Abstract/Contents:"It is a major problem each autumn to get rid of the large quantities of leaves produced by deciduous trees. It can happen that leaves will be blown onto the cleaned areas or by chance some areas may remain uncleaned so that the leaves lie there for a longer period. There are very few investigations into what happens to these leaves which lie about in heaps. To obtain information on this subject, the leaves of trees commonly used in town planting were stored in 1 m₂ wooden frames for one year. The reduction in leaf volume was qualified as was also the progress in the leaf decomposition process. After one year the volume of leaves was found to be reduced by over 65 percent in the case of Acer saccharinum, Populus x berolinensis and Ulmus carpinifolia. An approximately 50 percent reduction was noted by Acer platanoides, Castanea sativa, Quercus petraea, Quercus robur and Quercus rubra. The smallest reduction in leaf volume was found in the case of Fagus sylvatica and Platanus x hybrida leaves, where a 40 percent level was recorded. A very advanced state of leaf decomposition by Acer patanoides, Populus x berolinensis and Ulmus carpinifolia was found. The leaves were no longer recognizable and ony the petioles and main leaf veins remained, sticking out of the leaf remains. The leaves of the other species were, for the most part, still intact. However, the leaves in the middle of the heaps showed in some cases an advanced state of decomposition. It can be stated, that the leaves of numerous species create few problems during their degradation whereas the leaves of some others may cause problems even after a year has elapsed."
