“…As in the restoration of sedge/grass wetland adjacent to West Creek, a tributary to nearby Braddock Bay (Wilcox and Healy, 2016), our results suggest that active seeding of mounds can facilitate development of the plant community. A similar conclusion was drawn for reed canarygrass control in tidal freshwater wetlands (Sinks et al, 2021). Diefenderfer et al (2018) concluded that plant associations on mounds were different from other areas of wetlands and that seeding plans should relate to elevation/soil moisture preferences of desired species.…”

“…In Typha-invaded wetlands, native seed banks become increasingly degraded with stand age (Lishawa et al, 2015). While seed addition in post-invasive restoration yields mixed success, it is often viewed as a worthwhile bet-hedging strategy (e.g., Pastorok et al, 1997;Bucharova and Krahulec, 2020;Kettenring and Tarsa, 2020;Sinks et al 2021).…”

“…We combined several Typha suppression methods in the restoration in Buck Pond and Buttonwood Creek wetlands --excision (cutting and mowing), herbicide treatment, soil moisture amelioration via elevation augmentation (spoil mound creation), and seed addition. Use of multiple methods is recommended and has become more common in invasive control efforts and more often successful than single methods alone (Galatowitsch et al, 1999;Bansal et al, 2019;Lishawa et al, 2019;Sinks et al, 2021).…”

Long-term data sets documenting temporal changes in vegetation communities are uncommon, yet imperative for understanding trends and triggering potential conservation management interventions. For example, decreasing species diversity and increasing non-native species abundance may be indicative of decreasing community stability. We explore long-term plant community change over a 40-year period through the contribution of data collected in 2019 to two historical datasets collected in 1979 and 1999 to evaluate decadal changes in plant community biodiversity in a tidal freshwater marsh in the Fraser River Estuary in British Columbia, Canada. We examine whether characteristic plant assemblages are consistent over time, whether alpha (α) and beta (β) diversity change within and between assemblages, and whether associated indicator species change. We found that plant assemblages were characterized by the same dominant indicator species, but most other indicator species changed, and that overall αdiversity decreased while β-diversity increased. Further, we found evidence for plant assemblage homogenization through the increased abundance of non-native invasive species such as yellow ag iris (Iris pseudacorus) and reed canary grass (Phalaris arundinacea). These observations may inform concepts of habitat stability in the absence of pulse disturbance pressures, and corroborate globally observed trends of native species loss and non-native species encroachment. Our results indicate that within the Fraser River Estuary, active threat management may be necessary in areas of conservation concern in order to prevent further native species biodiversity loss.

“…For example, projects such as habitat creation through dredged material placement and shoreline enhancement may benefit salmon and numerous other species, but they have their own risks. Moreover, lessons learned from pilot projects and experiments (Sinks et al 2021) serve as a springboard for other new ideas.…”

Ecological restoration programs in dynamic coastal environments can benefit from adaptive management, including an iterative process for identifying and addressing critical uncertainties. We highlight key developments under the three pillars that have increased the rate of restoration by the Columbia Estuary Ecosystem Restoration Program (CEERP) over 20 years: science, coordination, and management. We show how such programs can be institutionalized to ensure that estuary ecosystems are better understood, conserved, and restored. The principal conservation effort under CEERP is to reconnect historical floodplain wetlands to the mainstem. The program also supports other restoration actions that demonstrate a high potential to benefit ecosystem function and endangered salmon populations; however, there is greater uncertainty regarding these less-utilized techniques. Through adaptive management, we address technical uncertainty regarding benefits to the environmental resource and programmatic uncertainty pertaining to decision-making. Here, we examine three periods of CEERP growth to establish how complementary research and restoration actions have improved program outcomes over time. We highlight the tools and processes that were developed and integrated into the program to refine program strategy, improve project design, and maximize ecological benefits. CEERP supported 77 restoration projects and reconnected over 7,000 acres of floodplain habitat to the lower Columbia River between 2004 and 2021. Building on these successes, we outline current plans to better engage landowners and local communities, solicit new project types, and maintain enough flexibility within the program to adapt to new priorities.
