Seed Collection Regions 
South Bend The forests of Washington and Oregon are divided into 
. ‘L Pe E11 two major climatical regions by the Cascade Mountain 
Range. The Douglas Fir Region lies to the west of the 
mountains and the Ponderosa Pine Region lies to the 
east of the mountains. 
l. There are three specific climatic belts inthe Douglas 
Fir (green) forests of Washington and Oregon: 
(a) The so-called ''fog belt'' between the Coast Range and 
the sea on the Oregon and Washington coast, Regions 
1, 2, 3, and 4; 
(b) The interior valleys between the Coast Range and 
the middle elevation of the Cascades that extend from 
Puget Sound (Washington) south to the Siskiyou Moun- 
tains (Oregon), Regions 7, 8, and 9, and 
(c) Asmaller area inthe rain shadow of the Olympic Moun- 
tains(Washington) that includes a strip along the north- 
east end of the Olympic Peninsula, the eastern shore 
of Vancouver Island (British Columbia) and the Puget 
Tillamook 6 Sound Islands that lie to the east, Region 5. Region 6 
to the East is cooler and not as dry as Region 5. 
2. The Ponderosa Pine Region is a high plateau area 
with light rainfall and a wide annual variation of temper- 
ature. Ponderosa Pine is the major species, often 
Detroit occurring in mixture with White Fir, Larch, Lodgepole 
Pine, Sugar Pine and Douglas Fir (caesia). (This region 
is not divided into collection zones on this map). 
Valsetz oh In order to permanently identify the regions from which 
MANINGSEED is collected, and thus enable customers to 
Toledo easily reorder the best seed for their needs, we use lot num- 
Newport . bers to indicate region, zone, and elevation--for example: 
9 Lot No. 13-0.5 (Forks) 
Summi Cascadi The first number, (1), indicates the region, and the second 
Tidewate: ta number,(3), the zone. The two numbers following, (0.5), indi- 
cate the elevation in thousands of feet--0.5=zero to 500 feet.
