Challenges for Landscape Management
large areas and long time frames complexity
• spatio-temporal feedback between pattern and process
many sources of uncertainty• spatial information, key processes, natural variability
competing values• cultural, conservation, resources, tourism• lack of optimal solutions
Yet, landscape managers must make decisions– land-use, sustainable resource management, endangered
species recovery, natural disturbance …
– Extent: ~2 million ha
– spatial data• forest cover, roads, .etc
• management zones
– non-spatial data• growth and yield
• little ecological data
• little natural disturbance data

A “toolkit” approach to landscape modelling
Different models are best applied at different scales and for addressing different questions
• Static - GIS, inventory of current conditions
• Dynamic - changes due to succession, management, natural disturbance
• Stand scale - fine-scale processes, growth and yield
• Landscape - timber supply, habitat supply, pattern analysis
Need ways to links models and tools of different kinds

Model “Toolkit” Approach
• Flexible association of models and model-building tools
• Coupled suite of relevant indicators reflecting values (ecological and social)
• Goal is the rapid assembly and development of models to address specific questions

SELES: Spatially Explicit Landscape Event Simulator
A general tool for building models of landscape dynamics
– a language for specifying models of landscape dynamics
and
– a simulation engine for running these models
SELES: paradigm
share knowledge to build capacity• SELES is free
• models built in SELES are transparent
• courses are periodically given
• models built in SELES should be shared

Landscape Scale ObjectivesLandscape Scale Objectives
• scenarios: project landscape conditions
– integrate processes: spatial timber harvesting, fire, succession
– timber supply analysis
• scale: vertical and horizontal
– use results from stand-level and other landscape scale analyses
• indicators: produce ecological / timber indicators
– generate spatial time series: pipelining
– to assess spatial patterns of habitat

How to link tools: meta-modellingHow to link tools: meta-modelling
• file transfer
– non-spatial files
– spatial time-series
• parameters and scenario definition
• model embedding
• invocation
pipelining,loose coupling
tight coupling
How to make an effective toolkitHow to make an effective toolkit
• people
tools used reflect skills of team and capacity building goals
• systems perspective
scale, complexity
• tool selection
