Ornithocoprophilous community on the top of a granite boulder (Targasonne)





Image Details

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.

Lichens found:

Rhizoplaca chrysoleuca 2.2 f
Rhizoplaca melanophthalma +.2 f
Rhizocarpon geographicum +.1 f
Ramalina capitata 3.3
Ramalina polymorpha +.2
Orphniospora sp 1.3 f
Physcia dubia +.1
Lecanora alphoplaca ? +.1 f
Melanelia stygia +.2 f
Candelariella vitelina 2.2 f
Aspicilia cinerea 2.3 f
Cornicularia normoerica +.2 f
Dimelaena oreina +.3 f
Umbilicaria cylindrica var. tornata +.1 f
Brodoa atrofusca +.2 f
Lecanora polytropa var. alpigena +.1 f
Acarospora nitrophila +.2 f
Lecidia atrobrunea +.3 f
Rhizocarpon geminatum ? +.2
Lecidella sp. +.2

Methodology following:

Sigmatist School (Braun-Blanquet)

Adapted to lichens by Oscar Klement (1955). Prodromus der mitteleuropäischen Flechtengesellsaften .

Following the methodology used in Spain:

J.M. Egea & X. Llimona (1987) Las comunidades de Líquenes de las rocas silíceas no volcánicas del SE de España. Acta Botanica Barcinonensia 36.

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
