Crofting
Following the establishment of the first Crofting Commission in the 1880s, the whole of the island, together with the small adjoining Stack Island, was incorporated into the crofting townships:
The souming (a word originating in the Viking era) for each full share gives the right to put, on the common grazings (the high ground of Beinn Sgrithean and Beinn Stac), ten sheep, two cows and one Eriskay Pony (all plus their 'followers'—young up to one year old). Most crofts have one full share, but many have a half share, and a few have two shares, and one croft has as many as 3 shares.
The crofts are small (typically five hectares or less) and the land is rocky and exposed to harsh weather. These days, very few crofts are actively worked: there is little economic return in relation to the effort, and although there is a strong cultural attachment to the land, the demands and distractions of modern life leave little time for tending livestock and manual work. Much of the best grazing land, the machair of the north west of the island, has been compromised by house-building and the increasing opposition to the free-range grazing of cattle and sheep during the winter. Now, the most actively worked crofts are in the township of Bun a' Mhuillinn.
The island's common grazings, and the grazing of croft inbye land during the winter months, are regulated by the Eriskay Grazings Committee, the members of which serve a three-year term, supported by a Grazings Clerk, and according to the Grazings Regulations as provided for in the Crofting Acts.[23]
