Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/154603516/154603875

Justification

Pluteus bressollensis is an easily identified and visible New Caledonia endemic. It is known only from two records, both from moist, semi-montane forests, in the south-west central part of the country. The type locality is Mt Mou (published in 2009), the other collection is from Moindou (collected in 2014). The habitat is largely unmanaged and undergoing change due to feral animals and is highly susceptible to fire as 1.5% of the country burns annually. 

The total area of available habitat is small and within a restricted range, giving the species a calculated EOO of 480 km2. There are three relatively small patches of suitable habitat with in this area, each susceptible to fire. These three patches are treated as separate locations as they are small enough to be consumed by a a single fire event. 

Given the small area of suitable habitat and threat of fire the species is assessed as EN B1ab(i,ii,iii,v)+2ab(i,ii,iii,v).

Geographic range

This is an easily identified and visible New Caledonia endemic. It is known only from two records, both from moist, semi-montane forests, in the south-west central part of the country. The type locality is Mt Mou (published in 2009), the other collection is from Moindou (collected in 2014). Suitable habitat for the species is restricted to three, relatively small patches of forest in the south-west central part of the country.

Population and Trends

It is known only from two records, both from moist, semi-montane forests, in the south-west central part of the country. The type locality is Mt Mou (published in 2009), the other collection is from Moindou (collected in 2014). Suitable habitat for the species is restricted to three, relatively small patches of forest in the south-west central part of the country. The habitat is largely unmanaged and undergoing change due to feral animals and fire.

Population Trend: decreasing


Habitat and Ecology

Pluteus bressollensis is a distinctive species, easy to identify in the field. Distribution is limited to wet montane forests.

Threats

Only a very small portion of the original forest cover of New Caledonia remains. Clearing in the past for timber and to create grazing and agricultural land have destroyed much of the forest cover. Wild fires and open cast mining have also accounted for extensive losses. What remains is now partially protected by Botanical Reserves of which Mont Mou is one. There is however virtually no active management to encourage regeneration or to discourage invasive species.

Pigs are the main pest species at Mont Mou and Katricoin and probably specifically target fungal species. Fire is prevalent throughout the country, with approximately 1.5% of the country burning each year.

Conservation Actions

Recognition of the role of fungi in the ecology of forests by including references in management plans would be helpful. More effective control of feral animals would be beneficial.

Research on the effects of feral animals on vegetation is ongoing but needs to be extended to cover fungal populations.

Use and Trade

The species is not utilized.
