Annotation:

Howard Thomas Odum (1924-2003) was an important transitional figure in the development of wetland ecology in the United States. Although he was educated before wetland ecology became a recognized subdiscipline of ecology, his research during the first half of his academic career (ca. 1950 to 1975) was focused primarily on wetlands. By the early 1970s, he was self-identifying as a wetland ecologist, e.g., by establishing the Center for Wetlands at the University of Florida. Although Odum was interested in much more than wetlands, especially during the last half of his lengthy career, he contributed significantly to increasing the visibility of wetlands and to the development of wetland ecology in four principal ways: (1) his innovative and influential research on the trophic structure of Silver Springs, a riverine wetland; (2) his highly visible research on the use of Cypress Domes to treat waste water; (3) his establishment of a major academic, wetland research institute, the Center for Wetlands; and (4) his many graduate students who obtained influential jobs in academia, government agencies and private companies. When Odum started his academic career wetland ecology did not exist. Halfway through it, wetland ecology began to arise as a distinct discipline and Odum was one of the major reason why this happened.

Annotation:

There is a tremendous diversity in wetland types and wetland vegetation in the United States, caused primarily by regional, geologic, topographic, and climatic differences. Wetland hydrology, a primary driving force influencing wetland ecology, development, and persistence, is as yet poorly understood. The interaction between groundwater and surface water and the discharge–recharge relationships in wetlands affect water quality and nutrient budgets as well as vegetative composition. Hydrologic considerations necessary for an improved understanding of wetland ecology include detailed water budgets, water chemistry, water regime, and boundary conditions. Wetland values are often based on perceived wetland functions. These hydrologic functions include (i) flood storage and flood-peak desynchronization, (ii) recharge and discharge, (iii) base flow and estuarine water balance, and (iv) water-quality regulation. Expanded research and basic data collection focussed on wetland hydrology and its relation to wetland ecology are needed to identify and quantify the hydrologic functions of wetlands.

Annotation:

Many natural wetlands have been converted to human-influenced wetlands. In some instances, human-influenced wetlands could provide complementary habitats for waterbirds, compensating for the loss of natural wetlands. Inner Deep Bay in Hong Kong is composed of both natural and human-influenced wetlands and is under immense development pressure. From an ecology perspective, we need to understand if different wetland types play the same ecological role. To achieve this, we tracked nine little egrets (Egretta garzetta) using GPS loggers for 14 months to study their spatial ecology, home range, movement and habitat use. We found that over 88% of the home range of all individuals comprised of wetlands (commercial fishponds, mangrove, gei wai, channel, and intertidal mudflat). Among these wetland types, nearly all (seven of nine) individuals preferred commercial fishponds over other habitats in all seasons. Little egrets exhibited seasonal movement and habitat use among seasons, with largest home range, greatest movement, and most frequent visits to commercial fishponds in winter compared to spring and autumn. Our results highlight the significant role of commercial fishponds, providing a feeding ground for little egrets. However, other wetland types cannot be ignored, as they were also used considerably. These findings underscore the importance of maintaining a diversity of wetland types as alternative foraging and breeding habitats.

Annotation:

Wetland conservation has gradually improved worldwide. In situ conservation is effective in protecting valuable wetlands. Here, we review the expansion, reformation and problems associated with wetland conservation in China. The wetland conservation system in China comprises a wetland protected area network (nature reserves, wetland parks, urban wetland parks, aquatic germplasm reserves and special marine reserves) and a wetland grading system. Following rapid expansion, national wetland protected areas cover 4.78% of the country. At the same time, a wetland grading system that categorises the importance of wetlands has expanded to 13 provinces. However, reforming wetlands, including improving the role of wetlands, adjusting departmental responsibility, reforming conservation systems and implementing comprehensive wetland conservation regimes, is somewhat arduous and complicated at present. Although these changes have contributed to wetland conservation in China, the wetland conservation system still faces considerable problems because of a lack of uniform and efficient regulations. Management functions and spatial scope overlap in different systems, and there is a disconnect between resource management and law enforcement. A unified legal system and wetland identity cards should be established, with stronger law enforcement. Synergy between wetland conservation systems should improve, innovative wetland conservation mechanisms should be used and better coordination among different protection systems is needed.

This is a historical overview of the role that wetland science has played in regard to wetland management policy in North America. The major focus will be U.S. based since this is where wetland science has a direct link to policy and vice versa. From an international perspective – please see the book- Sustaining the World’s Wetlands: Setting Policy and Resolving Conflicts. The linkage of wetland science to policy has not always been symbiotic as one can see from this article, but even the problematic nexus issues are instructive. This author relied heavily upon Environmental Law Institute’s National Wetland Newsletter from 1986 to 2016 as a major guide to policy versus wetlands science issues besides relevant journal articles, books, and other sources. For an in depth look at the history of U.S. wetlands and for coastal wetlands, readers are referred to Discovering the Unknown Landscape: A History of America’s Wetlands and Tidal Wetlands Primer: An Introduction to Their Ecology, Natural History, Status, and Conservation, respectively.

Annotation:

The decline of wetlands, including those in the Great Lakes coastal zone, prompted the Government of Ontario to initiate steps towards a wetland management policy in 1981. Wetland inventory and evaluation in southern Ontario began in 1983. To date, 1982 wetlands have been evaluated totalling 390 000 ha. These include 160 coastal wetlands, 64 of these on Lake Ontario and the remainder on the other Great Lakes and connecting channels. Current wetland conservation initiatives are outlined including the Wetlands Planning Policy Statement and Conservation Lands Act. Although the values of Ontario's coastal wetland areas are increasingly being recognized, there has been no comprehensive study to show patterns in coastal wetland ecology. Aided by analysis of variance, ordination, and cluster analysis, we show patterns of variation in wetland and site types, soils, dissolved solids, vegetation complexity, and rare flora and fauna which differ between wetlands along Lakes Ontario, Huron, Erie, St. Clair, and connecting channels. Wetlands of Lake Huron reflect a more northern species composition, less organic soil, and more swamp and fen habitat. Along Lakes Erie, Ontario, and St. Clair the predominant marshes have smaller swamp components, organic soils, and considerable dissolved solids.

Annotation:

We compiled available data and information on the global and regional areas (Ramsar regions), and changes in area, of 22 classes of marine or coastal and inland wetlands. From those classes for which there is information, inland natural surface wetlands (forming ~77% of total surface wetland extent) are dominated by non-forested peatlands, marshes and swamps on alluvial soils, with peatlands forming ~33% of natural inland wetlands. The smaller area of marine or coastal wetlands (~10% of total wetland extent) is dominated by unvegetated tidal flats and saltmarshes. Largest areas of human-made wetlands for which there is information are rice paddy and water storage bodies, with a much smaller area of tropical oil palm and pulpwood plantations. These human-made wetlands are all increasing in area. The reported decline in global natural wetland area is occurring across almost all classes of inland and marine or coastal natural wetlands. Total global wetland area estimated from these wetland classes is between 15.2×106 and 16.2×106km2, similar to recent global wetland area estimates derived from remote sensing. Given the considerable data gaps for area of wetland classes, even the most recent other estimates of global wetland extent are likely to be underestimates.

Annotation:

Accelerating and severe wetland loss has made wetland restoration increasingly important. Current wetland restorations do not take into consideration the ecological adaptability of wetland plants at large scales, which likely affects their long-term restoration success. We explored the ecological adaptability, including plant life forms and phylogenetic diversity, of plants across 28 wetlands in China. We found that perennial herbs were more common than annual herbs, with the proportion of perennial herbs accounting for 40–50%, 45–65%, 45–70%, 50–60%, and 60–80% of species in coastal wetlands, human-made wetlands, lake wetlands, river wetlands, and marsh wetlands, respectively. A ranking of phylogenetic diversity indices (PDIs) showed an order of marsh < river < coastal < lake < human-made, meaning that human-made wetlands had the highest phylogenetic diversity and marsh wetlands had the lowest phylogenetic diversity. The nearest taxon index (NTI) was positive in 23 out of 28 wetlands, indicating that species were phylogenetically clustered in wetland habitats. Dominant species tended to be distantly related to non-dominant species, as were alien invasive species and native species. Our study indicated that annual herbs and perennial herbs were found in different proportions in different types of wetlands and that species were phylogenetically clustered in wetland habitats. To improve wetland restoration, we suggest screening for native annual herbs and perennial herbs in proportions that occur naturally and the consideration of the phylogenetic similarity to dominant native species.

Annotation:

Goss Moor NNR is a unique, rare and nationally-important wetland habitat in Mid- Cornwall. The majority of the habitats were created as a result of a long history of tin-stream mining, which ceased in the early 1900s. Phytosociological surveys of poor-fen and willow carr communities provide the first formal descriptions of the vegetation at this site. The poor-fen survey revealed twelve poor-fen vegetation types, which were distributed along a primary environmental gradient of organic matter depth, surface water height and bare substrate. Separation of the poor-fen communities by a moisture gradient was considered as spatial evidence for hydroseral succession, which begins with the colonisation of open-water pools created by tin excavations. The Salix cinerea ssp. oleifolia willow carr was divided by eight understorey communities, according to age, defined by reference to five sets of aerial photographs of Goss Moor taken over the last six decades. The average number of poor-fen species per unit area in the understorey generally decreased with age. This relationship was related to the increase in canopy cover and, therefore, shade. Willow was found to invade areas with the greatest amounts of accumulated organic material and a low water table. In the oldest and driest willow, oak saplings were found, indicating the beginning of secondary woodland. An architectural analysis of willow showed that useful age descriptors were the height of the first fork, the number of live secondary shoots, tree height and dbh, all of which generally increased with age. Spatial successional patterns were characterised using the lattice-wombling technique in three large rectangles or 'tranomes'. Plant communities were associated with either abrupt or diffuse boundary types. Abrupt boundaries or ecotones were found between heath communities and densely vegetated tall-herb fen and species-poor willow carr wetland vegetation. Diffuse or ecocline transitions occurred between communities with subtle differences in their composition. Spatial relationships between swamp and poor-fen communities were taken as evidence for space-for- time successions, these patterns varied according to location and microtopography. Investigations into the water regime showed water depth was governed by substrate heterogeneity. Homogeneous microtopography was associated with deep inundations and greatest amplitude in water depth, and most closely resembled rainfall fluctuations. The most complex microtopography resulted from the most intense tin-streaming activity. Therefore the anthropogenic history of Goss Moor plays an important role in governing the contemporary water regime and vegetation distribution. Of the wetland communities, rush pasture was the driest and poor-fen the wettest. The communities of open habitats were wetter than the willow communities. The youngest willow community was drier in the summer than the other five vegetation types studied, which was indicative of the conditions necessary for willow scrub colonisation to take place. The N:P ratio revealed that nitrogen was the limiting nutrient in all of the wetland vegetation types suggesting an early stage of successional development. High water levels were thought to be responsible for the prevalence of N-limitation on Goss Moor, creating deoxygenated substrates and leading to the demise of nitrifying bacteria and thus a reduction in the rate of soil N mineralisation. Plant strategies were used to classify the species from a number of wetland communities ranging from open-water pools to willow carr, in order to apply them to Grime's triangular model. The ten communities were ordered into a logical successional sequence. However, the model needs to be modified to account for succession in the aquatic environment. Based on the findings of this thesis, a number of suggestions were made for the effective management of the wetland habitats on Goss Moor. These include: evaluation of willow scrub before removal so those areas of vegetation subsequently opened-up can be monitored; and the creation of new ponds to encourage the growth of certain poor-fen communities, which are species-rich, but only account for a small area of the whole resource.

Annotation:

Stabilized water levels of the upper St. Lawrence River have reduced plant diversity and allowed competitively dominant taxa such as Typha x glauca and Typha angustifolia to displace productive sedge meadow habitat. This research studied the effects of two wetland enhancement techniques using habitat heterogeneity and manipulating hydrology. Dredge spoils from pothole excavations in Typha marshes were reconfigured to create habitat mounds. These habitat mounds created from an exposed seed bank had less Typha spp. and were more diverse than the surrounding remnant Typha marshes. Sedge meadow vegetation did not successfully colonize these habitat mounds. Water levels at two wetlands were raised above the water levels of the upper St. Lawrence River. Raising water levels increased floating leaf aquatic vegetation but did not decrease Typha spp. Alternative enhancement methods may be necessary to control Typha spp. while restoring sedge meadows.

AbstractThe future of wetland bird habitat and populations is intrinsically connected with the conservation of rangelands in North America. Many rangeland watersheds are source drainage for some of the highest functioning extant wetlands. The Central and Pacific Flyways have significant overlap with available rangelands in western North America. Within these flyways, the importance of rangeland management has become increasingly recognized by those involved in wetland bird conservation. Within the array of wetland bird species, seasonal habitat needs are highly variable. During the breeding period, nest survival is one of the most important drivers of population growth for many wetland bird species and rangelands often provide quality nesting cover. Throughout spring and fall, rangeland wetlands provide key forage resources that support energetic demands needed for migration. In some areas, stock ponds developed for livestock water provide migration stopover and wintering habitat, especially in times of water scarcity. In the Intermountain West, drought combined with water demands from agriculture and human population growth are likely headed to an ecological tipping point for wetland birds and their habitat in the region. In the Prairie Pothole Region, conversion of rangeland and draining of wetlands for increased crop production remains a significant conservation issue for wetland birds and other wildlife. In landscapes dominated by agricultural production, rangelands provide some of the highest value ecosystem services, including water quality and wetland function. Recent research has shown livestock grazing, if managed properly, is compatible and at times beneficial to wetland bird habitat needs. Either directly, or indirectly, wetland bird populations and their habitat needs are supported by healthy rangelands. In the future, rangeland and wetland bird managers will benefit from increased collaboration to aid in meeting ultimate conservation objectives.

Considering the increasing number of Urban Wetland Integrated Building Invasions that occur continuously in Sri Lanka, there is little scientific understanding of the optimal design strategies and their relative advantages for ecosystems and humans. The preservation of ecology while adding architectural interventions into sensitive places is a complex procedure, especially when dealing with highly sensitive eco-systems. To wisely integrate buildings with the natural environment of the wetlands, research on the design and application of integrating ESD standards is essential. The primary concept that applies the most to ESD recommendations for wetlands is the "environmental briefing system" (ESD), which is regarded as the most comprehensive and clearly expressed principles and strategies on ESD features. Furthermore, this research extends the framework to include strategies specific to RAMSAR wetlands, comprising 33 distinct methods organized within five primary rationales. This results in a comprehensive framework comprising 63 optional design measures tailored to conserve and protect urban RAMSAR wetlands effectively. In advance, the suggested framework could be used as a benchmark, an evaluation index, or an environmental assessment tool for projects that have already been completed. Additionally, it could be used as a fix-up tool, a checklist for design teams, or a benchmark for projects that are still in the pre-design stages.

The Al-Hammar wetland in Iraq is notable for having the highest densities of coastal migratory birds along the Arabian Gulf-Mediterranean Sea migration line. Despite the importance of these birds, there is no complete evaluation of their dynamics. The six migrating bird species (Mallard duck, Graylag geese, White pelican, Barn swallow, Common gull, White stork) were studied in the area, and the data were compiled and analyzed. Migration patterns have changed over the last two decades, as shown by changes in land cover between October 2000 and 2020 and in bird populations every ten years during the same period. A decrease in the remaining kinds of migrating birds was seen in total numbers between the years 2000 and 2020. Observing trends was impossible due to the extreme disparity between the data sets' respective sizes. A multivariate analysis shows a decrease in the number of species that rely on wetland habitats for food and breeding in the sublittoral and offshore zones of the study area. In comparison to total NDVI values, which decreased by 5%, 3.5%, and 15.6%, total NDWI values increased by 7.8%, 21.0%, and 62.6%. During the research phase. The qualitative characteristics of waterbodies and vegetation have been extensively measured using remote sensing and Gis techniques.

Which kind of imagination do we need to rethink Miami in the advent of sea-level rise? Most of the South Florida region was a subtropical wetland until just 120 years ago. In the land natives called Pa-hay-Okee (grassy river), we build a 20th-century industrial sprawl and completely transformed the ecology of the region by altering significant parts of the wild into rural. This is not an isolated story for South Florida. Today more than 50% of living organisms, plants, and ecological systems in the world are determined by human industrialization.

A vegetation classi?cation and map for Guadalupe Mountains National Park (NP) is presented as part of the National Park Service Inventory & Monitoring - Vegetation Inventory Program to classify, describe, and map vegetation communities in more than 280 national park units across the United States. Guadalupe Mountains NP lies in far west Texas and contains the highest point in the state, Guadalupe Peak (8,751 ft; 2,667 m). The mountain escarpments descend some 5,000 ft (1,500 m) to the desert basins below forming a complex geologic landscape that supports vegetation communities ranging from montane coniferous forests down to desert grasslands and scrub. Following the US National Vegetation Classi?cation (USNVC) standard, we identi?ed 129 plant associations hierarchically tiered under 29 groups and 17 macrogroups, making it one of the most ecologically diverse National Park Service units in the southwestern United States. An aspect that adds to this diversity is that the park supports communities that extend southward from the Rocky Mountains (?ve macrogroups) and Great Plains (one macrogroup) and northward from the Chihuahuan Desert (two macrogroups) and Sierra Madre Orientale of Mexico (three macrogroups). The remaining six macrogroups are found in the Great Basin (one macrogroup), and throughout the southwestern United States (remaining ?ve macrogroups). Embedded in this matrix are gypsum dunelands and riparian zones and wetlands that add further complexity. We describe in detail this vegetation classi?cation, which is based on 540 vegetation plots collected between 2006 and 2010. Full descriptions and diagnostic keys to the plant associations along with an overall plant species list are provided as appendices. Based on the vegetation classi?cation and associated plot data, the vegetation map was developed using a combined strategy of automated digital object-oriented image classi?cation and direct-analog image interpretation of four-band National Agricultural Imagery Program (NAIP) aerial photography from 2004 and 2008 and Landsat Thematic Mapper satellite imagery. The map is designed to facilitate ecologically-based natural resource management at a 1:24,000 scale with 0.5-ha minimum map unit size. The map legend is hierarchically structured: the upper Level 1 consists of 16 map units corresponding in most cases to the USNVC group level, and an additional map unit describing built-up land and agriculture; Level 2 is composed of 48 nested map units re?ecting various combinations of plant associations. A ?eld-based accuracy assessment using 341 vegetation plots revealed a Level 1 overall accuracy of 79% with 90% CI of 74?84% and 68% with 90% CI of 59?76% at Level 2. An annotated legend with summary descriptions of the units, distribution maps, aerial photo examples of map unit polygons, and representative photos are provided in Appendix D. Large wall-size poster maps at 1:35,000 scale were also produced following NPS cartographic standards. The report, plot data, and spatial layers are available at National Park Service Vegetation Mapping Program https://www.nps.gov/im/vegetation-inventory.htm). Outcomes from this project provide the most detailed vegetation classi?cation and highest resolution mapping for Guadalupe Mountains NP to date to support many uses including ?re, recreation, vegetation, and wildlife management, among others. The upper Level 1 map is particularly suited to landscape-scale, park-wide planning and linkages to its sister park, Carlsbad Caverns NP. The Level 2 mapping provides added detail for use at a more localized project scale. The overall accuracy of the maps was good, but because Guadalupe Mountains NP is primarily wilderness park, there were logistical challenges to map development and testing in remote areas that should be considered in planning management actions. In this context, some map units would bene?t from further development and accuracy assessment. In particular, a higher resolution mapping of McKittrick Creek riparian habitat at 1:6,000 scale or ?ner is recommended for this important habitat in the park. In addition, developing a structural canopy height model from LiDAR imagery would be useful to more accurately quantify woody canopy density and height to support ?re management and other habitat management issues. With respect to understanding vegetation dynamics in this time of rapid environmental change, the 540 vegetation plots themselves are su?ciently georeferenced and have the data resolution to be useful in detecting change at the decadal scales across much of the park. To this end, an additional recommendation would be to install more plots to ?ll the gaps among the main vegetation units of the park, both spatially and thematically. Overall, the Vegetation and Classi?cation Map for Guadalupe Mountains NP will support the park?s management e?orts and enhance regional understanding of vegetation and ecology of ecosystems of the southwestern United States.
