investment, with a tree like this, the other challenge that we have, is that, there are fruited, fruiting varieties, planted in san francisco and as you can all see, there's fruit on this tree. and, the problem with that is that the fruit, will drop and it can actually, become a pedestrian hazard. it is kind of hard and can smash in the sidewalk and become slippery and the fruits themselves are rolling. we generally don't encourage fruiting trees in the right of way. there are nonfruiting trees, we ask people to consider that, if they're interested in this tree. >> we have all sorts of stuff happening here. and none of it good. >> does anyone know about this? >> yes it is, that's an olive, for whoever doesn't have a mike. >> if you look across the street, you can see what this tree probably used to look like. unfortunately, this is an example of what i described earlier, where you top the tree, you cut the top off it. a lot of times, when people see a tree there is really overpruned and you see new growth, and you see the tree is coming back, it is recovering. but actually, this is a sign of stress
