Echoes Around Te Mata

HAWKE’S BAY | LAUNCHED 1ST OCTOBER 2025

Aside from the National Bat Survey, this is currently the largest citizen science project of its type in NZ, spanning 25 kilometres around Te Mata Peak and welcoming participants from school children to retirees and professional ecologists alike. It's deliberately open, designed to build a community around the work rather than gatekeep it. As a large-scale, citizen-science-led effort, the data it gathers feeds directly into more in-depth specialist projects, turning broad landscape coverage into targeted research. The overarching aim is to channel high-resolution local data into a national database, made possible by our automated data processing (otherwise known as “The Bat Pack”), and to show what's possible anywhere in the country (or the world) for anyone who wants to replicate what's been built here in Hawke's Bay.

Our approach:

Echoes is built around community engagement, with results shared with the Pekapeka Patrollers who take part. As each phase adds sites, this page will show where bats have been recorded and where they are yet to be found. We begin by Establishing which species are present, then Understanding where and when they're active. From there, we Build Capacity through shared knowledge and Monitor activity and change over time. These findings lay the groundwork for future specialist projects, from Identifying threats and establishing long-term monitoring sites to Cross-site comparisons and standardised reporting. Ultimately, this work will help us Act and Innovate, developing new survey techniques and guiding practical conservation efforts. This is the beginning of a longer story, revealing what's possible for bat conservation in the years ahead. This page follows the project as the work unfolds, sharing our objectives, field notes, maps and emerging insights. Right now, we're in Phase 1: Establish.

Activities
Activity Description/frequency

Data processing The Bat Pack, with manual verification.
Analysis Manual analysis to understand site use and identify hotspots.
Reporting Ongoing website content, plus a formal annual report after the season (e.g. August). Includes cross-site comparison where relevant.
Education & awareness Shared content and resources — weekly.

DOC Bat Recovery Plan – objective alignment

The 1995 DOC Bat (Pekapeka) Recovery Plan sets out five national objectives guiding bat conservation in Aotearoa. Mohi Bush directly contributes to four of these.

  • Research. Our ongoing survey and monitoring work builds the evidence base needed for effective bat management.
  • Status evaluation. Establishing presence, species, and distribution data contributes to national understanding.
  • Protection and monitoring. Long-term monitoring supports population tracking across the species' range.
  • Public awareness. Sharing this project's progress helps build public involvement in bat conservation.

The Plan's remaining objective concerns island-based short-tailed bat translocation, outside the scope of this mainland monitoring project.

Project objectives

Objectives 4–7 are greyed out as they don’t apply to citizen science projects like Echoes Around Te Mata.

#Objective
1Establish presence and species (via acoustic survey)
2Refine understanding of activity/distribution across the project area (ongoing survey — may reveal additional species)
3Identify hotspots (foraging/commuting/roosting) and seasonality of activity/distribution
4Identify threats and recommend conservation actions, based on findings from Objectives 1–3
5Establish a long-term monitoring site — track activity over time as a proxy for colony health and a wider indicator
6Trial and develop innovative conservation and survey techniques (e.g. roost boxes, refined methods)
7Cross-site comparison and standardised reporting, using a consistent graphical template — also an educational resource for other ecologists
8Raise awareness and build community engagement — social media, blog, video sharing the project journey (runs from Phase 1, continuously)
9Landowner and community relationship-building (runs from Phase 1, continuously)
10Capacity building and training, delivered online — matures once there's real project substance to teach from

Field Observations

The New Zealand National Bat Survey begins!

Are you going to participate this year?


Three citizen science legends kept surveying all winter

Three hardcore citizen scientists kept their detectors out right through winter — more than 150 survey nights and over 1,000 bat passes recorded (1,349 in total). These project participants are true heroes, and they’ve put us in a great position to kick off the ‘official bat survey season’ on 1 October 2026.
