Calculating How Fast Trees and Forests Grow

That might sound like a rather dry, technological subject, but it is, obviously, quite important in relation to wood production from forests.

Rants from the Hill: Towering Cell Phone Trees

Rants from the Hill is cross-posted from High Country News For a couple of years back in the 1970s, when I was a little kid, my family had an artificial Christmas tree that I thought was incredibly cool. It was fun to put together, with a central “trunk” that resembled an oversized broomstick, full of downward-angled holes into which the “branches” were fitted.

Superstorm Facilitates New Forest Growth

  Travis Beck, author of the new book Principles of Ecological Landscape Design, recently wrote about one of Hurricane Sandy's more positive effects. Here's an excerpt:   Superstorm Sandy reminds us, however, that humans are not the only ones to fell trees. Her strong winds uprooted or snapped the trunks of over one hundred trees in the Forest. Where these trees fell, gaps now exist in the canopy, creating opportunities for the next generation of trees to grow.

Ghost Trees

The standing dead trees were everywhere, their boles weathered silver where the bark had peeled. The carcasses of their fallen comrades littered the understory, with few aspen sprouting from the deadfall. The occasional mangled saplings we observed provided graphic evidence of heavy elk browsing. Recently, I explored this stand of ghost trees on Colorado’s High Lonesome Ranch (HLR), accompanied by some of the finest aspen ecologists in North America.

Aldo Leopold and the Mark of the Wolf's Tooth

In the early 1900s, while cruising timber as a young forester, American conservationist Aldo Leopold, founder of the science of wildlife biology, encountered a female wolf with her pups. The common wisdom of that era was that the only good predator was a dead one, so he and his crew opened fire. But as he stood there watching the “fierce green light” fade in the wolf mother’s eyes, he felt a sharp, surprising pang of remorse. It would take him decades to parse out his feelings about her death. In 1935, Leopold bought an abandoned farm in southwestern Wisconsin as a hunting reserve.
