Cut down a few trees and let the sun do the work. The natural growth in the opening will increase ten fold with all the sunlight and the regrowth from the stump, especially maples, will get hammered by deer. And FYI, Japanese Honeysuckle may produce alot of fruit for songbirds and deer, but in a matter of a few years, it will completely chock out the understory and lessen your natural vegetation/feed.
