In this study we ask: How have the abundance, composition and
distribution of riparian vegetation along ephemeral streams
changed over the course of 35 years in response to construction of
the CAP canal? We document spatial shifts in plant distribution
along longitudinal and lateral river dimensions, thereby providing a
much needed understanding of plant community changes in
response to anthropogenically altered ephemeral channels. Understanding
the effects of the canal on riparian vegetation is critical
for implementing sustainable practices in desert environments.
