Tidal Swamp

Indonesia has around 20.11 million hectares of tidal swamp land area and about 2.07 million hectare is tidal swamp potential. The results of the inventory report BPTP Lampung in 2012 revealed that the area of swamp land in Lampung Province 108 thousand ha consisting of 56 thousand ha of tidal swamp and 52 thousand ha of lowland swamp.The main issues management of tidal swamp land is the water level always changing and the sulfidic or pyrite layer. Application water system design are good enough to prevent it. The rain distribution on Rawapitu about 39-531 mm during 2013-2014 and there were 2-3 month dry season. The fluctuation of water level on piezometer showed that the areal flooded on December 2013 and April 2014. It has affected the oil palm growth although increasing the number of frond, rachis length, and leaf area indeks.

Water Level Regulation

In Canada, Lipocarpha micrantha has been documented at eight locations in Quebec, Ontario, and British Columbia. Four of these populations have apparently been extirpated. The remaining populations, ranging from 120 to approximately 40000 plants, are all northern disjuncts from the main range of this species. Threats to these populations include water level regulation and shoreline development. Considering the threats to the habitat of Lipocarpha micrantha, and the small size of most of the remaining populations, it has been designated an Endangered species in Canada.

Early Pottery

A case study of the Neolithic comb ceramic site Pezmog 4 of the Kama culture presents a situation when results of radiocarbon dating change long-existing concepts concerning the development of archaeological events. Until the early 2000s, the chronology of the Kama culture, distributed mainly in the Kama and Vychegda River basins, has been based on comparative-typological analysis. Estimates of the age of this culture changed from the 3rd millennium BC in the 1950s to the 1st half of the 4th millennium BC by the 1990s. Research concerning the Pezmog 4 site in the central Vychegda River basin in 1999–2002 has abruptly changed this chronological understanding. The data obtained put the age of the early stage of Kama culture within the time range 5750–5620 cal BC and allowed us to propose the existence of another way of early pottery distribution in the forest zone of eastern Europe at the beginning of the 6th millennium BC. This innovation probably penetrated from the trans-Ural region.
