Log

Logs are obtained by chopping down trees. You may also find a few scattered around the island.

They are needed for the construction of many buildings.

At 10,000 g each, logs are the heaviest item in the game, and hauling them to your camp can be tedious. It's a good idea to remove all non-essential items from your inventory before you go logging, so you can carry two at a time. (If you catch enough butterflies, you can carry even more.)
