PADDDtracker.org Technical Guide Version 2 updates prior technical guidance. It outlines a standardized process to collect data on protected area downgrading, downsizing, and degazettement (PADDD) events - legal changes that temper restrictions within, reduce boundaries of, or eliminate protected areas. The guide is intended for researchers and practitioners who are interested in investigating historical and/or current PADDD events in any country. To date, this guidance has been applied to document PADDD in more than 70 countries, supporting evidence published in at least 10 peer-reviewed publications and informing dozens more. Peer-reviewed data of PADDD events are available for download on PADDDtracker.org.
