If you are one of the The symbiosis gives very specific features lichens, including a high sensitivity to environmental pollutants which makes them excellent indicators of air quality and habitat. This study uses citizen science to investigate national-scale patterns in the distribution and abundance of selected lichen species on tree trunks and branches, and to relate these to . [5] In many cases, lichens are able to get all of the nutrients they need from minute amounts dissolved in water. Flavo as a prefix means yellow, distinguishing these lichens from the blue tint of other shield lichens yellow hues combine with blue so that the overall effect is green.
