Evergreen Conifer that has a significant problem?
Hello - We have an evergreen conifer, apprixmately 40 feet tall, that appears to have a significant problem. There are substantial number of branches that are either dead or the needles are a mixture of brown and green (see pix). There are other areas of the tree that seem fairly healthy and are even getting new pine cones. Any thoughts on what we might do would be greatly appreciated. If you need any more information, please ask. Thank you in advance. Jim McCarthy

Thank you for writing.
The pictures are too distant to identify the tree or disease.
This could be white pine blister rust. https://extension.umn.edu/plant-diseases/white-pine-blister-rust
Needle blight https://extension.umn.edu/plant-diseases/dothistroma-needle-blight
It could be pine dieback.
At any rate, an arborist should be consulted to diagnose, check neighboring trees for disease and suggest management. https://extension.umn.edu/planting-and-growing-guides/how-hire-tree-care-professional
