Spatial Join - Polygons to Polygons

Hi Community,

I have 20.000 Assessment units 5x5km (Polygons) and a habitat map with 18 classes in different size and shape (see screenshot). Now I need to know the number and the kind of habitats within each assessment unit.

I did split the habitat map into single shapefiles by attribute and performed a spatial join (one to one) 18 times with the intersects option. However, smaller habitats that are within my target feature or bigger habitats that contain my target feature are ignored. Only the habitats that intersect with the boundary of my assessment units are used.

Whats the easiest and quickest way to sort this problem out?
Your help is really appreciated.
Thanks!
Manu
