Scientific name: Grevillea iaspicula

Conservation status in NSW: Critically Endangered

Commonwealth status: Endangered

Gazetted date: 11 Dec 2009

Profile last updated: 06 Apr 2023

Description

The Wee Jasper Grevillea is an erect shrub growing to 2.5 m tall. It has light green, pointed leaves to 35 mm long and 10 mm wide. The small flowers hang in spider-like clusters. The tube is cream coloured, the long style is deep pink. The tube is smooth outside and hairy inside. Flowers are followed by papery-woody capsules.

Distribution

The Wee Jasper Grevillea is found only in the Wee Jasper area and on the shores of Lake Burrinjuck near Burrinjuck village on the border of the Southern Tablelands and South Western Slopes. Although there is no evidence that the Grevillea was widespread in the recent past, it is possible that some of its original population was submerged following the damming of Lake Burrinjuck.

Habitat and ecology

Grows on rocky limestone outcrops and around sink holes and cave entrances.
Vegetation is open woodland dominated by White Box (Eucalyptus albens) and Apple Box (E. bridgesiana) trees
Often occurs as a co-dominant species within the shrubby understorey of its open woodland habitat.
Flowering is mostly in winter and spring..
This species is primarily bird-pollinated (as will other red or pink-flowered grevilleas).
The species readily sets seeds and these ripen in late December.
Recruitment is episodic and dependent on favourable seasonal conditions, but in favourable conditions and where stock grazing is excluded seedling establishment can be reasonably plentiful.

Threats

Loss and degradation of habitat and/or populations by invasion of weeds. Blackberry poses the greatest threat, but some sites are also heavily infested with sweet briar, St John's wort and other woody weeds including Cotoneaster and Photinia.
Loss and degradation of habitat and/or populations from browsing by feral and domestic goats.
Loss and degradation of habitat and/or populations from grazing by domestic stock.
Any species with such a small range and population size is vulnerable to disturbance (e.g. fire, drought), and the loss of even a few plants can be of major significance.
Loss and degradation of habitat and/or populations due to fire. In the early 2000s three of the larger populations were severely impacted by separate fires. Most of the adult plants and seedlings were killed within the areas burnt.
Loss of genetic integrity due to hybridisation with Grevillea rosemarinifolia along with woody weeds such as privet.
Abseilers trampling on plants and seedlings.
Current or potential future land management practices do not support conservation.
Some populations within larger patches of native vegetation are subject to heavy browsing by native herbivores, primarily wallabies.

Recovery strategies

A targeted strategy for managing this species has been developed under the Saving Our Species program; click here for details. For more information on the Saving Our Species program click here

Activities to assist this species

Protect known populations from changes to land use.
Eliminate browsing by goats and grazing by stock on sites where populations occur, fencing is appropriate.
Undertake weed control in and adjacent to populations, taking care to spray or dig out only target weeds.
Develop management agreements with landowners to ensure the species is managed sustainably on private land.
Monitor known populations for level of threats and population trends in response to management actions
Mark sites and potential habitat onto maps used for planning (rehabilitation and recovery).
Enhance small populations and/or establish new populations within suitable secure habitat
Undertake comprehensive seed collections from representative populations for long term storage as a future source of propagating material for use in translocations/enrichment plantings, if needed.
