Abstract Pacifastacus leniusculus (Dana 1852), the signal crayfish, is a freshwater astacid native to Pacific Northwest and introduced in western Europe Japan. Though P. populations have been well-studied abroad, where they degrade local habitat biodiversity, their ecology natural history are less understood within range, fill key roles risk out-competition by exotic crayfish. The present study describes density, morphology, behavior of resident crayfish fourthorder Oregon stream, Tryon Creek, via surveys nine sites from June–September 2022. Across sites, there was an estimated average population density 0.08 m-2, no were detected. Amongst collected (n = 162), total body length (TL) ranged 13–90 mm, μ 53 mm. Branchiobdellidans colonized one four throughout damage appendages occurred at rate 0.45, likelihood both increased with TL. In case Tryon’s Hwy- 43 Culvert, showed potential signs stress; across numerous young juveniles resided gregariously. Despite study’s novel strides toward native-range characterization, further research encouraged establish well-rounded regional baseline.

The practice of stormwater management has evolved from a singular focus on drainage to multifaceted approach support integrated urban development. By contributing healthy, livable, ecological, and water sensitive cities, it is key tool promote Sustainable Development Goal 11 neighborhood metropolitan scales. A review the knowledge base for shows several attributes that favor an integrative achieve co-benefits across sectors. Functional areas its contributions include drainage, flood control, plain management, quality ecology, recreation, city beautification. Legacy path dependance affects potential reform land use practices, while being affected by climate change, sea level rise, urbanization, inequality, poor governance.
