Why management that helps some landscapes harms others
Brittleness is a fairly new measure of ecosystem function that allows us to match land management to what each landscape needs.
The biggest difference in landscapes is how they respond to prolonged rest from disturbances such as fire and grazing:
Management that doesn't suit the landscape is the leading cause of desertification worldwide.

Landscape brittleness and productivity by Jim Howell. by Jim Howell. Introduces a better way of measuring brittleness that gives managers more information about what their land needs than Savory's original brittleness scale.
