A group G is called subgroup conjugacy separable (abbreviated as SCS), if any
two finitely generated and non-conjugate subgroups of G remain non-conjugate in
some finite quotient of G. We prove that the free groups and the fundamental
groups of finite trees of finite groups with some normalizer condition are SCS.
We also introduce the subgroup into-conjugacy separability property and prove
that the above groups have this property too.
