Lake Nganoke
9. Executive summary
This is a further updated report for Lake Nganoke for the year 2007/08. It is a
follow on report from the report prepared in 2006/07.
Predator control was carried out for only six months of the year. Other work
activities and the owners request not to service the equipment during the
months of May and June were the main reasons for this operation not receiving
the full 12 monthly maintenance rounds.
10. Recommendations
• Continue to carry on with integrated predator control at Lake Nganoke and
service the sites on a monthly basis or as time permits.
11. Objective
• To reduce predator populations to a level that improves and enhances the
management areas biodiversity values.
12. Operational area
The operational area remains unchanged and still covers the same six hectares
of Lake Nganoke and the adjacent Turanganui wetland.
12.1 Traps and bait stations
Fenn traps and Sentry bait stations continue to be used at Lake Nganoke, but
many were changed during the year as they had exceeded their use-by dates.
Prolonged submerged periods at times of high water had rusted some Fenns,
making then unsuitable for continued use. Bait stations were breaking down
due to over exposure to the suns ultra violet rays.
There are still 16 control sites in place around both wetland areas.
13. Operational results
Operational results are listed on a monthly basis as follows and are valid until
the end of June 2008.
