I'm seeing signs of disease in the Mahonia, as well. Bacterial or fungal diseases are common in wet soils, and they can be hard to identify by pictures. The best way to identify the exact issue will be your local agricultural extension service.

In the meantime, treatment will focus on maintaining the disease. Fungicides and good sanitary practice will be your best bet. This means keeping any dead or dying debris pruned away and removed from the area.
