this is in my neices backyard. ive been admiring it since they bought the house 4 years ago. actually been thinking,"i sure would like to see the lumber thats in it." but then again, i want to see it live a longer life. anyways, i was out checkin the yard this morning and looked up to see this at the 1st crotch: i havent noticed that spot before. im not much of a tree guy but it somewhat looks like a lighning strike. idk if its going to hurt the tree or not,if it could cause problems later on, or if the tree will be ok as is. the tree is 32 DBH and sure would like to see it there for many years. but then again, i also want to see the lumber!!! any help is GREATLY appreciated.
