Lightning Swamp Bushland

Lightning Swamp is one of a number of major reserves located on the Bassendean Dune system north of Perth. It is 70 hectares in size; an A class reserve, located 11 km NE of Perth between Malaga Drive and Reid Highway in Noranda with best access via Matthews Close.

It contains a range of mixed bushland communities and is representative of the natural environment that once covered the Swan Coastal Plain before urban development cleared  vast tracts of Perth's bushland. It holds a diverse mixture of plant communities occur from winter-wet swamplands of Eucalyptus rudis and Melaleuca communities, areas of Corymbia calophylla forest, to upland sites containing Banksia ilicifolia and B.menziesii woodlands. 

More than 180 flora species have been identified including two priority flora (Macarthuria apetala, Jacksonia sericea) and a declared rare flora (Caladenia huegelii).

The bushland provides habitat to over 125 native fauna and avian species. A number of regional migratory birds, including the threatened Carnaby's Cockatoo, visit this bushland corridor due to its healthy and diverse vegetation. 

Lightning Swamp comprises a seasonal wetland, damplands and a perched wetland which support a higher diversity of aquatic and fringing vegetation in comparison to permanent wetlands. The site provides habitat to at least seven endemic frog species within the wetlands and riparian zones.

 

The Wetlands

 

Lightning Swamp has several main water bodies  lying across the site. These dry over summer.  

The perched wetland in the north east is in good condition. It tends to be damp all year round due to its peaty clay base with poor hydraulic conductivity.  Perched wetlands such as this (i.e. wetlands not connected to the ground water) are relatively rare on the Swan Coastal Plain.

The western wetland is shallow and its gradual slope has lead to the growth of fringing vegetation. 

The Wonga Road Main Drain traverses the site west to east.

Plant Communities

Lightning Swamp contains six distinct plant communities, giving the reserve a richly varied structure.

 

eastern wetlandZone 1: Flooded Gum Seasonal Wetlands.

The eastern seasonal wetland dominates this zone. 

Flooded Gum  (Eucalyptus rudis) and Moonah (Melaleuca preissiana) are the dominant tree species with the Christmas Tree (Nuytsia floribunda) also occurring in the region. 

Woollybush (Adenanthos cygnorum),  Regelia ciliata and Balga - (Xanthorrhoea preissii) dominate the shrub layer.

Zone 2: Banksia Woodlands

This area is typical of many Banksia woodlands of the Bassendean sands.  It contains declared rare flora.

The key trees are Firewood Banksia (Banksia menziesii), Candlestick Banksia (B. attenuata), Hollyleaf Banksia (B ilicifolia), Christmas tree (Nuytsia floribunda) and Prickly Bark (Eucalyptus todtiana).

Zone 3: Perched Wetland

The perched wetland in the north-east corner is surrounded by banksia woodland.

This zone is in good condition. Species such as Baumea articulata and Baumea arthrophylla dominate with Moonah (Melaleuca preissiana) forming part of the littoral community.

This is a transition zone between the banksia woodlands and the two seasonal wetlands.  Its dominant flora are Marri (Corymbia calophylla),  Moonah (M. preissiana) and the Common Sheoak (Allocasuarina fraseriana). 

Zone 5: Moonah - Hollyleaf Banksia Seasonal Wetland

The wetland in this zone is in excellent condition.

Terrestrial plants include Moonah (M. preissiana), Marri (C. calophylla), Hollyleaf Banksia (B. littoralis), and shrubs of Hibbertia sp, Balga (Xanthorrhoea preissii), Purple Flags (Patersonia occidentalis), Woolly bushes (Adenathos sp.) and Fan Flower (Scaevola repens).

 

Zone 6: Moonah Transitional Wetland

This area is similar to zones 1 and 4. It is generally dominated by Moonah, Marri, Hollyleaf Banksia and Nuytsia floribunda. The water tolerant species (M. preissiana, B. littoralis) are interspersed with woodland species. A shrub layer of White Myrtle (Hypocalymma angustifolium), Balga and Purple Flags form a mixed understorey.

Birdlife at Lightning Swamp

rufous whistler The Lighning Swamp wetlands attract a large number of waterbirds, whilst the banksia woodland, heathland and riparian fringe of the wetlands provides an ideal habitat for a large complement of bush birds.  Endangered Black Cockatoos are often sighted feeding and roosting in banksias and Flooded Gums.

The ephemeral swamps, with their inundated thickets, act as important roosting and nesting sites for waterbirds such as the Eurasian Coot, Purple Swamphen and Maned Wood Duck during winter.
