QGIS Atlas zoom to intersection between two different layers

I have two polygon layers, one is about different land owners boundaries and is used for atlas generation, and the other is about forests inside each property. In atlas generation sometimes i want to zoom to the intersection area between the boundary layer (used for atlas iteration) with the forest layer. That is because some times a huge property can have a small part of forest so i want atlas to zoom in to that part of the property. I was thinking to type a function in the scale bar, maybe $atlasgeometry, geometry, intersection, etc. Can anyone help with this issue?

I am using QGIS 2.8.1 Wien.
