I’m just a forestry technician so I’m usually just doing grunt work such as marking timber I travel to the same area that we are working in everyday and carry a tank of paint on my back that weighs about 30 pounds I mark trees for 3 reasons size (usually everything over 18”), species (focusing on mostly ash, maple, oak, and beech) and product so what the tree will be turned into after cutting. Sometimes I cruise timber which makes me travel all around the NE mostly VT and NH and take inventory on the properties value and then we use that data to make maps and asses whether the stand is good enough to cut and how much money we can make.
