In these cases, the list of suitable species will be expanded, but it is important to consider available moisture and flooding patterns. Trees and shrubs vary in their ability to survive flooding (Table 1). It is important to remember that the ability of a tree to survive flooding also will depend on soil type, soil structure, time of flooding, and the condition of the trees before flooding. Final species and planting design decisions should be based on the objectives of the landowner and the recommendations of a natural resource professional. Figure 2.

    Diablo Firesafe Council The following list of plants contains those found in the references that were recommended for use in fire prone environments by at least 3 references. All of the plants listed here were given either a high or moderate fire resistance rating in the references where a rating was assigned, or found listed in the references that categorized plants as fire resistant without assigning a degree of resistance. In most cases, the terms used in the ranking were not defined, and if they were, there is no agreed upon standard definition. For this reason, the plants are listed in this chapter without any attempt to rank them. The list is sorted by plant form -- groundcovers, shrubs, trees, etc. Some species may appear twice (e.g. once as a groundcover and then again as a shrub) because they have properties attributed to both forms. For a complete description of the plant, including its mature characteristics, climate zones, and information on erosion control and drought tolerance, please refer to Chapter 4, the landscape vegetation database. It is important to note that a plant's fire performance can be seriously compromised if not maintained. Plants that are not properly irrigated or pruned, or that are planted in climate areas not generally recommended for the plant, will have increased fire risk and will likely make the mature plant undesirable for landscaping in high fire hazard zones. Table 1. Plants with a favorable fire performance rating in 3 or more references. Some plants may have invasive (indicated as ), or other negative characteristics that should be considered before being selected for use in parts of California.

  • Nannyberry (Viburnum Lentago)
    BWSR Featured Plant Name: Nannyberry (Viburnum lentago) Plant Family: Caprifoliaceae Statewide Wetland Indicator Status: Great Plains – FACU Nannyberry is a shrub that is both beautiful and Midwest – FAC versatile. This shade-tolerant, woody plant has flat N. Cent. N. East – FAC topped white flowers, fruit that is used by a wide variety of birds and wildlife, and vibrant fall color. Frequently used as a landscaping plant, it is successful as a tall barrier and wind break. Its ability to function as both a small tree and multi-stemmed shrub and ability to adapt to many environmental conditions makes it well suited to buffer planting and other soil stabilization projects. Flat-topped flower clusters and finely serrated leaves Identification This native shrub can be identified by its pointed buds, unique flowers, and fruit. Growing to around twelve feet tall in open habitats, the species commonly produces suckers and multiple stems. The newest branches are light green in color and glabrous and buds narrow to a point. With age, the branches become grey, scaly and rough. The egg-shaped leaves are simple and opposite with tips abruptly tapering to a sharp point. Leaf surfaces are shiny, dark green and hairless with reddish finely serrated margins. Fall color is a vibrant dark red. Numerous dense, flat-topped flower heads appear and bloom from May to June. Flowers are creamy white and bell to saucer-shaped. The flowers develop into elliptical berry-like drupes that turn a blue-black color from July to August. The Multi-stemmed growth form sweet and edible fruit is used by a variety of wildlife species but has a wet wool odor when decomposing, thus its alternate name – Sheepberry.

  • What Is a Shrub?
    What is a shrub? The man behind the beverage counter at the festival asked me if I ever had a great shrub. With questioning eyes, I imagined that beautiful green evergreen that grows outside our house. I guess he knew that I had no idea why he was asking me that question since he started to laugh as he explained that it is fruit syrup preserved with vinegar and mixed with water or alcohol to create a very refreshing drink. It seems that this is an old fashioned idea that was used to preserve seasonal fruit, creating fresh flavored syrup that can be used for beverages, salad dressings, or meat glazes. Adding vinegar to water helped make it safe to drink for Babylonians and even Romans made a beverage like this called posca. Early colonial sailors carried those vitamin C enhanced shrubs to prevent scurvy. Many older cookbooks or well as some recent ones have recipes for shrubs. As I researched shrub recipes, I found several different methods. Most of them involved creating fruit-flavored vinegar and adding sugar to it. The vinegar acts as the preserving agent, allowing fresh fruits to turn into flavorful syrups. The ingredients are simple: Fresh fruit, vinegar, and sugar Fruits - Think berries, peaches, plums, pears, cherries and many other fruits, just make sure they are wonderfully ripe and sweet. The fruits need to be washed, peeled, chopped, or lightly crushed. Some additions can be ginger, citrus peels, or even peppercorns. Vinegar – you can use distilled white vinegar, apple cider vinegar, or even wine vinegars.

  • Nr 222 Native Tree, Shrub, & Herbaceous Plant
    NR 222 NATIVE TREE, SHRUB, & HERBACEOUS PLANT IDENTIFICATION BY RONALD L. ALVES FALL 2014 NR 222 by Ronald L. Alves Note to Students NOTE TO STUDENTS: THIS DOCUMENT IS INCOMPLETE WITH OMISSIONS, ERRORS, AND OTHER ITEMS OF INCOMPETANCY. AS YOU MAKE USE OF IT NOTE THESE TRANSGRESSIONS SO THAT THEY MAY BE CORRECTED AND YOU WILL RECEIVE A CLEAN COPY BY THE END OF TIME OR THE SEMESTER, WHICHEVER COMES FIRST!! THANKING YOU FOR ANY ASSISTANCE THAT YOU MAY GIVE, RON ALVES. Introduction This manual was initially created by Harold Whaley an MJC Agriculture and Natural Resources instruction from 1964 – 1992. The manual was designed as a resource for a native tree and shrub identification course, Natural Resources 222 that was one of the required courses for all forestry and natural resource majors at the college. The course and the supporting manual were aimed almost exclusively for forestry and related majors. In addition to NR 222 being taught by professor Whaley, it has also been taught by Homer Bowen (MJC 19xx -), Marlies Boyd (MJC 199X – present), Richard Nimphius (MJC 1980 – 2006) and currently Ron Alves (MJC 1974 – 2004). Each instructor put their own particular emphasis and style on the course but it was always oriented toward forestry students until 2006. The lack of forestry majors as a result of the Agriculture Department not having a full time forestry instructor to recruit students and articulate with industry has resulted in a transformation of the NR 222 course. The clientele not only includes forestry major, but also landscape designers, environmental horticulture majors, nursery people, environmental science majors, and people interested in transforming their home and business landscapes to a more natural venue.
