Okay, so you do this because for certain tree species, like the Freeman Maple, you haven’t added to the benefits calculator yet. I’ve made it so that all the trees are now included in the list but the benefits are only calculated for certain species, such as the Sugar Maple.
For my purposes, it seems better to have people adding the correct species, but not have the benefits calculated, rather than the incorrect species (with benefits).
Perhaps I can look through the literature and update the species list for which benefits are calculated.
Cheers,
