What type of tree is this and its life expectancy?
This tree is around 35' Tall and is in the courtyard of one of our schools. The school is being renovated and they have chosen to keep the tree and put gutter leaf guards on the school. It provides great shade and is beautiful, but I am concerned of the life span of this tree and its current size. Could you please give me your thoughts on keeping this tree, Type and an expected life span from its current size? Thank you.

This looks like a type of Callery pear. The usual variety you hear about is the 'Bradford' pear. Unfortunately, this Asian pear was known to be highly invasive crowding out native plants in parks, large areas, etc. The "berries" are actually "pears", that germinate at a high rate. Branch crotch angles are prone to splitting and breakage. Alternative cultivars are less prone to this. Take a look at the link on the Callery pear from the MD Invasive Species Council http://www.mdinvasivesp.org/archived_invaders/archived_invaders_2007_04.html
In general the life span is about 25-30 years old. All this depends upon site conditions, environment, etc. At this point, you should contact several certified arborists regarding the health of the tree and the best way to proceed. http://www.treesaregood.org/
