Butterfly recording
Butterfly Conservation, the UK charity dedicated to saving Butterflies, Moths and our environment holds a vast amount of data about butterflies gathered primarily by volunteers. Butterflies for the New Millennium (BNM) was founded when it was realised that the distribution of butterflies had changed substantially since the previous national survey undertaken in the 1970s.

From 1995 to 1999 as part of the BNM, more than 10,000 volunteers resurveyed the whole of Britain with the support of hundreds of organisations, contributing over 1.6 million butterfly sightings. From this data its has been possible to plot changes in species distribution and track changes in the numbers of butterflies. The data shows that butterflies have declined at an alarming rate over recent decades. Some species are showing signs that they are spreading northwards into new areas, possably because of global warming.

New records are essential in order to gauge the extent of these changes over time.
Wider Countryside Survey
A new method was introduced in 2009 as a way of recording butterflies in randomly selected 1km squares. The Wider Countryside Survey is being conducted in association with the British Trust for Ornithology (BTO) to better understand the status of butterflies in the general countryside.
UK Butterfly Monitoring Scheme
The UK Butterfly Monitoring Scheme (UKBMS) records changes in butterfly abundance across a network of over 750 wildlife sites across the UK. Through these sites, the annual abundance of butterflies is determined using data from weekly butterfly transect counts made along fixed routes. At some sites, rare species are monitored by single visit, timed counts.
Submitting your records
The most effective way to make a difference is to send your records to your local branch of Butterfly Conservation. The branch recorder will be able to quickly verify your records and these will become part of the national database.

Ordnance Survey Grid References
In order to provide an effective form of data evaluation of species distribution, ordnance grid references are used in order to pinpoint butterfly sightings to a known resolution (acuracy). The grid reference for any butterfly record should be to a six-figure references which pinpoints a sighting to within a 100m x 100m square.

Distribution maps of butterfly species use data that is plotted in a summary form on distribution maps e.g. as tetrads (2km squares) for local maps, or 10km squares for the national scale maps. Generally atlas organisers seek to ensure that some recording is carried out within each 10km square (often referred to as a tetrad), to give a good level of mapping coverage across Great Britain.
Online OS Grid Reference Generator
Use this interactive online mapping tool to visually find the location and automatically generate a grid reference for you. You can also toggle between aerial photo images and zoom in to accurately pinpoint your sighting within a 10m accuracy.

MapMate tips and tricks
How to change your CUK
When you install MapMate for the first time, the software will ask you for your name, CUK and Serial Number. If you have had a previous installation on the same hard drive/computer, MapMate will assume thet you are the same CUK as the previous installation. Thats fine if your CUK is the same but if you have purchased a new licence, you need to enter your new CUK number. In order to do this, you have to edit the registry on your computer.

WARNING. You should only attempt to do this if you are confident about editing the registry. Removing or editing the wrong registry file can have serious implications on your computer. Please follow these instructions carefully!!

First, you need to uninstall any copies of MapMate you have on your computer.
1. Go to the control panel and choose Add or Remove Programs, select MapMate and click remove.
2. Then go into My Computer, C: Drive, Programme Files and remove the MapMate folder.
3. Empty your Recycle Bin.

Edit the registry (proceed with care!!)
4. Choose the "Run" command from the Windows Start button and type "Regedit" into the command box and click OK.
5. In the Regedit left hand frame, double click on HKEY_CURRENT_USER
6. Double click on 'Software'
7. Double click on 'VB and VBA Program Settings'
8. Click on MapMate and choose Edit > Delete (double check to be sure you have "MapMate" selected before you attempt the Delete command).
9. Close the Regedit window and Restart your computer.
10. Re-install Mapmate using your new CUK.
