Evergreen Tree Trouble: Loosing more needles than normal
I have several large evergreen trees in my yard, not sure what kind exactly. This year I noticed they are dropping more needels than I would think is typical. I've included some pictures, can anyone suggest what might be causing this? I don't want to loose these trees. There hasn't been a huge drought or rainfall. There are some moles I believe in this area and some fungus at times on the ground.
Any suggestions is apprecieated.

Evergreen Issue
The picture is small but it appears to be seasonal needle drop. If the yellowing of the leaves is more on the inside of the branches and the tips are green then this is part of nature. I have seen this happening on a number of trees in the area.
Look up seasonal needle drop and see if that appears like your problem.

Follow Up
This is not seasonal needle drop. The tree appears to be an Austrian Pine. The most common problem with them is a needle disease. I am attaching a publication from K-State with pictures and a description of the problem. Hope this helps. Branch samples may be needed to diagnose.
