APPENDIX 1:  TARGETED SURVEY

Objective: To locate extant populations of the Christmas Island Shrew.

Personnel:
The survey must be undertaken by a consultant with either previous field survey experience of Crocidurine shrews or extensive expertise using a wide range of survey techniques in targeted surveys for small mammal species within Australia. The consultant must have good lateral thought with the ability to use adaptive targeted survey strategies.

Duration:
To be conducted for one month sample periods in both the dry and wet seasons of each year for the five-year timeframe of the Recovery Plan or until extant populations have been located and the distribution fully assessed.

Approach:
Following from the survey of Meek (2000), a stratified survey across all primary plateau and terrace rainforest communities and in ecotones between these and other vegetation communities should be undertaken using a variety of additional or modified techniques.

Site Selection:
Sites should be selected in primary plateau and terrace rainforest at 2km2 intervals across the island. All sites need to be outside of crazy ant infestations or sites treated by aerial baiting in September 2002. Initially it is recommended survey effort be concentrated on the western section of the island (west of Margaret Beaches on the north coast and South Point on the south coast), with the following areas to be investigated as high priority:
 - 1985 shrew localities: plateau rainforest adjacent to the Shrine in LB4 and terrace rainforest at No 1 Dale.
 - plateau rainforest linking the two 1985 localities, including Ferguson, Murray, Bean and Camp Hill areas.
 - terrace rainforest between North West Point and Egeria Point.
 - terrace and plateau rainforest from Jones Point east to The Blowholes.
 - terrace and plateau rainforest along north coast from North West Point east to the eastern end of Margaret Beaches.

Logistically it is not feasible to obtain coverage of the entire island on each visit, both in terms of distances involved and the requirement to check traps frequently. Instead, it is recommended that a number of contiguous 2km2 areas be surveyed simultaneously.

For each 2km2 sector, the following land features be selected on different survey visits:
a. Coastal 2km2 areas:
 -  Ecotone of terrace rainforest and coastal vegetation or shoreline.
 -  Terrace rainforest on ecotone with inland cliffs and
