Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2022-2023 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes replaces all previous NZTCS lists for vascular plants. Previous assessments can be found here.

Similar taxa
Lachnagrostis billardierei subsp. tenuiseta is a common eastern Australian coastal grass that has been recognised from New Zealand based on three gatherings examined from only one New Zealand Herbarium (Austin 2012). Therefore this subspecies is potentially more widespread as it is very easily confused with L. billardierei subsp. billardierei.
Distribution
Indigenous. New Zealand: North Island (Northland and Auckland).
Habitat
In New Zealand this grass has been gathered from coastal cliff faces and sandy beaches and associated dune systems. However, as it is only recently recognised for New Zealand (Brown 2012) its exact habitat preferences remain to be ascertained.
Threats
Lachnagrostis billardierei subsp. tenuiseta is listed as “Data Deficient” qualified SO [Secure Overseas] and threats to it in New Zealand are poorly understood.

Etymology
lachnagrostis: From “lachne” (wool) referring to the distinctive callus hairs of this genus and “agrostis” by which Trinius (1820) actually meant “a grass” (not an Agrostis). So the generic name means “a hairy (woolly) grass” not “a hairy (woolly) Agrostis” as is often incorrectly stated (see Gardner 2014).
billardierei: Named after Jacques Houttou de Labillardiere (1755-1834), 19th century French botanist who described several New Zealand plants
