Journal of Forestry, 01/99.
One interesting article, which I have referenced below.
The authors write about the need and the practice of saving wood and fiber at logging sites, from slash to snags (standing dead trees). The article includes a brief management guide, which is a set of instructions. The final entry is "Experiment with your own ideas."
Relevance to Arboriculture and Urban Forestry:
We are wont to automatically remove dead trees, as a money-maker or as a hazard reduction. By doing so without due consideration, we remove habitat for other species, and also we remove organic matter from our yards that will never become in situ humus.
Best Management Plan, in my opinion, is to reduce hazards by doing the minimum that reduces the hazard to an acceptable level.
For example, reduce height of dangerous trees to a safer level, take off dangerous branches, blow chips on site, leave rotten logs where they lay.
Each time we diminish the components of the forest, we reduce the planet Earth.

Coarse Woody Debris: Humans and Nature Competing for Trees
By John M. Hagan (e-mail: jmhagan@ime.net) and Stacie L. Grove

Dead wood is usually the last thing foresters and forest products companies want to see in their forests. However, before humans discovered so many practical uses of wood, dead and dying trees were basic to forest development. Not surprisingly, many plants and animals evolved dependencies on dead wood. Today, with maintaining biodiversity a primary goal of forest management, foresters are confronted with seemingly contradictory goals: prevent or minimize agents that damage trees, but also maintain biodiversity, including the species that need dead wood.

Certainly we should leave dead/dying trees in wooded areas whenever possible! The habitat value is outstanding... and irreplaceable. I have been doing this since the 1970's and recommend it often in development inventories and on HOA's properties. Some people think it's a crazy thing to do; others love it.

Heard some arborists in England (at ISA conf) who re-erect trees that have fallen and secure them to other trees. They also cut longitudinal sections from trees, create cavities, and resecure the sawn-out piece to complete the cavity.

"Cleaning-up" the woods, as a general practice, has got to be a mistake!

Who said, "A dead tree is more alive than a live tree."

What about the broodtree issue?

Obviously there are situations that would preclude leaving debris. An elm treated with cacadylic acid, or with the bark stripped off would be okay, though.

(Our elms are mostly gone... it's a moot point!)
