Grow the Forest is still one of the top two Focus votes even though no one is voting for it as an action. I'm not sure why it's so popular, honestly. Even with the 25% bonus, we'd need 31.68 successes to reach the next Magnitude. That's not likely to occur any time soon.
We're currently at 4 out of 20 Special Trees - 2 Shield Trees, 1 Collector Tree, and 1 Clever Tree. We're almost certain to get 1 Wise Tree next update so what other Special Trees do we want to aim for this Fall before the 50% Growth malus hits in the Winter? It looks like growing Special Trees usually gets 10-15 dice from Action votes per Turn so that's an average of 5-7.5 successes each update, which would be 20-30 successes for the 4 updates of Fall. We do have a 25% bonus for growing Special Trees up to 12 Special Trees, and Focus votes can add 3 successes each so that's possibly 25-45 successes, depending how many Focus votes growing Special Trees get.
I think I'd like to aim for 1 more Clever Tree, 1 more Shield Tree, and possibly a second Wise Tree. I think we're going to be doing a lot of research in the Winter to take advantage of the additional die from the Wise Tree while Growth is disadvantaged. Also, researching the Lens Tree seems unpopular, and having a Clever Tree boosts whatever successes we have for that action. The GM has said that we'll face an enemy before the year is out so another Shield Tree sounds like a good idea. Towards the end of Winter/beginning of Spring, I'll want to grow more Collector Trees and hopefully a Lens Tree, but I don't know if they'll provide very much of a boost before Winter hits if we get them now.
