Weird title. The actual title is "Human activities and species biological traits drive the long-term persistence of old trees in human-dominated landscapes". Looks like the nonsense title here is the result of removing a bunch of words from the actual title. Maybe it was done automatically.

> identified which species were most likely to persist as old trees in human-dominated landscapes and where they were most likely to occur. We found that species with greater potential height, smaller leaf size and diverse human utilization attributes had the highest probability of long-term persistence. The persistence probabilities of human-associated species (taxa with diverse human utilization attributes) were relatively high in intensively cultivated areas. Conversely, the persistence probabilities of spontaneous species (taxa with no human utilization attributes and which are not cultivated) were relatively high in mountainous areas or regions inhabited by ethnic minorities.

Unsurprising results, but it's interesting seeing it quantified.

you must have access to this article.. looks like a paywall.

It seems rather important that the trees studied are in China and this is about natural history there. I was told casually that every natural forest in that part of the world has been substantially cut.. there is no "old growth" past some threshold.

Lastly, no mention of methods .. we are in an information age.

That part of China along the river Yangtze was unusually stripped of trees going from Chungking to Shanghai but there was grass growing. I've seen twin hills where one was left alone and the other stripped mined for metal to feed ww1, there no trees or grass grew. It may as well have been on Mar

HN's title limit is 80 chars so the submitter had to shorten it. I've taken a second crack at it now.

(Submitted title was "Human activities drive long-term old trees in human-dominated landscapes".)
