For example, workers picking berries may be legal only with the landowner's permission. There are some significant differences in the rules of different countries. In Denmark, there is a more restricted freedom to roam on privately held land. All dunes and beaches and all publicly owned forests are open to roaming. Uncultivated, unfenced areas are open to daytime roaming irrespective of ownership status. Privately owned forest have access by roads and tracks only. In Finland, the freedom to roam and related rights are called """" in Finnish and """" in Swedish (lit. "the everyman's right"), similar to other Nordic countries. Everyone may walk, ski, ride a horse or cycle freely in the countryside where this does not harm the natural environment or the landowner, except in gardens or in the immediate vicinity of people's homes (yards). Fields and plantations, which may easily be harmed, may usually not be crossed except in the winter. It is also possible to establish outdoor recreation routes on private land, based on an agreement on the rights of use or by official proceedings in accordance with the Outdoor Recreation Act, for example. One may stay or set up camp temporarily in the countryside, a reasonable distance from homes, pick mineral samples, wild berries, mushrooms and flowers (as long as they are not protected species). One may fish with a rod and line (only still waters), row, sail or use a motorboat on waterways (with certain restrictions), and swim or bathe in both inland waters and the sea. One can walk, ski and ice fish on frozen lakes, rivers and the sea. Income from selling picked berries or mushrooms is tax-free. Picking cloudberry may be temporarily restricted to local residents in parts of Lapland. In the autonomous province of Åland the right to camp's inclusion in the right to roam was disputed, but since 2013 this is no longer the case. One may not disturb others or damage property, disturb breeding birds (or their nests or young), or disturb reindeer or game animals. One may not cut down or damage living trees, or collect wood, moss or lichen on other people's property, nor may one light open fires without the landowner's permission (except in an emergency). It is acceptable, however, to use an alcohol burner, wood stove or similar device that has no hot parts touching the ground. One may not disturb the privacy of people's homes by camping too near to them or making too much noise, nor litter, drive motor vehicles off-road without the landowner's permission, or fish (excluding angling) or hunt without the relevant permits.
