About us

The purpose of the GBRC is the collection, management and interpretation of wildlife data to support the conservation, understanding and enjoyment of local biodiversity.

The GBRC gathers verified species records (over 100,000 records of 11,000+ species) and collates and manages these data records, maps and habitat data from across the islands, and maintains information about sites recognised for their natural value. Our aim is to enable easy access to biodiversity information to all those who need to use it whilst maintaining security and quality of data. The GBRC continues to develop so that a wide variety of biodiversity data both recent and historic are collected, stored and used.

Environment Guernsey manages the records centre on behalf of La Société Guernesiaise and the States of Guernsey Environment Department to provide a ‘one-stop-shop’ for information on sites, habitats and species in the islands that make up the Bailiwick of Guernsey. Our services are essential for underpinning policies and decision making in both the public and private sector, and to ensure compliance with local and international legislation. We are strongly supported by local volunteers with expertise in ecological surveys, species identification and data management and, as such, are able to offer services in a highly cost-effective way.

The Manager

Jane Gilmour

Botanist and Ecologist with over 30 years experience in the field in Guernsey, including taking part and organising in various surveys, such as the survey of our quarries and of plant galls. I currently co-ordinate a ‘tunnels and fortifications’ bat study. An exciting discovery is that the Greater Horseshoe Bat is here for at least part of the year. We had considered it extinct so this is great news.

I am a past Chairman of both the Reserves and Scientific Committees of La Société Guernesiaise and the current BSBI vice-county recorder for Guernsey and Herm. I can be found surveying and recording a variety of plants and animals, as well as taking part in practical management activities such as raking grasslands and removing invasive plants.

I also garden with wildlife in mind, especially looking at ways of ensuring a wide range of native animals and plants can be accommodated in such confined spaces. Bumble bees are a particular focus, as their numbers can be dramatically influenced by sympathetic planting and management and they are suffering badly due to loss of habitat, not helped by the recent extremes of weather.

Our Technology

The original Distmaps database programme

This was created by the late Charles David from 1992 to 2009.  Charles had been programming for many years, but, as a field entomologist and botanist, he wanted a programme that would enable him to create and maintain a computer database of records with a mapping ‘front end’. He was keen to develop one that would enable the easy input of records, particularly where there may be only one or two in any one area, and where the records could then be viewed as a map and could be viewed in conjunction with other data such as habitats or physical features such as roads, streams etc.  This programme does that and much more.  It includes all the islands and enables us to keep an eye on the fortunes of threatened species and the rise in invasive non-natives as well as building an understanding of the pattern of habitat use and so significance of various areas locally.

ARCMAP/GIS mapping technologies

This is a well-known programme and will not need any further introduction to most.  Data from Distmaps can be loaded into this mapping programme, so providing further flexibility in reviewing plant and animal data.

The new Distmaps Pro database programme

This is a project within ArcMap Pro and installed in May 2018. We are currently finding our way round the new software. It incorporates the features of the original Distmaps, but in the context of the latest mapping technology.
