The Vegetation of Wet Meadows in Relation to Their Land-use

Wetland biomonitoring approaches are needed to determine when changes in response to stressors are occurring and to predict the consequences of proposed land-use changes. These approaches require an understanding of shifts in biota that occur in response to land-use, data that are lacking for most kinds of wetlands. Changes in floristic composition corresponding to land-use differences at multiple scales (site to 2500 m radius) were characterized for 40 wet meadows associated with prairie glacial marshes in Minnesota (U.S.A.). In general, guild was more useful than species composition for indicating land-use impacts. Site impacts (stormwater, cultivation) and landscape disturbance (agriculture and urbanization, combined), coincide with a reduction in native graminoid and herbaceous perennial abundance (e.g., Carex lasiocarpa, Calamagrostis canadensis, Spartina pectinata). This vegetation is replaced with annuals (e.g, Bidens cernua, Polygonum pensylvanicum) in recently cultivated sites or introduced perennials (e.g., Phalaris arundinacea, Typha angustifolia) and floating aquatics (lemnids) in stormwater impacted wetlands. Ditches also reduce native perennial importance and increase perennials, but only when they are in highly impacted landscapes.     

县级环境监测站标准化建设达标验收预审中应注意的问题

针对江苏省环境监测站标准化建设达标前期验收工作中发现的问题,指出严格验收标准,严把验收质量关,不仅是环境监测工作向深度和广度发展的需要,更是环境管理的需要。提出硬件必须到位,有足够的人员经费,一定的环境监测能力,人员素质和专业技术人员的结构比例,是环境监测标准化建设的核心,各省辖市环境保护局在对所辖县（市）环境监测站标准化建设达标验收预审时尤应注意。

Current practice and shortcomings of EIA in Lithuania

The paper provides an overview of EIA system applications and assesses its effectiveness in Lithuania. A combination of archival research and quantitative/qualitative analysis was used to identify the main shortcomings of the EIA process in Lithuania: subjectivity in forecasting environmental effects, insufficient consideration of alternatives, politicisation of the process and incompetence of authorities involved. The research revealed that a thorough knowledge of EIA procedures and legal requirements may be a solution to these problems, especially when the stages related to forecasting the effects and evaluating the results are strictly reserved for recognized experts. The work concludes on the suggestions to involve in EIA process relevant authorities and to increase the competence of EIA practitioners.
