New sites

If you have been allocated a new site you will receive a few six figure grid references to choose from.

You will get a choice of between two and six survey sites within 10km of your address. Select the site nearest to you and most accessible to you.

You will then need to go and find a map of your site to photocopy or print out.

New site maps

The Ordnance Survey (OS) range of maps can be purchased from bookshops or direct from the web. Alternatively, you can usually make copies from the maps held in your local library. If you have a local Biological Records Centre they may hold local maps and allow you to make a copy from there.

The relevant OS map series are:

• The 'Explorer' series covering most of the country at a scale of 1:25,000. (The remaining areas are covered by the old 'Pathfinder' series)

• The 'Landranger' series covering the whole country at a scale of 1:50,000.

For this survey a 1:25,000 scale is ideal as you can see landscape features in detail.

Online map services

Multimap

• On the Multimap website you can search on your 6 figure grid ref and it will display a map divided into 1km grid squares with your grid ref marked by a circle

• The default "Map" view will display street names which can be helpful for finding your way to the survey site

• Click on "OS Map" to view the Ordnance Survey map which will show landscape features in more detail

• Zoom in until you can see the maximum detail but make sure you can see a complete 1km square as this will give you a sense of scale and help you mark out a route 1km in length

Streetmap

• On the Streetmap website you can search on your 6 figure grid ref and this will be marked with an arrow on the displayed map.

• When fully zoomed in, the map will be displayed divided into 0.5km grid squares with street names shown which can be useful for finding your way to the survey site. However, very few landscape features are shown at this scale.

• Zoom out until you can see the Ordnance Survey map which is divided into 1km squares with landscape features shown in detail.

• Make sure you can see a complete 1km grid square as this will give a sense of scale and help you mark out a 1km route.
