Assessment Notes

Yet no info of ecology, status, trends or preliminary assessment.

Justification

Bondarzewia kirkii is associated with Nothofagus s.l. and appears to be present in most of the major forests that have retained a healthy population of mature trees. This is a wood inhabiting fungus so we have allowed 2 mature individuals for each functional individual. We do not think any new populations will be discovered but there may be additional sites yet to be found within the sub-populations and we have used a multiplier of x 10 to allow for yet to be identified sites. That produces a population of 30x2x10= 600 at 7 localities. That suggests that the population should be treated as vulnerable under B2 a & b and D1


Taxonomic notes

Bodarzewia kirkii J.A. Cooper, Jia J. Chen & B.K. Cui


Why suggested for a Global Red List Assessment?

Proposed by Pat Leonard. A large and easily identifiable orange polypore associated with the beech tree roots. Known from 30 records in numerous locations. Extent of Occurrence 338,340.820 km2 Area of Occupancy116.000 km2.


Geographic range


Population and Trends

There have been thirty records of Bondarzewia kirkii spread over both islands on New Zealand and it is present in most of the major concentrations of Nothofagus forest. There have been increasing records in the past 5 years, but these reflect increasing survey effort rather then an increasing population of the species.The greatly increased number of recorders using the I-naturalist app on this showy fungus is the main cause of the increase..

Population Trend: Stable


Habitat and Ecology

Bondarzewia kirkii is a parasitic fungus that fruits on the roots of Nothofagus s.l. trees throughout New Zealand. It appears to be long lived and to fruit on mature trees.


Threats

Nothofagus s.l. forests are almost all protected in New Zealand through designation as national park or scientific reserves. As such they are not under threat from land use change. Many of these forest have been logged in the past and the distribution and frequency of the fungus may be related to the age structure of the forest. The quality of many forest habitats is however deteriorating due to selective grazing by feral animals, notably deer and pigs. This has affected regeneration in some areas. Increasing periods of intensive drought, and wind-blow resulting from stronger winds seems to target older trees that form the would be hosts for this fungus.


Conservation Actions

Recognition of this fungus in the management plans for National Parks might help ensure its long term conservation.
