Table 1. Brief descriptions for specific modeling tools applied to the Labrador case study (Figure 5). More details, modeling examples, and links to supporting information are in the Appendix.

Model Name Brief description Role in Labrador District 19A meta-model
SELES A general tool for building grid-based models of landscape dynamics (Fall and Fall 2001). Implement the 20-year plan, perform simulation-based timber supply analysis (D19aLM), and facilitate inter-model communication.
LINKAGES A forest ecosystem “gap” model that simulates tree establishment and succession as a function of soil water, nutrient dynamics, and climate (Post and Pastor 1996). Estimate the probability of tree species establishment in LANDIS-II.
Canadian Forest Fire Behavior Prediction (FBP) An empirical model used to predict fire spread rates and behavior based on fuel types, weather, topography, and geographic location (Forestry Canada Fire Danger Group 1992). Parameterize relative fire spread rates within different forest cover types for use in landscape disturbance models (e.g., LANDIS-II).
LANDIS-II A raster-based, landscape-scale disturbance and succession model that trades mechanistic detail for the ability to simulate over large landscapes and long time scales (Mladenoff 2004). Explore interactions between management and natural disturbance in terms of impacts on likely tree species and age patterns and composition.
SORTIE A spatially explicit, individual-tree, neighborhood-scale model that simulates stand development as an outcome of interactions among trees (Pacala et al. 1996). Capture fine-scale succession processes to estimate changes in tree species composition and explore dynamics of partial harvesting regimes.
Patchworks A tool for producing spatial harvest schedules (http://www.spatial.ca/products/index.html) Produce harvest schedules, and compare with scenario-based approaches to timber supply analysis.
Real Options A numerical analysis approach used in economics to inform decisions with irreversible consequences that affect a real asset (Dixit and Pindyck 1994). Explore economic aspects of planning, such as the decision to stop timber harvesting when it may trigger the extirpation of resident caribou (Morgan et al, unpublished).
BAP toolbox A set of indicator models for assessing alternative management strategies in terms of biodiversity values (Doyon and Duinker 2003) Assess the consequences of different management scenarios on biodiversity using both coarse- and fine-filter approaches.
