The Environmental Monitoring and Management Alliance (EMMA)
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.
For more information about EMMA, please visit our website: http://www.emmahv.org/
Founded in 2013 by Teatown Lake Reservation, EMMA is a regional network of land managers and researchers committed to developing standardized methodologies for environmentally relevant research and data collection.
EMMA is composed of 10 member organizations including:
Cary Institute of Ecosystem Studies (http://www.caryinstitute.org/)
Huyck Preserve and Biological Field Station (http://www.communitygreenways.org/)
Louis Calder Center (http://www.communitygreenways.org/)
Mianus River Gorge (http://www.mianus.org/)
Mohonk Preserve (http://www.mohonkpreserve.org/)
New York Botanical Garden (http://www.nybg.org/)
Teatown Lake Reservation (http://www.teatown.org/)
Vassar College’s Vassar Farm and Ecological Preserve (http://farm.vassar.edu/)
Ward Pound Ridge Reservation (http://parks.westchestergov.com/ward-pound-ridge-reservation)
EMMA has four priority issues that guide its monitoring projects: climate change, habitat loss and fragmentation, invasive species and deer overabundance.
EMMA currently has four ongoing monitoring projects.
Deer Exclosures – In order to assess the impacts of deer on forest regeneration, EMMA is monitoring plots that are inclusive and exclusive of deer. Plots are censused every 5 years at 8 of the 10 sites.
Phenology Trails - Phenology is the study of the timing of life cycle events, such as when birds migrate or when flowers bloom. Long-term monitoring of plant phenology will allow EMMA to assess the effects of climate change on our habitats and native flora. Each of the 10 EMMA sites monitor a variety of native plant species. Data are submitted to the USA National Phenology Network, a nation-wide citizen science program. To download our phenology data, please visit:

Weather Stations – To monitor climate change and to provide background data for EMMA and other research projects, weather stations are located at 8 of the 10 sites. Several sites have more than one weather station and some weather stations have long-term data. To access weather data:
- EMMA Weather Station Data - Cary Institute of Ecosystem Studies
- EMMA Weather Station Data - Vassar Farm and Ecological Preserve at Collins Field Station
- EMMA Weather Station Data - Mohonk Preserve
- EMMA Weather Station Data - Louis Calder Center
- EMMA Weather Station Data - Huyck Preserve
- EMMA Weather Station Data - New York Botanical Garden
- EMMA Weather Station Data - Teatown Lake Reservation
- EMMA Weather Station Data - Ward Pound Ridge Reservation
Camera Traps – Camera trap surveys of game animals will be conducted to gather better estimates of the diversity, presence, and abundance of large mammals within the EMMA network. Camera traps will be deployed by the end of 2016.
