General System description
System Name: Landscape Management System
Acronym: LMS
Brief overview
LMS coordinates the flow of information among existing growth models, computer visualization software, and analysis tools to allow the user to simulate the growth and management of stands and landscapes and to view the outcomes.
Contents
Scope of the system
The Landscape Management System (LMS) and companion tools are an evolving set of computer applications designed to facilitate the analysis and communication of landscape-scale forest management decisions. They use standard inventory information to integrate many analyses and predict complex changes in stands and landscapes over time. The Microsoft Windows computer-based system coordinates the flow of information among existing growth models, computer visualization software, and analysis tools to allow the user to simulate the growth of stands and landscapes and to view the outcomes using a "point-and-click" system. Preferred management scenarios are developed in LMS by evaluating multiple projections that can be done either at the stand or landscape level. Companion tools allow the user to develop and compare many alternatives very rapidly.
System origin
In the late 1980s, the state government of Washington asked Professor Chad Oliver for help in managing their forests for multiple values because of intense political conflicts between timber and wildlife advocates. It did not begin as a software project but rather as an effort to organize theory and information relevant to the problem. The complexity of information involved led toward the development of a computerized DSS. Support from a local representative to the national government helped secure financing from the US Forest Service, and an initial version was released publicly in 1997.

Decision Support
Definition of management interventions
[Define what is available for the manager to intervene in the forest: time of harvest, plantations, thinnings, reconversions...Existence of prescription writer, simple enumeration of all possibilities, scenario simulation , etc.]
Management interventions are those provided by the FVS component system, including harvests, thinnings, prunings, site preparation, planting, prescribed fire, fuel treatments, etc. Any number of activities can be scheduled at any time during a simulation. Activities may be scheduled to occur in a particular year, or they may be scheduled to occur when a specific condition is met. For example, a harvest could be scheduled for 2035 and a planting scheduled for 2037, or the harvest could be scheduled to occur when the stand basal area exceeds 100 and the planting could be scheduled to occur two years later. Management can be as simple or complex as the user desires. Simulations are easily edited and re-run to gain knowledge of a range of possible scenarios.
Typical temporal scale of application
Generally used for longer-term strategic decisions, but also sometimes used for near-term tactical decisions. The simulation component, FVS, typically uses 10 year intervals, but the user can specify the number of years in each cycle, and can include up to 40 total intervals in a simulation.
Types of decisions supported
Decision-making processes and models
- Simulation
- Evaluation
Output
Types of outputs
- 20 standard tables: standing and/or harvested volume, inventors wind hazard, habitat suitability for different species, costs and returns and other features.
- Visualizations of conditions via companion programs: landscape (Envision) and stand (SVS)
Spatial analysis capabilities
LMS does not perform any spatial analyses itself, however, it does include a landscape visualization component (Envision). Envision requires a stand boundaries polygon layer (in ESRI shapefile format) and a raster digital elevation layer (in PCPlans Binary DTM format).
Abilities to address interdisciplinary, multi-scaled, and political issues
Produces coordinated results for decision makers at different scales: Capability to evaluate landscapes as an aggregate of stands.
Facilitates social negotiation / learning: Useful in demonstration of silvicultural alternatives for evaluation of alternatives.
System
System requirements
Operating systems: Windows2000, WindowsXP, Windows Vista
Other software needed: Includes FVS growth models, and WinSVS & Envision visualization systems.
Development status: Regularly distributed
Architecture and major DSS components
[Describe the basic architecture of the system in software and hardware. Desktop client-server, web based, as well as the integration with available systems.Basic data flow, focusing on retrieval of required input and propagation and implementations of decisions. Mention its modular and scalability capabilities.]
LMS is a Microsoft Windows program written in the Python programming language. It connects to its companion programs via???. Basic information flow is described in McCarter et al. (1998).
Usage
LMS has been used by governmental agencies at the state and federal levels (and also by private landowners & consulting foresters?). A number of cases are available on the website:
- Chernobyl
- Indian Island - DoD, NDCEE
- Maine
- Mid Forest Lodge, MI
- Pack Forest, WA
- San Carlos Apache, AZ
- Satsop, WA
- Solduc, WA
Computational limitations
[Describe the system limitations: e.g. number of management units, number of vehicles, time horizon.]
The FVS growth simulation subcomponent is limited to projecting 40 periods.
User interface
User interface quality: Designed for use by non-experts
Complexity of system / user interface: Medium - the underlying tools are fairly complex, but LMS simplifies their use by providing a common interface and connections between them.
Documentation and support
Documentation: Windows Help File, Tutorials (pdf) on-line or distributed on CD-ROM.
Training: 10+ tutorials are available online. Online discussion group. 2-3 day training sessions offered (see web site).
Installation
Prerequisite knowledge needed: Forestry knowledge useful. Microsoft Excel useful for customized analysis.
Cost: Free
