Budalen 2023 Plant Pollinator Survey

Study Extent

The study was carried out in the Budalen subalpine landscape conservation area (33 km^2), laying at 600-900 m.a.s.l. The sampling was carried out in 9 sites with the following coordinates: FH1: 62.734964N, 10.683115E FH2: 62.734905N, 10.686017E FH3: 62.736355N, 10.683845E EG1: 62.732242N, 10.700742E, EG2: 62.731253N, 10.705989E, EG3: 62.732208N, 10.702540E, IG1: 62.728650N, 10.702922E, IG2: 62.728993N, 10.702122E, IG3: 62.729156N, 10.701814E. Each site was 50m in length and 25m in width. Within each site, 5 transects were established, each 5m apart from the previous. In each site, a plant survey and a pollinator survey were carried out. For the plant survey, 5 quadrats were placed over the length of each transect. In each quadrat, the frequency of flowering plants was recorded. For the pollinator survey, observers walked up and down each transect and recorded every plant-pollinator interaction, as well as every flying pollinator observed along the transect and 2.5m to each side of the transect. The recording time for each transect was approximately 5 minutes. The sampling was carried out over the course of the summer 2023, from 19.06.2024 to 02.08.2023 in three separate sampling events: 19.06.2023 - 21.06.2023, 07.07.2023 - 10.07.2023, 01.08.2023 - 03.08.2023.

Method steps

1. For the plant survey, 5 quadrats were placed over the length of each transect. In each quadrat, the frequency of flowering plants was recorded. For the pollinator survey, observers walked up and down each transect and recorded every plant-pollinator interaction, as well as every flying pollinator observed along the transect and 2.5m to each side of the transect. See Sampling Description for more details. The raw data files were processed using R (v 4.3.2) and the scripts used to format the data into a DarwinCore-compliant format. The scripts used are available from a public Github repository.

For the vegetation data given here, the data represents the frequency of the plant species which were flowering at the time of survey. This data should not be used to infer on the absence of plant species, as a lack of recording of a species in this dataset simply means that this species was not flowering at the time of sampling. Similarly, for the insect records included here, they are only the species seen interacting with the plants at the time of the survey.
