It very well could affect some of them. Black Walnut roots seep juglone
into the soil, and while it's best known for being very toxic to
tomatoes and white birch, there are many other plants, trees and shrubs
it affects. Try a Google search on "plants affected by black walnut" as
an example. I believe the Wiki article on Black Walnut also gives a
list, though it is probably not exhaustive.
