Four woody species, Tamarix tentandra Pallas, Populus alba L. and Robinia
pseudoacacia L. (planted) and Amorpha fruticosa L. (naturally colonized) were
studied at two fly ash deposit lagoons, weathered 3 (L1) and 11 years (L2).
All species were assessed in terms of their invasive ability, photosynthetic
efficiency, photosynthetic pigments and damage symptoms, while the
characteristics of the habitat were assessed in terms of trace element
content and the pH and EC of the ash. A reduced vitality of all populations
growing on the ash was observed, except for the naturally colonized A.
fruticosa. High vitality on all sites, except at L2, increased chlorophyll
content and absence of damage symptoms indicates a tolerance in relation to
the uptake of toxic elements from the ash. Therefore, the characteristics of
naturally colonized species can be used for modeling future actions of
biological restoration of fly ash deposits.
