The Forest Service's Forest Inventory and Analysis Program now has a field inventory of standing dead trees across the United States replacing models that generalize regional averages by broad forest types. Instead of missing the effect of disturbances, such as droughts and insect outbreaks, disturbance effects on standing dead tree biomass and carbon estimates can now be measured in yearly time steps rather than in decades.

In addition, beyond simply counting standing dead trees, emerging research on standing dead-tree wood-density reduction and structural deductions improves the accuracy of standing dead-tree carbon stock estimates. Emerging work to map these pools of biomass indicates that they are very prevalent in forests of the Western United States.
