Comparative Investigations of the Ecosystems in Croatia (1st piase) Summary The authors inform on the organization of permanently plots for long term investigations of ecosystems in Croatia. A number of plots will include important natural and antropogenic ecosystems on the horizontal and vertical profiles of all biogeographical regions in Croatia, in agreement with the conclusions of the Yugoslav Ecological Society and Croatian Ecological Society. So far 26 plots have been established in norhern Croatia including 20 forest ecosystems, 2 grassland, 2 swamp and 2 agroecosystems.. . The investigations started in several ploth. The total biomass was measured in the layer of herbaceous plants and shrubs on the plot of Opeke — Lipovljani. The results show that accumulated biomass of this layer amount to 1371,939 kg of fresh biomas per ha (or 764,717 kg of dry biomass). Two plots with maize and oat are also protected and the floristic composition of these stands was investigated. The maize field is situated in the eastern part of Croatia (Vukovar — Jelaš) where one could expect the hoe weed vegetation belonging to the alliance Eragrostidion. However, the weed coverage and floristical composition are very poor because of herbicide treatment. The other field situated in western Croatia (Petrinja) was covered by oat, but cultures rotated each year. The plot with grassland and swamp vegetation is situated near Okučani (central Croatia). The grassland vegetation belongs to the association Trifolio-Agrostietum stoloniferae Markovie 73 (class Molinio — Arrbienatheretea), and the swamp vegetation belongs to the classes Isoeto-Nanojuncetea and Phragmitetea. 218 |
