Measuring & Mapping - The Early Days
This article and the Blog to which it is connected are being developed
It was in 1928 that:
"The nucleus of a new Forest Assessment Branch was formed by the employment of three specially trained European foresters from Norway - Bjarne Dahl, Kristian Drangsholt and Bernard Johannessen."
"Early work starting in the Rubicon and Royston forests consisted initially of a baseline survey followed by transects 5 chain apart using tape, chain, compass. Abney level, and Aneroid barometer with 1 chain wide strips in which plots were measured to record species, height, diameter and condition of trees to calculate volume of timber. This early work by these Norwegian foresters initially being based at places like Taggerty and Marysville eventually extended across most of the foothill forests of the State with transects or strips then being placed further apart at 20 chain intervals giving a 5% sample of the assessment block."
"These strip assessments continued across the State, with forest mapping and classification carried out using interpretation of aerial photography undertaken by the RAAF. Assessments were generally in remote locations with access by 4WD tracks, with staff based in temporary camps under canvas tents. Some assessment teams were also based in rented houses and also huts in road construction camps."
"And later on, assessment teams comprising 2 to 3 foresters and 3 to 4 chainmen camped in the mountain forests often in grassy clearings in high elevation snow gum woodland. And at other times assessment teams were camped in caravans in more accessible parts of the forests."
All the above quotes come from Roger Smith.
Assessments of this type continued into the 1960s.
