no
Any plant can pollinate with any plant. Just so long as there's bees there. Bees accidentally get pollen from other plants on there feet and can ACCIDENTALLY cross-pollinate. So, yes, a pear CAN pollinate with a plum tree.
According to my planting guide it says the tree is self pollinating. My tree has produced fruit for more than 7 years but if I can't find out how to prevent the squirrels from eating the immature fruit it will come down. My latest device is a motion activated sprinkler and this seems to be working. The tree is loaded. (Note there are no fruit trees near this tree to pollinate it).
No, pear trees and apple trees cannot cross-pollinate successfully because they belong to different genera (Malus and Pyrus). To ensure proper pollination for fruit production, it is best to plant two apple trees or two pear trees of compatible varieties in close proximity.
Parker or Patten will pollinate a Summer Crisp.

The fruit of the callery pear tree ( Pyrus calleryana) is called a pear.
I believe that Bartlett Pears can self polinate. As in one tree. If you have 2 trees, well, the more the merrier, but a polinator is not needed.
