Re: Cercis (continued)

Don: Not in any obvious way. The right hand side of the road, which is where the very dense, continuous "bank" of redbuds grows, is under a power line, where the growth has been cut back twice in the last 50 years. Before that, there may have been herbicide treatments. Before Europeans settled this ...

Re: Keeping people informed

Bob: I must join in to praise your work for NTS and the outstanding leadership you have been providing. I for one, have often wondered where we would all be here without you. I only wish I could make some decent contribution myself, but so far, for reasons I won't go into, I haven't been able. BUT, ...

Re: Cercis (continued)

Don: There is an amazing display of redbud along US Route 50 a few miles--maybe 6 or 10--east of Augusta, WV. It starts just before the road begins to ascend Cooper Mountain, or as it skirts the shoulder of the adjacent mtn. The road takes a fairly sharp bend to the left as you drive eastward. There...

Re: Keeping people informed

Bob: We talked about the need for research on the growth rates of older white pines some time ago. I am glad that progress is being made, and the capabilities of the new equipment will reduce the labor involved significantly, which is a big plus. I believe this research is extremely important. A par...

Re: General Sherman is NOT single stem origin. Hence, not th

An apology: In my previous post I said that the corkscrew redwood tree was a single. Well, not exactly. It formed, apparently from a stump of a previously growing redwood. Several trees sprouted from the old stump, and these joined at the base. The central, main trunk that rises highest seems to me,...

NTS folks: I don't have photos available right now, but in total I have probably spent 3 or 4 months in sequoia groves, and have stared up into the crown of the General Sherman tree, and many others, for some considerable time. I have also spent a good bit of time in the coast redwoods. I have alway...

Re: Forests shape effects

This reminds me of surface volume ratios, and their effects on a number of things, both in physics and biology. Not sure there is any significant analogy here, however. In temperate forests, the forest edges relative to the forest interior space has important consequences. Right now I can't begin to...

Re: A mix of trees is good

Don: The subject of communication between trees is not something I have studied. I won't dismiss the idea that trees can have some kind of communication, enabling "cooperative" or "mutually supportive relationships." But won't accept the idea until there are some rigorous, replicatable experiments t...

Re: A mix of trees is good

Bart: Here is a "tidbit" of sorts: the aspen trees are making a comeback in some areas of the west, where they have been disappearing. Why? The re-introduction of wolves. What, wolves? Yes, wolves are predators of elk, and elk, when too plentiful, eat too many aspen trees, thus.... In this vein, the...
