Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Callitris sulcata faces severe population decline primarily due to habitat fragmentation and clearing for agricultural development across its limited range in southeastern Australia. Mining activities and urban expansion have further reduced available habitat, while altered fire regimes disrupt the species' natural regeneration cycles. Climate change compounds these pressures through increased drought frequency and shifting precipitation patterns that affect seedling establishment.

Threat summary

Habitat

Callitris sulcata occurs in dry sclerophyll woodlands and open forests on sandy or rocky soils, typically on ridges and slopes in southeastern Australia. The species favors well-drained sites with low to moderate rainfall and is often associated with other drought-tolerant vegetation communities.

Frequently asked questions

Why is Callitris sulcata classified as Endangered?
Callitris sulcata is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Callitris sulcata faces severe population decline primarily due to habitat fragmentation and clearing for agricultural development across its limited range in southeastern Australia. Mining activities and urban expansion have further reduced available habitat, while altered fire regimes disrupt the species' natural regeneration cycles. Climate change compounds these pressures through increased drought frequency and shifting precipitation patterns that affect seedling establishment.
Where does Callitris sulcata live?
Callitris sulcata occurs in New Caledonia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Callitris sulcata?
The main threats to Callitris sulcata are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
