- Abstract
- Selection frequency of planning units in the “connectivity with 20 days PLD” scenario of the ATLAS basin-scale systematic conservation planning exercise (D3.4), aiming to identify conservation priority areas for the deep-sea biodiversity. The selection frequency reflects how often the 25km * 25km units were selected within the 30 solutions of the scenario, from 0 for units that were never selected, to 30 for systematically selected units. This work is exposed in ATLAS Deliverable 3.4: “Conservation Management Issues in ATLAS. Basin-scale systematic conservation planning: identifying suitable networks for VMEs protection”.

- Purpose
- The basin-scale systematic conservation planning in ATLAS aimed to inform Marine Spatial Planning and conservation initiatives for the deep sea of the North Atlantic, by identifying conservation priority areas for the Vulnerable Marine Ecosystems (VMEs) and deep fish species and discussing the efficiency of the current spatial management context relatively to conservation stakes. This work is exposed in ATLAS Deliverable 3.4 : “Conservation Management Issues in ATLAS. Basin-scale systematic cons

- Conservation scenarios were implemented using the R package Prioritizr, on a gridded area representing the North Atlantic (18°N to 76°N and 36°E to 98°W) from 0 to 3500m depth, divided in 25km * 25km planning units. Spatial prioritisation and mapping were done on an Albers equal-area conic projection centered on the Atlantic ocean (latitude 30°N; longitude 30°W). A wide range of datasets displaying the distribution of species and habitats, human activities and current spatial management was integrated to conservation scenarios. Connectivity data was obtained from a Langrangian particle tracking model, implemented for hypothetical benthic larvae with a 20 days pelagic larval duration (PLD) and an 80 days PLD. Connectivity scenarios were implemented on a smaller study area than others, matching with the extent of the VIKING20 ocean circulation model used to produce connectivity data (30°N to 85°N and 81°W to 21°E in the Arctic and to 8°E in the Mediterranean). The “connectivity with 20 days PLD” scenario targets VME-indicator benthic species (cold-water corals and sponge) as well as deep-water fish species, and habitat (VMEs, VME-supporting geomorphological structures) features, while replicating the conservation objectives in the different regions of the ocean basin, favouring a connected conservation network based on the modelled dispersal of 20 days PLD benthic larvae, and considering an area-based cost. The conservation problem was solved 30 times and the 11 solutions that were achieved before the solving time limit were selected to evaluate the selection frequency of planning units.
