About was founded in August 2005 as an interactive tool for the collection of Nature's Calendar or phenology observations. It grew from a simple flash based map (which is still with us) to using Google maps to collect data from the public.

Nature's Calendar includes a Spring Watch and Autumn Watch each year and now has its own domain

The primary aim of is to increase biodiversity awareness by allowing users keep an online map and nature notes. This is found under the My sightings menu. Regular use allows a user to build up an informative wildlife map of their areas of interest. Nobody else can see these maps or nature notes.

One of the keys to the success of is the number of people that Bookmark it and return at regular intervals to 'look in' or add new sightings. The number of users is not dramatically high, but the percentage of return users is over 80%. In other words it has a consistent and dedicated user base, something that is of more benefit to the collection of sightings than a high number of new hits. It was due to these dedicated users that I developed the My sightings feature.

Data verification

  • Sightings entered on the maps which fall within the normal 'experience' of a species and with a valid email address are accepted.
  • Sightings with an invalid email address are deleted from the maps.
  • Sightings with a valid email address and which are 'unusual' will be followed up to 'verify' the sighting.

So the verification procedure is the same as for current paper-based surveys run by wildlife groups.
