Atlas 2020 Recording: Priority Tetrads

This map now shows priorities after entry of data at mid-August 2019. 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 end of Atlas 2020 recording at the end of the year. Two tetrads left at Top priority can be discounted for reasons of access or past history, and none with significant land area in the counbty remain at High priority.

61 out of 62 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. 84% 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 the rest of 2019, there are still tetrads that will benefit from some more attention. But one thing we need to do is to check up on old sites for species that haven't been recorded anywhere in a hectad since 1999. Use the new facilities on the web site that will help you track these down. Water plants need particular attention.

We now have no High priority tetrads worth picking up in 2019. All hectads but one now meet our minimum for good coverage, and 84% of them reach our aspirational criterion.

These pages now show priorities for the rest of 2019, based on records entered up to 16th August. Given that data from several recorders is still to come in, our coverage is now looking impressive, and we should be switching 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 in recent years, so more tetrads have dropped back into Medium priority - but as long as the overall hectad coverage is good, don't feel pressured about this.

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.
