ARE NON-PERENNIAL STREAMS CONSIDERED EQUALLY VALUABLE AND WORTHY OF CONSERVATION AS PERENNIAL STREAMS?
Current paradigms in river science and management have emerged largely from studies of perennial rivers. This lack of scientific attention to and conservation efforts for intermittent and ephemeral streams may have biased public perceptions about temporary rivers and their ecological importance. Understanding the social perception of non-perennial streams can help improve the management actions aimed at their conservation, and guide science communication to improve public awareness of these ecosystems. We carried out an image-based survey about the perception of non-perennial streams with undergraduate and graduate students of three US universities located in different climate contexts: University of California at Berkeley (Mediterranean climate), University of Arizona (desert climate), and University of Washington (Oceanic climate). The survey displayed nine stream images representing different hydrological statuses: flowing, isolated pools, and dry riverbeds. Observers were asked to evaluate each image for seven aspects: aesthetics, naturalness, habitat for biodiversity, habitat for fish, need of human intervention to improve the system, importance for human well-being, and worthy of conservation. Survey responses show that non-perennial streams are generally less valued than their perennial counterparts. However, climate context and other factors influence respondents’ valuation of these ecosystems.
