EMC Analysis by Land Use Types based on Long-term Monitoring of Nonpoint Source Pollution in Geum River Basin

Bird fauna long-term monitoring in the Romanian lower Prut river basin In the present paper, we give data on the bird' fauna's dynamic during the last 18 years in the Romanian Lower Prut River basin. This valley shelters a good level of the biodiversity being very well protected through the border status, but due the low level of the industrial development, too, despite an increasing of the human pressure in the last years. We recorded in this area some very rare breeding bird species for Romania - Platalea leucorodia, Plegadis falcinellus, Limosa limosa, Recurvirostra avosetta, Himantopus himantopus, Luscinia svecica, etc. but also some globally threatened species like Phalacrocorax pygmeus, Aythya nyroca or Crex crex. In this sector of the Prut River basin three Important Birds Areas (IBA) were delimited, all included in the "Romanian Nature 2000 Network".

Background: Welwitschia mirabilis is highly specialised to survive the harsh climate of the Namib Desert. Changes in land use, such as the expansion of mining activities, may endanger their survival.Objectives: The purpose of this study was to understand the photosynthetic potential of W. mirabilis plants to provide a baseline for future long-term monitoring, and for future comparison to determine plant health status after the onset of mining operations.Methods: The study was conducted in a population of W. mirabilis on the Welwitschia Plains. Chlorophyll a fluorescence data were used to measure plant photochemical potential and analysed using the JIP-test.Results: Significant differences in the photosynthetic potential was observed for W. mirabilis plants located in different catchments. The partial parameters of the PIABS values were also significantly lower, which indicated that all aspects of photosynthesis were influenced.Conclusion: PIABS values can serve as a baseline for future long-term monitoring studies to detect any changes in the health status of W. mirabilis that might result from land use change.

Five streams in catchments with pastoral dairy farming as the dominant land use were monitored for periods of 7–16 years to detect changes in response to adoption of best management practices (BMPs). Stream water quality was degraded at the start with respect to N, P, suspended solids (SS) and E. coli concentrations, and was typical of catchments with intensive pastoral agriculture land use. Trend analysis showed a decrease in SS concentration for all streams, generally increasing water clarity, and lower E. coli concentrations in three of the streams. These are attributed to improved stream fencing (cattle exclusion) and greater use of irrigation for treated effluent disposal with less reliance on pond systems discharging to streams. Linkages between water quality and farm actions based on survey data were used to develop BMPs that were discussed at stakeholder workshops. Generic and specific BMPs were developed for the five catchments. The 3–7 year periodicity of major climate cycles, as well as market forces and a slow rate of farmer adoption of simple BMPs mean that monitoring programs in New Zealand need to be much longer than 10 years to detect changes caused by farmer actions. Long-term monitoring is also needed to detect responses to newly legislated requirements for improved water quality.
