AEM is currently under
development as an open source toolbox for the measurement of
ecological structure, function, and change across managed
landscapes. |
|
|
The
core of the
AEM system was developed
by Erle Ellis and his
collaborators to measure
long-term ecological
changes in managed landscapes in China and the
USA, starting in 1993. |
|
|
The core methodology is now under review for publication. On acceptance of the methods by peer review,
the complete and updated AEM
system
will be made available in The
AEM System section of this
website. |
|
|
A brief description of the
methodology is in a 2004 book chapter by
Erle Ellis. The chapter is available for download:

A prototype of the current
ecotope system was developed to measure ecological changes from
the 1930s to 1994 across a village in China. These
early methods are described in:
Ellis et al. 2000a.(download
pdf). More information on the early system is
online at:
