    Description

    The flora of the San Pedro Riparian National Conservation Area (SPRNCA) consists of 618 taxa from 92 families, including a new species of Eriogonum and four new State records. The vegetation communities include Chihuahuan Desertscrub, cottonwood-willow riparian corridors, mesquite terraces, sacaton grasslands, rocky outcrops, and cienegas. Species richness is enhanced by factors such as perennial surface water, unregulated flood regimes, influences from surrounding floristic provinces, and variety in habitat types. The SPRNCA represents a fragile and rare ecosystem that is threatened by increasing demands on the regional aquifer. Addressing he driving forces causing groundwater loss in the region presents significant challenges for land managers.
