The decision upon which defoliation frequency to apply depends on the farming intensity. Assuming a reduced total herbage accumulation near trees in silvopastoral systems, frequent defoliations with high HEFF become less worthwhile—at least in specific spatial configurations. This makes an extensive management near trees an interesting option because it promotes other grassland‐related ecosystem services such as biodiversity. The present study first analysed the interaction between defoliation frequency and position to trees on the total, dead and live herbage accumulation and the HEFF at two silvopastoral sites with short‐rotation coppices in Germany. In addition, the total grassland–tree interface in Germany was assessed from land use and land cover maps of Germany based on satellite data to approximate the potential of grassland extensification near trees. The total herbage accumulation near trees declined by up to 41% but the HEFF was not affected by the position. Consequently, any intensification is not paid‐off by adequate productivity and herbage quality in terms of HEFF and tree‐related losses in herbage accumulation are expected up to a distance of 4.5–6 m. Applying a 4.5 m border on satellite data, we found that up to 4.4% (approximately 2200 km2) of the total grassland area in Germany is at a tree interface and potentially suitable for extensification. These findings indicate substantial potential for biodiversity conservation in grasslands with low trade‐off for high‐quality yield."],["dc.description.abstract","Herbage production in silvopastoral grassland is limited because of shade close to the tree lines. That makes an intensive defoliation frequency not worthwhile because it is not paid off by high yields. This makes other grassland‐related ecosystem services near trees attractive. We estimate that 4.4% of the German grassland is close to tree lines offering potential for extensification. image"],["dc.description.sponsorship","Bundesministerium für Bildung und Forschung http://dx.doi.org/10.13039/501100002347"],["dc.identifier.doi","10.1111/aab.12681"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/82581"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-399"],["dc.publisher","Blackwell Publishing Ltd"],["dc.relation.eissn","1744-7348"],["dc.relation.issn","0003-4746"],["dc.relation.orgunit","Zentrum für Biodiversität und Nachhaltige Landnutzung"],["dc.rights","This is an open access article under the terms of the Creative Commons Attribution‐NonCommercial‐NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non‐commercial and no modifications or adaptations are made."],["dc.title","Impacts of cutting frequency and position to tree line on herbage accumulation in silvopastoral grassland reveal potential for grassland conservation based on land use and cover information"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

Trees introduce diversity into grasslands, as they establish microsites with different conditions through modification of light availability and soil chemical parameters. In orchards, livestock may promote distinct nutrient deposition as they tend to rest and defecate under trees, which might affect plant species composition and richness. In 42 orchards within the Rhenish Uplands (Germany) we studied how different grazer species (cattle, horses and sheep) affect soil nutrient accumulation (P2O5 and K2O) in microsites along a tree-proximity-gradient (under the crown, ecotone, non-tree affected area) and how this influences plant species richness in microsite habitats and at paddock scale. Our results show higher amounts of K2O and P2O5 and fewer numbers of species under the crown compared to the ecotone and non-tree affected area. Further, we found differences in plant species richness at the paddock scale among different grazer species with higher diversity on horse compared to cattle and sheep grazed pastures. Increasing grazing intensity promoted K2O deposition and decreased species richness at microsite and paddock scale."],["dc.identifier.gro","3148103"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/5451"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.publisher","EGF"],["dc.publisher.place","Norway"],["dc.relation.conference","26th General Meeting of the European Grassland Federation"],["dc.relation.eventend","2016-09-08"],["dc.relation.eventlocation","Trondheim, Norway"],["dc.relation.eventstart","2016-09-04"],["dc.relation.isbn","978-82-17-01677-9"],["dc.relation.ispartof","The multiple roles of grassland in the European bioeconomy"],["dc.title","Tree-livestock interaction promotes nutrient shift and influences plant species richness in orchards"],["dc.type","conference_paper"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]
