Why would a large Balsam Fur tree get very red brown needles on one side (it’s 60 feet tall). Is it a needle cast disease? Fungus, bugs or environment?

Now that we know that the tree is upright: Is there a pattern to the reddening/browning? BF hold several years of needles. For branches beginning to redden, are older or more recently formed needles affected first? To be useful, we (or at least I) need to know a bit more about the symptoms/signs.

What side of the tree is it on. Fir are generally understory trees at least initially. If your tree is under drought stress then then needles on the south and south west sides are more likely to be affected.

Does it produce new growing tips each year? There is a disease 'fir needle cast' or rather a group of them lirulla (sic?) being one of them that infect 2nd year needles. This year's needles look fine. Last year's are infected. Spores are primarily moved by splashing. Generally trees outgrow it. I've never seen affect more than the bottom few feet.

All the needles are brown now, tree looks to be almost dead, still not sure the cause, but thanks everyone!

Possibilities:
* Severe drought
* Poisoned -- e.g. your neighbour didn't like all the shade and dumped a bag of salt under it.
* Drowned. Something created very saturated conditions and the roots died.
