ABSTRACTS

Restoration Actions from a Watershed Perspective: The City of Portland’s Framework for Integrated Management of Watershed Health (Chris Prescott)

The City of Portland has one of the most complete frameworks for integrated management of watershed health in the country. The goal of this framework is to recover watershed ‘health’ by hierarchical actions at catchment and site levels. As a part of this integrated management plan, a strong monitoring system has been applied that is used to inform and prioritize restoration actions and measure
its success. This presentation describes how river science has been integrated into Portland’s watershed planning efforts, and how monitoring plays a key role in guiding and adaptively managing the watershed management plan.

 

Tracking Tides and Time: Quantifying Wetland Restoration Outcomes and Landuse Change in the Urban Wildland Matrix of Muzzi Marsh (Dylan Chapple, WeiChen Hsu)

Long-term monitoring of restoration projects is rarely implemented, but provides essential insights into how ecosystems recover from disturbance.  Here, we examine a 15 year, field-collected data set and remotely sensed data from Muzzi Marsh, a nearly 40 year old tidal
wetland restoration site, and China Camp, a historic tidal wetland used as a reference site, to uncover ecosystem dynamics over time.  We find that directional change over the study period determines species composition at Muzzi Marsh, indicating that the site is still developing 30 years after initial restoration actions.  Further, we find that rainfall causes species composition to fluctuate at China Camp. 
Our findings highlight the need for long term monitoring at both restoration sites and reference sites to capture variation over time and shifting environmental conditions to aid in the planning of future restoration efforts in the San Francisco Bay.    

 

Piloting a Monitoring Protocol for California Conservation Corps LWD Projects (Shanna Atherton and Bingyao Zhu)

This paper addresses the issue of monitoring Large Woody Debris (LWD) projects performed frequently by one of the state’s most
prolific restoration groups--the California Conservation Corps (CCC). Through its Salmon Restoration Program, the CCC has enhanced over 1,800 miles of stream in an effort to restore vital coho, chinook and steelhead habitat on California's North Coast; however, limited time, funding, and incentives have restricted monitoring of these projects to pre- and post-project photo-monitoring, and an account of the number and location of LWD structures placed at each project site. Monitoring future CCC LWD projects is essential to identifying and enhancing their effectiveness in restoring salmonid habitat. Opportunities at the CCC, including access to Watershed
Steward Project members at at least two sites, trainings offered by project partners, and available survey equipment, as well as the desire to increase future project effectiveness make the establishment of a simple monitoring protocol feasible for this organization. Keeping both opportunities and constraints in mind, we have developed a monitoring protocol that allows the CCC to monitor changes in physical habitat characteristics often associated with salmonids--pool depth and frequency--to assess the effectiveness of installed
LWD structures. The protocol consists of collecting long profile,
cross-section, and LWD data  in a sample reach for each project in three phases: pre-project, as-built, and post-project--with post-project data collected only after large storm events. We piloted this protocol on South Fork Cottaneva Creek, which already had benchmarks and a pre-project data set (obtained from the landowner, MRC) established, and revised the protocol based on our experience.  

 

Realizing the Potential of the Nile in Cairo (Amir Gohar)

The Nile, in general, and particularly in Cairo, is an ecological, cultural and social corridor that is not yet fully utilized. The 2011 Cairo workshop “Connecting Cairo to the Nile” identified the potential to increase accessibility to the river, suggested longitude trail system, proposed connecting the waterfront with adjacent neighborhoods and proposed expanding the ferry system. I studied a 2-km reach of the east bank in Maadi, a wealthy suburb about 10 km upstream of
the city centre, with relatively greener banks, availability of resources at the district level, higher awareness of local residents, physical setting allow for banks re-use, existence of community organizations (i.e. Tree Lovers and Midan).  Findings of fieldwork and interviews
show that: (i) species of native vegetation found are Phoenix Dactylifera, Jacaranda, Cortedarea and Papyrus alba; these are concentrated in 115 meter in southern part of the study area. (ii) Public access was categorized into: public space (accessible), private or semi public space (accessible with conditions), and prohibited (inaccessible). Along this representative stretch of the Nile, the public access was limited to 16%, the private or semi public makes 29% and the prohibited zones are 55%. (iii) Boating operations found to
be in three categories, floating hotels (Nile cruises), motor boats (including ferries) and sailing boats, all are scattered along the banks without an over all plan or organization, which affects water flow and block public access to the banks. To better develop the banks, I recommend (i) maintaining existing riparian vegetation and expand it to other areas with healthy banks or planted nurseries, (ii) connecting open public spaces to create a pleasant walking trail along the banks in addition to improving public access by relocating government buildings (such as the police or military facilities) and facilitate
access to the river for general public, (iii) reducing the anchoring points to two locations and redistribute boating operations to group all motor boats to use the ferry anchoring points and all the sailing boats to use Al-Yacht club marina.

 

A Tale of Two Small Urban East-Bay Streams: Contrasting Cerrito and Winter Creek Restorations
(Miriam Eason, Daisy Gonzalez)

Winter Creek and Cerrito Creek are intermittent East Bay streams that share geomorphological and institutional factors. Both streams are valuable educational and aesthetic assets within University of California, Berkeley owned gardens as some of the only open channel streams in primarily culverted channel watershed. However, they are both in steep upper watershed locations and have suffered erosion and incision due to upstream development (PWA, 2005; Jewell & Norcross, 2007). Our cross section profiles compared with 2010
cross sections indicated that Winter Creek remained stable and the 2009 PWA-ESA restoration project goals of bank stabilization and flood control were achieved. The Winter Creek design used rock revetment bank armoring, extensive re-grading of the channel and banks, a gabion supporting the outfall culvert, rock check dams, erosion fabric and native plantings to support the bank (Hanford Arc website, 2009). We compared geological, watershed context,
ownership, and permit requirements of Winter Creek with Cerrito Creek and determined that the two creeks were similar enough that Winter Creek could be a precedent for a similar bank stabilization and flood control intervention at Cerrito Creek. Through interviews and field surveys we determined that Cerrito Creek is in need of a serious intervention, however funding is not available for a project of Winter Creek magnitude (Tim Pine, UCB Office of Health and Safety, personal communication 2013). Instead bank stabilization and flood
control efforts at Cerrito Creek included some geotextile bank stabilization, re-grading in some channel and bank locations and removal of invasive plants without replacement natives. We recommend a Cerrito Creek feasibility study to determine opportunities and constraints, costs and potential funding sources to
move towards bank stability and flood management and enable this creek to remain a valuable asset.

 

Assessing Success of a Compound Channel: Tassajara Creek, Dublin, 14 years on (Natalie Stauffer, Ashton Wesner, and Joseph Burg)

Tassajara Creek in Dublin, California was an early compound channel stream restoration project aimed at stabilizing channel incision, restoring riparian vegetation, and establishing an open flood plain. It is seen as a model for other urban stream restorations. Six post-project studies have been done along the one-mile restored reach in order to determine the success of the project, particularly in stopping rampant incision (Lave 2002, Lave 2003, Krofta and Novotney 2003,
Oden and Dehollan 2004, Tompkins 2006, Chan and Heard, 2006). Our team set out to resurvey eight cross sections, established by Hudzik and Truitt, to see if any significant change could be detected in the channel morphology at six cross-sections since the last survey in 2006 (Chan and Heard). We encountered numerous difficulties in accurately repeating past measurements including distant benchmarks, dense vegetation, missing cross section endpoints, and
inconsistent documentation of survey methods and results in past reports. Although our survey results indicate that ongoing incision is probable, and we conclude that continued monitoring on the Tassajara restoration reach is necessary, we focus on the practicalities of monitoring practices and documentation. We present a framework for evaluating practical obstacles to implementing survey monitoring, and conclude with improved requirements for monitoring plans that
will address obstacles such as dense vegetation, impermanent markers, and inconsistent measuring methods. 

 

Evolution of Creek Geomorphology under the Influence of Logjams: Redwood Creek, Marin
County, California (Aysha Massell, Grant Saita, Patrick Webb)

Redwood Creek flows from Mount Tamalpais to Muir Beach in Marin County California. Historical human disturbance of the creek channel has resulted in an unnatural and degrading channel system, with a largely reduced salmonid habitat. A fall 2003 restoration project sought to restore fish habitat and stabilize eroding banks within the Banducci site reach. Restoration included a re-vegetation plan
for stream banks, removal of an existing artificial levee, and insertion of multiple large woody debris (LWD) structures. Our study follows previous post-project analyses (2004, 2010), and tracks the geomorphological changes set in motion through the restoration project, in an attempt to both catalogue continued morphological change, as well as begin to determine the recommended
timescale of extended post project assessments. Results catalogue a continuing trend towards deep pool formation at engineered LWD structures, and show previously undocumented naturally forming LWD structures within the reach. Consistent with previous studies, the LWD structures continue to encourage increasing channel complexity in the longitudinal profile, consistent with quality salmonid habitat. Continued monitoring has begun to show changes in lateral complexity occurring on a longer timescale than that of vertical pools and riffles, as shown by an engineered LWD structure causing the formation of a
significant meander and backwater. Riparian vegetation continues to thrive, as establishment along the gravel bars, banks, flats, and floodplains of the reach matures and increases. Results show the importance of long term monitoring in tracking the long-term development of creek restoration projects.

 

Evolution of Restored Wetlands on Twitchell Island in the Sacramento-San Joaquin Delta (Madeline Foster, Michael Levy, Bronwen Stanford)

Tidal marsh accretion rates are important both for carbon storage and capture and for the restoration of this habitat type. We investigated the impact of different management regimes on marsh accretion in the Sacramento San Joaquin Delta by 1) comparing accretion in the experimental wetland (West Pond on Twitchell Island) between the years with and without strict water level management and 2)
comparing accretion at this managed experimental wetland to a partially submerged, intertidal freshwater wetland with no management (Lindsey Slough on Liberty Island). To determine the accretion rate in West Pond since strict management ended, we resurveyed marsh surface elevation. We found that accretion rates at West Pond have increased without strict water management and
that accretion at West Pond is an order of magnitude greater than at Lindsey Slough. Our findings suggest controlled inundation is the favored strategy for restoration.
