YIELD FROM EUCALYPTUS 



Information in regard to age of the grove and time of cutting obtained from Mr. 

 Bell, the former owner, and Mrs. Annette Thaxter, the present owner. 



YIELD. 



SUMMARY. 



Age, 13 to 20 years. Sprouts. 



Volume per acre, 4,964.8 cubic feet, which is equal to 55.2 standard cords, or 73.5 

 California cords. 



Volume per acre, 10,320 board feet* 



Volume of merchantable tops, including the trees too small to scale, per acre, 

 2,341.6 cubic feet, equal to 26.1 standard cords, or 34.7 California cords. 



YIELD FROM EUCALYPTUS OTHER THAN BLUE GUM. 



Although there are seventy-five or more different species of eucalyp- 

 tus growing in California, very few of them outside of blue gum are 

 found in grove form, the trees usually occurring either singly, in nar- 

 row belts, or in small patches. Old plantations of even an acre in 

 extent are extremely rare. It is, therefore, impossible to give the 

 yield from planted eucalyptus other than blue gum, except to make 

 the general statement that, although inferior to many of the eucalypts 

 in the quality of its wood and its durability in contact with the soil, 

 blue gum is by far the most rapid growing of the eucalypts. This 

 lack of definite data is very unfortunate in view of the extensive plant- 

 ing of the red, gray, and sugar gums that has taken place within the 

 last two or three years. The few eucalyptus groves more than five or 

 six years of age, outside of blue gum, which are now found in the 

 State show without exception slow growth and poor form and develop- 

 ment. The trees are either crooked and scrubby, or else spindling and 

 leaning, and few of the trees growing in grove form will make desir- 

 able timber. Whether this poor growth and form is a result of the 

 inability of the trees to grow in close stands, or whether it is due to 

 some other factor, it is impossible to state; but it may be of interest 



*The volume given in board feet is not in addition to the volume stated in cubic feet 

 and in cords, but is simply another way of expressing the same total.
