Final summer priority areas for TTV coverage

We are now down to the last few months of breeding season fieldwork and there are still 33 tetrads remaining to be surveyed so that we achieve our aim of a minimum of 8 surveyed tetrads in every 10-km square.

The map on the right shows the 10-km squares in which fieldwork is still required to meet the target. The colour scheme indicates the proportion of tetrads still required, with darker colours indicating the squares of highest urgency where fewest tetrads have yet been surveyed.

Use the controls to zoom in to an area of your choice. If you click on a square the pop-up message will give you more information about the squares still needed and available.

If you've found an area where you could help, login using the buttons below and visit Request TTVs to see which tetrads are available.
