As forest areas shrink and become fragmented, many tree species face problems. They often rely on animals that can no longer disperse their seeds effectively.
Biodiversity loss is the biggest environmental problem we face today, according to a UN report that came out last year. One of the main reasons is that large forest areas are disappearing due to human impact.
A lack of connected forests can prevent trees from multiplying efficiently. The more fragmented the forest becomes, the greater the problem for the trees.
“Forest fragmentation has a negative effect on seed dispersal by means of animals,” says Emma-Liina Marjakangas at the Centre for Biodiversity Dynamics (CBD) in NTNU’s Department of Biology.
