Overstory associates not listed in Distribution and Occurrence are foxtail pine (Pinus balfouriana), shore pine (P. contorta var. contorta), Washoe pine (P. washoensis), Brewer spruce (Picea breweriana), golden chinquapin (Chrysolepis chrysophylla), tanoak (Lithocarpus densiflora), and California bay (Umbellularia californica) [19,32,34]. Understory shrub associates include greenleaf manzanita (Arctostaphylos patula), bearberry (A. uva-ursi), antelope bitterbrush (Purshia tridentata), Fremont silktassel (Garrya fremontii), huckleberry oak (Quercus vaccinifolia), snowbrush (Ceanothus velutinous), squaw carpet (C. prostraus), mountain big sagebrush (Artemesia tridentata var. vaseyana), Oregon-grape (Mahonia nervosa), blue huckleberry (Vaccinium membranaceum), and prince's pine (Chimaphila umbellata) [5,14,24,32,37]. Herbaceous associates are long-stolon sedge (Carex pensylvanica), California fescue (Festuca californica), Lemmon needlegrass (Stipa lemmoni), Hall bentgrass (Agrostis hallii), Rocky Mountain gentian (Gentiana affinis), purple mountain parsley (Oreonana purpurascens), spreading phlox (Phlox diffusa), and Brewer lupine (Lupinus breweri) [15,26]. Publications naming pinemat manzanita as a dominant component of forest understories are as follows: Preliminary plant associations of the southern Oregon Cascade Mountain Province [2] Terrestrial natural communities of California [13] Plant associations of south Chiloquin and Klamath Ranger Districts--Winema National Forests [14] Montane and subalpine vegetation of the Klamath Mountains [32] Plant associations of the central Oregon Pumice Zone [37]


SPECIES: Arctostaphylos nevadensis
IMPORTANCE TO LIVESTOCK AND WILDLIFE : Black bear, black-tailed deer, coyote, and various birds and rodents eat pinemat manzanita fruits [12,31]. Black-tailed deer browse seedlings for the first 3 years following fire. Foliage of older plants is rarely consumed by wildlife or livestock [31]. PALATABILITY : Mature pinemat manzanita browse is unpalatable to all classes of livestock and wildlife [31]. NUTRITIONAL VALUE : NO-ENTRY COVER VALUE : NO-ENTRY VALUE FOR REHABILITATION OF DISTURBED SITES : Pinemat manzanita is recommended for stabilizing soils on steep slopes [2,10]. Plants are started from stem cuttings. Containerized pinemat manzanita planted to prevent erosion of soil into Lake Tahoe, California showed 63 percent survival after 12 years when planted in spring. Survival of fall-planted pinemat manzanita was 23 percent at year 12 [33]. If soil excavations are shallow, pinemat manzanita recovers rapidly from log skidding damage via adventitious rooting and stem growth [9]. OTHER USES AND VALUES : Pinemat manzanita is used for ornamental landscaping [11]. OTHER MANAGEMENT CONSIDERATIONS : NO-ENTRY


SPECIES: Arctostaphylos nevadensis
GENERAL BOTANICAL CHARACTERISTICS : Pinemat manzanita is a native, spreading to prostrate, evergreen sclerophyllous shrub from 1 to 2 feet (0.3-0.6 m) in height. It is much-branched, with branchlets becoming viscid with age. It typically lacks a lignotuber (see Taxonomy). The bark is thin and freely exfoliating. A description of its root system was not found in the literature. The fruit is a berrylike drupe containing several nutlets [6,17,21,25]. RAUNKIAER LIFE FORM : Phanerophyte REGENERATION PROCESSES : Vegetative: Pinemat manzanita roots adventitiously where stems contact soil [3]. Plants buried under tephra following the 1980 eruption of Mount St. Helens produced 5 to 10 adventitious roots per centimeter of stem during the next growing season [1]. Manzanita species such as pinemat manzanita that lack a lignotuber generally do not sprout after aboveground portions of the plant are damaged [3,25]. Sexual: Little is known about pinemat manzanita sexual regeneration except that it establishes from soil-stored seed in large numbers following fire [27]. Seedling recruitment at other times is not documented in the literature. Manzanita species seeds are disseminated by frugivorous birds and mammals [31]. SITE CHARACTERISTICS : Pinemat manzanita is an indicator of cold, dry sites [23]. It occurs in a modified maritime climate: winters are wet, but high pressure systems in summer result in clear, dry weather [24]. Precipitation may be rain or snow, depending upon elevation. Pinemat manzanita occurs from 2,000 to 10,000 feet (610-3,049 m) in elevation, and is most common above 5,000 feet (1,524 m) [25]. The typical growing season is therefore short; snowpack often does not melt until July [2,24]. Soils supporting pinemat manzanita are typically shallow, infertile, and poorly developed [2]. Textures vary from sand to loam and often contain coarse fragments [26,30,37]. Pinemat manzanita tolerates serpentine soils but is not restricted to them [16,39]. SUCCESSIONAL STATUS : Facultative Seral Species Pinemat manzanita colonizes disturbed sites [17]. It grows well in open plant communities where light levels are high, and persists until late seres. It does not tolerate the low light levels of closed canopy forests. McNeil and Zobel [22] reported that pinemat manzanita in the understory of a white fir (Abies concolor) forest of Crater Lake National Park, Oregon, died where the canopy had closed. SEASONAL DEVELOPMENT : Pinemat manzanita phenological development in the Cascade Range of central Oregon is as follows [29]: growth begins: late May flowering: late May to mid-June fruit develops: mid-June to early July fruit sets: mid-July to late September


SPECIES: Arctostaphylos nevadensis
FIRE ECOLOGY OR ADAPTATIONS : Pinemat manzanita establishes from seed following fire [17,27]. POSTFIRE REGENERATION STRATEGY : Shrub without adventitious-bud root crown Ground residual colonizer (on-site, initial community)


SPECIES: Arctostaphylos nevadensis
IMMEDIATE FIRE EFFECT ON PLANT : Fire kills pinemat manzanita [17]. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : Pinemat manzanita establishes from seed during the first postfire growing season [17]. It may be an obligate seeder, requiring fire and/or charred wood lechate to break seed dormancy. The seed, however, has not been tested under laboratory or other conditions for such fire-stimulated germination responses. Data on postfire density, frequency, or growth rates of pinemat manzanita seedlings are not available. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : NO-ENTRY
