BOTANICAL AND ECOLOGICAL CHARACTERISTICS
SPECIES: Arctostaphylos glandulosa | Eastwood Manzanita
GENERAL BOTANICAL CHARACTERISTICS :
Eastwood manzanita is a long-lived, erect, spreading evergreen shrub.
It ranges from 5 to 8 feet (1.5-2.5 m) in height, with a lignotuber from
2 to 15 feet (0.6-2.5 m) in diameter. Root depth is from 8 to 28 inches
(20-70 cm). The leaves, stems, and fruits are glandular. The fruit is
a small drupe bearing hardcoated seeds [5,7,19,29].
RAUNKIAER LIFE FORM :
Phanerophyte
REGENERATION PROCESSES :
Sexual: Eastwood manzanita reproduces by seed [2,20,14]. Seeds are
dispersed by birds and mammals and can remain dormant for years [21].
Germination does not occur until after a fire, and is triggered by an
oligosaccharin leached from charred wood [20]. Seedling success rates
are low [14].
Vegetative: Eastwood manzanita sprouts from the lignotuber [7,14,18,19,20,44].
SITE CHARACTERISTICS :
Eastwood manzanita is found on dry, rocky, often steep slopes [16,29].
Soil: Eastwood manzanita grows in gravelly-clay soil. The soil layer
is typically less than 10 inches (25 cm) with a pH of 5.7 [10].
Elevation: Eastwood manzanita occurs between 1,000 to 6,000 feet
(305-1,829 m) [29].
Climate: Eastwood manzanita grows in a mediterranean climate, with cool
moist winters and hot dry summers [7,29].
SUCCESSIONAL STATUS :
Eastwood manzanita is shade-intolerant. It occurs in climax chaparral,
but is replaced by oak (Quercus spp.) woodland or coniferous forest in
the absence of fire [14,31,44].
SEASONAL DEVELOPMENT :
Eastwood manzanita flowers from February to April. The fruit ripens
from April to August, and seeds are disseminated from August to
November. Older leaves are dropped from August to February [2].
