The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.

Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley.

Small bushy tree bearing glossy green thin undulating oval leaves and dark purple fruit inhabiting the upper North Island. Leaves 5-12.5cm long by 3-5cm wide, taper to both the tip and base, leaf stalk dark. Flowers yellowish, in clusters. Fruit 15-20mm long.
Endemic. Three Kings and North Islands. Common to about Mokau in the west and the Rotorua lakes area and Mahia Peninsula in the east
Coastal lowland and lower montane forest. Mangeao is usually a fairly localised tree over much of its range but in the Waikato and Bay of Plenty, particularly on the deep so called “ash” soils and on the limestones in the western Waikato it can be the dominant canopy tree. Although mangaeo seems to like high rainfall it is (or was) also an important tree on the lava fields of Auckland, and it is one of the few tree species to grow on the ultramafic rocks of North Cape.
Stout, spreading tree up to 18 m tall; trunk up to 0.80 m dbh; usually solitary, rarely branched from base, often sporting numerous suckers and epicormic growth; bark dark grey to grey-brown, firm (not flaking). Branches stout, initially upright and then shortly to widely spreading, branchlets numerous, sparingly lenticillate, glabrous. Leaves alternate, subcoriaceous, glabrous, adaxially glossy dark green, yellow-green or green suffused with red, sometimes mottled or spotted with dark red or purple (emergent leaves often glaucescent or deeply tinged wine-red), abaxially glaucous or tinged wine-red; midrib raised on both surfaces, veination distinct when fresh or dried; petioles 15-30 mm long, somewhat wiry, dark green red or maroon-black; lamina 50-130 × 30-60 mm, ovate, oval, ovate-elliptic, apex obtuse to subacute, base broadly cuneate. Inflorescence an axillary, racemosely arranged, 4-5-flowered, open or rather congested, involucrate, umbel; peduncle 10-40 mm long, rigidly wiry, pedicels sparsely, minutely, pubescent. Involucrum comprising 4, 5-10 mm long, broadly oblong to oblong-elliptic, glabrous, somewhat fleshy, ± caducous pale green, cream (often red-tinged) scales. Flower perianth segments 4-6(-8), 4-5 mm long, cream, white, pale yellow or greenish,oblong to ovate. Stamens 10-12(-18); filaments slender, 0.8-2.6 mm long, white or pinkish white, biglandular; staminodes flattened, biglandular; stigma dilated,irregularly 3-lobed. Drupe 15-22 mm long, 1-seeded, subovoid to ovoid, seated in enlarged perianth tube; mesocarp purple-black. Endocarp membranous, 10-13 mm long, dark brown.

Although easily grown from seed mangeao is often fickle and hard to maintain. In nursery conditions seedlings and saplings can be difficult to maintain. Even apparently well established trees will in cultivation inexplicably die. It for this reason that mangaeo is rarely available from nurseries.
Not Threatened. Mangaeo while certainly not threatened at a national level is experiencing a decline over some parts of its range. While possum browse is a factor in some areas, die back of apparently healthy trees in areas where possums are controlled or scarce is of some concern. From time to time “mangaeo die back” is reported in the media - the cause of this “die back” warrants further study.
