How to develop forest reserved land?

Look at the pictures of the land acquired by PR Selangor state government from Talam Corporation. It is really a peaceful and forest reserved area. How to develop such beautiful land? Why PR government buys these land that cannot be developed?

Talking about green environment some more. PR government really knows how to twist things to their own benefit. On one hand, PR government supports anti Lynas, on another hand, they want to develop forest reserved land and construct buildings.

The question is why PR Selangor government buys such land from Talam Corporation?
