Good trees, bad locations

The last of the five birch trees that were in our front yard bit the dust Wednesday. The tree crew took just 45 minutes to fell it, the branches hitting the muddy lawn with a loud "thud" as they were cut off.

Birches are prized for their white bark but the branches can be brittle.

But the fifth tree was on the opposite side of the yard, the southern side, and it did a great job shielding some of the garden and house from the afternoon sun. (Of course it also dropped tons of small leaves in the fall.) The squirrels used it as part of their arborial highway, and the scrub jays often sat in the upper branches, keeping watch against predators while their nestlings slept in the nearby fern pine tree.

It takes a long time to kill a tree, so I think the big California drought of 2011-2017 spelled the eventual doom of this birch tree.

This birch tree in a Carmichael neighborhood looks healthier than the one we had removed this week.

My current neighborhood was built between 1962 and 1970, and some stands of birches remain, but they are looking their age. And people still plant them -- a house a block away has two relatively young trees growing right in the lawn.

Tree fans contend that there are no bad trees, only bad tree locations, and I'm inclined to agree.

Here's the truth of the matter: Birches are natives of very cold climates. They need moist soil, and their shallow, wide-spreading roots are vulnerable to heat and drought. That makes the white birch one of the worst trees you can plant in drought-prone California. The aphids, of course, are another issue.

This last birch put out roots under most of our front lawn, but the irrigation cutbacks were clearly hurting it. The leaves this past year were much sparser than in past seasons, and a few of the branches in the crown didn't have leaves at all. My neighbor was afraid it was going to fall on her house -- though it wasn't leaning -- so we had our favorite arborist come look at it.

He agreed that the tree was slowly failing and could lose the top in a heavy windstorm. Birches in our climate, he noted, have a life span of 15 to 20 years or so. And this tree was at least 25, probably more. He said we could have it topped or have it removed. I've seen a few pathetic topped birches in the neighborhood, and I didn't want that.

So down it had to go, and yesterday it did.

The yard seems more exposed, so I probably will plant some shrubby native perennials in that area, but not another tree. There are utility lines buried nearby and I don't want to chance disturbing them.

If you have a birch in your yard, keep a close eye on it. And while you're at it, get to know the other trees around you, to forestall future questions. A tree that doesn't match our climate can survive -- with extra care.
