This paper discusses language planning measures in Guernsey, Channel Islands. The indigenous language is spoken fluently by only 2% of the population, and is at level 7 on Fishman's 8-point scale of endangerment. It has no official status and low social prestige, and language planning has little official support or funding. Political autonomy has not increased the language's status or stopped intergenerational transmission from declining. Most language planning initiatives are very small-scale and are undertaken by pressure groups or individuals, who focus on social prestige at grass-roots level rather than official status. The likelihood of success of current efforts is evaluated. (Contains 3 figures.)
