Most foresters fresh out of forestry school begin their careers working for a public agency such as USFS or one of the state forestry agencies. Some work for forest industries. Those foresters working for state agencies will spend quite a bit of their time working with the public in public relations and promoting forest management on privately owned forest lands. Foresters working for the USFS or forest industries will probably spend more time actually in the woods. Rainy days are spent in the office with computers and secretaries analysing field data collected and preparing reports and timber management plans.
Some foresters also get involved in forest fire control or insect and disease surveys.
Don't get the idea that work in the woods means forest recreation like hiking, looking at wildlife, taking photos, etc. Timber cruising is physically strenuous because it is usually required that a compass line be followed through the woods and trees measured along that line. The terrain is sometimes nice and sometimes almost impossible in terms of swamps, cliffs, dense underbrush, heat, cold, insects, etc. It is usually enjoyable work though for them that like that kind of thing.
