Abstract
Given that biological conservation cannot prevent the full range of negative impacts on biodiversity, ecological restoration is nowadays commonly acknowledged as a necessary tool for conservation purposes. Here, we report on an ecological rehabilitation project in the La Crau area (south-eastern France), beginning in 2009 when a former industrial orchard (357 ha) was rehabilitated into a Mediterranean rangeland. We assessed the effect of ecological rehabilitation and different additional restoration treatments on beetle assemblages. Seven treatments were considered: the reference steppe, the rehabilitated treatment alone, three additional experimental restoration treatments (soil transfer; nurse species seeding and hay transfer), the control and the edge between the steppe and the former industrial orchard area. All beetle families were considered. Beetles were sampled with pitfall traps for 3 years (2011–2013). Our major finding was a positive effect of soil transfer and nurse species seeding treatments, which promote the characteristic beetle composition of the reference steppe. Nevertheless, strong differences remain between the steppe and the various assessed treatments in terms of composition. Long-term monitoring should therefore now focus on particular beetle indicator species that could reflect the response of the overall characteristic beetle assemblage of the reference steppe.

Ecosystem restoration provides unique opportunities to study community dynamics under succession and can reveal how consumer communities re-assemble and respond to successional changes. Studying community dynamics from both taxonomic and functional trait perspectives also may provide more robust assessments of restoration progress or success and allow cross-system comparisons. We studied ground beetle (Coleoptera: Carabidae) communities for three years in a restored grassland chronosequence with...

Abstract Insects are among the most diverse and abundant organisms on Earth, and they play a major role in ecosystem functioning. To protect them from decline, some conservation measures have been put in place, based primarily on threatened species lists. This is the case in Europe, where 123 of the 105,000 known European insect species are currently protected. Yet how were these few species selected? Are those species representative of the European entomofauna? Is it possible for a conservation...

Global declines in insects have sparked wide interest among scientists, politicians, and the general public. Loss of insect diversity and abundance is expected to provoke cascading effects on food webs and to jeopardize ecosystem services. Our understanding of the extent and underlying causes of this decline is based on the abundance of single species or taxonomic groups only, rather than changes in insect biomass which is more relevant for ecological functioning. Here, we used a standardized pr...

Coastal dunes are fragile dynamic environments characterised by low productivity and high levels of bare and shifting sands. They are highly threatened by urbanisation and human development. The dunes in Nizzanim Dunes Nature Reserve, Israel, have additionally incurred shrub encroachment following exclusion of grazing and wood extraction from the area. The temporal changes over the last few decades have been monitored in the Nizzanim Long-Term Ecological Research project and are reflected by spa...

There is increasing recognition that community assembly theory can offer valuable insights for ecological restoration. We studied community assembly processes following tropical forest restoration efforts, using dung beetles (Scarabaeinae) as a focal taxon to investigate taxonomic and functional patterns of biodiversity recovery. We evaluated the relative importance of the local environment (i.e., canopy cover, understory cover, tree basal area, and soil texture), landscape context (i.e., habita...

A last resort means to restoring a severely degraded ecosystem can involve soil transfer, especially when destruction of an undegraded system has been previously independently planned. We measured the impact of different soil transfer treatments that varied in vertical and orderly reconstitution of the main soil horizons on the microbial activity and organic matter composition during restoration of a Haplic Cambisol in a steppe ecosystem. There were differences between the topsoil of the referen...

Abstract Of the many techniques tested to date to rehabilitate degraded ecosystems, topsoil transfer appears to offer the best results. However, this method is recent, and results achieved in the short term (months to years) may not provide a sound indication of long-term vegetation reestablishment. In the plain of La Crau in southeastern France, many dry alluvial quarries were exploited in the 1970s–1980s and are nearly all now abandoned. Various topsoil transfers were performed when operations...

There is growing evidence of restoration success for wetland plant communities. However, little research has been done on the associated invertebrate community. We test whether restoring plant communities after peat extraction is sufficient for restoring the taxonomic and functional composition of beetle communities. We monitored taxonomic and trait-based community metrics for beetle assemblages on restoration islands that were up to 13 years old and compared these with the adjacent “target” und...

The aim of the study was to assess the effects of fen rewetting on carabid beetle and vascular plant assemblages within riverine fens along the river Peene in north-eastern Germany. Drained (silage grassland), rewetted (restored formerly drained silage grassland), and near-natural (fairly pristine) stands were compared. Eighty-four beetle species (7,267 individuals) and 135 plant species were recorded. The richness of vascular plant species and the number of endangered species were highest on ne...

Conservation biology and restoration ecology share a common interest in maintaining or enhancing populations, communities, and ecosystems. Much could be gained by more closely integrating the disciplines, but several challenges stand in the way. Goals differ, reflecting different origins and agendas. Because resources are insufficient to meet all needs, priorities must be established. Rapid environmental changes create uncertainties that compromise goals and priorities. To realize the benefits o...

Le premier site naturel de compensation francais a ete inaugure le 11 mai 2009 sur le site d’un verger abandonne dans la plaine de Crau (Bouches-du-Rhone, France). Cette operation avait notamment pour objectif d’experimenter le premier mecanisme d’offre de compensation francais via la rehabilitation d’une vegetation herbacee permettant le retour des oiseaux steppiques emblematiques de cet espace. Impliques dans le comite local de pilotage, des ecologues ont conseille les techniques de rehabilita...
