Set in the Arboretum’s Conifer Collection, it will feature music, dance, sculpture, spoken word, and the signature MassQ face painting art form.
2025 Research Awards
Our 2025 research awards support diverse and groundbreaking studies across plant and climate science—from pollinator behavior to drought resilience to underground fungal networks. These projects, made possible by the Arboretum’s world-class resources and donor support, highlight the critical role of the Arboretum and our community in advancing scholarship and educating the next generation of scientists.

Professor Benton Taylor Named Fellow of the Ecological Society of America
Benton is an ecosystem ecologist working to understand how terrestrial ecosystems will respond to global change, and what the consequences will be for future carbon cycling. His work spans from tropical rainforests to the arctic tundra, focusing primarily on how plant-microbial partnerships impact ecosystem responses to rising carbon dioxide levels, warming, drought, severe weather, nutrient pollution and human land use.
