Abstract: | The archaeological site of Lavazzé at 2108 m a.s.l., and the summer farming site of Borghetto Sotto at 1897 m a.s.l., have
been studied using pollen analysis. The pollen diagrams reflect human disturbance from the Bronze and Neolithic ages respectively.
The name Lavazzé is also used as a local name for Rumex alpinus. At both sites, significant values of R. alpinus, up to about 10% of total terrestrial pollen, have been recorded, from about 2400 b.p. (ca 360 cal b.c.) onwards, although Lavazzé is above the present-day known local limit for R. alpinus. Written sources document local growth and cultivation of the species at 1300 m. It was used for various purposes in the
past, and the high values are interpreted as reflecting former intensive local growth. Local cultivation at higher altitudes
should not be excluded. Use of R. alpinus is known as far north as Scotland and Finland, and the species ought to be regarded as an apophyte and/or a naturalised crop. |
