The Project

The Anglesey Water Vole Project was established in 2001. The main aim of the project is

”To arrest the decline of, and to enhance the water vole populations on Anglesey such that population networks are viable in the long-term.”



Project Objectives

  1. To conduct water vole surveys in order to assess the distribution of water vole populations on Anglesey
  2. To monitor water vole populations in order to assess their long-term viability
  3. To initiate habitat creation/habitat enhancement projects
  4. To monitor the spread of American mink (Mustela vison) from the mainland and take appropriate action to avoid their establishment on the Island
  5. To raise awareness locally about the plight of the water vole


Historic and Existing data

Prior to the use of AditSite, an in-house database (Microsoft Access) was used to hold information on vole and mink sightings, sites of interest, surveyors and landowners. While this database safely stored the data collected it did not allow the  reporting and analysis required to support the work of the project. Clearly there was a requirement to load this existing data into AditSite. Because of the complexity of the existing data records and their interrelationships this was achieved with the Adit support team providing a custom loader. This got the new system off to a good start with some 1500 records - not a massive data load but far preferable to keying it in again from scratch.

As soon as the records were loaded, it was possible to run standard reports and graphs, and begin to analyse the data. Most interestingly, it was possible to map records across the survey area and AditSite made it possible to map details of the relevant surveyors and landowners alongside the data recorded on the water voles.



Special Needs and New Ideas

Basic vole recording was obviously no problem - very much what AditSite is for. This particular project was looking for something more. It was important to also take note of extra information relating largely to habitat (for example the type of water course, bank substrate, current land use, fencing, stock impact, vegetation types) as well as recording more normal things like other wildlife species.

Initial consideration was given to extensive use of the existing facility for AditSite user-defined fields. However the sheer volume of additional data together with the need to impose some structure upon it made that solution look less attractive. What was needed was an extra detail screen dedicated to the needs of the Vole Project that could be accessed during normal data input.

The AditSite support team took into consideration that fact that the Vole Project might well wish to refine their data input screen in the light of experience and that other projects and organisations might have a similar requirement in the future. The new, user defined, Document Input Screen was born as a standard AditSite feature. This allows AditSite users to define a custom data entry screen with their own data fields, captions and selection lists (probably the most useful feature of all).

The data collected by the custom screen is stored as embedded XML* within a special AditSite database field. The stored data can be selected, reported and plotted just like any other data recorded using AditSite.

The Anglesey Water Vole Project works very closely with several other organisations (CCW, Environment Agency, etc) both on the island and on the adjoining mainland, and needs to share data with them. Because of varying computer-based and manual systems, extensive use is made of the data export facilities within AditSite. Should other organisations join or contribute to the project then the AditSite support team will be there to ensure that any unique data interchange requirements can be met.



More Information on the Water Vole

The Water Vole (Arvicola terrestris) have been in sharp decline in the UK since the beginning of the 20th Century. The decline has been attributed to habitat destruction, water level changes and predation (in particular) by the American Mink. There are many water vole projects around the UK looking for your support. Work to arrest the decline of the water vole population ranges from re-creating suitable habitat to captive breeding programs.

* XML stands for eXtensible Mark-up Language. This is fast becoming the data interchange standard for just about every sort of computer based system. It has the advantage of great flexibility combined with the fact that it is possible to make sense of the data without the aid of a dedicated program. Many programs like AditSite (and including your Internet browser) can read and display structured data stored using an XML format.
