There are several ways selection can affect population variation:
stabilizing selection
directional selection
diversifying selection
frequency-dependent selection
sexual selection
As natural selection influences the allele frequencies in a population, individuals can either become more or less genetically similar and the phenotypes displayed can become more similar or more disparate. In the end, natural selection cannot produce perfect organisms from scratch, it can only generate populations that are better adapted to survive and successfully reproduce in their environments through the aforementioned selections.

Answer:
Well, on one hand, this is a good thing as negative effects of the high demand for wood such as deforestation can be minimised. This will also sustain the supply of wood for several applications. However, there could be negative consequences of propagating such genetically-modified trees, which were not stated or are not yet known. For instance, the trees could be extreme soil nutrient consumers—depleting soil nutrients at a faster rate than they can be replenished and rendering such soil infertile in a short period.
