“…De forma natural estas morfologías erosivas son estabilizadas mediante recolonización en sus estadios erosivos incipientes (Martínez, Hesp y Gallego-Fernández, 2011). En sistemas con elevados índices de erosión, se opta por la revegetación artificial para acelerar el proceso de sellado, con el objeto de recuperar la cubierta vegetal del frente dunar.…”

En las últimas décadas, se han aplicado a lo largo del litoral del estado español diferentes técnicas de gestión litoral con el fin de restaurar, mantener y proteger los sistemas playa-duna. Estas técnicas se han basado en la emulación artificial de los procesos naturales que favorecen la recuperación del sistema, mientras en otras se ha basado en la instalación de servicios que evitan la frecuentación y pisoteo de los sistemas dunares. La falta de criterios geomorfológicos en algunas actuaciones realizadas en las islas Baleares han generado y agravado procesos erosivos sobre aquellos que se pretendían recuperar, o bien se han fijado de forma artificial sistemas dinámicos. Este trabajo ejemplifica algunas técnicas aplicadas sin criterios geomorfológicos sobre sistemas dunares.

“…In terms of restoration methods, Lithgow et al [183] noted that there is no best way to restore a dune. The formation of dunes could be accomplished through beach nourishment, by providing the necessary sand volume and space for the dunes to develop, however in this case, maintenance is necessary for the preservation of dune integrity and time is needed for dune species to colonize [187]. However, the restoration of vegetation and morphology can last up to ten years [188] and be expensive.…”

Multifaceted Impacts of Sustainable Land Management in Drylands: A Review

et al. 2016

Biophysical restoration or rehabilitation measures of land have demonstrated to be effective in many scientific projects and small-scale environmental experiments. However circumstances such as poverty, weak policies, or inefficient scientific knowledge transmission can hinder the effective upscaling of land restoration and the long term maintenance of proven sustainable use of soil and water. This may be especially worrisome in lands with harsh environmental conditions. This review covers recent efforts in landscape restoration and rehabilitation with a functional perspective aiming to simultaneously achieve ecosystem sustainability, economic efficiency, and social wellbeing. Water management and rehabilitation of ecosystem services in croplands, rangelands, forests, and coastlands are reviewed. The joint analysis of such diverse ecosystems provides a wide perspective to determine: (i) multifaceted impacts on biophysical and socio-economic factors; and (ii) elements influencing effective upscaling of sustainable land management practices. One conclusion can be highlighted: voluntary adoption is based on different pillars, i.e. external material and economic support, and spread of success information at the local scale to demonstrate the multidimensional benefits of sustainable land management. For the successful upscaling of land management, more attention must be paid to the social system from the first involvement stage, up to the long term maintenance.

“…The anthropogenic stabilization of dunes has been identified as one of the main threats to the coastal ecosystems around the world (Martínez et al 2013). Management techniques include planting herbaceous or woody species tolerant to coastal dune conditions to prevent dune erosion and to stabilize blowing transgressive sand sheets (Pye 1983).…”

Sand stabilization by human plantation is generally considered as one of the most influential factors in biodiversity loss of coastal dune. Frequently, the environmental impact occurs beyond the initial plantation areas due to some planted species are capable to expand to the surrounding dune areas due to sometimes these species exhibiting invasive behavior. Assessing how the spatial and temporal colonization and spread of a shrub species takes place is an arduous task as the initial establishment is influenced by several factors. An understanding of this could be of great importance to the accurate prediction of the course of invasions and establish management plans. In this study, we quantify and analyze the spatio-temporal expansion patterns of the shrub Retama monosperma in a coastal dune landscape. In conjunction with measurements of plant spatial distribution, maturity and dimensions, we use an age-analysis approach to analyze the age structure of the colonizing population and the characteristics of the spread of the R. monosperma population in the early end of a sand spit formed over the last 33 years. The age structure of the dune population suggests that recruitment has increased continuously over time as the population has increased. We found significant differences between age and diameter size structures of dune ridge populations due to their different colonization stages and, in particular, to the environmental conditions. The presence of long-distance dispersers is essential for the spread of R. monosperma in this fragmented landscape. Population expansion is achieved by means of a coupled pattern of radiating wave fronts and the continuous establishment of multiple Bnascent foci^on ridges, which then expand and coalesce. R. monosperma displays lag-phase behavior in the early stages of colonization.
