Developed by Central Borders Red Squirrel Network, this App displays sightings of Red Squirrel, Grey Squirrel and Pine Marten from the year 2000 to the latest full year for which data is available.
All data sourced from NBN Atlas, including the following sources:
- Non-avian taxa (BTO+partners)
- MammalWeb records
- The Scottish Squirrel Database
- National Mammal Atlas Project, online recording
- Vincent Wildlife Trust
Usage Guide
- The App is designed for use in Web browsers. The device must have an Internet connection to load background mapping and species data. However, the data has already been downloaded from NBN Atlas and is not reliant on that system during operation.
- When the App is opened, it displays sightings for the latest full year. The shade of the circles indicates density: Darker circles mean higher sightings density per square km.
- Use your mouse scroll wheel and click-and-drag to navigate around the map.
- Select a circle to view individual sightings. Zoom in for precision. Use the “Info” icon to toggle labels for the date of sightings and quantity.
- Select the species or year in the sidebar to change the current view.
- Select the “Map Scale” to toggle between “County level”, “Red Squirrel Forum for South Scotland” groups, “MISC” (any groups not in the previous two categories), “HEC” – which show species counts and density in 10km hectads (squares) and “HEX”, which shows density in hexagons, which are dynamic and change with the zoom level.
- Click any of the circles or hectads to zoom into that area and show individual sightings.
- Background mapping can be selected and includes: Street-level, topographic and satellite imagery.
- The “ALL” (four-corners) icon zooms out to the full extent of the current category.
- The “Timer” button cycles through the years. If a region is selected, it cycles sightings for that region and narrates the data. With sound switched on it will read out the results.
- The graph icon calculates the species trends for the selected area form 2000 through to the latest full year of sightings. The graph can be a line or a bar graph.
- The Download icon will generate a PDF file containing sightings trends for all areas – warning – this will take several minutes to perform, so please do not interrupt part-way through.
