hmm...
yeah. 'fertilization' in the other meaning of the word from 'throwing fertilizer on a field'.
Might need to wait for fruit and flowers for that though.
In the meantime, why not generaste a free 1/X fertilizer in warm-seasons for one field in 10 tile range (with free path to hive).
Also untill flowering plants appear;
require # 'herbs' nearby a hive determines production of honey in a season (x/10).
wild hives can be harvested, but bees will be agressive no matter what precautions are taken.
wild hives can be collected with a beehive-basket, functioning similarly to animaltraps.
(I don't think they can be tamed, but maybe abstraction for settling them in the new nest?)
domesticated beehives are built from the captured bee queen.
-these can be harvested destructively (bees will die if they have no honey in winter)
-can also be 'cultivated'; only half the honey is taken.
-if the honey reaches 10/10, bees will start to produce queen bees, if left undisturbed for long enough(*) She will take 5 honey (representing half the population) and leave the hive to start a new one in a spot at least 15 tiles away from the maternal hive.
Free flying hives attack only if provoked.
new hive starts with 1 honey.
(*) maybe: have 10 honey at season start?
