Titre : Characterisation of Underground Organs as a Basis for Estimating Rhizome Resprouting Potential: The Case Study of Two Invasive Reynoutria Taxa (Polygonaceae) Type de document : Numérique Auteurs : Antoine Jousson ; Marco Conedera ; Guido Maspoli ; Gianni Boris Pezzatti Année de publication : 2026 Article en page(s) : e70044 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Reynoutria japonica Houtt., 1777 Résumé : The Japanese knotweeds (Reynoutria japonica complex; Polygonaceae) are characterised by a highly efficient vegetative propagation. Their resprouting capacity is associated with rhizomes, whose nodal structure distinguishes them from non-regenerative roots. Knowing the distribution of both organ types is therefore a key prerequisite for eradication measures. The present study aimed to assess (i) the distribution patterns of rhizomes and roots, (ii) the resprouting capacity of rhizomes and (iii) the overall resprouting potential of Reynoutria japonica and Reynoutria ×bohemica. For this purpose, we characterised the underground organs of six established and undisturbed populations and carried out resprouting tests with rhizomes in a greenhouse. Our results highlighted that the rhizome biomass of both taxa is mainly concentrated in the top 40 cm of soil, although some outlying rhizome organs may be found deeper down depending on soil compaction. On average, the observed density of nodes per square metre was 2646, ranging from 1825 in compact soil to 3825 in loose soil. Conversely, roots mostly occur in deeper soil layers. The rhizome resprouting capacity was significantly explained by pith brightness, organ diameter and taxon. Based on these findings, we estimated the overall potential of resprouting nodes by linking the number and characteristics of visible rhizomes along the soil profile to their resprouting capacity. We obtained expected densities of 1981 ± 198 and 1935 ± 305 nodes/m2 for R. japonica and for R. ×bohemica, respectively. We conclude with practical recommendations on incorporating preliminary rhizome depth and resprouting potential assessments into management practices to optimise resource allocation.

Titre : Long-term dynamics of tree of heaven (Ailanthus altissima) in central European forests Type de document : Imprimé Auteurs : Julia Isler ; Harald K. M. Bugmann ; Marco Conedera ; Timothy Thrippleton Année de publication : 2023 Article en page(s) : 1149-1166 Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Résumé : Since the 1950s, the tree of heaven (Ailanthus altissima) has progressively invaded forests in southern Switzerland and is becoming a growing concern also north of the Alps. Recent studies have increased the understanding of the species’ ecology, but its role in long-term stand dynamics remains uncertain. Therefore, we simulated the long-term dynamics of unmanaged and managed forest stands in southern and northern Switzerland under current and future climate conditions (RCP8.5) using the forest gap model ForClim. Our results indicate that A. altissima will increase its presence in the short term (< 100 yrs), but does not gain dominance in the long term (> 200 yrs), confirming its pioneer character. Timber harvesting led to an increasing share of A. altissima compared to unmanaged stands. Overall, our findings suggest that in the long run, a competitive displacement of native dominant species by A. altissima appears unlikely, with the exception of drought-prone sites under strong climate change. Furthermore, our findings underline the importance of the frequency and intensity of forest management for the long-term abundance of A. altissima in forest stands.

Titre : Low litter cover, high light availability and rock cover favour the establishment of Ailanthus altissima in forests in southern Switzerland Type de document : Imprimé Auteurs : Simon Knüsel ; Marco Conedera ; Harald K. M. Bugmann ; Jan Wunder Année de publication : 2019 Article en page(s) : 91-116 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Ailanthus altissima (Mill.) Swingle, 1916 Résumé : Future forest composition is uncertain in many areas due to climate change. The spread of non-native species adds to these uncertainties, particularly in forests recently colonised by novel tree species. To anticipate future forest composition, and thus the provision of ecosystem services, a thorough understanding of the factors influencing the establishment of non-native tree species is essential. We studied the presence and abundance of regeneration of Ailanthus altissima (Mill.) Swingle in 89 plots on a regular grid in three sites in southern Switzerland to determine the main drivers of its establishment. All sites are located in abandoned, i.e. currently unmanaged stands of Castanea sativa Mill. Propagule pressure is caused by single mature A. altissima that colonised the area ca 40 years ago. We found high rock cover, low litter cover and high light availability to be the most important predictors for the presence of A. altissima regeneration, whereas its abundance was positively influenced by high light availability, low litter cover and high browsing on regeneration of competing species. However, the presence models performed much better than the abundance models. Interestingly, the most important factors favouring the establishment of A. altissima in recently undisturbed sites were found to be similar in a nearby site after a severe forest fire, which suggests a similar establishment strategy after a disturbance as in recently undisturbed forests. Based on our results we expect a further expansion of the species in lowland forests currently dominated by C. sativa, likely controlled primarily by light availability.
