Regional Partners

Land and Stewardship

The Mianus River Gorge is a founding partner of the Hudson to Housatonic (H2H) Regional Conservation Partnership, which began as an initiative in 2014 and took its present form in 2016.  H2H is an interstate collaboration of conservation organizations and municipal partners across Fairfield County in Connecticut and Westchester, Putnam, and a portion of southeast Duchess Counties in New York State. The mission of the H2H is to work across CT and NY to improve water quality and promote conservation and sound stewardship for the health of people, plants, and wildlife.  To learn more, go to:

Mianus River Gorge is a key partner of the Lower Hudson PRISM (Partnerships for Regional Invasive Species Management). The Lower Hudson PRISM is one of eight regional partnerships in the state of New York that coordinate on, share best practices for, and fund invasive species monitoring and control throughout their respective areas of operation. PRISMs are funded by the Department of Environmental Conservation through the Environmental Protection Fund and hosted by a non-profit organization. The Lower Hudson PRISM has been hosted by the New York – New Jersey Trail Conference since 2013. To learn more, go to:


The Mianus River Gorge is a founding member of The Environmental Monitoring and Management Alliance (EMMA), formed at Teatown Lake Reservation in 2013.  EMMA consists of member organizations dedicated to research, education, ecological and environmental science and conservation of the natural areas that make up their preserves within the greater Hudson Valley region. The collective research experience of EMMA’s member organizations allows us to investigate the Northeast US’s major conservation concerns on a regional scale. Geographic variability across member sites provides EMMA with the flexibility to both monitor current and emerging conservation threats and test multiple land management strategies to find the best solutions for reducing or eliminating those threats.  To learn more, go to:

The Gotham Coyote Project, of which MRG is a founding partner, is an ongoing effort to study the ecology, population growth, and range expansion of eastern coyotes (Canis latrans) in New York City.  Since 2010, we have employed camera traps (motion-activated cameras placed on trees that photograph passing wildlife) to survey NYC parks for the presence of coyotes.
