Answer: Unfortunately, based on your description I am not able to tell you what is happening to your pine trees. Pines are potentially subject to a wide variety of pests and diseases, and the dry winter may have also taken a toll. I would suggest you consult with a local professionally trained nurseryman for a diagnosis, or contact the UMASS Plant Diagnostics office. Here is contact information, including the phone number.

I'm sorry I can't be more specific for you.
