National integration and collaboration and implementation of the Australian Terrestrial Carbon Cycle Science Plan

We will address how to effectively integrate Terrestrial Carbon Cycle research in Australia across ARC NESS, CSIRO, ANSTO, NCAS, universities and other institutions and how this may be facilitated through the national “Blueprint for Australian Terrestrial Carbon Cycle Science Plan”. Short talks with ample discussion.

Engagement with TCCSP and ACCESS. How can the wider community contribute to the TCCSP and ACCESS. Specifically we will address the capacity and priorities for the following (including key research issues, expertise, areas for collaboration, limitations, funding opportunities), for the following areas:
