1. Using QGIS for Ecological Surveying Andrew Whitelee, Senior Ecologist (@verdantwildlife) Taylor Wildlife www.taylorwildlife.co.uk 6th QGIS UK User Group Meeting, Edinburgh, Scotland
2. Who are we and what do we do? • Ecological Consultancy based near Aberlour • Specialists in upland and island ecology • Plants and habitats • Birds • Butterflies • Mammals
3. What we use QGIS for • Creating Habitat Maps • Mapping and Recording Habitat Plots • Creating “blank” survey sheets • Deer Management Plans • Presenting results of • Butterfly Surveys • Mammal Surveys • Bird Surveys
4. Habitat Mapping
6. Habitat Plots – Grazing Impact Analysis • Each site has 60 habitat plots, consisting of 2 x 30 plots of the two dominant habitats • Each plot is 2m x 2m and has to be surveyed once a year for 5 years • Marked with a wooden stake and a 10 figure grid reference • Plotted on GIS as points
9. Butterfly Surveys • Survey each 1km square 3 times, at least 10 days apart • Survey carried out by means of 2 x 1km parallel transects through the square
10. • Report requires us to establish presence of species per km square • Use TomBio plug-in to represent the results
11. Survey Sheets • In the summer we can have up to 20 seasonal field surveyors spread across at least 5 sites • Important to standardise the surveying so that all surveys by all surveyors across all sites are comparable • To facilitate this we use the QGIS Atlas Tool to create standard survey sheets, dividing sites into 4km2
12. • Standard Recording Sheet • Name, Date, Survey Type • Grid References • Km squares divided into four
13. Bird Surveys • Survey Method • Each 1km square is divided into 4 x 500m squares • Required to cover all the ground in each 500m square in 20 to 25 minutes, going within 100m of each point in the square • Time entering and exiting the square, route taken and birds seen and their activity needs to be recorded
15. Routes Tried using GPS track to plot routes, however we found entering them manually was easier
17. Time for a demo…………

23. Summary • Quite new to QGIS and haven’t fully exploited its potential • Knowing how QGIS works means we can tailor our fieldwork to make sure we collect and record the correct data • Excellent tool for presenting our data (with lots of help from Amy at Cawdor Forestry)
