Abstract

These data were collected in support of a Minnesota Department of Transportation funded study evaluating roadside plantings. The goal of our study was understand how roadside pollinator forage is affected by planting pollinator-friendly seed mixes in roadsides in Minnesota, USA. We used a field study of mixed-age roadside plantings to assess this flower diversity in roadsides planted with status quo non-native seed mixes to those planted with pollinator friendly, native seed mixes. We found that while these native seed mixes did increase the abundance of native flowers, the roadsides' flower communities of native and non-native seedmixes converged through time to grass dominated and unplanted colonizing species. This repository contains the complete datasets as a comma-separated-value files and Program R code necessary to replicate the data prep, exploration, analysis, and visualizations presented in the manuscript.

Description

The data files contain plant observations for 63 roadside sites observed during the time period of May-Aug of 2021. The Program R code here will read in and summarize those data, complete analyses needed to duplicate the results of the manuscript, and create visualizations used in publication. See readme file for more information.
