“…(Hartley 2002;Zerbe 2002;Lindenmayer and Hobbs 2004;Ginsberg 2006;Paritsis and Aizen 2007). It has been argued that plantation may protect natural biodiversity indirectly by enabling greater wood production from smaller, intensively managed areas, thus sparing remaining natural forests harvesting pressure (Carnus et al 2006).…”

Pourbabaei H, Asgari F, Reif A, Abedi R. 2012. Effect of plantations on plant species diversity in the Darabkola, Mazandaran Province,. In this study, the effect of plantations on plant species diversity was investigated in Darabkola, Mazandaran province, north of Iran. To conduct the study, a natural mixed forest, a broad-leaved plantation (Alnus subcordata-Acer velutinum) and a coniferous plantation (Cupressus sempervirens var. horizontalis-Pinus brutia) were selected. 35 sampling plots were taken in systematic random method in each area. Data analysis was carried out using Simpson, Hill's N 2 , Shannon-Wiener and Mc Arthur's N 1 diversity indices, Smith and Wilson evenness index and species richness. Results revealed that there were 32 plant species in natural forest and 30 plant species were found in each plantation. Rosaceae and Lamiaceae were the main families in the studied areas. Diversity and evenness indices of all vegetation layers had the most values in the natural forest. Richness of woody plants had the highest value in the natural forest, while herbaceous richness was the highest in coniferous plantation. Mc Arthur's N1 had the highest value among diversity indices and followed by Hill's N 2 , Shannon-Wiener and Simpson indices, respectively. In addition, results showed that there were significant differences among diversity, evenness and richness indices in all vegetation layers in the three studied areas.

“…Here there are relatively few forest specialists compared with other parts of Europe, and forests are inhabited mainly by generalist species adapted to living in a range of habitat types (Mitchell 2006;Fuller et al 2007;Kelly 2008). Previous studies that used meta-analysis, which rely on data collected during separate studies, to investigate species richness across a number of taxonomic groups have found that species dependent on forests, such as bryophytes and saproxylic beetles are more negatively affected by forest management practices than more generalist species (Paillet et al 2010;Stephens and Wagner 2007;Paritsis and Aizen 2008).…”

“…The potential for these plantation forests to provide habitat for plant and animal species is a key component of sustainable forest management (SFM) (MCPFE 2011;Lindenmayer et al 2000). SFM one of the foremost tools for achieving compatibility between forest industries and the provision of ecosystem services, including the conservation of forest biodiversity (Paritsis and Aizen 2008;Hartmann et al 2010). The objectives of SFM in a landscape can only be realised when its objectives are based on an understanding of the ecology of existing woodlands.…”

“…While natural forests represent some of the most biologically diverse ecosystems in the world, including more than half of all terrestrial species (MEA 2005;FAO 2012), the highly managed nature of plantation forests means they may support less native biodiversity than naturally occurring forests (Hunter 1999;Lindenmayer and Hobbs 2004;Stephens and Wagner 2007;Paritsis and Aizen 2008). However, in countries where the extent of naturally occurring forests is limited, plantation forests may provide habitat for forest associated species and enhance overall landscape biodiversity, (Stephens and Wagner 2007;Brockerhoff et al 2008;Pawson et al 2008;Sweeney et al 2010;Coote et al 2012).…”

“…The response of species diversity to commercial plantation forests varies across taxonomic groups, and much of the evidence for this variation comes from meta-analyses of independent studies which consider individual taxa separately (Paillet et al 2010;Paritsis and Aizen 2008). Very few studies have used empirical data to investigate the importance of plantation forests for more than one taxon simultaneously.…”

The value of plantation forests for plant, invertebrate and bird diversity and the potential for cross-taxon surrogacy

As the area of plantation forest expands worldwide and natural, unmanaged forests decline there is much interest in the potential for planted forests to provide habitat for biodiversity. In regions where little semi-natural woodland remains, the biodiversity supported by forest plantations, typically non-native conifers, may be particularly important. Few studies provide detailed comparisons between the species diversity of native woodlands which are being depleted and non-native plantation forests, which are now expanding, based on data collected from multiple taxa in the same study sites. Here we compare the species diversity and community composition of plants, invertebrates and birds in Sitka spruce-(Picea sitchensis-) dominated and Norway spruce-(Picea abies-) dominated plantations, which have expanded significantly in recent decades in the study area in Ireland, with that of oak-and ash-dominated semi-natural woodlands in the same area. The results show that species richness in spruce plantations can be as high as seminatural woodlands, but that the two forest types support different assemblages of species. In areas where non-native conifer plantations are the principle forest type, their role in the provision of habitat for biodiversity conservation should not be overlooked. Appropriate management should target the introduction of semi-natural woodland characteristics, and on the extension of existing semi-natural woodlands to maintain and enhance forest species diversity. Our data show 2 that although some relatively easily surveyed groups, such as vascular plants and birds, were congruent with many of the other taxa when looking across all study sites, the similarities in response were not strong enough to warrant use of these taxa as surrogates of the others. In order to capture a wide range of biotic variation, assessments of forest biodiversity should either encompass several taxonomic groups, or rely on the use of indicators of diversity that are not species based.

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species’ threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project – and avert – future declines. We describe and assess a new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. The database contains more than 1% of the total number of all species described, and more than 1% of the described species within many taxonomic groups – including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems – http://www.predicts.org.uk). We make site-level summary data available alongside this article. The full database will be publicly available in 2015.
