“…Riparian habitats are an interface between terrestrial and aquatic ecosystems along inland watercourses [1] and provide a series of ecological services important for the balance of the environments with which they come into contact (buffer effect against the loss of nutrients, purification of drainage water, anti-erosion action, consolidation of the banks, etc.) [2,3]. Riparian habitats develop on gravelly-sandy riverbeds with torrential regimes, with significant variations of the water table level during the year, and on alluvial soils are often flooded, features which often may hamper the evolution of the cenosis towards mature communities [4].…”

Riparian habitats provide a series of ecological services vital for the balance of the environment, and are niches and resources for a wide variety of species. Monitoring riparian environments at the intra-habitat level is crucial for assessing and preserving their conservation status, although it is challenging due to their landscape complexity. Unmanned aerial vehicles (UAV) and multi-spectral optical sensors can be used for very high resolution (VHR) monitoring in terms of spectral, spatial, and temporal resolutions. In this contribution, the vegetation species of the riparian habitat (91E0*, 3240 of Natura 2000 network) of North-West Italy were mapped at individual tree (ITD) level using machine learning and a multi-temporal phenology-based approach. Three UAV flights were conducted at the phenological-relevant time of the year (epochs). The data were analyzed using a structure from motion (SfM) approach. The resulting orthomosaics were segmented and classified using a random forest (RF) algorithm. The training dataset was composed of field-collected data, and was oversampled to reduce the effects of unbalancing and size. Three-hundred features were computed considering spectral, textural, and geometric information. Finally, the RF model was cross-validated (leave-one-out). This model was applied to eight scenarios that differed in temporal resolution to assess the role of multi-temporality over the UAV’s VHR optical data. Results showed better performances in multi-epoch phenology-based classification than single-epochs ones, with 0.71 overall accuracy compared to 0.61. Some classes, such as Pinus sylvestris and Betula pendula, are remarkably influenced by the phenology-based multi-temporality: the F1-score increased by 0.3 points by considering three epochs instead of two.

“…Riparian zones represent transitional areas occurring between land and freshwater ecosystems, that provide many ecosystem functions and services related to water quality, microclimate regulation, structural habitat for wildlife, energy base for the food web, and bank stability (Naiman et al, 2005). Particularly, riparian plants represent a primary energy source for in-stream consumers, especially in headwater sections, having a strong influence on the structure of freshwater communities (e.g.…”

“…Riparian vegetation performs important ecological functions such as provision of habitat and food for many species, regulation of shade and water temperature, control of nutrient and sediment input into streams, provision of corridors for the movement of biota, and stabilization of riverbanks (Naiman & Décamps 1997, Ewel et al 2001, González del Tánago & García de Jalón 2007. In addition, riparian zones provide spaces for recreational purposes (Naiman et al 2005). While riparian environments are among the most diverse and complex biophysical ecosystems (Naiman et al 1993), they are one of the most disturbed by land use change (Charron et al 2008).…”

“…At the local level, vegetation is one of the most susceptible elements influenced by management and land use practices (Van de Kamp et al 2013) and, among riparian plant communities, woody vegetation exhibits the strongest relationship with physical factors (Lyon & Gross 2005). Alterations in the vegetation community can occur due to introduction of exotic species (Naiman et al 2005), or through decline in species diversity and canopy coverage (Moffatt et al 2004).…”

Influence of land use on the condition of the riparian zone along an urban-rural gradient in the Sabinal River, Mexico

Background: Riparian vegetation is strongly influenced by the surrounding land use. While it is known that urbanization processes can affect plant species composition and the ecological condition of the riparian zone, the specific responses require a fuller understanding.Hypothesis: The quality of riparian zones is inversely related to the degree of urbanization of adjacent areas, and that land uses that provide forest cover ensure a less degraded condition and greater diversity of species.Study site and year of study: Sabinal River basin, Chiapas, Mexico, 2015.Methods: Measures of the Riparian Quality Index (RQI) and plant species composition were compared among three different land use conditions (secondary forest, grasslands and crops, and human settlements). Results: Riparian zones adjacent to secondary forest showed higher RQI than those next to grasslands and crops and human settlements. Riparian zones within secondary forest also had a higher woody species richness and better substrate condition, whereas reaches adjacent to human settlements appeared paved and eroded, exhibiting soil compaction. Species richness and diversity were positively correlated to the RQI and were greater in riparian zones adjacent to secondary forest than in those next to human settlements.Conclusions: While grazing and cultivation affect the riparian zone, expansion of urban areas has a greater impact by reducing woody species richness and diversity, altering species composition and favoring soil compaction and bank erosion, which results in reduced riparian quality.
