Christmas tree needle sampling to evaluate nutrient need is an established practice. Data to support the recommended fall sampling time in Oregon and Washington was not found. In addition, the recommendation for needle sampling of Fraser fir in North Carolina was made without data from winter months. The goal for...
Forest certification—or, as it is sometimes called, green certification—aims to identify forestland that is managed to meet agreed-upon standards and, sometimes, to label products originating from those forests. The underlying goal of forest certification is to promote forest practices that are environmentally, socially, and economically sustainable over the long term....

Advances in forest carbon mapping have the potential
to greatly reduce uncertainties in the global carbon
budget and to facilitate effective emissions mitigation strategies
such as REDDC (Reducing Emissions from Deforestation
and Forest Degradation). Though broad-scale mapping
is based primarily on remote sensing data, the accuracy of
resulting forest carbon...
