such are chestnut, blue gum maritime pine.
 Area Northwest Portugal Vale do Sousa (14,840 ha), which is 97% covered with forests.
 Material methods: Simulated data, from 90-year stand-level management planning, were considered three indicators: tree (number different origin—native or exotic), mean diameter at breast height (DBH), shrub biomass. Two regeneration (fully regenerated seed fully resprouting), site quality conditions also considered.
 Main results: Mean scores varied between very low (10.13) pure on lowest-quality sites seed, (29.85) mixed a dominance pine, best-quality resprouting. Site type significantly affected all dominated pine chestnut stands, while less gum.
 Research highlights: The indicators cover the major aspects allow assessment over time. findings relevant for conservation fire protection management.
