Scale is a prominent topic in restoration and adaptive management
Influences conclusions and extrapolations
Scale related to hierarchy; hierarchy theory provides a framework (consider focal level; level above constrains; level below explains [mechanisms])
Extrapolation from fine to broad scale is straightforward if areas are homogeneous and relationship linear; spatial heterogeneity present, but need to know random vs. structured pattern; fractals and other methods possible if processes and constraints do not change across scales
Extrapolation a very difficult problem with spatial heterogeneity and nonlinear relationships (no general solution at present)
Just because you may not be able to scale up with great accuracy is no excuse for ignoring restoration and adaptive management problems at the landscape level !
