Isidia and soredia are good sources for the vegetative propagation of lichens because they are produced
in large quantities and propagation can thus be accomplished while using the least amount of lichen
material. The aim of this study was to find appropriate techniques in increasing the biomass production of
lichens in the tropics. Transplantation was done through spreading Parmotrema tinctorum isidia and P. praesorediosum
soredia on double-sided adhesive tape (DSAT) and thereupon fixing the lichen materials on the bark
of tree trunks in different types of tropical forest at Khao Yai National Park, Thailand. The survival rate of the
transplanted isidia and soredia was only 9% and 8% with those transplanted to secondary forest (SF) growing
into large thalli. Alternately, transplantation using P. sulphuratum isidia with the same materials, but fixing the
DSAT on nylon nets installed at 0°, 45° and 90° inclinations was executed in SF. The highest germination rate
for isidia was as much as 50% which was found on a substrate at 45° inclination two years after transplantation.
Transplantation in a shaded microhabitat using P. sancti-angelii soredia and P. tinctorum isidia to a substrate at
45° inclination was performed. After three years as much as 90% of the soredia and 70% of the isidia survived
and developed into young thalli. In conclusion, appropriate techniques were achieved for transplanting lichens
in the tropics utilizing the least amount of lichen material. They are essential for conservation and sustainable
utilization of lichens in a changing world.

The greatly increased taxonomic understanding of Iran’s lichens in the past decade is primarily due to
the combined effort of both Iranian and non-Iranian scientists. As a result more than 285 lichen species have
so far been recorded from northeastern Iran. As a continuation of this work further investigations were made in
two reserves in Khorasan provinces (NE Iran). Eighty specimens were collected from 10 localities in Darkesh
(Ala Dagh Mt.) and Tandoureh (Kopet Dagh Mt.) influenced by Euro-Siberian and Irano-Touranian phytocoria,
respectively. First hand observations of these, combined with a critical literature survey, indicate four new species
not previously found in Iran.
