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.

Dispersal ability is known to limit the colonization by many fenland species onto restored habitat but factors determining colonization by wetland invertebrates onto restored fenland have not been previously examined. We used mark-release-recapture and harmonic radar tracking coupled with genetic analysis (ISSR-PCR, inter-simple sequence repeat—polymerase chain reaction) to assess the population structure and colonization of a brachypterous wetland carabid (Carabus granulatus) onto restored fenl...

One of the primary goals of research on bioindicators is to identifyspecies or other taxonomic units that would reliably indicate disturbances inthe environment, and reflect the responses of other species or the overallbiodiversity. However, there is no perfect bioindicator and selecting the mostsuitable one depends to a great extent on the goal of the survey. In this paperwe examine the suitability of carabids as bioindicators. Carabids are frequentlyused to indicate habitat alteration. They ha...

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...

Summary Grasslands restoration is a key management tool contributing to the long-term maintenance of insect populations, providing functional connectivity and mitigating against extinction debt across landscapes. As knowledge of grassland insect communities is limited, the lag between the initiation of restoration and the ability of these new habitats to contribute to the successful enhancement of native biodiversity is unclear. Using two long term data sets from the same restoration experiment,...

1. Species-rich lowland hay meadows are of conservation importance for both plants and invertebrates; however, they have declined in area across Europe as a result of conversion to other land uses and management intensification. The re-creation of these grasslands on ex-arable land provides a valuable approach to increasing the extent and conservation value of this threatened habitat. 2. Over a 3-year period a replicated block design was used to test whether introducing seeds promoted the re-cre...

Abstract The rate of recovery of invertebrate communities following habitat restoration has received little attention, despite the importance of invertebrates in ecosystem dynamics. In experimental trials in a mined peat bog in New Zealand, we compared the short-term rate of beetle community re-assembly at sites restored using management techniques varying in cost and effort to implement, and subsequently examined the long-term rate of beetle community convergence towards the ‘target’ community ...

A study of beetle (Coleoptera) communities was conducted in three revegetated sites of different ages (5, 17, and 100 years) and in a remnant coastal habitat dominated by Muehlenbeckia complexa (a liane) on Matiu-Somes Island, Wellington Harbor, New Zealand. The 25-ha island has had a 110-year history as a pastoral agricultural quarantine station. Beetles were surveyed from May 1997 to April 1998 using pitfall traps. We collected a total of 3,430 adult beetles from 78 beetle species belonging to...

The conservation of biological diversity requires an integrated approach covering the ecological demands of a multitude of species. Integration may be achieved by focusing on a careful selection of target species, which is rare in practice. Calcareous grasslands offer a case in point. Although they harbour a high diversity of both plant and insect species, in management the emphasis is placed on the flora. This results in an underestimation of, notably, the importance of structural heterogeneity...

Ecological restoration has been identified as one of the possible ways to replace biodiversity loss. While ecological engineering methods can successfully restore some ecosystem attributes, restoration is generally incomplete, mainly due to lack of target species propagule dispersal, unsuitable abiotic conditions and negative biotic interactions, especially after intensive cultivation. How best to restore reference ecosystems is therefore a vital research objective, not only on a small experimen...

Habitat restoration has become an important part of biodiversity conservation in the face of extensive habitat loss and fragmentation, especially in agricultural landscapes. Study of invertebrates such as beetles (Coleoptera) may be important to assess the effectiveness of restoration techniques in maintaining native fauna, because they provide a variety of trophic roles and ecosystem services. In this study we examined the conservation value for beetles of revegetation in linear strips and alon...

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...
