During the course of the project, this page will be populated with field guides and edited volumes coming from our meetings and workshops as well as annual reports.

In the early phases of this project, we included a citation and link to each paper online (see bottom of page).  As our membership and research has grown, so too have our publication lists.  It has become impractical to list each publication separately.

  • In 2019, more than 70 publications acknowledged IGCP 653.  The full list is here.
  • In 2018, more than 92 publications acknowledged IGCP 653.  The full list is here.
  • In 2017, more than 37 publications acknowledged IGCP 653.  The full list is here.
