It depends on how you classify "good for the environment." In terms of biodiversity, if tree farms are replacing old-growth forests, they're terrible for the environment. However, if tree farms are located in places that have long been cleared (such as conventional farm land), they can bring back biodiversity, prevent soil erosion, and most importantly are extremely efficient at carbon capture. Of course, most of the studies on this are sponsored by the paper industry, and it's really difficult to get unbiased information on the subject.
