“…However, the opposite pattern has been reported for French poplar plantations [21,22,65]. On the other hand, higher species richness was observed in plantations where strip tillage had been carried out for site preparation in comparison with full-area ploughing [24]. Finally, we did not find any differences in species richness according to site quality, in contrast to previously observed differences in Populus tremuloides Michx.…”

Abstract:Riparian vegetation, which performs many key ecological functions, has been modified or lost at an alarming rate during the past century as a result of human activity. The aims of this study are (a) to investigate the effects of poplar plantations on plant diversity in riparian zones; and (b) to estimate the ecological implications of extending cover by poplar plantations. For this purpose, we assessed species richness, habitat indicator species and functional diversity based on Grime's C-S-R strategies. We used non-metric multidimensional scaling to examine the role of environmental factors such as soil properties, forest structure and management. Disturbance, in particular the frequency of harrowing, led to a decline in species richness and modified the indicator species and functional diversity by favoring Ruderal (R) species at the expense Stress-Tolerant (S) and Competitor (C) species, which are better suited to riparian forest conditions. Poplar plantations should not be used as surrogates for riparian forests, and minimizing harrowing in poplar plantations promotes vascular plant diversity. Furthermore, reintroduction of herbs, ferns and geophytes with a high conservation value and low seed dispersal capacity is advisable from the sixth year after establishment, once harrowing for weed control has been completed.

“…We included both direct and indirect comparisons in these studies in order to not lose valuable knowledge regarding the capacity of plantations to serve as restoration tools. While the intermediate land use and land use history will clearly influence biodiversity outcomes (Ito et al 2004;Lee et al 2005;Brunet 2007;Soo et al 2009), these cases were included in order to not lose information and to be able to compare indirect and direct comparisons. Those transitions involving direct comparisons and those with an intermediate land use are clearly indicated in Appendix 1 (see Electronic supplementary material).…”

“…Other studies, however, have found high levels of species richness in younger plantations, but have primarily attributed this to an increase in light-demanding ruderal and often exotic species, with native forest species increasing with plantation age (Ito et al 2004;Nagaike et al 2006;Soo et al 2009). On the other hand, plantations established on natural or semi-natural shrublands and grasslands would be expected to have a greater negative effect on native species with age, increasing canopy cover, and with multiple rotations (Wallace and Good 1995;Maccherini and De Dominicis 2003;O'Connor 2005).…”

Does plantation forestry restore biodiversity or create green deserts? A synthesis of the effects of land-use transitions on plant species richness

2010

Plantations are established for a variety of reasons including wood production, soil and water conservation, and more recently, carbon sequestration. The effect of this growing land-use change on biodiversity, however, is poorly understood and considerable debate exists as to whether plantations are 'green deserts' or valuable habitat for indigenous flora and fauna. This paper synthesizes peer-reviewed articles that provide quantitative data on plant species richness in plantations and paired land uses, most often representative of preplantation land cover. The results of this synthesis suggest that the value of plantations for biodiversity varies considerably depending on whether the original land cover is grassland, shrubland, primary forest, secondary forest, or degraded or exotic pasture, and whether native or exotic tree species are planted. The results of this study suggest that plantations are most likely to contribute to biodiversity when established on degraded lands rather than replacing natural ecosystems, such as forests, grasslands, and shrublands, and when indigenous tree species are used rather than exotic species. These findings can help guide afforestation and reforestation programs, including those aimed at increasing terrestrial carbon sequestration.

“…This is supported by the apparent lack of treatment effect on soil properties (not statistically tested). In a study investigating floristic diversity in 7-to-8-year-old hybrid poplar plantations established on abandoned agricultural sites of Estonia and submitted to various site preparation methods, Soo et al (2009) also reported that plant composition was dominated by 'competitive' species.…”

We present a case study in which we assessed the effects of a severe soil perturbation on the plant community and soil variables in young hybrid poplar (Populus sp.) plantations of southern Québec (Canada). Our overall goal was to test if soil perturbation and planting fast-growing species could promote the reestablishment of a relatively diverse plant community. A chronosequence that included three plantations (4, 8, and 12-year old) established after soil scarification, paired with three natural stands representative of the local temperate mixedwood forest comprising both pioneer and late-successional tree species, was implemented. Vegetation surveys and soil collection were performed in 2012 and species traits were provided by the Traits Of Plants In Canada and TRY databases. Principal response curve analyses showed species and functional trait divergence between treated and natural stands at ages 4 and 8, but that those divergences were less at age 12. Species and trait convergences were slower in the scarification furrows than in the scarification berms (mounds between furrows). However, severe site preparation did not appear to affect soil variables on the study sites. Our results suggest that even following severe site preparation, gradual recovery of species and trait composition similar to that of natural stands appears possible in the long term, mainly through fast canopy development by hybrid poplar. However, organic material export and soil erosion risks associated with this type of site preparation need to be evaluated. ARTICLE HISTORY
