Added: October 31, 2008In storm damage and tree failure assessments, estimating residual strength of damaged trees is difficult and filled with complex, dynamic interactions between the soil, tree, and environment. To help tree specialists appreciate tree biomechanics, this publication was developed to present the maximum relative strength values for two unique, ideal situations--neutral plane faults leaving two stem halves and four stem quarters. This theoretical view can help better understand certain mechanical forces and resistances.

Added: July 26, 2008If you are lucky, you live in one of those parts of the world where Nature has one last fling before settling down into winter's sleep. In those lucky places, as days shorten and temperatures become crisp, the quiet green palette of summer foliage is transformed into the vivid autumn palette of reds, oranges, golds, and browns before the leaves fall off the trees. On special years, the colors are truly breathtaking.
- Uptake and Reduction of Nitrogen in Trees

The Society of American Foresters has published a comprehensive, peer-reviewed report on the status of America's forestland. This 68-page report outlines the latest facts and figures in easy to read graphs, charts, tables, and supporting commentary. The State of America's Forests is the most definitive, one-source compilation of credible forestry facts touting more than 50 sources and peer-review by academia, non-governmental organizations, and the USDA Forest Service.
- Leyland Cypress
-
Leyland cypress is now grown in all southern states, and is becoming desirable for use as a Christmas tree species in that region.
- Interpreting Streamflow Forecasts
-
Each month, five forecasts are issued for each forecast point and each forecast period. Unless otherwise specified, all streamflow forecasts are for streamflow volumes that would occur naturally without any upstream influences. Water users need to know what the different forecasts represent if they are to use the information correctly when making operational decisions. The following is an explanation of each of the forecasts

Added: November 05, 2008Soil compaction is a complex set of physical, chemical, and biological constraints on tree growth. Principle components leading to limited growth are the loss of aeration pore space, poor gas exchange with the atmosphere, lack of tree available water, and mechanical impedance of root growth. There are significant genetic differences between tree species for tolerating various levels of soil compaction.
