Atlas 2020 Recording: Priority Tetrads

This map now shows priorities after the end of the Vice-county Recorders' planned 2018 visit programme. However several of our most prolific recorders still have quite a lot of data for the season to enter up, so expect to see further gains before we close off for the 2019 season early in the New Year. Four tetrads are left at Top priority but two can be discounted for reasons of access or past history, and only one of the two left at High priority is worth more effort.

58 hectads and part-hectads in the county have now achieved basic coverage where at least 20% of tetrads (5 in a full hectad, proportionately less in a part-hectad) have at least 75% of all plants recorded in them logged since 2000. 94% achieve 20% coverage, and 80% reach the gold standard of 40% coverage (at least 10 tetrads in a full hectad at 75% recent recording). Congratulations and a very big "thank you" to everyone who has contributed so far.

For 2019, there are a few tetrads that deserve some more attention. But one thing we shall need to do in 2019 is to check up on old sites for species that haven't been recorded anywhere in a hectad since 1999. Look out for new facilities on the web site over the winter that will help you track these down.

We now have just one High priority tetrad worth picking up in 2019. All but one hectad now meets our minimum for good coverage, and 80% of them already reach our aspirational criterion.

These pages now show an early draft of priorities for 2019, based on records entered up to 3rd January. Given that data from several recorders is still to come in, our coverage is now looking impressive, and in 2019 we can switch some of our attention from "square bashing" to following up on individual species where the post-2000 record is looking thin. Once again, many historical records from the maps in the 1996 Flora have been put onto the database this year, so more tetrads have dropped back into Medium priority - but as long as the overall hectad coverage is good, don't feel presured about this for the coming (final) year.

Click on any hectad (10km square) to get a list of priority tetrads (2km squares) with visit plans, and to download checklists and recording sheets for a tetrad. You can record your own survey activity and plans using the 'Visit plans' tab on this page. Even if you don't record planned trips in advance, please log completed visits retrospectively. This will help us all not to duplicate effort. If you haven't yet received notice of your personal logon details, use the facility on the login form to request them via email.
