Well our president is Niinistö as in "Lime(?) Bast Grove"
If I remember right, all plant fibre cordage on Ötzi was of lime bast
(Page 70 lists tree species useful for bast cordage):

https://books.google.fi/books?id=roEsBAAAQBAJ&lpgalso this was interesting:
"In the Mesolithic, cord has been recovered made from lime, elm, juniper, willow and rowan bast...
Historical records include the use of mosses, grasses, heather, lime, birch, hazel, beech, yew, pine and spruce...
The best bast is obtained from young trees cut in early summer,
though collecting it at this time implies a retting process lasting
several weeks, to degrade the soft tissues and separate the bast
from the outer bark. Bast can be processed more quickly in early
spring as the sap is rising, or in winter, in which case the bast can be
separated rapidly over a fire."
