Urban Native Plant Communities PREFACE: This manual serves two purposes.

First, it lists plants included in northwest native plant communities for urban areas in the Pacific Northwest. Second, it suggests design guidelines for use in preparing landscape plans using Pacific Northwest native plants. This manual does not give specific detailed information about individual plants, rather it assumes that the user has an understanding of plant identification, ecology, and planting procedures. For information about plant forms, sizes, and colors, other resources should be consulted. There are several very good sources of information about native plants, including: Gardening with Native Plants of the Pacific Northwest,

by Arthur R. Kruckeberg; Plants of the Pacific Northwest Coast, by Pojar/Mackinnon, Wayside Flowers of the Pacific Northwest; by Dr. Dee Strickler, Hortus Northwest, A Pacific Northwest Plant Directory & Journal; and Douglasii, a newsletter published by the Washington Native Plant Society. The Washington Native Plant Society may be contacted by writing: Washington Native Plant Society P. O. Box 28690 Seattle, WA 98118-8690 Plant sketches for this manual are based on photographs from Plants of the Pacific Northwest Coast, by Pojar/Mackinnon.

Urban Native Plant Communities INTRODUCTION: This manual contains guidelines for the use of native plants in the planning and creation of successful and aesthetically pleasing urban landscape designs.

For this document, Pacific Northwest "native" plants are those species that were established in the region before European settlement. The plants selected for this document are endemic to all areas from northern California to British Columbia and west of the coastal mountain ranges. This manual suggests procedures for successful native plant establishment based on the composition and dynamics of native plant communities. Assembling these groups of plants into native plant communities (urban ecological plant communities) is the fundamental basis for this manual. All of the plants listed here are suitable for cultivation by growers and nurseries.

substitute a mix of successional communities at the time of installation. This mix of successional plant communities represents a more natural plant pattern. Additionally, 0this design style also responds well to typical constraints of an urban setting: utility infrastructure, narrow planting strips, reflective heat from paved surfaces, etc. The designed successional native plant communities described in this manual include trees, shrubs, groundcovers, mosses and plant-fungi associations called mycorrhizae (See Diagram 1).

PROCEDURES: Native plant community succession in typical Northwest wilderness areas may require decades or even centuries to complete. Traditional urban landscape designs typically represent late successional stages.

Overgrown plants will be removed and replaced by new members with similar requirements, maintaining the original landscape design. Other earlier successional plant communities are generally discouraged, either chemically or through the use of plant-inhibiting mulches or sterile soil mixes. The alternative suggested in this manual is to

Roots

Mycorrhizae filaments

Mycorrhizae are anatomical structures resulting from the symbiotic association between a plant root and a fungus. These fungi are the single most important organisms living in a symbiotic relationship with living plants. Mycorrhizal structures encourage and enhance plant establishment. Mycorrhizal fungi must be present in the soil for optimal sustained growth and transplantability of most native plants.

Virtually all undisturbed topsoils contain mycorrhizal associations. The spores of the soil fungi needed to develop mycorrhizae will colonize most soils or soil mixes that have been in place for more than two growing seasons.

Most native and ornamental plants will grow well in mycorrhizal deficient soils as long as each plant’s water, light, and nutrient requirements are met through irrigation, fertilization, and soil amendments. However, some native plants will not grow at all if mycorrhizal fungi are not present.

In our Pacific maritime climate, the summer drought period may last for several months or longer. The native plants of this area have developed a complex relationship with mycorrhizal fungi which prevents soil from wicking water away from the roots of the host plant. Mycorrhizal structures benefit native plants primarily by surrounding and protecting plant roots from desiccation and improving the plants’ ability to take up nutrients.

Diagram 1 - Mycorrhizae

A Manual of Native Plant Communities for Urban Areas of the Pacific Northwest

Urban Native Plant Communities Mycorrhizal structures can store and make available to native plants up to seven times the moisture that would otherwise be available. The fibrous root-like structure of mycorrhizae also effectively extend the host plant’s root penetration into the soil. In the urban environment, mycorrhizal fungi are brought to a new planting site by: 1) inoculum on the plants’ roots, 2) direct application to the planting soil at the site, or 3) bringing in salvaged soil from a native soil site which already contains a variety of mycorrhizal fungi. Container soil should be inoculated at the time of propagation to ensure optimal establishment of container grown native plants. Inoculation is the least expensive way to ensure that mycorrhizal organisms will be transported to the planting site. Plants are inoculated by dipping young plants in a water solution that contains mycorrhizal fungi spores.

The cost for this method can be as low as $10.00 per 5,000 plants.

To assure successful establishment of native plants, the installer must ensure that either: 1) mycorrhizae are present in the soil; or 2) that the native plant communities receive the same degree of care (irrigation, soil amendments and fertilizer) usually given to ornamental plants.

The successful use of salvaged plants will require that: 1) a substantial amount of their original soil is taken up with the rootball, 2) mycorrhizae

inoculated soil is incorporated into thetransplanting container, or 3) a liquid mycorrhizal solution be applied to the soil at the time of planting. Native mosses, companion plants, and pioneer plants, all of which provide a living mulch, are also very important for successful native plant establishment. These plants buffer the impact of rain on the soil, hold water in a sponge-like fashion, slow run-off, minimize erosion, shield soil, plant roots, and small seedlings from the sun, and stabilize the plant community’s microclimate, specifically moderating it at the air-soil interface.

Salvaged plants should be obtained only through programs like King County's Native Plant Salvage Program. Make sure any nursery which attempts to sell salvaged plants obtains them only through a recognized plant salvage program. Make sure the plant salvager digs and transplants in a manner which minimizes stress on the plants. Many plants are salvaged and handled improperly, and these cannot survive for long.

(Exercise caution when using salvaged northwest native plants) Nursery-grown plants thrive more readily than plants dug in the wild. Salvaged or dug plants experience extreme shock when moved. In a natural setting plants will develop large root systems and important

interdependencies with other plants and organisms. When plants are salvaged, these relationships are severely impacted. Thus, it is preferable to use nursery-grown plants whenever possible. Long term plant survival is more likely when container-grown plants are used.

DESIGN: Preparing a design is more subjective than the process of assembling the necessary landscaping elements (including plants, soil, water and supplemental nutrients) on site.

Designing with native plants leaves plenty of room for individual artistic expression.

However, the process of native planting design requires inspection of any nearby undisturbed native plant com-munity. Existing woodlands, etc., yield many clues for plan composition, and plant community patterns that will be useful for developing a landscape plan. Purposeful order in the design of a native plant community plan is as important as functional considerations like screening and buffering. To develop an attractive plan, the designer should consider that the plant community will evolve over time. The designer, installer, client, and gardener should understand that parts of the new plant community will thrive initially, while other portions of the design will change as the plants adapt and adjust to site conditions. The guiding design principle for developing a native plant community is the clump-gap mosaic (see Diagram 2).

Urban Native Plant Communities succession (and native plant community composition) can be steered by: 1) shaping the topography to channel or impound water, 2) building berms to improve drainage, 3) changing the solar orientation, and 4) placing rocks, logs and snags to create plant micro-habitats. You can facilitate this successional pattern by the arrangement of trees, large shrubs, and mass plantings. The vision for garden aesthetics should allow for changes in, and evolution of, the plant

Diagram 2 - Clump-Gap Mosaic This principle requires adherence to the rule of diversity. Placement of plants in a clump-gap mosaic requires clumping individuals of one species together, then placing individuals of that same species away from the first group. As the process is repeated with different species, a mosaic pattern is formed. This pattern allows plants with specific growth requirements to find a suitable home within the plant community and either flourish or eventually disappear. The overlapping mosaic pattern improves the chances of developing a sustainable, multi-tiered covering of the ground. The path of

communities over time. The following listed plant communities include native plants that, with appropriate planting procedures, should have a high probability for successful growth in most urban conditions. Using these plant lists assumes a general acceptance and knowledge of site grading practices. Avoid uniform topography – even small variations in the topography will allow for the establishment of a more diverse plant community (See Diagram 3).

Shade by larger trees at the time of planting will improve conditions for shade loving plants, helping them grow and thrive.

Plant numerous small plants throughout the site.

The use of larger shrubs and trees at the time of planting modifies wind and shade patterns to shelter young plants.

Vary topography to capture water which will sustain plants requiring more moisture.

Boulders modify plant growing conditions by absorbing then radiating heat, and by collecting water at their edges.

Urban Native Plant Communities Both plant quantity and size are important in developing a successful native plant community.

Large plants tend to be harder to establish than small ones. However, it is important to use some larger plants to create a skeletal structure to modify environmental conditions for the new plant community. Smaller plants should be placed in less conspicuous places in the garden where they may thrive when environmental conditions improve. Many native plants have the ability to remain almost completely dormant under inappropriate growing conditions.

Because cost is usually a major consideration in a planting design, the use of a greater number of small plants and seeds is generally preferable to planting a few large individuals. This practice will also improve the chances of developing a successful and diverse ecological plant community that is well-adapted to a site (See Diagram 4).

Establishing a diverse native plant community will usually require the use of a seed mix.

Traditional methods for applying seed include hydroseeding, hand and mechanical broadcasting, and land imprinting. Of these methods, the direct application of seed to the soil is preferred. Land imprinting is a seed application method that applies seed and mycorrhizae directly to the prepared soil without using a mulch or tacifier. Broadcast seeding is suitable for smaller projects, while hydroseeding, mechanical sowing, and land

imprinting are best for large areas. Native plant seed mixes are best sown in the fall to take advantage of our winter and spring rains.

Another important part of encouraging the diversity of a native plant community is the exclusion of certain weedy species. When designing a native plant community, be very cautious that the species used are not going to

grow so vigorously that they will monopolize the garden. The most prevalent weedy species to remove and avoid include Scotch Broom, Himalayan Blackberry, English Holly, and English Ivy. Other species are also problematic, and research for design should explore problematic weedy species in any given area.

Sun loving plants are present throughout site.

Shade loving plants are also present.

Urban Native Plant Communities HOW TO USE THE PLANT LISTS: The following plants are recommended for use in urban landscapes. The first list is for plants that do well in sunny conditions. Many of these plants will also do well in partial shade conditions, and those are so noted. The second list is for plants which prefer more shade, and conversely, some of these plants will also do well in sunnier locations. There is overlap between the two situations since many native plants adapt to a variety of lighting conditions.

Plants given a “Highly Adaptable” rating in the Re ma rk s column will thrive in many different conditions.

Plants given an “Adaptable” rating have a special need or requirement in order to do well, or they may simply exist marginally within a certain plant community until conditions change to their favor. The “Requires” rating is for plants that require specific conditions to survive; these should be used with care and consideration. The third list includes plants recommended for use in very narrow planting areas. The fourth list includes grasses, sedges, and rushes; this list is included for use in meadow/grassland restoration projects or for designers who have a special interest in this plant group. The fifth list includes plants for wetland and riparian areas.

The sixth list contains all plants recommended in the manual, which nurseries should grow and make available to the public. Finally, the seventh list contains plants that, although native, can be very

aggressive and may virtually take over a small site. Plants in this list are important in restoration projects but should only be used with a full understanding of their potential impacts. These lists are not all-inclusive, and therefore the use of other native plants is encouraged.

Urban Native Plant List PLANT LIST 7 AGGRESSIVE OR VERY THORNY NATIVE PLANTS, TO BE USED WITH CAUTION

Some of these native plants can be very aggressive and virtually take over a small site – use caution and be aware of site limitations. All of these plants have great habitat and aesthetic value, and many are important early-successional species that are vital to creating healthy ecosystems. Plants on this list are important in restoration projects and projects on larger sites, but should only be used with a full understanding of their potential impacts.
