Abstract:
Tree diameter breast height (dbh) was measured on 879 permanently marked trees by two experienced professional foresters. Error rates were approximately equal between observers. Measurement error rates of 5% of tree diameter or greater may be expected in dbh measurements on as many as 5% of measured trees. West. J. Appl.
