FOREST TREES ON THE POLLARD ESTATE AT NE- 

 HAWKA, NEBRASKA. 



By R. T. Guthrie. 



For the purpose of aiding in the collection of definite in- 

 formation on native and exotic trees in Nebraska, a list was re- 

 cently made of trees growing on the Pollard estate at Nehawka. 

 A similar study was made last year on the Morton estate at 

 Nebraska City, the results of which were published in Volume 

 II of the Forest Club Annual. 



Nehawka is only fourteen miles distant from Nebraska 

 City and seven miles from the Missouri River; the soil and 

 climatic conditions are practically the same in both places. All 

 the trees on the estate have been planted within the last forty 

 years by Mr. Pollard, who has been greatly interested in finding 

 trees suited to local conditions. Most of the trees studied were 

 growing on and near the top of a low hill where the majority 

 grow in the open and are branched low or quite to the ground. 

 In only one instance were the trees planted close enough to- 

 gether to kill the lower branches. This was in a shelterbelt 

 about 400 feet long of Austrian Pine (Pinus austriaca L.) com- 

 posed of three rows planted six feet apart. The trees averaged 

 from 34 to 38 feet in height and 8 to 14 inches in diameter at 

 breast height. The trees on the outer sides of the belt were 

 branched to the ground but the branches of the inner row, though 

 persistent, were killed about three-fourths to five-sixths of the 

 height of the trees. No weeds or grass occurred and the forest 

 floor was covered with needles. 



Of the 49 tree species and varieties in the following list 

 seven are foreign and the rest are native to the United States. 



Abies concolor (Gord.) Parry. White Fir. Height 10 feet, 

 diameter 2 inches. Branched to the ground, excluding grass. 

 Pyramidal crown. 



Acer ncgnndo L. Box Elder. Height 28 feet, diameter 7 inch- 

 es, clear length 5 feet. 



Acer saccharimtm L. Silver Maple. Height 45 to 48 feet, in 

 a small open grassy park, diameter 4 to 10 inches, clear 

 length 20 feet. Older trees, standing alone were 24 inches 

 in diameter. 



Acer sacch annum wierii (Pax.) Sudw. Cutleaf Silver Maple. 

 Height 12 feet, diameter 2 inches. Hybrid, propagated by 

 cuttings.
