LTD: Landscape Treatment Designer

LTD Overview

Prioritizing management strategies on large landscapes with multiple objectives is difficult. The Landscape Treatment Designer (LTD) is a program used to help design and explore spatially explicit landscape treatment scenarios. The LTD can be used to prioritize treatment location on small landscapes (project level implementation) to large landscapes (national forest to multi-regional planning efforts). The LTD allows planners to quickly test different strategies in terms of management priorities, tolerance of fire risk or loss, implementation time frames, and budget constraints. The analyses can reveal trade-offs associated with different management strategies and the resulting change in ecosystem services. Although the LTD was originally designed for fuel treatment planning, to fill the gap between fire modeling programs and planning systems in the fuel treatment planning process, it can be applied to fiber production, habitat restoration, and for other resource management problems. The LTD can be used to develop aggregated (coordination of treatment to build large patches or low-hazard fire containers for restoration) or dispersed treatment plans. The program can build a single treatment plan or be run iteratively creating a treatment priority map. In addition sensitivity runs can be completed to stepwise increase thresholds and/or constraints to better understand the impact on treatment plans.
