The grid scheme with 342 squares currently used for the floristic surveillance of Vladimir Oblast, Russia (5′ lat. x 10′ long.).

There were 335 grid squares in the initial scheme (white squares). Subsequently, Seregin (2012) added Л0 and C0, whereas Seregin (2014) added A0 and Д0. In 2018, three grid squares (Б0, Л25 and М22) were included for the better curation of some small areas of Vladimir Oblast outside the regular grid. The squares added during 20112018 are shown here in grey.
