If you avoid exporting your iron tools, you can put off building an iron mine for a very long time and just live off surface iron to keep your tool supply healthy. If you have everything you need in the stockpile, workers will bring as much as they can carry to the job site, thus ensuring the building is finished in as few trips as possible. When materials are trickling in, workers might make lots of wasteful trips to the building site, carrying only 1 or 2 units of materials. When possible, don't build any structures unless you have all the materials needed for its construction already in stock. [Edit: Patch 1.02 says foresters will no longer cut down orchards) Building a forester lodge within range of an orchard will cause the foresters to cut the orchard's trees. Therefore, gatherers are the recommended source of food early on. One farm plot needs around 4 workers and produces up to 1k food per season. Farming is rather inefficient when compared to gathering. Any specialized workers who aren't currently working will do the same tasks as laborers. They will replace specialized workers that are lost. Once you've increased your population, keep a few laborers available in your town. Selling tools or leather clothing may be tempting, but firewood is far more plentiful. Firewood is remarkably valuable for trading, considering the amount that is needed for the town and what is produced. Once that's done, replace the forester with the other buildings, conserving space. Another method is to build a lodge and disable cutting, then to build up to maximum tree density. This results in a situation where it is actually more efficient to place herbalists and gatherers near forester's lodges than in young forests, which are less dense. Plants and herbs grow only under mature trees, and there is no such thing as an "ancient forest". As there seems to be no "ancient forest" restriction on herbalists, a forester will make a great combo with a gatherer, herbalist, and hunter. Both gatherers and herbalists need a forest to work in, and deer are often found in a forest.
Until you can afford cows or sheep( wool), hunters will be your only source of leather, which is needed for making most clothing.
They also help to keep people happy and healthy by producing 4 types of food.
Currently, gatherers are the best means of producing food, generating up to 3,000 food per season. Generally speaking, it is best to keep your houses close to where your citizens are working in order to keep their walking distances to a minimum. In addition, having a good source of food, as well as a forester, a woodcutter, and a blacksmith will help to ensure your survival. Depending on how many families you begin with (based on difficulty level) it is a very good idea to build a boarding house instead of individual homes before your first winter.
