Monitoring of halophytic habitats

  

  

During the ante operam (before interventions) monitoring, Researchers from UNIVE-DAIS are mapping emerged  halophytic vegetation (i.e, plants which tollerate salt and temporarily tidal flooding). From April 2018, several sampling campaigns were performed on field, also through an ISPRA drone survey for detailed analysis. Researchers and technicians are now elaborating and digitalizing data to return specific thematic maps.

Monitoring action including these activities is Action D.2, which also focus on the monitoring of halophytic habitats located in the saltmarshes surrounding the freshwater input and reedbed transplantation sites. The  aim is to evaluate the variation on halophytic habitats distribution induced by the project interventions. Indeed, Scientists will perform the same activities at the end of the interventions for comparing purpose.

Monitoring of the Habitat (1150*) Coastal lagoon before conservation actions

  

  

From November 2017 to October 2018 the Monitoring of the Habitat Coastal lagoon took place in the project area, with the aim of defining the initial environmental status before interventions.

The activities, carried out within the Action D.1 included the execution of measures, sampling and analysis of different components such as water, sediment and biological communities.

Once a month, ISPRA and UNIVE-DAIS sampled water and settled particulate sediments to characterize salinity, temperature and the quality of the water column and granulometry, sedimentation rates, nutrients, carbon, and general parameters of sediments.

Sediment parameters and biotic component, with particular reference to the Biological Quality Elements (BQE) Macrophytes (macroalgae and seagrasses), Macrozoobenthos and Fish fauna, were sampled twice a year, on Spring and Autumn, by UNIVE-DAIS and ISPRA.

Finally UNIVE-DAIS mapped seagrass all around the project area. These data will be useful to estimate the transplant success by comparing states before and after the project implemetation.

ISPRA and IPROS also performed specific sampling campaigns with particular reference to salinity measures (Action A.2). Bathymetric surveys, with the aim to estimate morphological variability of shallow tidal flat induced by the project, were performed by IPROS and OOPP (Action A.2).

Researchers and technicians are now hard working to elaborate all data. Results will be soon available on the first Monitoring Report of the project!

 

Monitoring of Avifauna continues

Marangone minore (Microcarbo pygmeus, PALLAS, 1773

Pygmy Cormorant (Microcarbo pygmeus, Pallas, 1773)

As expected by the monitoring actions of Life LAGOON REFRESH project, monthly bird sightings are taking place along Sile river and the Lagoon. Here you are a picture of one of the target species of the Project, the Pygmy Cormorant, the smallest cormorants in the Venice Lagoon. Relative of the Cormorant and Shag, it is a species that falls within the highest European and Italian protections. In the Venice lagoon it is very common and breeds in colony  as in the whole upper Adriatic.
