Summary of mean frequencies of plant species from each comparison flora assigned to a coefficient of conservatism ranking (values 0 to 10), and frequency of plant species of each flora for wetland indicator status.

For coefficients of conservatism a zero (0) value represents an invasive species, a one (1) represents nonnative species, a two (2) is a non-conservative native species that is not specific to a habitat type [often considered weedy], and increasing numbers (to 10) represent species with a narrowing range of ecological tolerances and a decreasing ability to tolerate disturbance. These values follow Zomlefer et al. (2013) [36]. An NA value for wetland indicator status means that no wetland status was applied the species; wetland indicator statuses are facultative (FAC), facultative upland (FACU), facultative wetland (FACW), obligate wetland (OBL), and upland (UPL) [36].

保守性系数（coefficients of conservatism）的取值规则如下：取值0代表入侵物种（invasive species），取值1代表外来非本土物种（nonnative species），取值2代表不局限于特定生境类型（habitat type）的非保守性本土物种（non-conservative native species）[通常被视为杂草性的物种]；取值递增至10的物种，其生态耐性（ecological tolerances）范围逐渐收窄，耐受干扰（disturbance）的能力也逐步降低。该取值标准遵循佐姆莱弗等（Zomlefer et al., 2013）[36]的研究。湿地指示状态（wetland indicator status）为NA时，表示该物种未被赋予任何湿地指示类别；常见的湿地指示类别包括兼性（facultative, FAC）、兼性高地（facultative upland, FACU）、兼性湿地（facultative wetland, FACW）、专性湿地（obligate wetland, OBL）以及高地（upland, UPL）[36]。
