A New Calder center greenhouse with automatic irrigation and lighting systems

An automatic irrigation and lighting system was recently installed in the newest Calder greenhouse, itself just three years old. The irrigation component consists of both sprinklers and misters that permit researchers to water plants at specific times of day and night much more efficiently than when someone had to be on site to do the work manually. In addition, the three separate zones for lighting allow different growing regimes to be set up simultaneously, providing increased flexibility for users.

water quality monitoring - a newly-deployed calder lake buoy/sonde

Long term water quality monitoring has been re-initiated at Calder. Until about 2004, staff and students had been monitoring water quality in the 10-acre meso-eutrophic temperate lake each month by manually taking measurements of temperature, oxygen, pH, chlorophyll a and nutrients (nitrogen and phosphorus). The hope of resuming this monitoring program was realized in 2013 with the purchase of a self-contained monitoring buoy that collects data on these variables: temperature, oxygen, pH, conductivity, chlorophyll a, and turbidity and relays that information to a data logger set on land. The Calder Center is now able to share a link to the real-time data via Fordham's website.

Long term vegetation monitoring

The Calder Center has restarted long term monitoring of the diversity, abundance, and size of its forest trees. During the summer of 2013, a Fordham undergraduate biology student, using locations from a previous ecology study (by Dr. Jim Lewis), marked, measured, and mapped tree species in 25 woodland plots at the Center. Additional plots in Calder's fields and wetland areas will be established this coming summer. Besides plants, the diversity of invertebrates will be included in future surveys.

Camera Trap at Calder

Coyotes, a bobcat and bear - Oh My! With more sightings of these animals in recent years (< 5 years), Dr. Jason Munshi-South has installed a camera trap at the Calder Center. Choosing an out-of-the-way site on the property was not a problem and that very seclusion has led to visits by some seldom seen residents. The Reconyx 500 camera has so far "captured" coyotes, white-tailed deer, foxes, opossums and turkey vultures. Before long, these images will be available on our website for all to see. Given our initial success, plans are underway to install another one at the station in the near future.
