		FORM B1 – ROW AND TREE SELECTION HAZELNUT OBJECTIVE YIELD SURVEY 20xx					NATIONAL AGRICULTURAL STATISTICS SERVICE Oregon Hazelnut Marketing Board
BLOCK AND TREE MAP				Sample No.
1. Draw a sketch of the location of the orchard, including enough detail to locate the exact block. Indicate directions from the nearest town, roads to use, approximate mileage and any landmarks that might help if locating the block again.
N

2. Compute the approximate number of trees in the block by counting the number of trees along the length and width, then multiplying:
	Number of Trees:		x		=
		(length)		(width)		(height)
a. If the approximate number of trees is greater than 1,000, draw a sketch of the entire block and divide it into approximately equal sub-blocks of 500 to 1,000 trees. Be sure each sub-block has an accessible corner.
N

b. If you are NOT sub-blocking this orchard, skip to #3 below.

Number each sub-block in a serpentine manner and select a random number between 0.1 and the total number of

sub-blocks. Circle the number of the selected block. Indicate the starting corner.

N

3. Sketch the selected block on the grid below, one square equaling one tree space. Enter "b" for blank spaces and "o" for trees other than hazelnuts. Be sure to indicate the starting corner.
