Management of the Reeds of Lake Fertő.Biological and Usage Status of the Reeds. István MÁRKUS dr. University of West Hungary Phone: +36-70-571-029 E-mail: Markus.Istvan1@chello.hu 8th LAKEPROMO Seminar and Meeting, Budapest, 10-14 October 2007
Role of reed zone: • Conservation of natural heritage • Fishhabitat • Habitat for native bird fauna and breathing space for migratory birds • Protection of water quality • Defence against tidal wawe • Natura 2000 special protection area (SPA) • Natura 2000 site of community importants (pSCI) • Reed production and utilization • etc. 8th LAKEPROMO Seminar and Meeting, Budapest, 10-14 October 2007

Natural conditions of Lake Fertő: • The area of the lake amounts to 309 km2. The northern part of the lake (234 km2) belongs to Austria, the southern part (75 km2) to Hungary. • The water balance of the lake is instabil. • The average water-depth ison the Hungarian part 1,04 m, in the reed zone several dm. • The prevailing heavy northern winds rises to undulation of water surface. The undulation rouses slime, indicates stream, moving the mud. This effect reguates the bunking up process. • The Fertő is a saline lake. The salinity of water amounts to 1700 mg/l. • The lake is - in point of wiev of lake typology – in elderly stage. 8th LAKEPROMO Seminar and Meeting, Budapest, 10-14 October 2007

Reed management, harvesting • a) by hand (to 1954) • b) machine-made harvesting Major harvesting machine types: • RS-09 reaper • Olympia type reaper • Seiga Tortoise 090 reaper • Swimming reaper. Yield of the harvesting: Before 1990 was aimed the harvesting of the total area. Nowadays less as 1 million sheaf/year. 8th LAKEPROMO Seminar and Meeting, Budapest, 10-14 October 2007
