Ecological Forestry

SERDP and ESTCP efforts are developing the science, models, tools, and methods to put into practice the principles of ecological forestry on DoD lands. This approach to forestry perpetuates ecosystem integrity at landscape scales while continuing to provide realistic military training and other ecosystem services. Included here is identifying the appropriate use of fire for fire-adapted ecosystems and the necessary models and decision support tools needed to support its use.

Growth and Carbon (C) Sequestration Model for Even-Aged Longleaf Pine (Pinus palustris) Stands

Model / Software and Guidance

This Excel based model enables the user to simulate stand dynamics of planted longleaf pine (Pinus palustris) forests under different management scenarios. The model facilitates simulating the following:

  • Growth and Yield (survival, trees/ha or trees/acre; dominant height, m or ft; basal area, m2/ha or ft2/acre; total merchantable volume outside and inside bark partitioned into three wood products: sawtimber, chip-and-saw, and pulpwood, m3/ha or ft3/acre).
  • Pinestraw Production (pinestraw production from current year needlefall, Mg/ha or tons/acre).
  • In Situ Biomass C Stocks (aboveground, coarse roots, forest floor, coarse woody debris, standing dead, and understory stocks, Mg C/ha or tons C/acre).
  • Ex Situ C Stocks (dynamics of C sequestered in forest products, Mg C/ha or tons C/acre).
  • Stand C balance (In Situ + Ex Situ – Silviculture Emissions). Emissions from silvicuture include the C costs (Mg C/ha or tons C/acre) of activities such as planting, site preparation, prescribed burning, harvest, and transportation.
  • Effects of prescribed burning on forest floor, coarse woody debris, and understory biomass.

The webinar provides step by step instructions on input parameters, how to navigate the excel spreadsheets, and model outputs.
