Thanks for your answers. It looks like it is pretty clear what is the currently accepted tag for orchards then. As for the difference between orchard and farmland - ignoring plantation for its missing documentation and very rare use -, we identified the following key differences between orchard and farmland which should be very clear:
- In an orchard, plants are cultivated which are perennial, the plants have continuance. Usually only the fruit of the plants are picked. From satellite imagery, orchards usually appear as systematically planted bushes/trees or rows of hedges separated by corridors (for machines/workers) - Farmland grows plants that are harvested as a whole (i.e. with tractors), thus the actual crop can change during the years and even several times within a year (see crop rotation) as after the harvest, nothing is left from the plant. On satellite imagery, they usually appear as an acre, meadow (when fallow) or densely planted high grass/cereals. Apart from that, I generally agree with those that answered that they would prefer "produce" - for the same reasons. Especially for things like oil_palms, banana_plants, coffee_plants, vanilla_plants, the various types of berries etc. the "trees" key does not really fit. Moving forward, would anyone think that "produce" is definitely the wrong key to use for detailing on the produce/crop/type of orchards? (I am not rallying to make the other two keys deprecated here, this is just about which of the three keys the app should use to add a tag.) Greetings Tobias P.S: Here is a list of different types of produce (of orchards aka plantations) we identified.
