There are a number of points and questions there. I'll maybe start with the last one and then pass off to Ms. MacDonald.
You're quite right. A lot of the analysis was about whether this tree was a viable candidate for relocation and replanting, but we did look at what would be required if the tree were to stay in situ; if the visitor welcome centre were going to be quite significantly altered in its scope, what would have to be done? It seemed to be, one, fairly significant, and, two, with a low likelihood of success.
Maybe I'll pass it on to Ms. MacDonald to give some expert testimony.
