The broader significance is that riparian restoration reintroduces native species (pictured) and improves salmon spawning, rearing and migrating. Finally, riparian vegetation can help in understanding how to use the riparian restoration to strengthen salmon. (6/6) #POEcap

Results indicated that riparian restoration positively affects salmon habitat by increasing canopy cover, woody debris, litter mass and by providing pollutant protection to the river through natural filtering. Pictured is Bear Creek in 2018 (left) and 2023 (right). (5/6) #POEcap

At Whale Scout I used riparian restoration analysis to assist the organization in repairing salmon habitat. This was done by performing vegetation monitoring of plant species along Bear Creek (pictured) to examine the effects of riparian restoration. (4/6) #POEcap

Riparian restoration consists of removing invasive species such as the Himalayan blackberry bush and planting non-invasive, native species like the Douglas Fir. The image below depicts the aftermath of invasive removal on the left and native planting on the right. (3/6) #POEcap

The aim of this capstone project was to use riparian restoration to analyze how it affects salmon habitat on the riparian zone rivers and streams in Washington. As seen in the image below, the riparian zone is the area of land directly adjacent to the river. (2/6) #POEcap

Humans are reducing salmon habitat in rivers, making it easier for invasive species to take over rivers and streams in Washington. For instance, the Sammamish river (pictured) is densely populated with blackberries along the river’s edge. (1/6) #POEcap

Another key takeaway from my internship is that invasive species such as the Himalayan blackberry have the tendency to overpopulate salmon habitat, limiting the ability of native trees/shrubs to provide shade, litter mass, bank support and good water quality #ENVIR491 #POEcap

A key takeway from my internship is that there are particular species plants that benefit salmon. For instance, red alders help to increase nutrient levels in soil such as nitrogen and phosphorus in addition to providing woody debris #ENVIR491 #POEcap

I am also extremely grateful for @SnoKingWC who allowed me to borrow their water quality kit and tools that enabled me to monitor local tributaries in King County for my capstone project. πŸ™ #ENVIR491 #POEcap

Thank you @whalescout for allowing me the opportunity to contribute to their land conservation, education, outreach and research efforts that all seek to revitalize salmon and orcas in the PNW. πŸ™ #ENVIR491 #POEcap

Lauren S. Urgenson, an author in my bibliography, gave intriguing insights regarding the impacts of the invasive knotweed plant on riparian vegetation along Grandy Creek on Mount Baker. One result was that knotweed presence reduced native litter mass by 70%. #ENVIR491 #POEcap

Kirsten L. Sellheim, an author in my bibliography, provided valuable research regarding the links between gravel in rivers and salmon reproduction. The paper found that salmon need a blend of both coarse and fine sediments for their developing eggs. #ENVIR491 #POEcap

Would also be interested in learning more about salmon recovery on the Snake River? @waDNR #ENVIR491 #POEcap

I’d be interested to know what other salmon habitat restoration projects (such as the one on the Former Wayne Golf Course) are happening in Bothell? @CityofBothell #ENVIR491 #POEcap

Another valuable source for my research has been this paper which focused on understanding the ecological links between salmon nutrients and riparian biota health. Link: biomedcentral.com/1472-6785/… #ENVIR491 #POEcap

At Bear Creek, we laid a mulch pathway and did maintenance on the conifers (douglas firs, western red cedars and sitka spruces) by removing weeds, giving them more space to grow. We also spotted many native Douglas Spirea, an important riparian plant. #ENVIR491 #POEcap

At the @YMCASeattle meal site today in Redmond me and the other @whalescout interns utilized @SeattleAquarium interactive materials, a DIY felt board and coloring sheets to engage students! #ENVIR491 #POEcap
