Mohi Bush

LOCATION | DATE LAUNCHED

Native bush of exceptionally high ecological value, spanning DOC-owned land and neighbouring private properties that also retain important remnants of native forest. The area has long been believed to support a colony of long-tailed bats, although no survey data currently exists to confirm this. This survey will directly test that long-held assumption and help establish whether long-tailed bats are present in the area.

Mohi Bush

Active – Phase 1

Objective/question

Determine bat presence/absence at the site, then progressively work through the 4-phase framework toward roost identification and habitat connectivity mapping (see Shared Methodology above).

Phase & trigger

Phase 1, in progress. Currently 18 of a planned 50 detectors deployed, rotating across sites — larger site than Rowe Bush. A 2-detector deployment summary (from Mohi + 1 neighbouring property) is available, but no data has been analysed yet from the current winter deployment.

Scale note

Larger in scale, time, and cost than Rowe Bush.

Deliverables & success criteria

Likely a Phase 1 findings report, same format as Rowe Bush. Success is simply undertaking the acoustic survey within the project area.

Activity Description/frequency
Detector deployment Currently 18 detectors deployed; plan to scale to 50, rotating across sites. A 2-detector deployment summary (from Mohi + 1 neighbouring property) is already available.
Field visits Install / service (SD swap) / retrieval — approx. monthly (same frequency as Rowe Bush)
Data processing The Bat Pack with manual verification, plus manual analysis to understand how bats are using the site and identify activity hotspots (same approach as Rowe Bush)
Analysis No data analysed yet from the current winter deployment
Reporting Summer/winter acoustic reporting schedule, same as Rowe Bush
Landowner/partner liaison Monthly, tied to the monthly detector check visit — likely as a short text or video update
Education & awareness Shared content, resources, and an annual report for the project

DOC Bat Recovery Plan – objective alignment

The 1995 DOC Bat (Peka Peka) Recovery Plan set five plan objectives (Section 8.0 of the plan, p.11). Mohi Bush aligns with objectives 1, 2, 4, 5.

Field Notes

A running diary from the field — updated whenever there's something worth logging from a site visit, detector check or survey.

Field Observations

Mid-winter detector check

Placeholder entry — replace with real notes. Visited both Mohi Bush detectors for a routine SD card swap; ground was very wet after last week's rain but both units were dry and recording. No obvious signs of disturbance around either site.


Neighbouring property added to survey

Placeholder entry — replace with real notes. Landowner next door agreed to host a third detector along the boundary tree line, extending coverage beyond the original Mohi Bush footprint. Unit installed and first data pull scheduled for next visit.


First detector deployed

Placeholder entry — replace with real notes. First acoustic detector installed at Mohi Bush, mounted on a mature tree at the edge of the grassland clearing. Marks the start of the Phase 1 presence/absence survey for the site.
