Preliminary checklists for applying SERCON (System for Evaluating Rivers for Conservation) to rivers in Serbia

Abstract

This paper describes the first steps in gathering biological data to assess the conservation value of rivers in Serbia, using SERCON (System for Evaluating Rivers for Conservation). SERCON was developed in the UK to improve consistency in assessments of river ‘quality’ by using a scoring system to evaluate habitat features and species groups, catchment characteristics, and the potential impacts to which river systems may be subjected. This paper provides checklists for aquatic, semiaquatic and marginal plants, macroinvertebrates, fish and birds associated with rivers in Serbia, collated from a wide range of published and unpublished sources. These lists should be regarded as provisional because few wide-ranging biological surveys have been carried out specifically on Serbian rivers; further revisions are likely as more information becomes available in future. Ultimately, the work will benefit regulators and decision-makers with responsibility for river management under the new Water Law, and contribute to river protection and conservation in Serbia.

The effects of physical-chemical water parameters on the Nymphaeion alliance development in northwestern Serbia

“…Bicarbonate values (min = 1.830, max = 4.734) are in the range of variation noted by Smits et al [43] most likely to allow development of edificator Nymphoides peltata. Significantly, the lowest COD-MnO 4 and BOD 5 values, as well as very narrow range of variation in these parameters, was noted in comparison to other analyzed phytocenoses. The highest nitrate and nitrite content in ass.…”

“…Nymphoidetum peltatae habitats, the mean COD-MnO 4 values of 7.272 and 6.927 were noted, respectively. Statistically highly significant differences in terms of COD-MnO 4 were found between localities populated by ass. Nymphaeetum albae and ass.…”

“…Water samples were taken at locations minimum 400 m apart. Basic physical and chemical water properties were determined according to standard methods [38] 4 3− and total phosphorus). The water chemical analysis data pertaining to the aforementioned parameters was processed using STATISTICA 7.0 software [39].…”

“…1956 alliance play an important role in the shallow aquatic ecosystems [1]. Nymphaea alba, Nuphar lutea and Nymphoides peltata have least concern status on the "Red list of threatened species for Europe" [3], while N. alba and N. lutea have strictly protected national conservation status in Serbia [4]. Nymphoidetum peltatae stands in aquatic vegetation of Vojvodina are in the withdrawal phase [5].…”
