Cedrus deodara 'Karl Fuchs' / Karl Fuchs Himalayan cedar
Cedrus deodara 'Karl Fuchs' is a large growing, robust selection of Himalayan cedar with remarkable attractive silvery-Blue foliage on layered branching with nodding tips. After 10 years of growth, a mature specimen will measure 10 feet (3 m) tall and 6 feet (2 m) wide, an annual growth rate of 6 to 8 inches (15 - 20 cm).
This cultivar originated as a seedling selection made in the mid 1970s by Günther Horstmann nursery, Schneverdingen, Germany. It is among group of seedlings selected from seed sourced from Paktia provence, Afghanistan. These plants are known for exceptional hardiness and resistance to storm damage. Karl Fuchs is the name of the name of the collector/explorer.

When you say a mature specimen will reach 10', do you mean that is the maximum height it will reach? Or will it keep growing taller?
no, absolutely not! Like all woody plants, conifers will grow at a similar rate for many decades, if not centuries. With that, this cultivar will grow at a yearly rate of 6 - 8 inches for an extremely long time. Unless you're extremely talented with pruners, no conifer will grow to a specific height, then stop (unless of course it's dead).
For the last couple of years at least that I recall, the branches on the lower half of the tree are very sparse with quite a bit of the pine needles along the branch turning brown. Other parts are green and appear to have a little light green new growth. Do you have any idea what is wrong. I would hate to lose this tree. The top half is beautiful but I'm afraid it might be working up the tree whatever is going on. It gets full sun and is watered regularly, plus I live in the NW, so it's gets plenty of rain. I can't see any signs on the trunk other than cracking bark. Appreciate any help. Thank-you.
