Both are plant consumers that can strongly control the recruitment of woody seedlings or saplings to taller height classes. Without such ‘consumer control’, many grass-dominated ecosystems would convert into woodlands or forests. While extensively studied in savannas, few have explored the effects of these disturbance regimes on woody recruitment under temperate conditions. We exposed saplings of the five most common European tree species to fire and herbivory in a full factorial experiment in a savanna-like wood-pasture on the Swedish west coast. After three years, we evaluated the effects of fire and herbivory on tree sapling survival and height increment. The tree species used, varying in traits and in expected response to fire and herbivory, were Scots pine Pinus sylvestris, Norway spruce Picea abies, European oak Quercus robur, Silver birch Betula pendula and Small-leaved lime Tilia cordata. Fire and herbivory, and their combination, had a negative effect on both survival and height increment but with large differences among species. Sapling survival was reduced to a similar extent for all species except Q. robur, which was not affected by fire. Both processes, and the combination, reduced height increment of B. pendula, while only herbivory reduced the height increment of Q. robur. P. sylvestris, P. abies and T. cordata had a similar height increment in all treatments. Overall, the combined effect of fire and herbivory was similar to the effect of herbivory alone, indicating no additional effect of fire when herbivores were present. Our experiment shows how fire and herbivory can cause a strong consumer control on the recruitment of European temperate trees on a wood-pasture, by reducing the recruitment of saplings to the next demographic stage. Responses to fire and herbivory differed from general predictions of species performance which highlights the need for further experiments addressing drivers of landscape openness and tree-grass interaction. The data set consists of one file with data on tree saplings suvival and height increment, and one file with explanations to the variables.

The aim of the project was to quantify whether linear infrastructure habitats (road verges and power-line corridors) support biodiversity by assessing the influence of the area of these habitats in the landscape, their contribution to landscape connectivity and population persistence. The linked data was collected by surveying butterflies, bumblebees, and vascular plants in five types of prevalent grasslands (pastures, road verges along small gravel roads, road verges along big paved roads, power line corridors, and field borders). These grasslands were embedded in 32 landscapes with area 4 km² each, that differed in the area of linear infrastructure habitats (road verges and power line corridors) and semi-natural grasslands of high nature value, while other land-use types were kept constant. The landscapes were dominated by forest. Within each grassland habitat, the surveyor established a 200 m transect and then identified all butterflies and bumblebees along it. For plants, a 1 x 1 m quadrat was established at the centre of a 50 m section in each transect, i.e. each transect had four plots in which all plant species were identified. Denna studie är en del av projektet GINFRA – green rights-of-way infrastructure for biodiversity and ecosystem services. Projektets huvudsyfte var att kvantifiera om linjära infrastrukturmiljöer (vägkanter och kraftledningsgator) bidrar till mångfalden av växter och insekter i olika rumsliga skalor. Detta gjordes genom att uppskatta hur linjära infrastrukturmiljöers mängd i landskapet bidrar till mångfalden samt hur mycket de bidrar till landskapets konnektivitet. Datan samlades genom att inventera dagfjärilar, humlor, och växter i fem typer av gräsmarker (betesmarker, vägrenar längs enskilda vägar, vägrenar längs allmänna vägar, kraftledningsgator, och åkerkanter). Alla dessa habitat typer fanns inom 32 landskap med area 4 km2 som skilde sig i areal av linjära infrastrukturmiljöer (vägrenar och kraftledningsgator) och ängs-och betesmarker. Arealen av andra markanvändningar var konstanta mellan landskap och alla landskap var skogsdominerade.
