“…On some study sites the invasive or naturalized reed canary grass (Phalaris arundinacea) formed dense, monotypic mats which impede further succession to the forest woodland. This reed has proliferated along the flow-stabilized lower Kootenai River and especially at silted backwaters, former side channels and wetlands (Egger et al, 2013). Under certain conditions, the shrub phase can directly follow the pioneer phase to provide the woodland series (Egger et al, 2013).…”

Under certain conditions, the shrub phase can directly follow the pioneer phase to provide the woodland series (Egger et al, 2013). Succession to the cottonwood shrub community can take 5e15 years after a pioneer phase, depending on the disturbance intensity.…”

“…Transition stage I). The classification of succession types was derived from Naiman et al (2005) and especially Egger et al (2013), and included natural primary ( PS ) and secondary successional ( SS ) pathways. Successional phases included: initial phase (IP), pioneer (PP), herb (HP), shrub (SP PS , SP SS ), early successional woodland (ESW PS , ESW SS ), established forest (EFP PS , EFP SS ), and mature (MS) phases.…”

“…However, extended inundation produces root anoxia and mortality (Glenz et al, 2006). Ultimately, vegetation colonization, succession and mortality are the result of interrelated and somewhat antagonistic disturbance and resistance gradients (Egger et al, 2013). The interplay between these opposing drivers and their co-evolutionary development was defined by Corenblit et al (2007) as the 'fluvial biogeomorphic succession' concept of riparian landforms and vegetation.…”

“…While Junk et al (1989) consider flood pulse as the driving force in determining riverfloodplain systems' equilibrium, Tockner et al (2000) also stress the ecological importance of expansion-contraction events below bankfull flooding (flow pulses). Moreover, fluvial hydrodynamics play an important role during all stages of plant life from seed dispersal to colonisation, recruitment, growth, succession and finally mortality (Crouzy et al 2013;Egger et al 2013;Solari et al 2015).…”

Exploring the key drivers of riparian woodland successional pathways across three European river reaches

International audienceClimate change and river regulation are negatively impacting riparian vegetation. To evaluate these impacts, process‐based models are preferred over data‐driven approaches. However, they require extensive knowledge about ecohydrological processes. To facilitate the implementation of such process‐based models, the key drivers of riparian woodland successional pathways across three river reaches, in Austria, Portugal, and Spain, were explored, employing two complementary approaches. The principal component analyses highlighted the importance of the physical gradients determining the placement of the succession phases within the riparian and floodplain zones. The generalized additive models revealed that the initial and pioneer succession phases, characteristic of the colonization stage, appeared in areas highly morphodynamic, close in height and distance to the water table, and with coarse substrate, whereas elder phases within the transitional and mature stages showed incremental differences, occupying less dynamic areas with finer substrate. The Austrian site fitted well the current successional theory (elder phases appearing sequentially further up and distant), but at the Portuguese site, the tolerance of the riparian species to drought and flash flood events governed their placement. Finally, at the Spanish site, the patchy distribution of the elder phases was the remnants of formative events that reshaped the river channel. These results highlight the complex relationships between flow regime, channel morphology, and riparian vegetation. The use of succession phases, which rely on the sequential evolution of riparian vegetation as a response to different drivers, may be potentially better reproducible, within numerical process‐based models, and transferable to other geographical regions
