Hedgehogs (Erinaceus europaeus) are native to Great Britain but were introduced to the island of South Uist in 1974 and gradually colonised South Uist and Benbecula. In 1999 hedgehogs were confirmed in southern areas of North Uist. Hedgehogs eat the eggs and occasionally the chicks of waders, which breed at high densities in the Uists. Initial research by Royal Society for the Protection of Birds (RSPB) in 1998 suggested that predation by hedgehogs was having a significant effect on the wader populations in South Uist. In 2014, remote cameras were used on a sample of wader nests and found hedgehogs responsible for 52% of all predation in South Uist. The Uist Wader Project was set up in 2000 to remove hedgehogs from North Uist initially, but with a long-term aim to remove hedgehogs completely from the Uists. Various methods including lamping, trapping and the use of sni?er dogs were developed, trialled, and improved. We developed an Index of Abundance (IOA) of hedgehogs, using footprint monitoring tunnels. This IOA provides a means of confirming the impact of removal activities on the hedgehog population. In anticipation of scaling up, we carried out a removal trial on a two km² area at Drimore in South Uist. The trial demonstrated the e?ort required to reduce the abundance of hedgehogs from high density, 30 animals/km2, to zero and enabled the project team to estimate the resources required to eradicate hedgehogs from Benbecula, North and South Uist. The North Uist phase should be complete by the beginning of 2018, with only eight hedgehogs caught in 2016 and just one in 2017. Two years of monitoring are planned between 2018 and 2020, to confirm eradication.

Growinginterestintraditionalknowledge(TK),particularlyinrelationtothepredictionofweatherorclimate extremes, raises issues concerning the appropriate storage and management of the information collected. The Traditional Knowledge Database (TK Database) for the storage and use of TK associated with weather and climate prediction in the Paci c was designed with the following principles in mind: (1) preservation of the knowledge, maintaining cultural context wherever possible; (2) respect for intellectual property and cultural sensitivities around data sharing and use; (3) appropriate system design, accounting for ongoing costs of system maintenance and often intermittent Internet access; and (4) moving beyond data preservation to ensure continued use and growth of the TK. The TK Database was successfully deployed to four countries in the south Paci c and is regularly used by their national meteorological services, and partner organizations, both to preserve TK related to weather and climate and as a tool to assist in monitoring the TK indicators. As the rst database of its kind, the TK Database lls a critical gap in the appropriate storage and application of TK and provides an important foundation for future developments.
