I've been depending on ponds/wells during this event instead of trees.My trees aren't dropping Living Wood, but my Sawmills are, so I have a wood supply from there. Other Living Wood droppers I am collecting from also occasionally drop wood too, so that's another source. I am working my way towards 2 dozen ponds as I slowly expand, I'm around 17-20 ponds now. I have about half dozen wells, probably build up a dozen in time.
My tree strategy is to buy 30 at a time. I tap on units of 10 when growing. If a weekly Ali is available, I can hit the entire group and have a few energy left for an event related item. If I am concentrating on, say, ponds, and I have 17-23 energy left after login, I can do a row of 10, collect from resource buildings & workshops, etc. My dailies let me do perhaps another row or 2 of trees. Dead trees also supply wood, I work on those if I have enough planks from the ponds/wells.
I also stock up on trees ahead of WW to make at least 1 pass then. I try to keep 30 or so around, this event has depleted them.
