One landscape many views but not necessarily so

I found this notice beside a lovely lake. Why is planting trees always seen as "the answer" to any problem, which in this case is erosion and lack of bio-diversity.

The newly fenced area has no room for any more trees as the ground is already severely shaded by the existing ones, which themselves are causing the erosion they are so concerned about.

Planting seems perverse when the answer is to remove some of the existing conifers. Biodiversity, plus the broadleaves at the pond edge, would then have a chance.
