Can they be saved or should I remove them?
Perhaps they just need pruning? Here's some info about how to do that:

several acres lot in middle of old forest; reasonable soil; slightly less than full sun
These articles may help although it sounds as though you are dealing with a large area, which will be difficult to provide control.

Dear Garden Advice, I planted some Cham. laws 'Columnaris' conifers in Feb/March. However one particular tree is browning rapidly. The change is very apparent from a normal adjacent tree. Id be grateful if you could provide diagnosis and respective solutions. Regards, Yas
There is a fungal disease that causes root rot. Make sure the soil is very well drained. Here are other possibilities:

I have big maples and other trees at the perimeter of my lot. I want to put cedar hedge. I am wondering if the roots from the trees will let the hedge grow. Thanks
Not only would there be a tree root issue, but a competition for nutrients issue, as well as lack of full sun.
We planted a cedar hedge, but they died. Tried again this year. We followed all the advice given us. Improved drainage with drainage pipes, correct spacing apart, planted a bit higher off ground with root ball still in the sack cloth. Have a drip hose. Drainage working well. Used bonemeal and good soil. Yet one tree has already died the season and one is not looking good. What on earth are we doing wrong??
The cloth sack probably needs to come off. Are they in full sun? Also make sure they aren't getting too much water. Another possibility is that the previous trees died of a soil borne disease and the organisms survive in the soil and are infecting the new trees.

I have supported them with bamboo sticks which are to small now.do I just let them grow up without support now and let them lie over hanging and on the bed or support to a certain high.
If they fall over when you remove the stake, I would continue to stake them till they are erect enough not to fall over.
I have a 2 year old Cedar Pine tree that was transplanted from a small rocky area to a pot to be used as a bonsai. During the summer, the center top became discolored, pale brownish, and the branches and needles began drooping. The tree has also become a pale green versus the dark vibrant green it was upon transplanting. I don't know what is wrong or how to return it to health. I also transplanted 2 smaller/younger trees from the same area to pots and they haven't developed this problem. Any ideas, suggestions and/or advice, please? note: I tried adding pics but the system kept failing the upload.
It sounds like the tree was too mature to move, or too many roots were damaged in the process of moving. The only way to save it is to ensure that it receives perfect care, if the roots aren't too damaged.
Unfortunately, since the photos wouldn't upload, I cannot see whether this was a cedar or a pine. I will include articles for both.
