Ecological theory provides strong support for habitat restoration / Péter Török in Biological conservation, vol. 206 (Février 2017)

Public [article]  inBiological conservation > vol. 206 (Février 2017) . - pp. 85-91 Titre : Ecological theory provides strong support for habitat restoration Type de document : texte imprimé Auteurs : Péter Török, Auteur Année de publication : 2017 Article en page(s) : pp. 85-91 Langues : Anglais (eng) Catégories : [habitats/milieux] 3 - Landes, fruticées et prairies Mots-clés : dispersion  restauration  restauration des prairies  hétérogénéité du paysage  écologie théorique  stratégie de restauration Résumé : "The involvement of ecological theory in habitat restoration has significantly increased in the past decade. However, despite the fact that the field of restoration ecology has grown academically strong in recent years, there are still visible gaps between the advancing discipline of theoretical ecology and current approaches of habitat restoration. We propose bridging these gaps by linking recent developments in theoretical plant ecology with the main questions every restoration practitioner should ask, namely: Q1) How to identify target species and baseline conditions for restoration of the selected habitat?; Q2) When can one count on spontaneous dispersal and when are additional efforts required for facilitating dispersal of desired species?; Q3) Which factors determine the successful establishment of target species and assembly of target communities?; and Q4) What time-scale needs to be considered for the evaluation of species colonisation and restoration success? Knowledge and experience accumulated in practical restoration can considerably benefit theoretical ecology for example by improving the understanding on (i) temporal changes in community, (ii) species assembly, (iii) species dispersal and establishment and (iv) landscape-scale dynamics of biodiversity. We emphasise that to improve joint thinking of practical restoration and theoretical ecology, restoration-problem-driven theoretical research is necessary. We suggest either (i) to translate and link the current findings of theoretical ecology to restoration strategies; and/or (ii) to summarise practical restoration needs by formulation of questions and testable hypotheses based on theory."

Factors threatening grassland specialist plants - A multi-proxy study on the vegetation of isolated grasslands / Balázs Deák in Biological conservation, vol. 204, n°B (Décembre 2016)

Public [article]  inBiological conservation > vol. 204, n°B (Décembre 2016) . - pp. 255-262 Titre : Factors threatening grassland specialist plants - A multi-proxy study on the vegetation of isolated grasslands Type de document : texte imprimé Auteurs : Balázs Deák, Auteur ; Orsolya Valkó, Auteur ; Péter Török, Auteur ; Béla Tóthmérész, Auteur Année de publication : 2016 Article en page(s) : pp. 255-262 Langues : Anglais (eng) Catégories : [ZG] Hongrie [habitats/milieux] 3 - Landes, fruticées et prairies [habitats/milieux] 8 - Terres agricoles et paysages artificiels Mots-clés : schéma agro-environnemental  fragmentation de l'habitat  Kurgan  steppe Résumé : "Land use changes have resulted in the loss and isolation of semi-natural habitats worldwide. In intensively used agricultural landscapes the remnants of natural flora only persist in small habitat islands embedded in a hostile matrix. In the steppe zone burial mounds, so-called kurgans, have the potential to preserve the natural flora and act as local biodiversity hotspots. Exploration of the factors driving biodiversity in isolated habitat fragments is crucial for understanding the ecological processes shaping their vegetation and for designing effective strategies for their protection. We sampled the vegetation of 44 isolated kurgans in East-Hungary and studied the effects of habitat area, slope, recent disturbance, past destruction and the level of woody encroachment on the species richness and cover of grassland specialist and problem species (competitor weedy species). We used model selection techniques and linear models for testing relevant factors affecting specialist species in grassland fragments. We found that the biodiversity conservation potential of kurgans is supported by their steep slopes, which provide adequate habitat conditions and micro-climate for steppic specialist plant species. Specialist species are threatened both by recent disturbances and encroachment of alien woody species, especially black locust. Factors supporting specialist species suppressed problem species by providing unfavourable environmental conditions and putting them at a competitive disadvantage. We identified that woody encroachment and current disturbances affect the vast majority of kurgans, posing a serious threat to grassland specialist species. Thus, there is an urgent need to integrate active conservation measures into the current passive protection of kurgans."

Urgent need for updating the slogan of global climate actions from “tree planting” to “restore native vegetation” / Csaba Tölgyesi in Restoration Ecology, vol. 30, n°3 (Année 2022)

Public [article]  inRestoration Ecology > vol. 30, n°3 (Année 2022) . - e13594 Titre : Urgent need for updating the slogan of global climate actions from “tree planting” to “restore native vegetation” Type de document : texte imprimé Auteurs : Csaba Tölgyesi, Auteur ; Elise Buisson, Auteur ; Aveliina Helm, Auteur ; Vicky M. Temperton, Auteur ; Péter Török, Auteur Année de publication : 2022 Article en page(s) : e13594 Langues : Anglais (eng) Catégories : [habitats/milieux] 4 - Forêts Mots-clés : boisement  perte de biodiversité  défi de Bonn  changement climatique  stratégie européenne  restauration  plantation d'arbres Résumé : "The prevailing nature-based solution to tackle climate change is tree planting. However, there is growing evidence that it has serious contraindications in many regions. The main shortcoming of global tree planting is its awareness disparity to alternative ecosystem types, mainly grasslands. Grasslands, where they constitute the natural vegetation, may support higher biodiversity and a safer, soil-locked carbon stock than plantations and other forests. We suggest replacing “tree planting” by “restore native vegetation.” This improved action terminology reduces the risks of inappropriate afforestation and, by diversifying target ecosystem types, does not reduce but increases potential land area for nature-based climate mitigation."
