Resource quantity and heterogeneity drive successional plant diversity in managed and unmanaged boreal forests

Here, we describe the data and methods supporting a study on how disturbances such as forest fires and clear-cutting influence understory vegetation diversity in boreal Scots pine (Pinus sylvestris) forests in Northern Sweden. The research contrasts two chronosequences, one under rotational management (clear-cutting, soil scarification, and thinning) and one unmanaged and fire-origin, to examine how resource availability and heterogeneity relate to alpha and beta diversity over a temporal gradient.
The understory vegetation of boreal forests plays a crucial role in maintaining biodiversity by creating habitats, supplying food resources, and regulating microclimate and soil conditions. This essential layer is frequently affected by disturbances such as forest fires and clear-cutting, which significantly alter understory communities and the ecosystem resource availability and heterogeneity. This study aimed to understand how these disturbances influence the spatial and temporal dynamics o..., , , # Data from: Resource quantity and heterogeneity drive successional plant diversity in managed and unmanaged boreal forests
