Native Plant ID Help

I would appreciate your help in identifying a few plants that are currently growing on my property in Pueblo West, CO. The first is a clump grass with purple/burgundy tips. The second is a yellow flower, and the last I understand is some type of artemisia.
Thanks so much!

How to remove bees in a very large maple tree in Denver

We see small swarming bees in a large Maple Tree in our front yard.
They've made a hole in a branch ... the hole is @ 5-7 inches in circumference.
We presume that we'll need a professional to handle this but don't know who to call.

Norway Maples losing bark on trunks and some branches and having some dead branches

I have two 15 year old Norway Maples. Both are losing bark & have branches dying from the top & south side. This has occurred for about 3 years or so.

One tree still has about 1 foot of growth on most branches but the bark has come off about half of the lower to mid trunk (equally on both sides, East & West) and on about 1/3 of the branches. About 10% of the branches mostly on the top middle & south have dried up & died (the recent snowstorm & freeze may have been a factor. On the other tree, half of the bark on the lower to mid trunk (all on the South side). The top 1/3 of the tree has or is losing branches and bark. It has about 6 inches of growth on most good branches.

What are the likely causes? A tree expert 2 years ago suspected root girdling and winter sun scald with the freeze of 3 years ago also a major factor. I am wrapping the trunks each winter now. We did have metal around both trunks from about 8 to 4 years ago to keep the squirrels off the branches but removed them. I do feed them spring and fall with ross root feeder pellets. The nursery said to trim off dead branches.

Pine Wilt Nematode

Hi there

We have a tree that has started turning brown at the top. One arborist insists that it is from Pine Wilt Nematode, One says it might be, and one says probably not. The two that say maybe, are trying to sell us on topping the tree and trying to save it with spraying and fertilizer. We're trying to figure out if thats only going to end in removing the tree anyway. We do not know when it started, as we noticed it the first time we sat on our deck this spring. Thoughts?
