Abstract
This study evaluated native and invasive plant responses to integrated pest management approaches. We used different combinations of grazing (G), herbicide (H), and mowing (M) to test the effectiveness in these approaches for the recovery of native species. This site is dominated by annual invasive grasses and a few invasive forbs. The aim of the study was to assess how management might aid in the recovery of native plants.
We collected plant percent cover and richness over the course of two years using a Braun-Blanquet cover class scale. Percent cover was converted into midpoint values for analysis. Mean midpoint values were used for final analyses to detect significant differences among treatments groups. We also used mean midpoint values to visualize the data using box plots, which indicated trends for both native and invasive plants in response to the treatments.
The data should be reproducible, and can be reused to determine how these management approaches impacted the plant community. Using the raw data from YEAR 1 and YEAR 2 can also be used to visualize plant community composition data using analyses like NMDS and ANOSIM/SIMPER.

Description of the data and file structure
Plant percent cover was collected using a modified Braun-Blanquet cover class scale. Percent cover was converted into mid point values for analysis. Data shows mean midpoint values and raw data in which mean values can be extrapolated.
Files and variables
File: Dryad_IPM.xlsx
Description:
Variables
-
each sheet contains either the raw data or the mean midpoint values ready for analysis
-
mean midpoint values are derived from the raw data
-
the first sheet (YEAR 1) in the document contains plant percent cover data from before and after treatment implementation
-
all analyses were conducted using the "after" data to test for treatment effects
-
the "before" data can be used to look at percent changes from before and after the treatments
-
For the YEAR 2 sheet, raw data is provided from plant cover collected in the second year of the experiment.
-
there are a total of 5 treatments and 10 replicates for a total of 50 values per observation
- the plot numbers (1-50) and indicated as PLOT columns
-
treatments are as follows: C=control, G=grazing, GM=grazing+mowing, GH=grazing+herbicide, and GHM= grazing+herbicide+mowing
-
species codes are displayed as 4 letter abbreviations denoting genus and species (2 first letters of each)
- species codes and corresponding names can be found in the sheet titled Species codes.
- SPP_CODE=species code, SPP_NAME= species name, and SPP_STATUS= species status (designated as either native or invasive)
- the status (i.e., native or invasive) is also indicated per species.
- species codes and corresponding names can be found in the sheet titled Species codes.
-
In the Yr1 and Yr2 AVG sheets, NAT = Native, INV= invasive, COV=cover, and RICH=richness
- the cover and richness values for each native and invasive plants correspond to each of the implemented treatments.
Code/software
All statistical tests were conducted using the vegan and dplyr packages in R Studio statistical software v4.1.2
Other packages were also for aesthetic purposes (e.g., ggplot2, cowplot, tidyverse...etc).
