The MOU with Alberta is deeply disappointing. It sacrifices climate policies, places too many eggs in the industrial pricing basket, proposes a pipeline deal that would increase emissions, and would have Canada double-down on fossil fuels at a time the world is moving towards clean energy.

Our lab launched a logo contest led by our amazing students and professionals. Loved seeing everyone’s creativity …it’s going to be a tough pick! #teamspirit

Urban nature based solutions are critical - but often hampered by a lack of collaboration across sectors. How can we do better?

This was such a rewarding project to lead, alongside great colleagues from @environmentca.bsky.social, @treecanada.bsky.social, and many many others.

Boston’s Food Forests Take Root as a Climate Equity Strategy - Inside Climate News A decade of organizing has turned trash-strewn lots into edible parks. Now Boston is expanding food forests as part of its climate action plan.

🌱 Boston is turning vacant lots into edible forests, integrating food, nature, and community right into the city fabric. Urban climate justice in action. Shout out to @mayorwu.boston.gov for all of her great work! 🍓🌳

Very cool initiative training citizens/residents in tree pruning & stewardship 🌳 Wonder if something like this will catch on here in Canada 🇨🇦

Field trip day! 🌳 Our Urban Forestry course is out in the field …Dominic, a master’s student in the lab, is leading a session on #tree plantation pits at our living lab site, where we’re testing 9 structural pit designs with the city. #UrbanForestry #FieldLearning #urbanforests

Infographic detailing seven ways to create a bird-friendly community, including planting native plants, turning off lights, avoiding pesticides, and preventing collisions.

Urban expansion can lead to habitat loss. Yet, as IPBES #GlobalAssessment shows, smart city planning + nature-based solutions can create resilient, bird-friendly cities.🌍

This #WorldMigratoryBirdDay, let’s protect migratory birds in our #SharedSpaces 🏡

Savannah Bissegger O’Connor, Dominic Bartolacci et Ravosoa Ramaroson de la Chaire de recherche sur l’arbre urbain et son milieu présenteront leurs travaux au Rendez-vous #arboricole 🌳
