Atlas update this winter

In the York Region, we have a good spread of coverage for the winter. However, some 10km squares are more of a priority for allocation of Timed Tetrad Visits to ensure an even effort across the region: SE56, SE57, SE65, SE66 and SE76. That's not to say there is a problem in these, just that other areas have more squares allocated.

The key aims are to:
* get these allocated tetrads visited twice for the winter,
* complete the winter visit for those only visited once previously,
* boost species lists with Roving Records, and
* make sure that there have been after dark visits to all 10km squares to listen for nocturnal and crepuscular species - although most areas already have records for Tawny, Barn and Little Owl.
