Research on eksploration of lichen along the highway solo Tawangmangu
and forest areas Sekipan Karanganyar Central Java has been carried out in January
until February 2016. The research aimed to identify species of lichen in the road of
Solo-Tawangmangu and Sekipan Forest. This research was using qualitative
descriptive with survey techniques. This method established two stations were
stations 1 (Along the Road Solo Tawangmangu) and station 2 (in the forest Sekipan).
The research found 18 species of identification of lichen. Five family that
Parmeliaceae (4 species), Peltigeraceae (1 species), Physciaceae (4 species),
Graphidaceae (4 species), and Calicaceae (5 species). Type morphology was the
dominant type of foliose as many as 8 species followed fruticose type 1 species, the
type squamulose 5 species and 4 species of crustose type. The percentage of lichen
on the second station obtained Physconia sp. 2 (the lowest) equal to 36% at station 1
and Peltigera colina (the highest ) species that 90% at station 2. The traffic density
at station 1 was very crowded It influenced the growth of lichen. At station 2
(Sekipan forest) there was no influence of air pollution. So the growth of the lichen
were very diver. The percentage of lichen coverage was the highest in Station 1 (90
%) was Peltigera colina and the lowest one was the Road of Solo – Tawangmangu
