Dear Ecologists, We are presently compiling a list of programs (or initiatives) that monitor or measure (trends in) invasive alien species/exotics/non-indigenous species at a national level or larger. An example would be the percentage of selected invasive and noninvasive native bird species that had increasing populations in grassland/shrubland ecosystems during 5-year intervals to describe the state of Grasslands and Shrublands by the Heinz Centre (see http://www.heinzctr.org/ecosystems/grass/non_nat_brds.shtml).
Should you know of any webpages, programs, or peer-reviewed papers that use alien species as an indicator to measure the State of the Ecosystem at a large spatial scale, we would pleased to hear about it. Thanks very much in advance. I am looking forward to your input, Jesse Kalwij Post-doc.fellow Dept. of Entomology / DST-NRF Centre for Invasion Biology University of Stellenbosch Private Bag X1 Matieland 7602 South Africa Fax: +27 (0)21 808 4807 http://academic.sun.ac.za/consecol/Jesse.Kalwij/welcome-en.html
