New web features for Atlas 2020 recorders

If you're recording for the BSBI's Atlas 2020 project, you'll find a new facility on the tetrad listings pages. (Click on the map on the 'Tetrad recording' page to bring up the listing for the clicked hectad. ) When there are tetrads displayed, you'll see new buttons at the top of the scrolling list labelled "Select tetrad, click here for full recording history.." and "..or click here for cumulative species tallies". Use the radio buttons in the normal way to choose a tetrad. The first button pops up panels showing all the dates since the beginning of 2000 when more than 25 taxa have been recorded. Below this is a graph showing the times of year when visits have been made. Hopefully this will guide you towards "gap" times when it might be most productive to go out and re-record. Note that once you have the pop-up on screen, you can update it with data from another tetrad by selecting the new tetrad and clicking the button again - no need to close the pop-up.

Since this feature now shows all the past history for which records have been collected onto the Hants Plants database, the tetrad listings themselves have been changed only to show visits which are relevant to current visit planning: that is, "Proposed", "Cancelled" and "Done" (the last means that the recorder has updated his visit after the event, but the data hasn't yet been transferred to the database. ) This helps to declutter the list, especially now that we have built up several years of logged visits. The recording events shown on the pop-up use actual records submitted, regardless of whether a visit was logged by anyone, and so is a much more complete summary.

The second button shows a graph of the increase in number of species recorded for the tetrad between 2010 and the present against a baseline of the number recorded up to 1999, and a total of all the species ever recorded there. Where there's already been a lot of recording activity, this gives an idea of how productive further visits are likely to be.

Look out for more features soon!
