Hello Laetitia!
That sounds like such an interesting trip and way of exploring the island!
I would encourage you to get in touch with
Teagasc, the Irish Agriculture and Food Development Authority as well as
Hedgerows Ireland, both of which may have interesting resources for you, as well as useful contacts, events or other opportunities. Hedgegrows Ireland, for example, offers ''Introduction to Hedge Laying''
demonstrations.
In addition, you might find these ideas (
here and
here) about sustainable activities of interest. Some farms also offer tours of their
peat bogs, something that your group might enjoy.
I hope that helps get you started!
Alex
