Non-native plants have invaded much of the western United States over the past 100 years. Most of these invasive species are early-successional, yet they appear to persist for decades. The goal of this research was to describe non-native and native plant abundance in ex-arable and adjacent undisturbed fields over time.

Plant species abundances were measured in 25 fields that represent a 52-year chronosequence of agricultural abandonment. These fields were monitored for 13 years from 2002 to 2015. In each field species abundances was measured using visual observations in 15, 1m2 quadrats located 5 meters or 50 meters from historic tillage boundaries. Five and 50 meter transects were located both within and outside of historically tilled fields.

Each row of data includes the percent ground cover of each species in a quadrat as determined by visual observation.
Data from the first three years in this dataset were described by Kulmatiski in:

Research was conducted over a roughly 25 km stretch of the Methow Valley centered around Twisp to Winthrop, WA, USA.
Data is contained in one file named Winthropvegetation.csv. Species codes are described in speciescodes.csv.
