Yes, I consider a 10 the calmest, with 1 being the most loud/nippy (and reserved for those pesky Chinese
. Also, both males and females are chatty. Males sound the alarms more often, but females will get excited and start cheering on the boys when they rush to the defense. Remember, even though geese may be extremely quiet - that's extremely quiet for _geese_. Pilgrims, Sebastopols, Dewlap Toulouse, Giant Dewlap Africans, and American Buffs will still get excited and chatty, just nowhere near as bad as some of the other breeds.
Geese do fine with trees. They were traditionally kept in orchards to keep the weeds down and fatten up on windfallen fruit. They will chew on the bark of saplings, but they usually don't bother mature trees. From my experience, geese that eat bark are _extremely_ bored geese, or extremely hungry geese. Why would they eat bark if they have grass, weeds, and actual food? Bark, for most animals, is starvation-food.
If you have a heavily wooded area they would probably gnaw away at saplings and seedlings, which would help keep the area from becoming choked over.
