The new bishop was not long in taking advantage of his Welsh origin to further the interests of his see in Mid Wales. The region between the Wye and the Severn had in times past been reckoned a part of Powys, and the death of bishop David of S. Davids in May 1176 seemed to provide an opportunity to recover it for the northern bishopric. He resolved to make a beginning with the border church of Kerry and engaged the assistance of the local authorities, both lay and clerical. But this was to ignore the recently appointed archdeacon of Brecknock, none other than the formidable Gerald. The two opponents met on the spot and a contest ensued, in which each excommunicated the other. According to the archdeacon, it was the bishop who had to make a crestfallen retreat; certain it is that in the long run, Kerry was retained by the see of S. Davids.
Adam does not appear otherwise in connection with his diocese. He was much in England, attended royal conferences in the spring of 1177, and was at the Lateran Council of 1179, where he defended his late master, Peter Lombard, against Walter of S. Victor. He d. at Osney abbey in 1181.
