“…The improvement of water quality and environment certainly provided prerequisite for the germinations. However, Rosenthal (2006) found that a large species pool (e.g., as a consequence of moderate human alterations to the river) was important for the restoration success of riparian wetlands. From the present study, it seemed that the reintroduction of indigenous plant species through planting could be an alternative measure to construct species pool over a relatively short term.…”

In the past three decades, the fast development of economy and urbanization has caused increasingly severe pollutions of urban water bodies in China. Consequently, eutrophication and deterioration of aquatic ecosystem, which is especially significant for aquatic vegetation, inevitably became a pervasive problem across the Yangtze River Basin. To rehabilitate the degraded urban water bodies, vegetation replanting is an important issue to improve water quality and to rehabilitate ecosystem. As a case study, a representative polluted urban river, Nanfeihe River, in Hefei City, Anhui Province, was chosen to be a rehabilitation target. In October 2009 and May 2010, 13 species of indigenous and prevalent macrophytes, including seven species emergent, one species floating leaved, and five species submersed macrophytes, were planted along the bank slopes and in the river. Through 1.5 years' replanting practice, the water quality and biodiversity of the river had been improved. The concentrations of total nitrogen (TN), total phosphorus (TP), and ammonia nitrogen (NH 4 + -N) declined by 46.0, 39.5, and 60.4 %, respectively. The species of macrophytes increased from 14 to 60, and the biodiversity of phytoplankton rose significantly in the river (p<0.05). The biomasses of zooplankton and benthos were also improved after the vegetation replanting. The study confirmed that vegetation replanting could alleviate the increasing water pollution and rehabilitate the degraded aquatic ecosystem. The case study would be an example for polluted urban waters restoration in the middle-downstream area of Yangtze River Base.

The management regime may have a significant impact on the productivity and dynamics of grasslands, but the causal relationships influencing grassland conservation value are still not completely understood. Changes of selected community characteristics, such as standing crop, proportion of forbs in the standing crop, litter amount, litter decomposition and seedling recruitment, were investigated in a 4 year manipulative experiment in a mountain grassland in Slovakia. The aim of the research was to compare changes in newly abandoned sites and sites where restoration measures were applied after 20 years of abandonment. The sites were located in areas containing two vegetation types of the Arrhenatherion alliance (wet Poo-Trisetetum and dry AnthoxanthoAgrostietum) with different moisture regimes. The expected increase of the standing crop after abandonment was rather slow, and more pronounced towards the end of the experiment, and in the wet meadow type (*30% increase). The restoration mowing promoted forb proportions in the biomass, but it did not decrease the standing biomass in the restored grasslands. Strong litter accumulation after abandonment was observed in subsequent years after abandonment, when the amount of litter increased about 100% in abandoned plots. Decrease in litter was also significant after the start of restoration mowing (a decrease from 258 to 159 g m -2 in wet type and from 287 to 147 g m -2 in dry type was noted). Accumulated litter was negatively correlated to seedling recruitment (r = -0.63 at the end of the experiment). The litterbag experiment showed that the wet type has a higher rate of decomposition, with 20% more biomass decomposed during the litter-bag experiment. The experiment confirmed a negative role of litter accumulation on seedling recruitment, with the number of seedlings per m 2 decreasing from 413 to 321 individuals in the abandoned wet-type site. This may lead to a decrease in species richness. Mowing along with raking of mowed biomass may be a useful tool to restore degraded mountain grasslands and to remove accumulated litter from the stands.

“…Even a strict preservation outside the river influence was advocated, and a restoration of floodplain communities through active seed dispersal . Limited restoration potentials were observed for meadows in the active floodplain due to limited dispersal and recruitment in extant vegetation (Donath et al, 2006;Hölzel, 2005;Rosenthal, 2006). Hegland et al (2001) The colonisation rate means the chance of colonisation for a newly created habitat by a rare species of that community.…”

“…The preservation of relics outside the dynamic flooding zone is suggested to be a necessity for the sustainable protection of these species by several authors (Donath et al, 2003;Hegland et al, 2001;Jongman, 1992;Lindborg & Eriksson, 2004;Van Eck et al, 2004). German research advocates this preservation as a necessity for both conserving genetic diversity and sufficiently strong populations (Eckstein et al, 2004;Eckstein & Otte, 2005;Rosenthal, 2006), as the restoration through the transfer of plant material from species-rich source stands is common practice (Donath et al, 2006;.…”
