NEWS LETTER 
BULLETIN NO. 2 
DOUGLAS FIR SEED SOURCES lx Apps - 
The parentage of tree seed greatly influences the 
quality and rate of growth of all planted forests. Because 
of this fact, MANNING SEED COMPANY has enlarged its collection 
area to supply seed from high quality trees in a variety of 
situations in order to better meet the requirements of our 
customers. 
To insure the integrity of every seed source, our 
seed has been collected and carefully processed under the di- 
rect supervision of technically trained foresters. Each lot 
of seed is positively identified with the area from which it 
was collected so that we can duplicate future collections at 
your request. 
We suggest that you follow two principles of sound 
management in purchasing seed for reforesting your land: 
1. Play safe by using seed from a climatic environ- 
ment similar to the area to be reforested. 
2. Experiment with seed from other environments in 
an attempt to introduce better trees of faster 
growth. 
, We collect seed from all locations in the Pacific 
Northwest some of which are listed on the attached sheet. 
Hach locality is coded by a system that is based on seed zones 
as designated by Manning Seed Company with weather data as 
compiled by Leo A. Isaac of the Pacific Northwest Forest and 
Range Experiment Station and published in his bulletin "Better 
Douglas-fir Forests from Better Seed".
