The attributes of all features of the layer "STEP Vegetation - Thicket Solid" which intersect with the selected feature in the layer "STEP Protected Areas (type 1, 2, and 3)" (Bosberg Lacal nature Reserve) are shown in the Information Panel (Escarpment thicket). The map refreshes to indicate this feature in yellow.

If you attempted to select for feature that does not intersect with the selected feature the system will return with a dialogue box report that no features were found. In the example below we tried an interception of "Bosberg Local nature Reserve" and "South African National Parks".
