“…Nevertheless, some species, such as egrets, use thick vegetation cover to hide and stalk prey at the edges of water channels (Bancroft et al 2002). Vegetation cover also stabilizes the channel banks and provides habitat for both fish and invertebrates within the drains (Vought et al 1995). Aquatic vegetation may also be directly consumed by the waterbirds (Keddy 2010).…”

Oil palm expansion is a major driver of habitat loss in the tropics. Although a number of studies have evaluated the consequences for terrestrial biodiversity, the effects on wetland habitats and fauna are less well described. This study aims to determine the conservation value of flood-control drainage channels in oil palm smallholdings for waterbirds. We also measured the water quality (water temperature; pH; dissolved oxygen, DO; total dissolved solids, TDS; salinity; water depth; conductivity; and turbidity) and habitat characteristics (vegetation cover and channel width) to determine the relationship between waterbird species richness, water quality, and habitat characteristics. Birds were surveyed along 25 line transects within peat swamp-and mangrove-converted oil palm smallholdings. Data were collected in seven smallholdings between March and December 2013. We recorded a total of 1111 waterbirds from eight resident species. Both mangrove forest-and peat swamp-converted smallholdings had similar waterbird diversity. Waterbird species richness increased with increasing DO and decreased with water depth, temperature, and conductivity. The most parsimonious predictive model (minimum quasi Akaike information criterion = 476.48) explained 52.39 % of the variation in species richness. Our data indicate that even manmade aquatic habitats, such as flood-control channels, can be important for some waterbirds in oil palm smallholdings. However, considering the relatively small increase in waterbird species richness in channels, the most successful strategy for conserving waterbirds will require protection of intact wetlands supported by better management of drainage channels in oil palm smallholdings.

“…TP concentrations tended to increase with surrounding cropland, but multiple ponds had high (>3 mg/L) TP and no cropland within 100 m of wetland survey points, suggesting that macroinvertebrates may respond to anthropogenic and livestock inputs and impacts that occur at larger scales. Riparian buffer strips can greatly improve the quality of agricultural wetlands by reducing nutrient loading, erosion and other contaminants entering the water due to surface run-off (Schulte et al, 2017;Vought, Pinay, Fuglsang, & Ruffinoni, 1995 2014). Protecting and/or restoring riparian zones could also prevent shifts in higher trophic levels from specialized to generalized insectivores due to changes in relative abundances of primary producers (Blann, Anderson, Sands, & Vondracek, 2009).…”

Aim Wetland loss and degradation threaten biodiversity to an extent greater than most ecosystems. Science‐supported responses require understanding of interacting effects of land use and climate change on wetland biodiversity. Location Alberta, Canada. Methods We evaluated how current climate, climate change (as a ghost of the past), land use and wetland water quality relate to aquatic macroinvertebrates and birds. Results Climatic relationships and climate–land use interactions were observed on chironomid abundance, but not macroinvertebrate taxa richness (MTR) or odonate abundance, which responded to land use and water chemistry. Chironomid abundance was positively associated with cropland and negatively associated with total precipitation. Higher cropland cover and dissolved organic carbon synergistically interacted with total precipitation to affect chironomids. MTR was negatively related to salinity, yet greater area of non‐woody riparian vegetation attenuated salinity effects on MTR. Odonate abundance was negatively related to total phosphorus. Higher grassland cover also increased the negative relationship of total phosphorous to odonate abundance. Climatic relationships and climate–land use interactions were observed on bird species richness (BSR) and abundance of several bird functional groups. Higher BSR and abundances of several bird groups were positively related to average rainfall and greater warming temperatures over time. Area of non‐crop cover and wetlands was positively associated with most bird groups and BSR. Warming temperatures over time ameliorated the negative relationship of higher cropland or less shrubland on aerial insectivores and other bird groups. Main conclusions Climate patterns and climate change are as important as land use pressures with stronger impacts on birds. Climate change was more influential than current climate and provided novel empirical evidence that progressively warmer, wetter conditions is benefiting some bird groups, including aerial insectivores, a group of conservation concern. Riparian vegetation ameliorated the negative impacts of climate and water quality gradients on MTR and could mitigate global change impacts in agricultural systems.

“…John B. Dybkjaer, Annette Baattrup-Pedersen,* Brian Kronvang, and Hans Thodsen T he ability of riparian areas to capture or buff er sediment and nutrient losses from agricultural fi elds in catchments before they enter water bodies such as streams, lakes, reservoirs, and estuaries has increasingly been used during the last decade to reduce sediment and nutrient losses to surface waters (Sharpley et al, 1994;Venterink et al, 2003;Kronvang et al, 2008Kronvang et al, , 2009. Th e processes involved include mechanical trapping of sediment-bound nutrients, denitrifi cation of nitrate, and sorption of inorganic P to iron and aluminum hydroxides (Vought et al, 1995;Hoff mann et al, 2006Smith et al, 2008). Recently, emphasis has been laid on the importance of riparian areas for maintaining and enhancing biodiversity in agricultural environments (e.g., Sabo et al, 2005), refl ecting that riparian areas are core habitats for a wide range of semiaquatic and terrestrial species and can function as wildlife corridors linking habitat patches in an agricultural landscape (Forman, 1995).…”

Diversity and Distribution of Riparian Plant Communities in Relation to Stream Size and Eutrophication

Th e present study was conducted in 47 diff erent riparian areas distributed throughout Denmark to investigate diversity and distributional patterns of plant communities along a lowland stream size gradient (fi rst to fi fth order). Th e investigated areas were representative for Danish riparian areas not in use for agricultural production. We investigated plant community richness along a stream size gradient and the infl uence of eutrophication on the abundance of diff erent plant communities. Vegetation analyses were performed in transects placed perpendicular to the stream channel, with a total of 1798 plots analyzed. Overall, we found a positive relationship between stream mean depth as a measure of stream size and the number of plant community types identifi ed in the riparian areas. We also found that the abundance of the identifi ed communities was positively correlated with their nutrient preference and negatively correlated with their moisture preference. Th e abundance of alkaline fens and Molinia meadows (protected community types) in riparian areas decreased with increasing size of the stream, whereas the abundance of humid meadows and wet herb fringes increased with increasing size of the stream. Based on our fi ndings, we recommend that wide buff er zones be established along streams with protected habitat types in the associated riparian areas to reduce the direct impact from agriculture. Furthermore, we recommend that wide buff er zones be established along middle-sized and large streams because several community types may develop.
