Developing a Regionally-Coordinated Ecological Monitoring Network in New York's Hudson Valley

The Environmental Monitoring and Management Alliance (EMMA)

Our Work

EMMA’s member organizations investigate the Northeast US’s major conservation concerns on a regional scale through collective research and long-term monitoring.


A growing repository of educational resources and lesson plans that can be used to teach people of all ages about the Hudson Valley’s natural history and the importance of conservation.

Get Involved

Join a vibrant and connected community of resource managers, researchers, educators, and concerned citizens who work together to protect the environment.

The Environmental Monitoring and Management Alliance brings together organizations and individuals centered in New York’s Hudson Valley to develop a regionally-coordinated ecological monitoring network that informs sustainable management practices and natural resource conservation through scientific research while engaging the public in environmental protection.

EMMA’s core member organizations recognize climate change, invasive species, habitat loss and fragmentation, and deer overabundance as urgent threats to ecosystem health in the Hudson Valley region. We aim to address these threats through impactful, regional coordination that facilitates implementation of natural resource management solutions. 

Our Member Organizations

EMMA was founded by Teatown Lake Reservation to collaboratively address regional ecological threats through a grant from the Land Trust Alliance in 2013 . The core member organizations below came together to support this effort, forming what is now known as EMMA. In 2015 Vassar College received a grant from the Leona M. and Harry B. Helmsley Charitable Trust that, in part, funded a coordinator position and a post-baccalaureate fellow position.
