Problems with the public
Traps were obviously interfered with, and the map shows where traps were sprung
Annual data analysis
As data accumulates, so the patterns of species distribution may be seen.
The stoats and weasels seem to be quite widespread across the altitudes.
Rats are everywhere. The most rats caught in one trap (9) was at a higher altitude, near Pouakai Hut.
