Spring Member Meeting 2021 Data Updates and Hotline FAQ

This reunion took place June 3, 2021. It was another virtual event to review TreeSnap trends, briefing on expanding data collection to iNaturalist, and opportunities for collaboration and research as well as FAQ from the "madrone hotline."

Pacific madrone: sacred, emergent, adaptive.

A Tacoma Tree Foundation Growing Skills Webinar was January 28, 2020. Watch it on the TTF YouTube Channel

The ARME shares the interspecies love story we share with madrones. Celebrate this sacred and iconic tree and its cultural importance. Madrone forests refuge complex interactions and patterns, biodiversity belowground and in the tree canopy. Meanwhile, the species safeguards adaptive capacity amidst climate disruption. We highlight the relationship we have with madrone while also building the skills required to help ensure we have a future for the species.

About the Presenters

Jarmila PItterman is an Associate Professor in the Department of Ecology and Evolutionary Biology at UC Santa Cruz. She presented findings from her team's studies on madrone water stress during extended drought in California and published in the article "Two coastal Pacific evergreens, Arbutus menziesii, Pursh. and Quercus agrifolia, Née show little water stress during California's exceptional drought."

Renata Poulton Kamakura is a current PhD student in ecology at Duke University studying urban forests. She presented her research looking at growth and disease of madrones in the Common Garden Study.

Janneke Peterson has experience in both outdoor science education, as a classroom middle school science teacher and curriculum developer. She told us about supporting curriculum in schools focused on growing madrone seeds and teaching photosynthesis.

Michael Yadrick is a Certified Ecological Restoration Practitioner supporting Seattle Parks and Recreation and Green Seattle Partnership. He presented an update about Seattle's Madrone Recovery Project in Seattle's forested parkland.
