Estimates for vegetation types are that 49 percent of the area is conifer, 45 percent is hardwood, and 6 percent is brush or open. See figure 25. Cost EstimatesâThe sum of the approximate straight line distance between sample stands as measured from the map is 104,000 feet. Thus: Field costs Aerial photos Mapping $2,243 490 1,147 Total costs $3,880, or $0,254 per acre. L E(MS) D F 104,000/10,560 = hours.

DiscussionâThis technique is seldom used in forest inventories. When polygons or stands are mapped, useful correlated attributes are also noted. Attributes such as vegetation type, density, and height may then be used to Forest Boundary N 1 i i i â 1 0 FEET 5000 a.
