GENERAL INFORMATION This plant list was created and approved by various agencies. Although the plant list was designed specifically for landscape fuel modification zones, the plant species identified in the list are also a good choice for ornamental vegetation for use around your home or business in other areas subject to the effects of wildfires (please refer to the requirements in OCFA Vegetation Management Technical Design Guideline C-05 if your project involves fuel modification zones). Photographs of these plants can be found by searching the internet. All plant species will still burn given sufficient heat and low moisture content. To get the best results for fire resistance, plants installed should be grouped and spaced in accordance with Attachment 6 from the OCFA Guideline C-05 titled, “Vegetation Management Technical Design Guideline”. To locate this guideline, go to www.ocfa.org and click the Ready, Set, Go! link. Fire resistance will also be increased through appropriate irrigation frequencies. The best plant forms to reduce the effects of wildfire are succulents such as Aloe, Agave, and Cactus. Additional plant forms that are good at reducing the effects of wildfire are Yucca species and low growing ground covers. For information regarding erosion control, contact a Geologist or other qualified professional. For questions regarding the list, contact OCFA at 714-573-6100. Before you purchase plants on this list you should verify with the nursery or plant provider that the specific species is suitable for your area and soil condition.

    Checklist of Ventura County Rare Plants (Twenty-second Edition) CNPS, Rare Plant Program David L. Magney Checklist of Ventura County Rare Plants1 By David L. Magney California Native Plant Society, Rare Plant Program, Locally Rare Project Updated 4 January 2017 Ventura County is located in southern California, USA, along the east edge of the Pacific Ocean. The coastal portion occurs along the south and southwestern quarter of the County. Ventura County is bounded by Santa Barbara County on the west, Kern County on the north, Los Angeles County on the east, and the Pacific Ocean generally on the south (Figure 1, General Location Map of Ventura County). Ventura County extends north to 34.9014ºN latitude at the northwest corner of the County. The County extends westward at Rincon Creek to 119.47991ºW longitude, and eastward to 118.63233ºW longitude at the west end of the San Fernando Valley just north of Chatsworth Reservoir. The mainland portion of the County reaches southward to 34.04567ºN latitude between Solromar and Sequit Point west of Malibu. When including Anacapa and San Nicolas Islands, the southernmost extent of the County occurs at 33.21ºN latitude and the westernmost extent at 119.58ºW longitude, on the south side and west sides of San Nicolas Island, respectively. Ventura County occupies 480,996 hectares [ha] (1,188,562 acres [ac]) or 4,810 square kilometers [sq. km] (1,857 sq. miles [mi]), which includes Anacapa and San Nicolas Islands. The mainland portion of the county is 474,852 ha (1,173,380 ac), or 4,748 sq.

    Drought-Tolerant and Native Plants for Goleta and Santa Barbara County’S Mediterranean Climate

    Drought-Tolerant and Native Plants for Goleta and Santa Barbara County’s Mediterranean Climate Drought tolerant plants for the Santa Barbara and Goleta area. In the 1500's California went through an 80 year drought. During the winter there were blizzards in Central California, the Salinas River froze solid where it flowed into the Monterey Bay. During the summer there was no humidity, no rain, and temperatures in the hundreds for many months. During one year in the 1840's there was no measurable rain in Santa Barbara. (The highest measured rainfall in an hour also was in Southern California, 11 inches in an hour) The same native plants that lived through that are still on the hillsides of California. California native plants that do not normally live in the creeks and ponds are very drought tolerant. The best way to find your plant is to check www.mynativeplants.com and do not water at all. But if you want a simple list of drought tolerant plants that can work for your garden here are some. Adenostoma fasciculatum, Chamise.

    1.26 Chaparral Nolina (Nolina Cismontana) – Category SL

    Volume 2D: Goals and Objectives for Species Focus Management Species 1.0 Plants 1.26 Chaparral Nolina (Nolina cismontana) – Category SL Management Units with Known Occurrences Chaparral nolina occurs in coastal sage scrub and open chaparral habitats in foothills from Ventura County south to San Diego County (Reiser 1994; Hess and Dice 1995; CNPS 2011). In the MSPA, the only known occurrence on Conserved Lands in the MSPA is in MU5 at Hellhole Canyon Preserve (see Occurrence Table or online map: http://arcg.is/2kFKRpZ); however, another occurrence was found in 2001 in MU4 on Conserved Lands in Cleveland National Forest (CNF), though its status is currently unknown (SANBIOS 2015). The occurrence on CNF lands burned in 2003 and 2007 and may no longer be extant. It was detected in 2005 following the 2003 fire; however, it was not observed during surveys in 2008 after the 2007 fire. Outside the MSPA, 3 occurrences were found on U.S. Forest Service lands at Viejas Mountain (CCH 2013; SDNHM 2013). Three more occurrences were found in MU8 on private, unconserved lands in the Pala area (SANBIOS 2013; SDNHM 2013). In 2015, 1 occurrence was found on military lands (CCH 2017; SDNHM 2017). Management Categorization Rationale Chaparral nolina should be managed as a Species Management Focus Category SL Species due to a high risk of loss from Conserved Lands in the MSPA and because managing chaparral and coastal sage scrub habitats alone will not ensure its persistence (see Vol. 1, Table 2-4). Chaparral nolina is at high risk of loss from the MSPA as there are only 1 to 2 recent occurrences on Conserved Lands.

Present address for NER: Dept of Ecology and Evolutionary Biology, Univ. of Toronto, Toronto, ON, M5S 3G5, Canada. 10 – C. D. Bertelsen, School of Natural Resources and the Environment, Univ. of Arizona, Tucson, AZ 85721, USA, and: Herbarium, Univ. of Arizona, Tucson, AZ 85721, USA. 65 Climate change-induced shifts in flowering phenology can expose plants to novel biotic and abiotic environments, 15 potentially leading to decreased temporal overlap with pollinators and exposure to conditions that negatively affect fruit and seed set. We explored the relationship between flowering phenology and reproductive output in the common shrub pointleaf manzanita Arctostaphylos pungens in a lower montane habitat in southeastern Arizona, USA. Contrary to the 70 pattern of progressively earlier flowering observed in many species, long-term records show that A. pungens flowering onset is shifting later and the flowering season is being compressed. This species can thus provide unusual insight into the 20 effects of altered phenology. To determine the consequences of among- and within-plant variation in flowering time, we documented individual flowering schedules and followed the fates of flowers on over 50 plants throughout two seasons (2012 and 2013).

  • Reference Plant List

    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.
