For some years efforts have been made by certain societies in the British Isles to preserve the flora of those islands from devastation at the hands of persons who collect flowers and plants either for their own pleasure or for sale. Recently the scope of this protective campaign has been enlarged to take account of injuries done tc plants from natural or indirect artificial causes. Mr A. R. Harwood has called attention to the far-reaching importance of these effects. Thus periow 'A drought cause the extermination of many plants, montane and ericetal species being especially susceptible. Bog-pools are liable to be completely dried up, with partial destruction of their flora. Drainage seriously disturbs the natural vegetation of a country. Thus the typical flora of the Fens is disappearing. Peat-cutting in Ireland has similar effects. Deforestation works striding changes in the flora. Goll links have been detrimental to certain species of limited distribution. Mr Harwood urges that wherever these and other similar causes are at work efforts •should be made to obtain, in the case of an association of plants, a reservation, and in that of a single station for a rare plant some adegua'.e means of protection.
