How much wooden content can a wood modification modify if said modification could actually modify wood content??

Scientists remain perplexed.

But I have the answer! It's precisely twelve completely new tree species that integrate naturally into world generation and provide full wood sets to fill gaps in the existing wood color spectrum. From bright knotty pine in taiga forests to rich mahogany in jungles, from warm orange cedar in wooded badlands to deep black ebony found sporadically in sparse jungles - there's a wood type here for every preference.

Pairs nicely with other vegetation-adding modifications.
