Data and R code used to study the effects of cattle and cervids on plants and pollinators on young spruce plantations in boreal forest

The data was collected in Norway in 2021 and 2022 to study the effects of cattle and cervids on plants and flower-visiting insects in young spruce plantations. We compared data from inside to outside the grazing area.
The plot key file containes data on our sampling plots, such as plotID, coordinates, study area, graing area (inside/outside), fenced (yes/no) and forest productivity ("bonitet").
The sward data files contain sward height of graminoids, herbs and woody plants in the field layer vegetation.
The plant data files contain plant abundance on species level of graminoids, herbs and woody plants in the field layer vegetation.
The flower data files contain flower abundance on species level of herbs and woody plants in the field layer vegetation.
The flower visitors data file contains abundance of bumblebees, hoverflies, other flies, butterflies, honeybees, solitary bees and other insects.
The bumblebee and hoverfly data files contain species identifications of all caught bumblebees and hoverflies.
In the sward height script we modelled sward height in relation to fencing (fenced/unfenced) and grazing area (inside/ outside).
In the plant abundance script we modelled the abundance of graminoids, herbs and woody plants in the field layer vegetation in relation to fencing (fenced/unfenced) and grazing area (inside/ outside).
In the plant species richness script we modelled the species richness of graminoids, herbs and woody plants in the field layer vegetation in relation to fencing (fenced/unfenced) and grazing area (inside/ outside).
In the flower abundance script we modelled the abundance of flowers on herbs and woody plants in the field layer vegetation in relation to fencing (fenced/unfenced) and grazing area (inside/ outside).
In the flower species richness script we modelled the species richness of flower carrying herbs and woody plants in the field layer vegetation in relation to fencing (fenced/unfenced) and grazing area (inside/ outside).
In the insect abundance script we modelled the abundance of flower visiting insects in relation to fencing (fenced/unfenced) and grazing area (inside/ outside).
In the insect species richness script we modelled the species richness of bumblebees and hoverflies in relation to fencing (fenced/unfenced) and grazing area (inside/ outside).

本数据集于2021至2022年在挪威采集，旨在探究牛类与鹿类对年轻云杉人工林内植物及访花昆虫的影响。本研究对比了放牧区域内外的采样数据。
样地关键文件包含采样样地的相关信息，包括样地ID、坐标、研究区域、放牧区域（区内/区外）、是否围栏（是/否）以及森林生产力等级（立地质量，bonitet）。
草层数据文件包含林下层植被中禾本科植物、草本植物及木本植物的草层高度数据。
植物数据文件包含林下层植被中禾本科、草本及木本植物的物种水平丰度数据。
花部数据文件包含林下层植被中草本与木本植物的物种水平花部丰度数据。
访花昆虫数据文件包含熊蜂（Bumblebees）、食蚜蝇（Hoverflies）、其他蝇类、蝴蝶（Butterflies）、蜜蜂（Honeybees）、独居蜂（Solitary bees）及其他昆虫的丰度数据。
熊蜂与食蚜蝇数据文件包含所有捕获的熊蜂及食蚜蝇的物种鉴定信息。
在草层高度分析脚本中，我们针对围栏状态（围栏/未围栏）与放牧区域（区内/区外）对草层高度开展了建模分析。
在植物丰度分析脚本中，我们针对围栏状态与放牧区域对林下层植被中禾本科、草本及木本植物的丰度开展了建模分析。
在植物物种丰富度分析脚本中，我们针对围栏状态与放牧区域对林下层植被中禾本科、草本及木本植物的物种丰富度开展了建模分析。
在花部丰度分析脚本中，我们针对围栏状态与放牧区域对林下层植被中草本与木本植物的花部丰度开展了建模分析。
在开花植物物种丰富度分析脚本中，我们针对围栏状态与放牧区域对林下层植被中具花草本与木本植物的物种丰富度开展了建模分析。
在昆虫丰度分析脚本中，我们针对围栏状态与放牧区域对访花昆虫的丰度开展了建模分析。
在昆虫物种丰富度分析脚本中，我们针对围栏状态与放牧区域对熊蜂与食蚜蝇的物种丰富度开展了建模分析。
