Assessment Notes

Justification

Vulnerable: A2. B2ab(iii). Based on an inferred population reduction over the next 20; small geographic range B2 AOO 24 km2; quality of habitat decline (iii) due to tourism pressures and disease management (Waitakare site).


Taxonomic notes

The ectomycorrhizal genus Amanita well studied in New Zealand, with relatively few, and well recorded species. Amanita mumura is a distinctive uncommon endemic species associated with Nothofagaceae and Myrtaceae


Why suggested for a Global Red List Assessment?

Distinct species known from 4 locations and 7 records in North Island of New Zealand and under pressure from land-use change.


Geographic range


Population and Trends

Population Trend:


Habitat and Ecology

The species is ectomycorrhizal with Southern Beech (Nothofagaceaea) and with Tea-Tree (Myrtaceae).

Temperate Forest

Threats

Populations in three of the sites (Waitakare, Tongariro, Tararua) are adjacent to popular walking tracks subject to increasing tourism with consequent impact on the immediate areas. The population at the Waitakare site is likely to decrease over the next 20 years as the impact of Kauri die-back on the dominant Kauri forest alters the forest structure. Areas are also likely to be disturbed as a consequence of disease management actions.

Research needed
