was conducted (see Objective 2 in section 3.1.1), with the aim of increasing numbers in existing populations as well as establishing them in additional locations.
    * Nursery-grown plants were provided to the Department of Infrastructure, Transport, Regional Development, Communications and the Arts (DITRDCA), the Norfolk Island Regional Council (NIRC) and the Norfolk Island community to enable vegetation restoration across the island, with over 2000 plants disseminated for community plantings.
    * Some plant species endemic to Phillip Island were established on Norfolk Island.

Management actions—fauna

    * Around 70 protected nests for Norfolk Island green parrots were maintained in the national park.
    * A network of nest boxes for the Norfolk Island morepork was also maintained in the national park, with boxes raised to higher, more suitable positions and new boxes added following a review in 2019. A smaller number of boxes were also placed in public reserves.
    * On Phillip Island, nesting shelters were installed for white-necked petrels and Kermadec petrels, with a high level of use by breeding pairs of the two species.
    * An attempt was made to translocate Norfolk Island green parrot chicks from Norfolk Island to Phillip Island in 2017; though it was unsuccessful, much was learned to inform potential future attempts to establish an insurance population of the species.
    * A captive breeding program for Campbell's keeled glass-snail and Suter's striped glass-snail was initiated, with the aim of breeding snails at Taronga Zoo (NSW) and establishing new populations with captive-bred founders in a fenced and managed area on the island.

Monitoring undertaken

Surveys of many threatened species were undertaken during the life of the plan, either by continuing existing monitoring programs or through establishing new programs (particularly in the later years). However, there were some gaps—for example, no reptile surveys were undertaken.

Molluscs
    * The Australian Museum conducted surveys within the national park for Campbell's keeled glass-snail in 2020 (Hyman & Köhler 2020) and for Gray's glass-snail in 2023, with systematic monitoring of the Campbell's keeled glass-snail population occurring every three months since November 2021. There was also periodic monitoring of the population of Suter's striped glass-snail by NIRC.

Reptiles
    * Reptiles were not surveyed during the life of the plan.

Birds
    * Targeted ongoing monitoring of Norfolk Island green parrot nests was undertaken monthly during the breeding season. Annual surveys of the population were conducted by researchers from Massey University between 2013 and 2018 (Skirrow 2018). A research project from 2021 provided further information about the population, including on use of protected nests (Gautschi et al. 2022).
    * Island-wide surveys of the Norfolk Island morepork were undertaken in 2019–2020 as part of a PhD project. Monthly nest box monitoring in the national park occurred during
