+Use weight painting to indicate which areas of the model are affected more or less the decimate modifier.

+  - Create a vertex group
+  - Go into edit mode.
+  - A slider called 'weight' appears, with a value of 1.
+  - Click the 'assign' button to set the whole model to weight 1.
+**Paint the areas you want to preserve**\\
+  - Switch to weight paint mode. The 3D model looks red. This is weight 1.
+  - Paint the areas you want to preserve.
+  - Set your brush to 0 to fully preserve the original resolution in those areas.
+  - Set your brush to a value between 0 and 1 if you want to reduce the resolution, but not as strongly as the rest of the model (0.4 for example).
+**Set up a decimate modifier**
+  - enter the vertex group in the modifier to see the result.
