Lots of things are prickly or troublesome on my land. Some are useful but annoying.
A good example are the blackberries. They proliferate anyplace there is a disturbance and sometimes seem to have a malevolent intelligence. As you push through them, the branches whip backwards, hitting you in the back of the head and sometimes knocking off your hat. But blackberries are good in that they provide significant food for wildlife and habitat. You can eat them yourself. They taste good but they are small and you have to take a lot of thorns for your meager meal.
My last picture is a tree of heaven (Ailanthus altissima). This is nothing but trouble with no redeeming characteristics in a rural setting. There are some uses in degraded urban environments, since they grow fast and can grow almost anywhere. They are nearly impossible to eradicate. If you chop them down, they grow back more vigorously. There is no effective method I have ever heard about that does not require chemicals and even with this you cannot win a final victory. I have been spraying these things for years and go after them whenever I see them.
I was indolent with the one in the picture. I noticed the clump in the middle of the wildlife plot last year, but I didn’t have my sprayer with me so I left it. I went back last week. It had growing bigger and thicker and about a dozen little ones had sprouted as far as 100 yards away. I think I got most of them, but I am sure they will be back.
