EASIN Species Search and Mapping User Guide


Introduction

This is a brief user's guide to the EASIN Species Search and Mapping new tools. From the EASIN internet site, Menu/Services/Species Search and Mapping, the User accesses the introductory page:

[Introductory Page]

A Submenu appears showing four items:

The User can start with ‘Species Search’ to search for species or open the map directly from ‘Species Mapper’ and use the map controls to select and map species.


Species Search page

This page has three collapsible sections (“Select filters”, “Taxonomy”, “Pathways”) to select searching criteria.


Select filters section

The User can select any combination of the following criteria:

  • Impact: the impact can be High or Unspecified
  • Is Of MS Concern: species who are of concern to at least one EU Member State (EU Regulation 1143/2014)
  • Is Of EU Concern: species in the EU list of invasive alien species of Union Concern (EU Regulation 1143/2014)
  • Partly Native: species being native in at least one EU Member State
  • Species Status:
    • Alien: art. 3 EU Reg.
    • Cryptogenic
    • Questionable
  • Environment:
    • Terrestrial
    • Freshwater
    • Marine
    • Oligohaline/Estuarian
  • Species Name: the user can type the species name or part of it to search for specific species or groups of species.

Figure 1 displays the first (from top) section.

intro page

[Figure 1: species search criteria]

Please note that this section includes three options slider buttons on the left and two options slider buttons on the right. The User can set the buttons on the left to NO|OFF|YES while the two on the right can be set to OFF|ON.

In both cases, by leaving the filters to OFF, the search function would skip the corresponding values, while with ON (or YES) or NO the search function collects only species according to the selected options.

The species scientific names, synonyms and common names can be used to search for species in the ‘Search name’ field. By typing at least three characters a drop-down list appears containing species compatible with the typed term. A species (one) can be selected from the drop-down list, or the User can search and select species containing just the typed part.

The above Figure 1 shows the following scenario:

  • Alien set to ON, means the search will collect alien species, excluding cryptogenic and questionable species.
  • EU Concern set to YES, means the search will collect species of EU Concern only.
  • Partly Native set to NO, means the search will select only species alien to the whole Europe.
  • The User is looking for species whose name contains the term ‘callo’.

The searching criteria are aggregated by logical ‘AND’ operators, so if the User has selected the above example filters, the criteria would select alien species and EU concern species and not-partly native species whose name include the ‘callo’ term.


Taxonomies section

A hierarchical tree view is displayed in this section. The tree view is populated by aggregating the taxonomies from the species in EASIN Catalogue. The User can select any number of taxa or single taxon, and full taxa nodes. The taxonomy tree is populated while the User expands the nodes.

Figure 2 displays this section (and the previous section is collapsed).

intro page

[Figure 2: taxonomy criteria]

The selected taxa would be aggregated to the rest of the criteria by following the logic explained in the first section. In Figure 2 the whole Nematoda node is selected.


Pathways section

In this section the User can choose between “Hulme Pathways” (modified from Hulme et al. 2008; http://dx.doi.org/10.1111/j.1365-2664.2007.01442.x) or “CBD Pathways” (CBD 2014. UNEP/CBD/SBSTTA/18/9/Add.1) categorization by using the slider in Figure 3. By switching the pathways types, the selected pathways are reset.

The selected pathways will be aggregated to the rest of the criteria by following the logic explained in the first section. In Figure 3 the “Release in nature” CBD Pathway is selected.

Species Search result

After clicking on the Search Species button, the search function will search for species combining the selected criteria from the three sections explained above.

Figure 4 shows the search results, in this case all the Marine species from the Catalogue were selected for search, and all the species in the first results page are selected to be mapped.

Species Factsheet

From the Species Search results, every single species name, or the plus [+] icon close to it, is clickable to expand the species factsheet. Figure 5 shows an expanded factsheet area .

Species Mapper

From the Species Search results the User has the option to select specific species and click on [Map Selected Species] to map those species or simply choose [Map Found Species] to map all the species from the search results. In the following Figures, all marine species where searched and mapped.

Working with the Species Mapper

On the left hand the User can interact with the map by four control buttons:

  • [Magnifier button] Search for a new set of species to map
  • [Double clock button] Specify the year range to refer to a specific period, default is 1500 – today.
  • [Printer button] Export a PDF containing the map, the legend and information regarding the map itself.
  • [Down arrow button] Download the current layer in GeoJSON or WKT format.

Searching Species from the Species Mapper

By clicking the [Magnifier button] the user opens a modal (pop-up) panel control which shows an interface like the search page. Please refer to the Search page above section for details.


Selecting Specific Data Partners

Click on the [Funnel] button to display map filters panel and use the toggle buttons to turn your options ON or OFF, green means ON, yellow means OFF.

[Figure 9: map filters]


Mapping the native range on a single species

If ON is selected, the native range option makes a double layer visible for single species only. In Figure 10 the map displays the native and alien range layers for Abramis brama. This functionality is available only when one specific species is selected.

Selecting specific time range

The User can specify the species occurrences by time range clicking the [double clock] control button on the map, which opens the time slider control panel as shown in the Figure 10.

Exporting a PDF

The user can export the map in the form of a PDF document containing the map (the current visualized map at the moment of the click) and a summary with map data. Figure 12 shows the PDF preview after clicking on the [Printer button].

intro page

[Figure 12: PDF export preview]


Map layer download

The map layers can be downloaded in both GeoJSON and WKT formats. Please note that the coordinate reference system in the GeoJSON is WGS:84, the only officially supported by the GeoJSON standard. The WKT files are generated using the EPSG:3035 (ETRS 89) coordinate reference system used in the online map.

To download the layer, the user must click on the [download button] and select the wanted format from the opening panel. Figure 13 shows the download options.

[Figure 13: layer download options]


Exploring mapped species per area

After having mapped the selected species, by clicking on the map a small pop-up opens to show the total number of species mapped in the clicked area. By clicking the species number, a second dialog opens to show the list of original occurrences and the related data partners. If the URL of the original occurrence is provided, its description is also a link to it. Please refer to the following Figure 14 and 15.
