Ecology of Plants in Communities Lab

Research Facility

Ecology of Plants in Communities Lab
Saint Mary's University
Nova Scotia (NS)

Research in plant ecology: coastal barrens, urban ecology, green roofs, green infrastructure. The green roof research facility allows for quantification of ecosystem services and economic benefits of green roofs including reduction of building energy costs, contributions to stormwater management, provision of biodiversity habitat and carbon storage.

Equipment 3 piece(s)

Portable Photosynthesis unit
CID Biosystems

Quantify photosynthetic rate, transpiration rate, stomatal conductance. Has CO2 control module and chlorophyll fluorescence units also. Will be purchasing light control module.

Compare photosynthetic rates and water relations between plants species used in green roof projects.


Green roof monitoring system (instruments, dataloggers)
Campbell Scientific

Quantify soil heat flux, soil temperature, moisture in green roof systems. Allows for long-term monitoring. We have several CR1000 dataloggers installed in permanent locations on two green roofs. We also have a full weather station on one of the roofs (pyranometer, anemometer, tipping bucket rain gauge etc.)

Campbell scientific: heat flux plates (28 on roof 1, 8 on roof 2); thermocouple temperature probes (54 on roof 1, 20 on roof 2)


Green roof stormwater flow monitoring system
Campbell Scientific
TE 525

 12 1m x 1m green roof cells (two are conventional roof controls) each outfitted with drainage pipe underneath connected to tipping bucket rain gauges to monitor flow rate of roof runoff. Green roof cells have been planted with various plant combinations and substrates over the years.

Second roof has 8 x 6m x 4.5m green roof cells planted with a variety of native plant species (approx. 7.5 cm substrate depth), each hydrologically separated and draining through pipes to paddlewheel flowmeters below (Blue White Industries F-2000).

Possibility to sample water quality in each facility (not yet tried)
