Figure 5. — The Jornada Quadrat study is an ongoing longitudinal study of vegetation pattern and trends from 1915 to present. Data quality has varied throughout the data set (a) as different data collectors and data managers participated in the study (b). This has resulted in anomalies in the data set, including an unlikely decline and increase in Prosopis glandulosa (c). Refer to figure 2 for a description of the lifecycle represented in panel (a).
