  • Northstar Fire Department, Fire Resistant Landscaping Plant List
    Northstar Fire Department, Fire Resistant Landscaping Plant List Many common plants naturally resist fire and can even slow its spread. In general, irrigated and well maintained leafy plants burn slowly. By replacing highly flammable vegetation with these fire resistant recommended species, you can significantly improve the statistical survivability of your home when a wildfire threatens. Courtesy of the “Villager Nursery” in Truckee, this list of fire resistive plants should be considered when enhancing or adding landscape. Here are some other key components to remember when selecting appropriate fire resistant landscaping plants. Choose plants that don’t produce much litter such as dead branches and twigs Plants that produce oils, resins or waxes should be avoided When planting from the approved list, appropriately space plants to prevent fire spread Never plant under conifer trees, this can create a ladder effect which allows smaller ground fires the ability to transfer into larger trees creating crown fires To help ensure their fire resistance, plants must be maintained, watered, and pruned. Routine care will provide you with an attractive defensible space landscape and help ensure the survival of your property in the event of a wildfire. Northstar Fire Department enforces both State and District fire codes that may directly affect your landscape. Northstar Fire Department recommends that prior to changing your landscape you consult with us in order to make sure your property will be compliant with applicable fire codes.

  • Native Or Suitable Plants City of Mccall
    Native or Suitable Plants City of McCall The following list of plants is presented to assist the developer, business owner, or homeowner in selecting plants for landscaping. The list is by no means complete, but is a recommended selection of plants which are either native or have been successfully introduced to our area. Successful landscaping, however, requires much more than just the selection of plants. Unless you have some experience, it is suggested than you employ the services of a trained or otherwise experienced landscaper, arborist, or forester. For best results it is recommended that careful consideration be made in purchasing the plants from the local nurseries (i.e. Cascade, McCall, and New Meadows). Plants brought in from the Treasure Valley may not survive our local weather conditions, microsites, and higher elevations. Timing can also be a serious consideration as the plants may have already broken dormancy and can be damaged by our late frosts. Appendix B SELECTED IDAHO NATIVE PLANTS SUITABLE FOR VALLEY COUNTY GROWING CONDITIONS Trees & Shrubs Acer circinatum (Vine Maple). Shrub or small tree 15-20' tall, Pacific Northwest native. Bright scarlet-orange fall foliage. Excellent ornamental. Alnus incana (Mountain Alder). A large shrub, useful for mid to high elevation riparian plantings. Good plant for stream bank shelter and stabilization. Nitrogen fixing root system. Alnus sinuata (Sitka Alder). A shrub, 6-1 5' tall. Grows well on moist slopes or stream banks. Excellent shrub for erosion control and riparian restoration. Nitrogen fixing root system. Amelanchier alnifolia (Serviceberry). One of the earlier shrubs to blossom out in the spring.

  • Reference Plant List
    APPENDIX J NATIVE & INVASIVE PLANT LIST The following tables capture the referenced plants, native and invasive species, found throughout this document. The Wildlife Action Plan Team elected to only use common names for plants to improve the readability, particular for the general reader. However, common names can create confusion for a variety of reasons. Common names can change from region-to-region; one common name can refer to more than one species; and common names have a way of changing over time. For example, there are two widespread species of greasewood in Nevada, and numerous species of sagebrush. In everyday conversation generic common names usually work well. But if you are considering management activities, landscape restoration or the habitat needs of a particular wildlife species, the need to differentiate between plant species and even subspecies suddenly takes on critical importance. This appendix provides the reader with a cross reference between the common plant names used in this document’s text, and the scientific names that link common names to the precise species to which writers referenced. With regards to invasive plants, all species listed under the Nevada Revised Statute 555 (NRS 555) as a “Noxious Weed” will be notated, within the larger table, as such. A noxious weed is a plant that has been designated by the state as a “species of plant which is, or is likely to be, detrimental or destructive and difficult to control or eradicate” (NRS 555.05). To assist the reader, we also included a separate table detailing the noxious weeds, category level (A, B, or C), and the typical habitats that these species invade.
