Are ther any types of trees that can be planted among english IVY?

Nearly the entire back of my yard is covered with IVY. It was pre-existing whe I bought my house. The Ivy is also in my neighbors yard, if I mow it, it will creep back from their yard. I know Ivy can be harmful to trees. I have 7 or 8 trees already growing in the Ivy. Mostly Oak %26amp; Maples w/ one Pine- but they seem to be somewhat affected by the Ivy's growth.. I cut the Ivy off them yearly, but it climbs fairly fast. I'm looknig for tree's or shrubs that will no be severly affected growing in Ivy. What can I do with that area? I was thinking maybe Holly?

Basically, any tree or shrub can grow in the ivy, but with any type there are basically two problems you can't get away from . One you already know and you're doing the right thing about it, keeping the ivy from climbing up and choking them (but I would do it more often). What is also happening is the ivy is competing for water and nutrients the other trees need to be strong and healthy. With shrubs it can be more difficult to maintain the ivy than around trees, but in either case it's good to maintain a distance of 18-24" away from them to give them their space and you won't have to be cutting it back every day.
