This document discusses a collaborative book project involving 83 environmental professionals that described changes in Australian ecosystems based on long-term research. It included 14 chapters covering nine ecosystems, drawing from 35 core long-term studies. Key findings included detecting increased woodland bird populations and impacts of interventions like grazing control. The book aims to inform natural resource management by documenting ecosystem changes. Future work will maintain long-term sites, curate datasets, succession plan, and conduct new synthesis using long-term data to understand drivers of change across systems over time.
