on your insights page it states that trees weaken the land. I wonder how this could be so, when in fact we know that trees help the land to stay solid and help to avoid runoff and mud- (I live in Southern California where we have mud-slides).

It is all a matter of context. When the Gemara and Rashbam here say that trees "weaken the land" around them, they are referring to vegetable farming. Trees can have a bad effect on vegetables planted in their immediate vicinity (by blocking light etc.). That is the only way trees adversely affect the land around them in our Gemara.
