Regional network

Marine non-indigenous species (NIS)

ALIEN-Mer Normandie

Launched on the initiative of Les Amis de BioObs and Association Nature du Calvados within the Sentinelles de la Mer Normandie network, the ALIEN Mer Normandie programme monitors, with the help of citizens, non-indigenous species and species extending their range in Normandy’s waters and on its foreshores.

Coordination: URCPIE de Normandie, with the expertise of the OFB and UMS PatriNat

The ALIEN-Mer Normandie species leaflet

All the species of the network in a printable document, to take diving or along the shore: photo, name, group, number of observations in the network and tick boxes.

Species to report

Two complementary approaches: on foot along the shore and the strandline, or underwater — scuba diving, snorkelling and freediving.

Showing 23 species (of 23)

How do I take part?

  1. I observe

    While scuba diving, snorkelling, freediving or on foot along the shore and the strandline.

  2. I take a photo

    A photo, even an imperfect one, lets the validator confirm the identification.

  3. I record my survey

    In my BioObs logbook: species, habitat, date and place.

  4. The data travels on

    Once validated, it is added to the ODIN database, the regional platform of Normandy’s nature and landscape information system (SINP).

The spirit of the network

Better understanding potentially invasive species and controlling their spread: this is the goal BioObs works towards alongside its regional partners.
