General System description
System name: SIMulating Patterns and Processes at Landscape ScaLEs
Acronym: SIMPPLLE
Brief overview
SIMPPLLE is a spatially-explicit, dynamic landscape modeling system for projecting temporal changes in the spatial distribution of vegetation in response to insects, disease, wildland fire and other natural and management caused disturbances. SIMPPLLE is designed to provide a balance between incorporating enough complexity and interactions in modeling ecosystem processes to provide an acceptable level of realism while making simplifications in the choices on required data input requirements, required computer platforms and computing time to be a management tool useful in collaborative planning processes.
Contents
Scope of the system
SIMPPLLE is designed to serve as a decision support system to help managers and resource specialists quantify and incorporate concepts that are often difficult to interpret for specific landscapes. Managers can use SIMPPLLE to help define and evaluate desired future conditions at landscape scales, to identify what parts of a landscape are more prone to disturbance processes over a given time frame, and to help design and evaluate different strategies for achieving desired future conditions.
SIMPPLLE is implemented with ecological knowledge associated with geographic zones. Currently all the geographic zones are within the United States:
Geographic zones: Forest Service – Westside Region One, Montana and Idaho; Forest Service – Eastside Region One, Montana and Idaho; Sierra Nevada - Yosemite National Park, CA; Southern California; South Central Alaska - Kenai Peninsula, AK; Gila National Forest, NM; South West Utah; Michigan; Colorado Front Range; Colorado Plateau; Western Great Plains Steppe; Mixed Grass Prairie; Great Plains Steppe; Teton – Northwest Wyoming; Northern Central Rockies;
However the underlying object design of the system makes it possible to create new geographic zones for other ecosystems throughout the world.
System origin
SIMPPLLE was developed by Jim Chew, USDA Forest Service, as a management tool for the Northern Region of the Forest Service(Chew 1995, Chew and others 2004). Through the Joint Fire Sciences program (http://www.firescience.gov/) it was expanded into eight other geographic areas to test it and other models’ capabilities to design and evaluate fuel treatments at landscape scales (Weise and others 2006). Additional work with the FRAME project in Mesa Verde National Park (Turner and others 2008) has expanded the system into the Colorado Plateau. Work with the Ecosystem Management Research Institute (http://www.emri.org/) has expanded SIMPPLLE into grassland ecosystems.
The initial release of version 1.0 was in 1997. The current version available is 2.5. Version 3.0 is under development with USGS and Northern Arizona University, “Regional Dynamic Vegetation Model for the Colorado Plateau: A Species- Specific Approach”, http://www.niccr.nau.edu/cobb_abs.html
SIMPPLLE has been used for Forest Service project planning (Slaughter and others 2004), resource management planning on both National Forests (USDA 2008) and Bureau of Land Management lands (USDI 2005), for ecosystem assessments on National Grasslands (Haufler and others 2009) and in State wildlife management plans (State of South Dakota 2006). SIMPPLLE was utilized by a group of timber companies and conservation organizations to prepare a land management approach for the Beaverhead-Deerlodge National Forest (Ecosystem Resource Group 2006).
Support for specific issues
Is the system designed to take into account specific uses? E.g. guidance on ways to characterize biodiversity, economic-biodiversity tradeoff analysis methods, risk assessment methods, landscape analysis methods, timber harvest effects, climate change effects, biological effects (pests, pathogens, invasives), fire,...
Support for specific thematic areas of a problem type
- Silvicultural
- Certification
- Conservation
- Restoration
- Transportation
- Development choices / land use zoning
- Policy/intervention alternatives
- Sustainability impact assessment (SIA)
Capability to support decision making phases
(NOTE I do not quite know what to do with this, as I do not understand it myself, although it seems related to system use)
(Click here to see a more detailed explanation)
- Intelligence (+ explicit description of the support given by the DSS)
- Design (+ explicit description of the support given by the DSS)
- Choice (+ explicit description of the support given by the DSS)
- Monitor (+ explicit description of the support given by the DSS)

Data and data models
Typical spatial extent of application
Define the scale of use for the application (user defined, regional, multi-owner forest single ownership forest, Multiple scale interaction)
Forest data input
Describe the basic forest input (forest level, stand level, or individual tree level), and appropriate meta-data, such as data provenance (Areal coverage, Sample of plots, stands, Contiguous forest cover). GIS information is to be considered here, namely include cover tyes and type of information (raster or vectorial, necessity of topological information) If necessary describe surrogate sources of information
If necessary describe other types of required data (economic, social)
Type of information input from user (via GUI)

- provides standard data import/export formats

Abilities to address interdisciplinary, multi-scaled, and political issues
Evaluate interactions between different basic information types (biophysical, economic, social). Produce coordinated results for decision makers operating at different spatial scales facilitate social negotiation and learning
