What an honor to welcome everyone and introduce both Onondaga Faith keeper Oren Lyons and UB President Satish Tripanthi in Buffalo at last night’s opening of the Conservancy’s Voice, Choice & Action global gathering on working with Indigenous partners. – at Manhattan, NY
Great hike yesterday with colleagues at Lisha Kill Preserve near Albany. It is one of the Conservancy’s most visited preserves nationally, with over 30k visitors annually. A beautiful and special place that’s just out the back door.
Neighbors got together this weekend to plant flowers in our tree beds. Reminds us to take care of the trees that take care of us. #urbanforest #citytrees
It was so great to (re)connect with Conservancy colleagues in the Santo Domingo office today. I am excited and impressed with their leadership on climate change and the role nature plays in all our lives — in one of my favorite countries in the world! – at Santo Domingo, Dominican Republic
This is a truly remarkable and important accomplishment for all New Yorkers — current and future! New York continues to help lead the nation on climate and conservation solutions that give us hope and remind us of the difference we can make.

ALT Text reads We Passed Prop 1. Thank you, New Yorkers, for delivering for clean water and air. There is a large check mark in green next to the text.

Great explainer piece from @OstapiukJ in @siadvance on what the #NYBondAct is and why so many of us are rallying in support of it. Read, and then go vote! bit.ly/3EbtENj
Me when someone mentions climate change without mentioning how communities who are least responsible are disproportionally affected.
We need to better appreciate our carbon “shadows,” which help us understand broadly how our choices affect climate change, and push industry to better tackle climate change – through regulations, consumer choices and corporate responsbility. bloomberg.com/news/articles/…

Nature has been telling us for years that🌏is in trouble. This is just another stark reminder. At #COP27 and #COP15 it is time for world leaders to act. I am optimistic that when we come together, we will find a way for adaptation, finance, and nature. unep.org/resources/emissions…
Wonderful evening at @weact4ej gala, including celebrating @tnc_ny colleague and honoree @jessicaottney. Amazing organization and great people!
Huge step! Appreciation to California. Indigenous knowledge and stewardship is vital to conservation success. Would love to see initiatives like this happen everywhere, especially right here in NY. apnews.com/article/californi…
Wonderful to see the @NYDailyNews endorsing the Clean Water, Clean Air & Green Jobs Bond Act. Vote yes! @NYBondAct nydailynews.com/opinion/ny-e…
Vote yes on Prop1! So we can have more Gowanus rain gardens. @NYBondAct
So energizing to see so many faces in our NYC office today for our Day Of Gathering happening at offices all across New York! I am so proud of and appreciative of the NY team!

Thrilled to see @NYCMayor Eric Adams excited about #CityofForestDay2022 happening this Saturday! Thanks for your leadership, Mayor Adams, to encourage NYers to celebrate and care for the #UrbanForest! forestforall.nyc/city-of-for…
Trees and open spaces aren't luxuries, they're necessities in NYC.
Join us this weekend for our inaugural City of Forest Day. There are 50+ events planned across our city to celebrate our urban forests and recognize the groups taking care of them.
