How does woodland increase biodiversity?

Biodiversity. A number of studies have shown that in the UK managed woodlands increase in biodiversity value. Woodlands are not static entities that can be left without interference, they are changing environments and as trees grow larger; the nature of the habitat will change.

What is the importance of biodiversity of trees in supporting a healthy ecosystem?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
