logging and wood harvesting are threats to the vegetation diversity of the savannas
and heathlands in several parts of the world (Figs. 6 and 7).
Natural system modifications such as fire and fire suppression and the invasion of
native and alien species are non-negligible threats to species living in heath, shrubland and savanna habitats (Figs. 6 and 7).
Fires are an important factor. Depending on the regional frequency and seasonality of natural fires, the effect can be stabilisation of or damage to the natural species
