Threshold Categories

  • Forest conditions at the time of Euro-American settlement and prior to the extensive Comstock logging era (hereafter pre-Comstock) are increasingly used as a point of reference for ecologists and managers in the Lake Tahoe Basin (LTB) for characterizing the range of variability in ecological processes and structures at a time when ecosystems were less affected by people.

07/23/2017 8:25 PM Kiara Cuerpo-Hadsall Objectives:

The overall goal of this project was to develop spatially-explicit reference conditions for pre-Comstock forest landscapes and associated fire regimes for the Lake Tahoe Basin that can be used by land managers in the ecosystem restoration planning and implementation process. An understanding of the spatial variability in pre-Comstock forest characteristics is essential for understanding if and how planned stand-level activities (mechanical fuel treatments, prescribed burning, etc.) scale up and contribute to restoration of functioning forest landscapes (i.e., wildlife habitat, forest health, hydrologic conditions, etc.).

07/23/2017 8:25 PM Kiara Cuerpo-Hadsall Findings:

• Contemporary basal area was greater in the present day forest than in the modeled pre-Comstock forest. However, previous work suggested that the basal area in the reference Red Fir and Lodgepole Pine forest types were greater than or equal to the contemporary period.and reported that the species composition and diameter distributions differed between the contemporary and reference stands, stating that reference red fir and lodgepole pine trees were larger in diameter than contemporary trees and there were few reference trees < 30 cm in diameter.

• All forest types saw some increase in percent coverage at the expense of the Red Fir forest type, which decreased by 38.9%.

• The change in percent cover of the Red Fir forest type was the greatest change in forest composition in the entire basin.

• ArcGIS layers of pre-Comstock forest structural types (and subtypes), fire return interval, and surface fuels that are available as .kmz files viewable in Google Earth.

• Stand Visualization System (SVS) and EnVision simulations of pre-Comstock forest structural types.

• Spreadsheets containing density (stems/ha) and basal area (m2/ha) by species and 30 cm bin for each main forest structural type and subtype.

• Summary tables of data reported above.
