Develop a process-based model of tree and stand growth for the Tahoe Basin, and then model fire risk and fire spread for current stand conditions and the structural treatments under three different carbon dioxide scenarios to determine which fuels treatments reduce the risk of catastrophic fire and best meet location-specific goals.

-
. In the Lake Tahoe Basin, where there is a high density of development, managers are limited in their options for reducing forest fuels using prescribed fire. Compounding this management challenge is the expectation that changes in climate resulting from increasing greenhouse gas levels will exacerbate the threat of catastrophic fire.

| 07/16/2017 10:13 AM | Kiara Cuerpo-Hadsall | Objectives: The purpose of this study was to quantify the influence of predicted changes in climate on live tree carbon stocks, as a function of species-specific carbon stock changes, in a Sierran mixed-conifer forest by accounting for both biotic and abiotic influences on growth. Additionally, we sought to determine the carbon stock implications of treatments implemented to reduce the risk of high-severity wildfire and their interaction with climate impacts on growth. |

| 07/16/2017 9:56 AM | Kiara Cuerpo-Hadsall | Findings: • Outputs were produced for numbers of trees, basal area, stand density index, and carbon stock. • In the recursive partitioning analysis, the most influential factors were general circulation model (GCM), forest type, and simulation period. The partitioning based on GCM was a function of the temperature and precipitation projections specific to each GCM-emission scenario combination. The partitioning based on simulation period was a function of projected climate over a specific time period. • The projected late-century reduction in winter precipitation, an important source of moisture for tree growth, was greatest from the Geophysical Fluid Dynamics Lab coupled model (GFDL) under the A2 emission scenarios. While all projections were for increasing temperature throughout the century, the greatest increases were from National Center for Atmospheric Research Community Climate System Model (CCSM3) and GFDL. *** See www.fs.fed.us/PSW/partnerships/tahoescience for additional findings. |

| 07/16/2017 9:55 AM | Kiara Cuerpo-Hadsall | Management Implications: • The large influence of GCM on carbon storage suggests that reducing uncertainty in modeling forest growth response to wildfire mitigation treatments will require further refinement of climate projections. However, our results also suggest that there may be some capacity to leverage treatments to improve adaptive capacity for forest C sequestration as evidenced by the scenarios where there was little difference between control and thin-only treatments by the end of the simulation period (e.g. mid-century CNRM-A2). • Our results show that changes in species-specific carbon stocks varied by GCM and emission scenario and that trade-offs between species caused a smaller reduction in stand-scale forest carbon stocks than would have occurred had all species been similarly impacted. • Our results indicate that species-specific growth sensitivity to climate and the resultant carbon stock changes vary considerably as a function of the climate projections for a given emission scenario. *** See www.fs.fed.us/PSW/partnerships/tahoescience for additional management implications. |
