When river restoration practitioners talk about the most significant challenges they face in project development and implementation, the topic often turns not to design or construction, but rather to regulations and permitting. Practitioners have typically viewed regulations as barriers to implementation, rather than tools to improve project quality. Because of federal and state laws, stream restoration projects must have a stack of permits prior to construction – everything from a 404 permit, to a Biological Opinion, to state fish passage approval – yet the agencies tasked with natural resource management want to encourage and support stream restoration. To this end, streamlining tools intended to get good restoration on the ground, while also reducing permitting uncertainty and approval timelines, have been developed.About the Speaker:Janine Castro is a geomorphologist for both the US Fish and Wildlife Service and National Marine Fisheries Service in Portland, Oregon. Her primary duties include developing streamlining and review tools to improve stream restoration implementation and effectiveness, providing technical assistance on stream restoration projects, evaluating state and federal permit applications for instream work, and coordinating between state and federal agencies on controversial issues related to fluvial geomorphology, such as instream gravel mining, navigation, and energy transmission lines. Janine also provides national and international training on geomorphology, stream restoration, and public speaking for scientists. Janine has worked for the Fish and Wildlife Service for 13 years and spent the preceding 10 years working for the Natural Resources Conservation Service.

Restoration of natural processes is a primary goal and focus of design in many stream restoration projects. For a variety of reasons, these approaches are expected to provide more effective and resilient ecological benefits at a lower cost over the long term. The technical framework and practical guidance for process-based approaches has been evolving rapidly through both science and practice. Much recent work on stream functions in developed areas has focused on hydrologic influence “up the pyramid” to geomorphology, water chemistry and ultimately biology. However, biological elements in the form of native vegetation and American beaver can also be major drivers of natural systems to reduce the impact of altered hydrology, create diverse habitats and improve water quality.About the Speaker:Bruce Roll began work at Clean Water Services in 2007 as Watershed Management Director. Before that, he was the Assistant Director for Whatcom County Public Works in Washington for eight years, overseeing Watershed Management, Salmon Recovery, Marine Resource, River and Flood and Solid Waste Programs and he was the Director of Water Resources and Laboratory Services for five years at the Portland Water District in Portland, Maine. He has served as a peer reviewer and technical consultant for the American Water Works Association Standard Methods Committee and the American Water Works Research Foundation. He was actively involved in the development of the Puget Sound Salmon Recovery Plan, where he was appointed to the Shared Strategy Steering and Oversight Committee. He received a BS in Environmental Microbiology from Colorado State University, a MS and PhD from the Water Resource Research Center at the University of Hawaii, and a MPH in Management from the School of Public Health.

Urbanization may block dispersal of native wildlife and plants at a critical time when climate change may require many organisms to shift their ranges. The Washington-Multnomah-Clackamas county area urban development is becoming contiguous from the Coast Range to Cascade Range. The network of riparian corridors, parks and natural areas within the urban area is essential for many species to begin needed movements and range shifts. However, organisms requiring open habitat will not be served by wooded corridors and patches. For them, urbanization's east-west extent may be a barrier to northward range shifts. Improvements in open habitats such as power line corridors may increase permeability for open country wildlife. Metro and partners are taking this approach with the Westside Trail, which follows a north-south power line corridor for approximately 12 miles from the Tualatin River to the Willamette River near Sauvie Island.About the Speaker:(1) ELAINE STEWART is a Senior Natural Resources Scientist with Metro. She serves as project leader for natural area restoration projects, managing and overseeing feasibility analyses, project scoping, development of project funding, project implementation and evaluation of project effectiveness. Her ecological restoration projects encompass nearly every ecosystem in the lower Willamette Valley.

Portland Urban Meadowscaping Pilot (PUMP) is a collaborative effort to develop lawn replacement recommendations to increase storm water infiltration and wildlife habitat in Portland's urban landscape. As homeowners become more aware of the environmental impacts of their landscape choices, naturescaping programs are receiving more requests for lawn replacement options. Although common, lawns provide little benefit to storm water infiltration, water quality, or wildlife habitat and require polluting inputs such as fertilizers and mowing. The goal of PUMP is to provide public education, technical support and assistance with the planning, planting and monitoring of meadowscapes on residential landscapes and in public parks to increase wildlife habitat and stormwater infiltration in the urban realm.About the Speaker:Mary Logalbo has been working as a conservation planner with Soil & Water Conservation Districts in Oregon for the past seven years with an emphasis on native plant restoration, invasive species control and environmental education. Mary received her Bachelor of Science in Environmental Science from Plattsburgh State University (PSU) in northern New York. She had the opportunity to study abroad in Queensland, Australia and completed research projects on the Great Barrier Reef and tropical rainforests of Cairns. After graduating from PSU, Mary worked as the Executive Director of the Au Sable River Association (ASRA), a non-profit watershed organization. Mary also served as a Technical Research Specialist for the Northwest Service Academy’s AmeriCorps program and has worked on biodynamic organic farms. Mary currently works as the Urban Conservationist with the West Multnomah Soil & Water Conservation District and coordinates the District’s invasive species and urban habitat restoration programs. When Mary is not at work she can be found enjoying the great outdoors on her bike, skis, raft or gardening in her yard.
Using evolving data sets and a GIS model to create a living Natural Resources Master Plan for restoration in the City of GreshamDate:Friday, May 3, 2013Time:12:15 to 1:00 pmLocation:Metro, Room 370 A/B, 600 NE Grand Ave, Portland, ORSpeaker:Kathy MajidiAffilitation:City of Gresham, Department of Environmental Services
In an effort to more systematically track restoration needs and inform restoration investment decisions, the City of Gresham's Natural Resources Program developed a "living" Natural Resources Master Plan that continually incorporates new survey data to update prioritization of protection and restoration needs for wetlands, streams, and publicly owned natural areas within the current city and future annexation areas. The master plan structure provides a method for comparing opportunities across the three watersheds in Gresham, and for comparing opportunities within a particular watershed. This GIS-based restoration planning approach maintains a current natural resources inventory and needs assessment, updated as new digitized data are created.About the Speaker:Kathy Majidi has been with the City of Gresham’s Department of Environmental Services for 12 years, in part working to understand and convey the value of local urban habitat resources in the context of larger-scale conversation planning decisions. She has built partnerships with resource agencies, neighboring jurisdictions, volunteers, community groups, and non-profits to catalogue and track species, habitat, and stream conditions to inform public policy decision-making. She initially worked with Gresham GIS staff, AmeriCorps volunteers, and consultants to create a GIS-based model for prioritizing riparian areas for revegetation needed to reduce local stream temperatures, and has continued since to increase use of GIS modeling and spatial biodiversity and stream survey data in scoping and prioritizing stream and wetland restoration projects.

Freshwater mussels are the most at-risk animals in North America. Although they play critical ecological roles in aquatic habitats and their life history is closely tied to native fish, relatively little is known about mussel populations in the Northwest. The role of urbanized watersheds as a refuge has not been generally assessed and reproductive status and connectivity of populations in Portland-area watersheds is unknown. Xerces Society, Johnson Creek Watershed Council, and City of Gresham used volunteer-based surveys to conduct an extensive assessment of freshwater mussels in Johnson Creek and selected tributaries. Despite multiple impairments, the watershed supports substantial numbers of western pearlshells (Margaritifera falcata) and floaters (Anodonta). Most are older and of similar age cohorts, but young mussels were also found. The upper watershed has more and larger mussel beds, but mussels persisted in some more degraded reaches in the lower watershed.About the Speaker:Celeste Mazzacano is the Staff Scientist and Aquatic Program Director for the Xerces Society for Invertebrate Conservation. She is also the Project Coordinator for the Migratory Dragonfly Partnership and Editor in Chief of Argia, the news journal of the Dragonfly Society of the Americas. She has a PhD in Entomology from the University of Minnesota, and has over 17 years of experience in education, conservation, and research, including extensive work in stream and wetland invertebrates, natural resource education and citizen science, and surveys, status reviews, and management plans for rare and threatened aquatic invertebrates.

The increasing popularity of ‘adaptation’ calls for an examination of flexibility and change within environmental planning and governance. This presentation shares preliminary analysis from a comparative study of urban biodiversity governance in Portland, Oregon and Brisbane, Australia. The study examined the role of flexibility in changes to environmental governance in both cities over the period 1991-2011. The research entailed interviews with actors in both cities and analysis of organizational and policy documents. Preliminary analysis has revealed that formal processes for change - such as adaptive management - were most clearly present in smaller-scale changes. Formal processes that influenced large-scale shifts tended to be those that contributed to the argument for change (e.g. mapping projects) or influenced the way large-scale shifts were implemented (e.g. participatory forums).About the Speaker:Paul is a Doctoral Student and Teaching Assistant in environmental planning and governance at the University of Queensland, Brisbane Australia. He was a visiting scholar at PSU’s School of Urban Studies and Planning in 2011. His research interests include environmental planning and US-Australia comparative research with a focus on environmental governance. Previous to his studies, Paul coordinated community sustainability projects in Australia for more than 15 years. He has an Honours degree in environmental management from the University of Queensland. His PhD research, which is due for completion in 2013, is supported by the Climate Adaptation Flagship within the CSIRO (Australia’s national science organization).

In 2008, the City of Portland Environmental Services bureau embarked on an ambitious tree-planting effort with city, state, and nonprofit partners. Three years in, this Grey to Green initiative has helped plant two-thirds of the 26,000+ newest members of Portland’s urban forest. These trees will help improve community livability and watershed health while contributing to clean rivers and the city’s 33% tree canopy cover goal. Post-planting monitoring programs help measure program success and provide the basis for estimating future canopy benefit from today’s planting investment. Trees planted by Friends of Trees (FOT) volunteers were inspected by FOT volunteers twice during the summer following planting. Trees planted by city contractors were assessed by city staff in late summer for two years following planting. Data collected include species, planting location, site conditions, and condition rating.

In an urban environment new invasive species threats may go overlooked. But occasionally non-native species do get reported, and follow-up occurs. During the summer of 2011 a large bloom of magnificent bryozoans (Pectinatella magnifica) was spotted in Vancouver Lake and reported to Washington State University-Vancouver by the concerned citizens. Subsequent discussions and interviews with natural resource agencies and partner organizations throughout the Pacific NW were held to better understand the threat of P. magnifica as a potential invasive species. Those discussions have uncovered a plethora of anecdotal evidence, leading us to believe this rare non-native bryozoan may not be as rare as U.S.G.S. reports in their Nonindigenous Aquatic Species (NAS) database. Records outside of its native range, east of the Mississippi river, are only within the last two decades. Early recorded occurrences place P.About the Speaker:If you met Briita Orwick one year ago, you would have likely found her working onboard a commercial fishing vessel with NOAA Fisheries, or hiking though coastal streams conducting spawning surveys for ODFW.

English Ivy (Hedera helix orH. hibernica) is an aggressive evergreen vine and is the target for removal in restoration sites in the Pacific Northwest. Ivy smothers groundcovers and climbs to the canopy of trees, dampening the regeneration of trees and weakening mature trees through disease and weight. Seven permanent test plots (.1 acre each) tested herbicide applied at different seasons and compared it to hand pulling and a control at Rocky Butte. Data showed that summer was the most effective time to spray herbicide and after 2 sprays and 3 years, cover of ivy dropped from 100% to 21%. Spring and winter sprays were least effective, showing 70% and 73% ivy cover respectively after 3 years. Two fall spray plots were initially successful, but after 2 years, ivy increased in cover (final ivy cover 31% for Plot C (glyphosate mix), 88% for Plot D (2% triclopyr Year 1, and mix Year 2)).About the Speaker:Toby Query has worked as an ecologist for the City of Portland's Watershed Revegetation Program since 1999. He manages restoration activities on various natural areas and also coordinates plant propagation and installation for the program, in which over 3 million native trees and shrubs have been planted. Prior to his time at the City, he has studied Spotted Owls, Great Green Macaws, and Indigo Buntings.

Oregon slender salamanders in Gresham: implications for the value of remnant habitats within urban centersDate:Friday, April 1, 2011Time:12:15 to 1:00 pmLocation:Metro, Room 370 A/B, 600 NE Grand Ave, Portland, ORSpeaker:Laura GuderyahnAffilitation:City of Gresham - Environmental Services, Phone: (503) 618-2246, Email: email@example.com
Geographic distribution and specific habitat requirements of the Oregon Slender Salamander (Batrachoseps wrightorum) remain poorly understood; however, it is thought to be endemic to the west slopes and crest of the Oregon Cascade Range and is associated with late-successional Douglas-fir forests and talus slopes. Specifically, these salamanders are predominantly found inside large-diameter (min 50-70cm dia), well-decayed logs and under decaying bark slabs. However, in 2007, two separate populations were found among non-native plants and small debris in narrow riparian buffers in suburban residential developments in Gresham, Oregon.About the Speaker:Laura Guderyahn is the Watershed Restoration Coordinator for the City of Gresham, Oregon. In her position with the City, she manages 25-30 restoration sites each year throughout Gresham's public natural areas as well as on high priority private streamside properties through partnerships with landowners. Laura also coordinates biodiversity surveys for the City, including bird, small mammal, freshwater mussel, amphibian, and reptile monitoring.

In order to efficiently reduce toxic loading to the Columbia River basin, sources and pathways need to be identified. Little is known about the toxic loadings coming from wastewater-treatment facilities and stormwater runoff in the system. This study provides preliminary data on these sources and pathways throughout the basin. The cities sampled in Oregon and Washington were chosen for their diverse characteristics, including population density. Samples were collected from a wastewater-treatment facility in each of the cities and analyzed for wastewater-indicator compounds, pharmaceuticals, PCBs, PBDEs, organochlorine or legacy compounds, currently used pesticides, mercury, and estrogenicity.About the Speaker:Jennifer Morace completed a bachelor of science in chemistry at Linfield College and a masters of science in environmental science and engineering at Oregon Graduate Institute. She has been with USGS since 1991 and has worked on many water-quality studies in the Columbia, Willamette, Yakima, and Klamath basins. Her current work and interests focus on evaluating water-quality conditions in the Columbia River Basin, particularly "toxics"--pesticides, legacy compounds, pharmaceuticals, wastewater compounds, PBDEs, and emerging contaminants.

Three types of low-impact development (LID) rainwater detention structures were tested using simulated storms and ambient rainfall spanning both dry and wet seasons. The structures included stormwater planter boxes (n=12), extensive ecoroofs (n=2) and a 93 m2 section of porous pavement. Planter boxes varied with respect to soil depths (n=2), soil mixes (n=2) and the use of a fabric filter, resulting in 6 unique planter box types, each with 2 replicates. Results showed that water retention varied from 0% to 59% for the stormwater planter boxes over 72 separate storms, with a median retention of 20%. Lag time between the centroids of input and output flow varied from 1.7 min to 29.9 min, with a mean lag time of 12.8 min. In general, planter box configurations with a finer, less porous soil mix with no fabric filter produced the largest stormwater retention and the longest delay in transmission of stormwater.

The western pond turtle (Actinemys marmorata marmorata) and western painted turtle (Chrysemys picta bellii) are designated critical on the Oregon state Sensitive Species List. Both are threatened by habitat loss and degradation, especially in urban environments where there are increased threats to their survival. This project addresses conservation issues surrounding native turtles in the Portland, Oregon. A methodology to evaluate the presence of turtle habitat was developed after extensive literature review and consultation with regional habitat managers. The methodology was then tested on 36 public and privately owned sites within and adjacent to the urban growth boundary (UGB) to critique its usability and determine if turtle habitat is still intact within the UGB. Tested sites were those listed in a database of turtle sightings compiled by Metro, Portland‘s regional government and reported to various agencies within the past 40-50 years.

This project examines the developmental changes occurring in wildflowers at Cooper Mountain Nature Park. The goal is to successfully implement a program to monitor and collect rare wild flowers for the Metro Native Plant Center. The project began as our Americorps Community Action Project, CAP, through NWSA. Our “Bloomtime Project” aids in the Native Plant Center’s vital seed saving and amplification process by tracking the phenological developments for native flowers at Cooper Mountain. We tracked changes in phenological events involving plant flowering; with observations of interest ranging from first bud, flowering, seed formation, to seed dispersal. We created a straightforward data collection formula with codes assigned to each species, site, and phenological state. Cooper Mountain is a unique habitat with Oregon White Oak savannas and open prairies that have been relatively undisturbed for hundreds of years.

The City of Portland is conducting an assessment to determine status and threats of invasive animals and to identify and guide management actions. This assessment will characterize invasive animals in the City of Portland; evaluate existing programs and regulatory authorities; define opportunities for collaboration; and identify high priority projects for implementation. The assessment will identify invasive terrestrial and aquatic wildlife species that are currently present, as well as those that might invade suitable habitats in the City in the next 5-10 years. The assessment includes a survey to gather input from regional experts. This work is being conducted as part of the larger statewide assessment of invasive species being conducted by the Oregon Invasive Species Council, and will address high priority tasks identified in the Portland Watershed Management Plan and the City's Terrestrial Ecology Enhancement Strategy.

An estimated 100 million to 1 billion bird deaths occur worldwide annually as a result of window strikes, a mortality rate second only to habitat destruction. Numerous cities have documented large numbers of both daytime and nighttime collisions with windows on glassy buildings. No study has ever measured the magnitude of this occurrence in Portland, and our urban landscape is undergoing rapid changes, with new architecture trending toward taller, glassier structures. An increasing body of research has begun to identify building designs that reduce incidence of bird collisions, and experts suggest incorporation of these designs into LEED certification standards. Portland is poised to join a growing list of cities that require implementation of wildlife friendly building design in the planning process.

The Oregon Department of Transportation (ODOT) constructs projects to ensure a safe and efficient transportation infrastructure. Typically, projects consist of road improvements, new road construction, bridge upgrades, bridge replacements, and new bridge construction. Although avoiding and minimizing impacts to natural resources are integral to ODOT's design considerations, some projects result in impacts to jurisdictional waters of the U.S. and State. Pursuant to environmental permit requirements, ODOT implements mitigation for a wide range of impacts. The overall mitigation goal is to replace the wetland or waters functions that are lost or impaired due to project construction. In the spring of 2009, the ODOT Wetlands Program pursued a strategic learning opportunity by evaluating the post-monitoring period conditions of 29 "legacy" mitigation sites ranging from 8 to 17 years since mitigation construction.

We hypothesized that Douglas-fir trees (Pseduotsuga menziesii) standing apart from other trees (‘open-grown’) will intercept and evaporate a larger volume of water than Douglas-fir trees standing near other trees (‘closed-canopy’). Existing literature suggests Douglas-fir in Northwest forests intercept approximately 25% of incident rainfall annually, but says little about open-grown, urban trees.About the Speaker:Mitchell Bixby, Portland State University - Environmental Sciences, PO Box 751, Portland, OR 97207.

Environmental restoration projects are often designed and implemented without an integrated, process-based framework for successful project delivery. Much of the available research on ecological restoration is so narrowly focused that results are difficult to apply to actual projects. The recently published Sediment Source Control Handbook was developed through a collaborative effort over the past 6 years by a consortium of ski areas, regulatory personnel, researchers and restoration practitioners to address this disconnect between research and implementation.About the Speaker:Kevin Drake is a restoration planner and associate with Integrated Environmental Restoration Services in Tahoe City, CA. Kevin has seven years of experience in environmental and land use planning, watershed assessment, and restoration project design and implementation in California and Oregon. Kevin has a BS in Forest Ecology from the University of Montana and a Masters in Urban and Regional Planning from Portland State University. He has worked in both the public and private sectors on projects ranging from development of sediment load reduction strategies for the Lake Tahoe TMDL to the design and oversight of large-scale restoration projects. Kevin draws on his experience in environmental science, planning and on-the-ground restoration to develop integrated approaches to watershed restoration that bridge the gap between researchers and practitioners. Kevin is co-author of the Sediment Source Control Handbook and managed all aspects of this multi-year project, from field work through document development.

The City of Portland has implemented a habitat enhancement project to
remove the decommissioned sewer pipe that was exposed in Stephens Creek
near the confluence with the Willamette River. The project involved
installation of large wood and soil lifts to restore the banks of the
disturbed areas. The project also created off-channel habitat in the
remnant Stephens Creek channel on site. Project implementation helps the
City meet the goals for salmon recovery and terrestrial wildlife
enhancement as described in the Portland Watershed Management Plan.

Northern pygmy-owls (Glaucidium gnoma) are anecdotally considered habitat
generalists, and to date only a single study has yielded clues about their
habitat use and home range size. A multitude of unsupported, secondary
sources persistently avow that Northern pygmy-owls avoid unbroken, dense
forest, are associated with forest edges and open forests, and may indeed
benefit from logging. We investigate whether Northern pygmy-owls select
nest-site habitat non-randomly, and discuss preliminary findings on more

Urban streams present unique challenges for society because they can both impact and benefit the surrounding communities. They flood as well as provide access to the natural environment. Adaptive management holds the best hope for managing these complex stream systems.About the Speaker:Dr. Booth moved to Washington State in 1980, and he has worked on stormwater issues in the Pacific Northwest since 1985. He was one of the founding members of the USEPA award-winning King County Basin Planning Program, which successfully completed watershed management plans for many of the County’s unincorporated (and much of its incorporated) area, including most of its streams of highest resource value. From 1995 until 2006 he was a professor at the University of Washington, holding the position of Research Professor with joint appointments in the departments of Civil & Environmental Engineering and Earth & Space Sciences. He retains an active position as Affiliate Professor in both departments and is the senior editor of Quaternary Research, an international scientific journal for interdisciplinary studies of the last 2 million years of human and earth history. He joined the environmental consulting firm Stillwater Sciences in 2006 as a geologist and became its president in July 2007. He is licensed as both a professional geologist and professional civil engineer. Derek’s first article on the effects of urban-modified flows on stream channels was published in 1989; he has continued to study urban streams for the last two decades with a particular emphasis on changes in channel morphology as a result of hydrologic and sedimentologic changes. He also takes an active interest in how we can improve our management of, and coexistence with, these dynamic systems. He currently provides technical support for a variety of urban and suburban watershed studies, primarily in the Pacific Northwest. He is also member of the National Research Council committee that has recently reviewed the NPDES permitting system nationwide and is coauthor of the committee’s report, “Urban Stormwater Management in the United States” (release date 10/15/08); he has also coauthored the recent report to the Washington State Legislature from the University of Washington’s Climate Impact Group on the effects of future climate change on stormwater infrastructure.

Climate variability has significant influence on water quality through changes in the amount of runoff and pollutant concentration. The impact of climate variability on water quality is not well understood, particularly in urban streams. We analyzed the effects of hydroclimatic variability on water temperature and dissolved oxygen in streams of the Portland metro area. Multiple regression models were used to explain the variations in water quality as a function of flow and air temperature. The residuals of air temperature were used to control the correlation between flow and air temperature.About the Speaker:Heejun Chang is an associate professor of Geography at Portland State University, Portland, Oregon, USA where he teaches courses in hydrology, climate and water resources, global water issues and sustainability, GIS for water resources, and spatial quantitative analysis. His research areas include impacts of climate variability and change on regional water resources, land cover change and water quality, use of geospatial technology for hydrology and water resources, and urban flooding. His recent publications appear in such interdisciplinary, international journals as Climate Research, Hydrological Processes, Journal of Environmental Management, River Research and Applications, Science of the Total Environment, and Water Research.

This summer I conducted surveys on amphibians in 21 natural areas in Portland, OR. This project had three main questions: 1) What amphibian species live where in Portland, and with what densities? 2) What factors are influential for each amphibian species? 3) How can we effectively conduct habitat conservation and restoration for amphibians? To do this, I surveyed each of 59 ponds several times for amphibians and for each of 21 factors that are likely to affect amphibians. These factors included physical and chemical parameters of the pond and the surrounding area.About the Speaker:Katie Holzer is a recent graduate of Lewis & Clark College with a degree in Biology. Her thesis focused on amphibian conservation concerning barriers to movement and new pond colonization. She is currently conducting amphibian research with the City of Portland.

Increases in population and density often result in private development types that stress city ecologies. However, there is tremendous potential for designers in collaboration with the environmental science community to engage in private development projects that support the needs and aspirations of people while providing habitat for nonhuman species. Such ecologically-minded approaches redefine "sustainable urban development." Portland is poised for robust economic growth and the preservation of an outdoors-oriented quality of life.

Natural area managers must balance public access and habitat protection. The very attributes that make a site attractive to the public may be deleteriously affected by excessive public use. This balancing act is often performed in the absence of data that would help managers identify whether, and to what extent, habitat use by wildlife is affected by public use. We sought to determine whether habitat use by songbirds inhabiting riparian forests differed in areas with and without public trails. We conducted avian surveys with a standard point count protocol in 2006 and 2007.About the Speaker:Elaine Stewart is a Natural Resources Scientist with Metro Parks and Greenspaces. She conducts habitat restoration projects and manages natural resources on recently acquired public open spaces and open parks such as Smith and Bybee Wetlands Natural Area.

Six years of landscape level efforts to control Japanese, giant, bohemian, and himalayan knotweeds in the Sandy River basin have resulted in 90+ percent reductions in stem count, eradication of knotweed on over half of the sites it once populated, and a great appreciation for the plant's ability to survive. The results of herbicide treatments on knotweed vary greatly from site to site. Those plants that persist after 7 years of treatment are small, stunted, and unhealthy. Repeatedly treating such regrowth has produced virtually no measurable results.About the Speaker:Jason Dumont has been conducting habitat restoration projects for TNC for 4 years.
