“…The main land use in the area is semi-natural (dominant shrubby landscape) and agriculture (mainly drylands, rice fields, apricot and peach trees), with urban areas being scarce (<2%; Figure 1). Native riparian vegetation in the area was characterized by 92A0 and 92D0 habitats (Habitat Directive 92/43/CEE), showing a mixture of European and Ibero-African flora (Salix spp., Fraxinus angustifolia, Populus spp., Tamarix spp., Nerium oleander), which constitutes a distinctive occurrence within the Iberian Peninsula [15,54]. Although historic detailed information about the evolution of invasion in the study area is lacking, native habitats 92A0 and 92D0 have been progressively displaced by A. donax, which already occupies nearly a 40% of the riparian zone within the studied area according to the preliminary evaluation carried out to draft the project (Figure 1).…”

Invasive species are among the top five causes of biodiversity loss worldwide. Arundo donax has progressively colonized the riparian zones of Mediterranean rivers with detrimental effects on terrestrial and aquatic biodiversity, being catalogued as one of the 100 worst invasive species. In order to control this invasive species and restore native riparian vegetation, different methods have been traditionally used, depending on the environmental, economic and social context. Here, the effect of repeated above-ground removal of A. donax on aquatic and terrestrial communities was assessed by testing two different frequencies of mowing (monthly-intensive and quarterly-extensive), combined with the plantation of native species. Specifically, it was evaluated if riparian vegetation, birds and aquatic macroinvertebrates showed significant responses throughout time and between restoration treatments based on 4-year annual biomonitoring data (2015–2018). Changes in taxonomic diversity and ecological quality indices for the different biological communities were tested using mixed-effect models (LMEs). Similarly, comparisons between restored and reference sites were also performed. LMEs were also applied to assess how riparian variables were related to bird and aquatic macroinvertebrate indices. NMDS and MGLM-Mvabund analyses were performed to detect significant post-treatment differences in taxa composition compared to the initial state and reference sites. During this short-term assessment, increases in riparian and aquatic macroinvertebrate richness and quality indices were found, as well as significant decreases in A. donax height, density and cover, without significant differences between restoration treatments. However, differential effects between extensive (positive-neutral effect) and intensive treatments (neutral-negative effect) were detected for bird richness, density and abundance. After three years of restoration actions, restored sites are still far from reference values in terms of taxa composition, species richness and ecological quality, especially for riparian vegetation and birds. Given the high cost and the great efforts required for restoration, extensive repeated mowing, together with native species plantation, are only recommended on river reaches not fully invaded by A. donax and with a high ecological interest.

“…Los estudios de impacto ambiental generados por disturbios antrópicos, tradicionalmente se enfocan en medidas estructurales basadas en la taxonomía (diversidad específica). Las aproximaciones taxonómicas, así como el estudio de los parámetros comunitarios (i.e., riqueza, equitatividad y diversidad) fueron muy utilizadas para evaluar el estado ecológico de los ecosistemas y detectar las respuestas de las comunidades biológicas al estrés y al impacto ambiental (Bruno 2016). Sin embargo, en los últimos años se ha prestado mayor atención a los cambios en la diversidad que puede modificar potencialmente el funcionamiento del ecosistema (Loreau et al 2001;Hawkins et al 2009), dándole así importancia a los atributos funcionales de las especies (diversidad funcional) (Loreau et al 2001;Hooper et al 2005;Elliot and Quintino 2007).…”
