Measuring Biodiversity on a Green Roof

1 minute read

In March of 2024, PROJAR together with students from EFA La Malvesia started the implementation of a green roof at PAIMED headquarters. This is a 1 to 1 case action within the framework of the BARCOVE project "Building an Applied Research facility into COVE".

This pilot case involves an applied innovation collaboration between the company and the VET center. Students participating in the project, will learn from professionals not only how to install a green roof but also how to carry out a monitoring and impact evaluation plan.

Evaluating different plant species

The target of this experience is to check the biodiversity level that a green roof can bring into an urban area. In order to get started with the research, the rooftop has been divided into two different parts with a total area of 100m2. In half of it, a large variety of shrubs has been planted with the aim to attract as much biodiversity as possible together with a small pond. In the other half of the rooftop, a grass turf of zoysia trinity has been proposed, a new variety that claims to be draught resistant and low maintenance. By implementing this setting, it will be possible to evaluate the difference that plant species bring in terms of biodiversity.

Biodiversity sensor

For this study and monitoring, a biodiversity sensor has been installed, developed by the Dutch company FaunaPhotonics. This technology detects disturbances caused by insects in flight, will be installed to obtain the necessary data for the case. Moreover, and in order to monitor water consumption,  a rain gauge has been implemented, humidity and temperature sensors.
