Wall board: Frost scale, 130x91 cm

MACHINE TRANSLATION (not authorised yet)

The large, legible educational chart shows the structure of lichens (lichen fungi) and the scale of lichens. On the board there are 7 air pollution zones defined by lichen species existing in these zones - their drawings are presented in each zone on the board. Lichens (lichen fungi) are good indicators of air pollution (indicator species), therefore thanks to the knowledge of lichen zones it is possible to preliminarily determine the state of air pollution in a given area. The board is laminated, mounted in rods with a hanger.
Dimensions: 130 x 91 cm.
