AbstractPrecise and accurate plant weight data are important to range managers, but difficult and expensive to obtain. Indirect and nondestructive estimates are especially desirable where vegetation is sparse and slow-growing on permanent plots. A new indirect, nondestructive approach developed in Australia, the reference unit method, was quantitatively related to clipped weights of winterfat (Ceratoides lanata) browse in Curlew Valley, Utah. The reference unit method was quite precise, accurate, and efficient in predicting browse weights even though size and form of the shrubs differed greatly. The only major disadvantage was mental fatigue created by the requirement of greater sustained concentration.
