Abstract:
Riparian vegetation has an important role in maintaining water stability, one of which is the river. This study aims to describe the structure of riparian vegetation so that its implications can be seen for the conditions of rainbow arfak habitat on the Nimbai River. The study was conducted in three forest types, namely primary riparia forest, secondary riparia forest and open riparia forest. Sample collection of riparian vegetation was carried out by purposive sampling using sample plots. Plots measuring 2 m x 2 m are used to sample seedling and understorey growth, plots measuring 5 m x 5 m for growth at the stake level, while plots measuring 10 m x 10 m and 20 m x 20 m, for growth of pole and tree levels respectively. The identification results obtained a total of 35 species of understorey and 51 tree-level plants in all three types of riparian forests. Based on the analysis of vegetation structure, it is known that the condition of primary riparia forest and secondary riparian forest still relatively supports the life of arfak rainbow fish compared to open riparian forest. Higher tree level density associated with canopy cover which has implications for the temperature of the water to be colder and less fluctuating, input larger litter into the food chain in the river, and hold suspended particles into the river. Also, the function of riparian vegetation in spawning activities, substrate attaching eggs and nursery habitat for arfak rainbow fish larvae. The results of this study indicate the importance of riparian vegetation structure on the condition of rainbow arfak fish habitat. An understanding of the structure of vegetation is also a basic information for efforts to rehabilitate this endemic fish habitat to maintain the existence of a natural population.

Abstract:
Riparian vegetation delineation includes both the process of delineating the riparian zone and classifying vegetation within that zone. We developed a holistic framework to assess riparian vegetation delineation that includes evaluating channel boundary delineation accuracy using a combination of pixel- and object-based metrics. We also identified how stream order, riparian zone width, riparian land use, and image shadow influenced the accuracy of delineation and classification. We tested the framework by evaluating vegetation vs. non-vegetation riparian zone maps produced by applying random forest classification to aerial photographs with a 1 m pixel size. We assessed accuracy of the riparian vegetation classification and channel boundary delineation for two rivers in the northeastern United States. Overall accuracy for the channel boundary delineation was generally above 80% for both sites, while object-based accuracy revealed that 50% of delineated channel was less than 5 m away from the reference channel. Stream order affected channel boundary delineation accuracy while land use and image shadows influenced riparian vegetation classification accuracy; riparian zone width had little impact on observed accuracy. The holistic approach to quantification of accuracy that considers both channel boundary delineation and vegetation classification developed in this study provides an important tool to inform riparian management.

Abstract:
<p>The CASiMiR-vegetation model is a software that recreates the physical processes influencing the survival and recruitment of riparian vegetation, based on the relationship between ecologically relevant flow regime components and riparian vegetation metrics that reflect the vegetation’s responses to flow regime change. Working at a flow response guild level, this tool outperforms equivalent models by overriding various restrictions of the conventional modeling approaches. The potential of the CASiMiR-vegetation model is revealed in its application to different case studies during the development of a holistic approach to determine environmental flows in lowland Mediterranean rivers, based on woody riparian vegetation and fish species. Various modeling circumstances are described where CASiMiR-vegetation model was used with the purpose of sustaining the research addressing the thesis objectives. The main findings already accomplished in this research are highlighted to illustrate the outcomes that can be attained from the use of such a model.</p>

Abstract:
Here we present “CO-RIP”, a novel spatial dataset delineating riparian corridors and riparian vegetation along large streams and rivers in the United States (U.S.) portion of the Colorado River Basin. The consistent delineation of riparian areas across large areas using remote sensing has been a historically complicated process partially due to differing definitions in the scientific and management communities regarding what a “riparian corridor” or “riparian vegetation” represents. We use valley-bottoms to define the riparian corridor and establish a riparian vegetation definition interpretable from aerial imagery for efficient, consistent, and broad-scale mapping. Riparian vegetation presence and absence data were collected using a systematic, flexible image interpretation process applicable wherever high resolution imagery is available. We implemented a two-step approach using existing valley bottom delineation methods and random forests classification models that integrate Landsat spectral information to delineate riparian corridors and vegetation across the 12 ecoregions of the Colorado River Basin. Riparian vegetation model accuracy was generally strong (median kappa of 0.80), however it varied across ecoregions (kappa range of 0.42–0.90). We offer suggestions for improvement in our current image interpretation and modelling frameworks, particularly encouraging additional research in mapping riparian vegetation in moist coniferous forest and deep canyon environments. The CO-RIP dataset created through this research is publicly available and can be utilized in a wide range of ecological applications.

Abstract:
GIS and aerial photographic techniques were applied to assessing riparian vegetation quality in an agricultural landscape formerly covered in lowland rainforest. Canopy cover and width of woody riparian vegetation, both easily determined from remotely sensed data, were investigated as indicators of riparian quality. High correlations between field measurements of canopy cover and width of woody riparian vegetation with several other vegetation attributes indicative of vegetation quality (weed abundance, debris, human disturbance, native species richness) demonstrated that these two habitat attributes were suitable field vegetation quality surrogates. Desktop quality analysis combined GIS measurement of riparian width with aerial photographic analysis of canopy cover. Desktop quality equalled field quality in 78% of cases, with a further 13% showing errors due to clearing or thickening of vegetation after aerial photographs were taken. Bird communities in higher vegetation quality areas comprised mainly rainforest-dependent species, whereas poor quality areas mostly supported birds of open habitats. Bird community diversity and rainforest-dependent bird diversity increased significantly both with increasing levels of canopy cover and greater riparian width, but a combination of these factors explained more variance than each factor separately. Desktop riparian vegetation quality therefore proved a satisfactory indicator of habitat quality for birds in rainforest riparian zones. This quick and efficient desktop method of riparian habitat quality assessment can determine conservation values of rainforest riparian areas with minimal field validation, thereby allowing more effective targeting of appropriate management practices, identification of areas of conservation concern and prioritisation of revegetation and rehabilitation efforts.

Abstract:
<strong>Composition of Aquatic Macrophytes and Riparian Vegetation in Lake Sentani, Papua Province.</strong> Macrophytes and riparian vegetation play an important role in maintaining the balance of aquatic ecosystems. The loss of vegetation components can lead to increased sedimentation and change the microhabitat in the waters. This research aimed to obtain the composition of aquatic macrophytes and riparian vegetation in Lake Sentani, as well as to determine the status of waters and the characteristics of riparian zones in Sentani Lake. The research was conducted from September to October 2014. The sampling of aquatic macrophytes and riparian vegetation was conducted at 5 stations: St.1 (Doyo Lama), St.2 (Donday), St.3 (Deyau), St.4 (Kalkotte), and St. 5 (Jaifuri). Data of aquatic macrophytes was taken using square plot (1 x 1 m2) of 15 plots, while riparian vegetation data used survey method with 10 m transect line from the shoreline. The results showed that there were 10 species of aquatic macrophytes from 8 families and 30 species of riparian vegetation from 18 families. Based on these aquatic macrophytes and riparian vegetation, Lake Sentani is categorized as eutrophic, with the dominant macrophyte being hornworts (Ceratophyllum demersum L.; 135 individuals). Station 4 (Kalkotte) has the largest number of individual aquatic macrophytes (96 individuals). Cogongrass (Imperata cylindrica (L.) Beauv.) was found to be the most abundant species of riparian vegetation in all stations (190 individuals). This is related to the shoreline of Lake Sentani which is largely a sandy soil. Station 5 (Jaifuri) has the largest number of species and the largest number of individual riparian vegetation (344 individuals from 20 species). <br />

Abstract:
Dryland riparian areas are under increasing stress due to expanding human water demands and a warming climate. Quantifying responses of dryland riparian vegetation to these pressures is complicated by high climatic variability, which can create strong, transient changes in vegetation vigor that could mask other disturbance events. In this study, we utilize a 34-year archive of Landsat satellite data to (1) quantify the strength and timescales of vegetation responses to interannual variability in drought status and (2) isolate and remove this influence to assess resultant trends in vegetation vigor for riparian areas across the state of Nevada, the driest state in the USA. Correlations between annual late-summer Normalized Difference Vegetation Index (NDVI) and the Standardized Precipitation–Evapotranspiration Index (SPEI) were calculated across a range of time periods (varying timing and durations) for all riparian pixels within each of the 45 ecoregions, and the variability of these values across the study area is shown. We then applied a novel drought adjustment method that used the strongest SPEI–NDVI timescale relationships for each ecoregion to remove the influence of interannual drought status. Our key result is a 30 m resolution map of drought-adjusted riparian NDVI trends (1985–2018). We highlight and describe locations where impacts of invasive species biocontrol, mine water management, agriculture, changing water levels, and fire are readily visualized with our results. We found more negatively trending riparian areas in association with wide valley bottoms, low-intensity agricultural land uses, and private land ownerships and more positive trends in association with narrow drainages, public lands, and surrounding perennial water bodies (an indication of declining water levels allowing increased vegetative cover). The drought-adjusted NDVI improved the statistical significance of trend estimates, thereby improving the ability to detect such changes. Results from this study provide insight into the strength and timescales of riparian vegetation responses to drought and can provide important information for managing riparian areas within the study area. The novel approach to drought adjustment is readily transferrable to other regions.

Abstract:
The ecological dynamics of riparian areas interact with sediment transport in river systems, which plays an active role in riparian vegetation growth in the floodplain. The fluvial dynamics, hydraulics, hydro-meteorological and geomorphological characteristics of rivers are associated with sediment transport in river systems and around the riparian area. The flood disturbance, sediment with nutrients and seeds transported by river, sediment deposition, and erosion phenomena in the floodplain change the bare land area to vegetation area and vice versa. The difference in riparian vegetation area in the river floodplain is dependent on the sediment grain size distribution which is deposited in the river floodplain. Mathematical models describing vegetation growth in a short period exist in literature, but long-term modelling and validations are still lacking. In order to cover long-term vegetation growth modelling, a Dynamic Riparian Vegetation Model (DRIPVEM) was proposed. This paper highlights the existing modelling technique of DRIPVEM coupled with a Dynamic Herbaceous Model used to establish the interactive relationship of sediment grain sizes and riparian vegetation in the floodplain.

Abstract:

The objective of this study was to increase understanding of the processes structuring and controlling the species richness of riparian plant communities. In particular, I examined the unimodal relationship, found in many rivers, between plant species richness and location along the river corridor. The most important finding was that this pattern is dynamic and varies with time, most likely in response to large-scale flood disturbances. I also found that the sensitivity to flood disturbance varied with the environmental setting of the riparian reaches. Turbulent sections of the river retained high species richness, whereas tranquil reaches had significantly lower species richness in years following high and prolonged flooding, compared to a period without extreme flood events. Riparian soils along turbulent reaches are more resistant to oxygen depletion during floods, a factor which is likely to contribute to the maintenance of species richness.

The finding that the species richness pattern varied with time led me to ask which factors control plant diversity along riparian zones. I addressed this question by formulating three contrasting, although not mutually exclusive, hypotheses: (1) longitudinal patterns in riparian plant species richness are governed by local, river-related processes independent of the regional species richness, (2) riparian plant species richness is controlled by dispersal along the river, i.e., longitudinal control, and (3) the variation in riparian plant species richness mirrors variation in regional richness, i.e., lateral control. I found indications of all three types of control, although local factors seemed to fit most of the criteria. Riparian species richness was not significantly correlated to species richness in the surrounding upland valley. It was however significantly negatively correlated to soil pH, a local habitat factor of the reach. The fact that the species richness pattern varied in time, corresponding to the presence or absence of extreme flood events suggest that it is influenced by local disturbance regimes. The potential for control by longitudinal dispersal was found to be highest in the middle reaches of a river. Here, the similarity between upland and riparian vegetation was lowest, and invasibility (germination ability) was highest. Earlier work has shown that regulated rivers have an inverted species richness pattern compared to free-flowing rivers, with lowest species richness in the middle reaches. One potential mechanism behind this could be varying susceptibility to disturbance along the river. I tested this by experimentally disturbing the vegetation, applying the same level of disturbance along an entire free-flowing river. However, the response to experimental disturbance did not vary with location, likely because of a major flood disturbance preceding the experiment.

The present master's thesis, had as its main objective the application of a dynamic model of riparian habitats in a case study with pronounced mediterranean characteristics. he vegetation model used is based on the existence of water conditions (water height and distance to water) suitable for the development of each type of riparian vegetation in different stages of their development, modeling annually its space-time evolution. The rules underlying the model take into account the height of the flow, the shear stress and duration of flooding. The modeling of vegetation held in ArcGIS environment, bases on three general ohases: initial creation of landscape, simulation of temporal and spatial evolution of vegetation and the presentation of annual results.

ENGLISH ABSTRACT: Riparian vegetation communities that occur along perennial rivers are structured in lateral zones that run parallel to river flow. This dissertation investigated the structure of South African riparian vegetation communities along perennial, single-thread headwater streams. The central assumption was that lateral zones result from differential species’ responses to changing abiotic factors along a lateral gradient up the river bank. It was first necessary to establish the pattern of zones and whether this pattern occurs repetitively and predictably on different rivers in different biomes. Since the flow regime is considered to be the master variable that controls the occurrence of lateral zones, the link between flow as the major abiotic driver and the distribution of plants in zones was determined. Predictions were made with respect to how variable flow may influence phenological traits, particularly with respect to seed dispersal, and physiological tolerances to drying out and were tested. The existence of lateral zones at reference sites in the Western Cape of South Africa was explored and their vegetation characteristics were described. Plant distribution was related to bank slope, as defined by elevation and distance from the wetted channel edge during summer (dry season) low flow, indicating a direct link to river bank hydraulics. Whether or not the same zonation patterns occur in riparian communities in other parts of South Africa was explored next. The four zones described for Fynbos Riparian Vegetation were evident at all of the other rivers tested, despite major differences in geographic location, vegetation community type, climate and patterns of seasonal flow. The four lateral zones could be separated from each other using a combination of flood recurrence and inundation duration. Functional differences were investigated between three tree species that occur in Fynbos Riparian Vegetation. Functional differences were apparent with respect to timing of seed dispersal, growth in branch length versus girth and three physiological measures of tolerance to drying out; specific leaf area (cm2.g-1), wood density (g.cm-3) and levels of carbon isotopes (δ13C). In order to determine the impact of invasive alien plants and to monitor recovery after clearing, the physical rules devised to help delineate zones were used to locate lateral zones that had been obliterated after invasion and subsequent clearing. At the sites invaded by A. mearnsii plants, the zone delineations showed that invasion started in the lower dynamic zone, where adult and sapling A. mearnsii were most abundant. In un-invaded systems, this zone was the least densely vegetated of the four zones, the most varied in terms of inundation duration and the frequency of inter- and intra-annual floods, and was an area of active recruitment comprised mainly of recruiting seedlings and saplings. An understanding of the functional differences between lateral zones was a common thread at each riparian community that was linked to the annual frequency of inundation and the period, when inundated.
AFRIKAANSE OPSOMMING: Oewer plantegroei gemeenskappe wat langs standhoudende riviere voorkom is gestruktureer in laterale sones parallel met die rivier vloei. Hierdie verhandeling ondersoek die struktuur van Suid-Afrikaanse oewer plantegroei gemeenskappe langs standhoudende, enkelloop hoof strome. Die sentrale aanname was dat laterale sones vorm as gevolg van verskillende spesies se reaksie teenoor die verandering van abiotiese faktore teen 'n laterale gradiënt met die rivierbank op. Dit was eers nodig om die patroon van die gebiede vas te stel en uit te vind of hierdie patroon herhaaldelik en voorspelbaar binne verskillende riviere in verskillende biome voorkom. Aangesien die vloeiwyse beskou word as die hoof veranderlike wat die teenwoordigheid van laterale sones beheer, is die skakel tussen die vloei, as die belangrikste abiotiese bestuurder, en die verspreiding van plante in sones bepaal. Voorspellings is gemaak met betrekking tot hoe veranderlike vloei fenologiese eienskappe kan beïnvloed, veral met betrekking tot die saad verspreiding, en fisiologiese toleransie teen uitdroog, en is getoets. Die bestaan van laterale sones binne verwysings studie terreine in die Wes-Kaap van Suid- Afrika is ondersoek en hul plantegroei eienskappe is beskryf. Plant verspreiding was verwant aan bank helling, soos gedefinieer deur hoogte en afstand vanaf die nat kanaal rand gedurende somer (droë seisoen) lae vloei, en dui dus op 'n direkte skakel met die rivier bank hidroulika. Of dieselfde sonering patrone voorkom in oewer gemeenskappe in ander dele van Suid-Afrika is volgende verken. Die vier sones beskryf vir fynbos oewer plantegroei was duidelik by al die ander riviere wat ondersoek is, ten spyte van groot verskille in geografiese ligging, plantegroei gemeenskap tipe, klimaat en patrone van seisoenale vloei. Die vier laterale sones kan onderskei word van mekaar deur middel van 'n kombinasie van vloed herhaling en oorstroomde toestand duur. Funksionele verskille is ondersoek tussen drie boom spesies wat voorkom in Fynbos Oewer Plantegroei. Funksionele verskille was duidelik met betrekking tot tydsberekening van saad verspreiding, groei in tak lengte tenoor omtrek, en drie fisiologiese maatstawwe van verdraagsaamheid teenoor uitdroging; spesifieke blaar area (cm2.g-1), hout digtheid (g.cm-3) en vlakke van koolstof isotope (δ13C). Ten einde die impak van indringerplante te bepaal en die herstel na ontbossing te monitor is die fisiese reëls voorheen vasgestel om sones te help baken gebruik om laterale sones, wat vernietig is na indringing en die daaropvolgende ontbossing, te vind. Op die terreine wat deur A. mearnsii indringerplante binnegeval is, het die indeling van sones getoon dat die indringing begin het in die laer dinamiese sone, waar volwasse en klein A. mearnsii bome die volopste was. In stelsels wat nie binnegeval is deur indringerplante was hierdie sone die minste dig begroei van die vier sones, die mees verskillend in terme van oorstroomde toestand duur en die frekwensie van inter-en intra-jaarlikse vloede, en was 'n gebied van aktiewe werwing hoofsaaklik bestaande uit rekruut saailinge en boompies. 'n Begrip van die funksionele verskille tussen laterale sones was 'n algemene verskynsel by elke oewer gemeenskap wat gekoppel was aan die jaarlikse frekwensie van oorstroming en die oorstroomde toestand duur.

Abstract:
The relationship between photosynthesis and transpiration from riparian vegetation in a semi-arid region is the primary focus of interest in this study. An eddy covariance system was used to measure fluxes of energy, momentum, and carbon over an extended period which included a monsoon season and a subsequent prolonged dry period. The photosynthetic portion of the measured CO2 flux was obtained by subtracting the mean value of nighttime CO2 flux (respiration) from the daytime CO2 flux, and the resulting photosynthesis estimates were then compared with transpiration and other variables. Because the data revealed a somewhat complex relationship between photosynthesis and transpiration on both an hourly and a daily basis, a further analysis was made involving both the calculation of the canopy conductance and a 'stand alone' version of the Simple Biosphere (SiB2) Model. The results showed the assumed relationship between canopy photosynthesis and canopy conductance used in SiB2 is inconsistent with observations, however Monteith's suggestion that the ratio of the CO2 concentration inside leaves to that outside leaves is approximately constant, which leads to a linear relationship between canopy conductance and photosynthesis, is consistent with observations.

Abstract:
Land use practices over the last 200 years have dramatically altered the distribution and amount of riparian vegetation throughout many catchments in Australia. This has lead to a number of negative impacts including a decrease in water quality, an increase in sediment transport and a decrease in the quality of terrestrial and aquatic habitats. The task of restoring the functions of riparian zones is an enormous one and requires spatial and temporal prioritisation. An analysis of the existing and historical functions of riparian zones and their spatial distribution is a major aid to this process and will enable efficient use of remediation resources. The approach developed in this thesis combines remote sensing, field measurement and terrain analysis to describe the distribution of five riparian zone functions: sediment trapping, bank stabilization, denitrification, stream shading and large woody debris production throughout a large semi-arid catchment in central Queensland.

Abstract:
Increasingly, the importance of vegetation in influencing the structure and function of riparian zones has been recognised (e.g. Bendix and Hupp, 2000; Tabacchi et al., 2000). This thesis explores vegetation dispersal and establishment in the riparian zones of two contrasting river systems, with a focus upon Salicaceae. Dispersal, hydrochorous transport, deposition and establishment of vegetation along the River Frome (UK), was investigated over one year. The study demonstrated the importance of hydrochory for dispersing propagules to new environments and for promoting diversity within the riparian zone. The role of hydrochory changed seasonally and with the hydrological regime, highlighting the importance of high flows for structuring and creating diversity in riverbank vegetation.

Abstract:
Models of climate change predict that temperature will increase during the 21th century and the largest warming will take place at high northern latitudes. In addition to warming, predictions for northern Europe include increased annual precipitation and a higher proportion of the precipitation during winter falling as rain instead of snow. These changes will substantially alter the hydrology of rivers and streams and change the conditions for riverine communities. The warming is also expected to result in species adjusting their geographic ranges to stay within their climatic tolerances. Riparian zones and wetlands are areas where excess water determines the community composition. It is therefore likely that these systems will be highly responsive to alterations in precipitation and temperature patterns. In this thesis we have tested the predicted responses of riparian vegetation to climate-driven hydrologic change with a six year long transplant experiment (I). Turfs of vegetation were moved to a new elevation with shorter or longer flood durations. The results demonstrate that riparian species will respond to hydrologic changes, and that without rare events such as unusually large floods or droughts, full adjustment to the new hydrological regime may take at least 10 years. Moreover, we quantified potential effects of a changed hydrology on riparian plant species richness (II) and individual species responses (III) under different climate scenarios along the Vindel River in northern Sweden. Despite relatively small changes in hydrology, the results imply that many species will become less frequent than today, with stochastic extinctions along some reaches. Climate change may threaten riparian vegetation along some of the last pristine or near-natural river ecosystems in Europe. More extensive loss of species than predicted for the Vindel River is expected along rivers in the southern boreal zone, where snow-melt fed hydrographs are expected to be largely replaced by rain-fed ones. With a seed sowing experiment, we tested the differences in invasibility between open wetlands, forested wetlands and riparian zones (IV). All six species introduced were able to germinate and survive in all habitats and disturbance levels, indicating that the tested wetlands are generally invisible. Germination was highest in open wetlands and riparian zones. Increasing seed sowing density increased invasion success, but the disturbance treatments had little effect. The fact that seeds germinated and survived for 2 to 3 years in all wetland habitats indicates that wetland species with sufficiently high dispersal capacity and propagule pressure would be able to germinate and establish here in their respective wetland type. Our results clearly demonstrate that a changed climate will result in substantial changes to functioning, structure and diversity of boreal wetland and riparian ecosystems. To preserve species rich habitats still unaffected by dams and other human stressors, additional protection and management actions may have to be considered.
