There is a lot on what happens when you put #biochar in the field, but what about back in the forest? Anyone have research papers to share? (Anecdotes also accepted.) 
YES! Found this: https://greenyourhead.typepad.com/files/biochar_for_forest_restoration_wba_rev.pdf from @kelpiew!
"Most biochar plant growth studies have been performed on field and horticultural crops, however, there are a growing number of studies on biochar and forest species. Many of these have been pot studies of forest tree seedlings. ..."
... A meta-analysis has summarized a number of these studies on responses of woody plants to biochar (Thomas & Gale 2015). The analysis found a significant tree growth response to biochar, with an average 41% increase in biomass." 
Gah, there is so much in this paper. Going to do a thread later.
