A primary objective in many wetland restoration projects is to establish vegetation that is similar in structure and composition to natural wetlands. Plant species lists developed from local reference wetlands are used as guidelines for desired vegetation in the project wetland. If the existing vegetation on the project site does not have adequate numbers or abundance of desired species, additional vegetation must be obtained. The two basic sources of wetland vegetation are commercially grown plant material and native plant material collected from naturally occurring populations. There are benefits and drawbacks for each plant material source. The project manager must consider many factors such as availability and cost of obtaining the plant material when deciding which source is appropriate for the wetland restoration project. While information about commercially grown plants is readily available from the industry, relatively little guidance exists for use of native plant materials. The objectives of this report are to discuss conditions under which it is appropriate to use native sources of plant material and to present three case studies that demonstrate techniques for collecting and establishing wetland vegetation from natural sources in wetland restoration and establishment projects. Information about substrate preparation, hydrology, and other aspects of wetland restoration projects is beyond the scope of this report, but is available from sources such as Soil Conservation Service (SCS) (1992), Hammer (1992), and the forthcoming wetland engineer manual.

The Willamette Valley was historically dominated by three types of wetlands: wet prairies, shrub/scrub, and forested. As a consequence of drainage for agriculture and urban development, most of these diverse wetlands have been lost. Restoration of native wetlands is limited by a lack of knowledge about native plant species' growth and establishment requirements. This report presents results from four investigations of establishing wetland vegetation native to the Willamette Valley. In the first study, Pest Plant and Seed Bank Reduction (Chapter 2), three site preparation techniques were applied to a disturbed wet prairie that contained exotic species. The objectives of the study were to determine (a) whether the treatments reduced pest plant abundances for more than 1 year, (b) if treatments also reduced native plant species, and (c) whether treatment effects were consistent among years. Tilling with fall owing and solarization (heating under plastic) were generally found to be more effective than burning at reducing existing plants. Native plants were affected by all treatments. Although each treatment was effective at reducing at least one exotic plant species, none of the treatments were generally effective at controlling pest plants. This may have been due to cool, dry weather conditions during the treatments that were not conducive to seed germination. The authors conclude that site treatments should be applied for more than 1 year, and native plant materials should be planted as soon as possible to outcompete the recovering exotic species.

This report explains the process involved when proceeding from a wetland mitigation design concept to a fill' engineering package that is suitable for public bid and advertisement The information provided is geared toward educating nonengineering professionals engaged in developing wetland mitigation specifications The biological foundations for the various elements are first presented, followed by full guideline specifications. The vegetation specifications address site preparation, plant material acquisition, transport, handling, and storage of seeds, herbs, and saplings, planting methods for various stock types, different seeding methods, tiring of planting in conjunction with seasonal variations, hydrological considerations such as tidal cycle, water level and rainfall patterns, equipment access and type, protection measures for herbivory, inundation and vandalism, fertilization and amendrnent application, soil-nutrient testing, substrate handling, trppsport, and storage and minimization of impacts on existing wetland resources. The subgrade specifications target construction methods and equipment, soil-material testing, and performance. The other soil-related specifications quarantine and safeguard existing resources such as friable surface soils and wetland topsoils that can be used to "seed" a site.
