Heidi Zimmer

Dr. Heidi Zimmer is a Researcher in Botany at the Commonwealth Scientific and Industrial Research Organisation (CSIRO), working within the Orchid Research Program at the Centre for Australian National Biodiversity Research. She serves as Regional Coordinator for the IUCN Orchid Red List Authority for Australasia and specializes in threatened plant conservation, with particular expertise in Orchidaceae and Araucariaceae.

Her academic qualifications include:

• PhD, University of Melbourne, 2016 (Wollemi pine ecology and conservation)
• Master of Forest Ecosystem Science, University of Melbourne, 2010 (Papua New Guinea montane forests)
• Bachelor of Environmental Science, Monash University, 2006

Dr. Zimmer's research integrates evidence-based taxonomy, extinction risk assessment, and ecological field studies to develop practical conservation frameworks for critically endangered flora. Her work emphasizes how accurate species delimitation directly informs effective protection strategies, particularly for orchids facing habitat loss and climate threats. She pioneers ex situ conservation techniques including horticultural translocation and community-based propagation programs, while investigating ecosystem recovery post-disturbance events like wildfires and invasive pathogens.

Analysis of her 2022-2025 publications reveals three dominant research strands: (1) description of new orchid species using integrative taxonomy, (2) development of conservation translocation protocols for Wollemi pine, and (3) assessment of emerging threats like myrtle rust on epiphytic orchids. Her work consistently bridges molecular systematics with on-ground conservation management, demonstrating how phylogenomic insights directly inform IUCN Red List assessments and recovery planning.

Her conservation leadership has been recognized through:

• NSW Minister's Award for Energy and Environment (2020) for Wollemi Pine Protection Operation
• NSW Premier's Award Finalist (2020) for same operation

Dr. Zimmer actively shapes conservation policy through her IUCN Red List Authority role and previously served as Editor of Australasian Plant Conservation (2017-2022). Her collaborative projects involve government agencies (NSW Department of Planning, Industry and Environment), botanic gardens, and international partners to implement monitoring frameworks for threatened species translocations and develop evidence-based conservation guidelines.

She leads CSIRO's Orchid Research Program, which focuses on Australasian orchid systematics, extinction risk assessment, and conservation translocation science. The program maintains close collaboration with the Australian National Herbarium and international conservation networks to advance threatened species recovery through integrated taxonomic and ecological approaches.
