CALIFORNIA 
Seed Collection Regions 
In order to permanently identify the regions from 
which MANINGSEED is collected, and thus enable cus- 
tomers to easily reorder the best tree seed for their 
needs, we use lot numbers to indicate region, zone, and 
elevation -- for example: 
Lot No. N3-0.5 (Orick) 
The first letter (N) indicates the region, and the first 
number (3) indicates the zone. The two numbers follow- 
ing (0.5) indicate the elevation in thousands of feet 
-- 0.5 = zero to 500 feet. 
Crescent 
City 
The predominate species growing on the east and west 
slopes of the Sierra Nevada Mountains in Northern Cal- 
ifornia are Ponderosa pine, Jeffrey pine and Sugar pine. 
Mixed with these pine species are Douglas fir, Red fir 
and White fir. 
Susanville 
On the coast there are impressive stands of Redwood -- 
Sequoia sempervirens -- the tallest living tree in Amer- 
ica. Mixed with the Redwood and occurring further east 
are large stands of Douglas fir. 
In the south, Region Fl, the King of the Conifers, the 
majestic Sequoia gigantea, grows in about 70 groves, 
totaling over 1000 big trees. These trees are native to 
the western slopes of the Sierra Nevada at elevations 
from 4500 to 8500 feet.
