| The
use of landscape metrics in landscape ecological investigations has
skyrocketed since the emergence of software programs like FRAGSTATS
in the mid-1990's. Until recently, much of the emphasis has been on
developing new methods for quantifying landscape patterns. Consequently,
a plethora of metrics have been proposed. This has created a double-edged
sword. On the one hand, the diversity of metrics now available allows
for myriad landscape patterns to be quantified effectively. On the
other hand, the great number of metrics available makes it incredibly
confusing to choose appropriate metrics among the many candidates.
Moreover, while considerable effort has been given to the development
of new metrics, comparatively little attention has been given to the
comparative evaluation of metric performance under controlled conditions.
In this book, we plan to provide a solid conceptual background
to the development and use of landscape pattern metrics. Specifically,
we plan to provide a conceptual framework for classifying types
of landscape patterns and classes of landscape metrics. Further,
we plan to describe and illustrate the behavior of a comprehensive
set of metrics and compare their performance under varying landscape
conditions. We also plan to describe the use of the revised FRAGSTATS
software program to analyze landscape patterns. Finally, we plan
to provide a step-by-step protocol for conducting a landscape pattern
analysis.
This book will be specifically targeted for scientists and managers interested
in the proper use and interpretation of landscape metrics. It will be suitable
as a supplement to upper-division and graduate courses in landscape ecology,
but it will be valuable reference for scientists and managers seeking a
better understanding of landscape metrics. We are currently working on
this book and hope to have it available by the end of 2006.
