We are presenting these maps as a trial. They are very simple for us to produce, we just have to load an xml file to the web server, and use Google Maps to display the data. Google Maps has just provided much better maps of the Channel Islands with much less cloud cover over Guernsey. The satellite picture is much better aligned than is the map; Guernsey is about 200m offset in the display on this web site.
The system is slow when plotting 100s of records. The program works with Internet Explorer Version 6, Netscape 8.0.3.3 and much faster with Mozilla Firefox 1.07and Opera 8.5 but probably not with some other browsers. If you use Internet Explorer to view the maps the Tools/Internet Options/Security/Internet/Custom Level/Reset Custom Settings choice must be set to Medium or lower.
Click on a link below to draw maps for that group. Then click on a species in the list on the left side of the map page to see our records. Species with no records have been recorded from the Channel Islands but perhaps with no distributional data, e.g. the locality is given simply as Guernsey, or we may not yet have entered the record to our database. Click on one of the icons to see the date of the record.
The data given in these maps is a fraction of what we hold. For example for each record shown in these maps we also know the accuracy, the recorder, the identifier, often details of the habitat, the abundance of the species etc. Please contact us for further details.Seaweeds Jan 2007. The Channel Islands are particularly rich in seaweeds. We have extensive records, even of common species, around Guernsey (often Common species are underrepresented compared to Rare ones in our data). The records in the middle of the island are of literature records with no locality data except for "Guernsey".

Ants. Nov. 2007. About 30 species of ants have been recorded from the Channel Islands, many of these have not been found in the U.K. including the very common Lasius emarginatus, a black ant with a yellow middle. Formica pratensis, the common wood ant of the cliffs, is extinct in the U.K. Some of our data sets for ant species are very large with several hundred records. These may take a long time to display.
Dolichopodid Flies Oct. 2005. Dolichopodid flies are often brightly coloured metallic green, some of them have males with peculiar ornaments on their legs. Many are useful indicators of wet land quality. About 85 species have been recorded in Guernsey. Dolichopus signifer breeds in splash zone rock pools and Aphrosylus species are predators of barnacles as larvae so these are found mainly round the coast; many others are found in fresh-water habitats. However, Medetera spp. are found on open surfaces such as rocks and tree trunks and are not particularly associated with water.
