Descripción: | Picture taken on the 8th April 2007 at Targasonne, Alta Cerdanya, Oriental Pyrenees, France, isolate granite boulder visited by birds, 1.650 m. altitude. It is hard for an amateur naturalist to make lichen sociology in an area that has never been studied before. The only way to go ahead is step by step and with a lot of observation and releves. The present one takes in the top of the boulder, being an homogenous area (Inv 2 - Targasonne). Thanks to all the people that has helped me to enter the wonderful world of lichenology.

Valuation of lichen sociology according to Klement (1955), depending a lot on the thallus sizes: 1 - eingesprengte Einzelpflanzen 2 - kleine Thalli unter 3 cm 3 - mittelgrosse Lager, Rosetten oder Cladoniagruppen 4- grossblättrige Rosetten oder Polster über 20 cm. 5- zusammenhängende Krusten, Rasen oder Decken f means fertile Armand Tomás Vidal Nikon Coolpix 4.500 Autoeye, PH and HTLM Editor |
