The Prom and the Parrot

Almost every Victorian has a soft spot for Wilson’s Promontory National Park, one of the state’s most iconic and visited parks. So to be asked recently to go on a hike in the less visited northern section of the ‘Prom’ I jumped at the chance, especially since we were there to look for the rarely seen Ground Parrot.

We started the hike at Five Mile Rd carpark just off the main road once you get inside the Prom. Here we walked east over undulating hills to Barry Creek campsite where we set up our base camp for the surveys. In the afternoon we hiked north along the Lower Barry Creek track for over 2km checking areas of low shrubs and heathland, the Ground Parrot’s favourite habitat, then returned back to camp. Most of the suitable habitat we found was not far from our camp so this was where we concentrated our efforts.

The Lower Barry Creek track was often hard to find!

 

Unfortunately we didn’t see or hear any Ground Parrots during the two days. We did however stop to talk to a lone hiker who we asked if he had seen any low-flying, stocky green parrots. When we described them to him he seemed certain that’s what he saw but some descriptions he gave us sounded dubious. Who knows?

 

The Ground Parrot is a very cryptic species, much like its closest cousin the once thought to be extinct Night Parrot. A plump bird, the Ground Parrot is green with heavy mottling of yellow and black and a distinct red patch above the bill. It is more often heard than seen, unless accidentally flushed out of heath and is listed in Victoria as threatened. The call (which I had on an app on my phone) is very unlike any parrot I’ve ever heard and for me sounds more like a Gerygone than a parrot. Information beforehand suggested the Ground Parrot calls at dusk and dawn so these were when we did the most of the surveys. What we didn’t realise until after the survey was they actually call more often half an hour before dawn and half an hour after dusk!

We did however see a lot of interesting plant and animal life as well as some stunning landscapes so it was still very much worthwhile going on the hike. Chestnut-rumped Heathwrens were very common in the low heath areas. I’d only seen a fleeting glimpse of them before so to see and hear them a lot was great. I got some terrible photos of some at a distance so I wont embarrass myself and put it on here!

There are plans for another survey next year and this time with the new information that has come to light hopefully some can be found/heard and counted.

Anyone who sees or hears a Ground Parrot around the Northern Wilderness Area of Wilsons Promontory National Park, Nooramunga Marine & Coastal Park and Cape Liptrap Coastal Park can download the survey and ID form from the Parks Victoria website.

Thanks go to Denise and Anthony Fernando, the Victorian National Parks Association and Denis Nagle for a great hike in a great location.

Swamp Skink

The Swamp Skink Lissolepis coventryi is one of my favourite animals but unfortunately is becoming increasingly threatened from human-induced changes to its wetland habitats as well as predation by foxes and cats. It is currently listed in Victoria as threatened under the Flora and Fauna Guarantee Act (1988).

Swamp Skink Lissolepis coventryi, Bass Coast, Vic

Swamp Skinks grow up to 250mm in length and have a distinctive colouration. It’s body is typically a light olive green colour with two prominent black stripes along its olive-brown back. Its sides are black with light olive spots and patches. It can be confused with other species, particularly the similar sized and patterned White’s Skink Liopholis whitii (see photo below).

White’s Skink Liopholis whitii, Hernes Oak, Vic

The habitat of White’s Skink is typically drier and it doesn’t seem to prefer wetland areas. The two skinks, however, were previously lumped together in the genus Egernia but recent studies have separated both these species from genus.

The current distribution of the Swamp Skink is the coastal plains of Victoria with populations extending slightly into coastal South Australia and NSW. The majority of these populations are highly fragmented and subject to increasing pressures. Swamps, wet heathland, saltmarshes, sedgelands and watercourses are the preferred habitats for the species and many of these have been drained for development or agriculture. Many of the small isolated patches of habitat left are subjected to further pressures from disease, pollution, weather events, poor drainage, amongst others. Some areas though have been protected and have a relatively stable population but much more sites need protection through habitat restoration, pest animal and weed control, and minimizing disturbance to existing habitats.

If you live along the coastal plain of far S/E Australia keep an eye out for this species and submit any sightings to relevant departments. A great platform for the general public to submit sightings is the Atlas of Living Australia.  This citizen science based website collects data on Australia’s flora and fauna from a wide range of sources and can be accessed for information on species as well.

A fantastic article to read in relation to their requirements and management is the Swamp Skink management guidelines for the Mornington Peninsula (Clemann and Robertson 2015).

Southern Africa

Some of you may be wondering why I haven’t posted for a while. Well, my family and I have just been to southern Africa and recently returned. I know my blog is usually to do with S/E Victoria but I thought I’d post here anyhow. I literally took thousands of photos on our trip, most being of wildlife, and below are some of these.

It was the first time any of us had been to Africa and we did have a few concerns before we left. These were mostly to do with our safety and health, especially travelling with our two girls aged 7 and 9 in a campervan for most of the time. We were relieved that these weren’t as much as a worry as we thought as long as we were smart about taking all the necessary precautions.

Our basic itinerary included four countries in almost three weeks (South Africa, Swaziland, Zimbabwe and Botswana) and we began by flying in to Johannesburg (or Jo’burg as the locals call it) in South Africa. Here we hired a campervan and began a two week drive along the eastern part of the country. In our view this was better than going on a tour as we had the flexibility to visit wherever we liked and to stay the night at spots which looked nice.

Map of holiday

Map showing the areas we visited.

There were some mind blowing sights in SA and the highlights of the two week drive were the Drakensberg mountains, Blyde River Canyon, St Lucia, Hluluwe Umfolozi NP and Kruger NP.

The first major highlight was the enormous Drakensberg mountains west of Durban. Rising out of the rolling hills this mountain range extends hundreds of kilometers north and south but some of the biggest peaks surround the tiny mountainous country of Lesotho. We unfotunately didn’t have time to visit this landlocked country but apparently it is beautiful and the way of life has similarities to some parts of highland South American cultures.

The escarpment below Lesotho in South Africa was an awe-inspiring sight with towering peaks and deep valleys. As it was winter it was very cold (often well below zero at night) but it was also dry as most of the rain falls in the summer period. This area is a good spot to observe the endangered Bearded Vulture but unfortunately we didn’t have much time and didn’t get to see any. We weren’t going to spend the night there in sub-zero temperatures in a campervan!

As you can see road safety is taken very seriously in South Africa

Another fantastic spot was the area around the forested seaside town of St Lucia. This area includes the World Heritage listed iSimangaliso (Greater St Lucia) Wetland Park. We touched on the southern part of the park and the area was abundant with birds and mammals. Hippos apparently were known to regularly walk down the main streets at night in St Lucia and occasionally their droppings were seen in the streets around houses and on lawns. They probably find the lawns very tasty.

We were lucky to see two male Hippos fighting in the water. There was some immense power in the fights but they didn’t seem to inflict much damage on each other, more bluff I think. Still wouldn’t want to mess with one!

Inland from St Lucia our next stop was Hluluwe Umfolozi National Park (actually two National Parks joined together). This relatively small park was loaded with an array of plants and animals and this was our first glimpse of the larger mammals iconic with Africa. The girls had their faces almost permanently plastered to the windows of the campervan as we drove through the park looking at them.

Next on the list was the small country of Swaziland. This country has a lot going for it such as several game parks, traditional villages, beautiful scenery and relatively good infrastructure. The border crossings in and out of the country were mind-numbingly slow though.

Driving back into SA we visited an unexpected highlight of our trip and one which is not very well known outside of Africa, Blyde River Canyon. We never imagined we would see something like this on our holiday and it left a lasting impression on all of us. Unlike Australia they don’t believe in many safety barriers at places like this so we had to keep an eye on the girls a lot of the time!

Not far from Blyde River Canyon on the lowveld (plains) was Kruger National Park, a massive 19,500 square kilometre game reserve and SA’s first national park. We entered just above the central part of the park and travelled south staying at four camp sites over five days. There was no camping outside the designated, fenced campsites for obvious safety reasons but during the day we did our own game drives in the campervan. One thing that slightly disturbed us was the fact that the campsite gates were left open during the day so anything could wander in! They did too! Some antelopes, monkeys, baboons and warthogs were regularly seen inside the camps.

Almost every kilometre travelled in the park resulted in a new sighting and a tick off our list. Occasionally a herd of elephants or some zebras would wander seemingly oblivious to our presence across the road directly in front of our campervan with squeals from our girls. Animals and birds were used to seeing gawking tourists and we could drive up to them pretty close before they ambled away. As the speed limit was 40km/hr on dirt and 50km/hr on bitumen there was not a single roadkill seen over the five days.

We often knew when there was a good sighting up ahead as there were usually a few cars parked haphazardly across the road with cameras out the window. Road rules were completely thrown out the window when something amazing was seen.

It was always good to see the critically endangered White and Black Rhinos but sad to read that in Kruger NP alone a few hundred are killed by poachers each year despite a major effort by wildlife rangers to catch the culprits.

White Rhinoceros. Kruger NP, South Africa. 31.7.2016 (3)

Kruger and a lot of other parts of southern Africa are unfortunately in the midst of a mild drought so many rivers and waterholes were low and animals tended to hang around these areas. It was the middle of the dry season as well so much of the vegetation was in the process of dropping their leaves. These two factors meant many of the animals were easier to see.

After reluctantly leaving Kruger we had to get back to Jo’burg in a couple of days to return the campervan so we could fly up to Victoria Falls in Zimbabwe. Vic Falls township was our base while we went on a four day package tour of Zimbabwe and Botswana.

The first night in Zimbabwe we visited a large restaurant called Boma where they served up traditional meals. Many of the dishes though included a lot of the game animals we saw in the wild such as Kudu, Buffalo, Ostrich and Crocodile so it felt wrong to try these! One thing I did try (with a lot of encouragement from the girls!) was a mopane worm, actually a caterpillar of the large Emperor Moth similar looking to the Witchetty Grub. I don’t recommend it!

The next part of our package tour was a boat trip down the Chobe River in Botswana. This was fantastic and allowed us to get very close to a lot of animals and waterbirds. There was also no shortage of Nile Crocodiles, some of which were pushing 4m in length, and the tour operator wasn’t shy about getting our dinghy close to some decent sized ones.

Many of the water birds were very similar to, and some the same as, Australian species. Birds like Glossy Ibis, Great Egret and Little Egret are the same species as ours. There were also Darters and Cormorants which superficially looked like our ones too but were African species.

This female Impala seemed like it was enjoying the attention from these Red-eyed Ox-peckers who were eating parasites off it. Not so much in its ear though!

 

This part of Botswana is one of the best places on the African continent to see huge numbers of Elephants and they didn’t disappoint. At one stage large groups of Elephants appeared out of the dry scrub and assembled along the banks for miles. They were used to seeing tourists so we got relatively close to them in the boat.

Elephant. Chobe River, Botswana. 5.8.2016 (8)

Elephants on the Chobe River.

Several groups of Elephants started to nervously enter the water, most likely checking for crocs first. They then began to swim across the river in single file to reach the green grass on the islands in the centre. One young one who couldn’t reach the bottom was coaxed along by the mum at the back who occasionally dived under the youngster and lifted it out of the water while it alternated between using it’s trunk as a snorkel and or holding onto the dad’s tail with it’s trunk.

Yellow-billed Stork and Black Heron, Chobe

This Black Heron had an interesting relationship with the Yellow-billed Stork. It would follow the stork around and when the stork probed the ground it would fan its wings. Any small invertebrates or fish would try and seek shelter from the stork under the heron’s wings which it would then eat.

 

After the boat trip we piled into an open-aired safari car and went on a game drive of Chobe National Park. This park was much drier and sandier than Kruger so it was interesting to see a lot of different species. Another species seen which is similar to an Australian one was the Kori Bustard, Africa’s largest flying bird and national bird of Botswana. This is very much like the Australian Bustard’s plumage but is larger than our species.

On one of the days we went on a three hour paddle in an inflatable raft down the Zambezi River which bordered on one side with the country of Zambia and the other with Zimbabwe. Apart from our guide and a rower we were the only ones in the boat so it was good to sit back and take it slow for a change. We didn’t see as much wildlife as on our boat trip down the Chobe but we all had a nervous moment when we came out of a set of small rapids into flat water to find a Hippo not far away from us. The guide and rower exchanged some nervous looks and hand gestures and they managed to move us away without any trouble.

P1140185

One place high on almost every visitor’s list in Zimbabwe is Victoria Falls, the world’s largest waterfall. It’s native name is Mosi-oa-Tunya which means ‘the smoke that thunders’. This comes from the enormous cloud of mist thrown into the air by the force of the water hitting the base of the gorge. Nothing could prepare us for the enormity of the falls and halfway along the top of the walking track it seemed like it we were caught in a windy rain storm as the billowing mist saturated us in seconds. On our last day we went on a helicopter flight over the falls and got to see it and the town in a different perspective.

In the township of Victoria Falls wild animals were free to wander into town and we saw a few different species in the streets including a small herd of elephants one night wandering on the edge of the main street. Talking to one local he said lions have been known wander the streets but they know that if there are buffalo moving into town there are lions around. This is because buffalo feel protected from lions in towns. A very crude early warning system and not one I’d trust 100%!!

The town is set up primarily for the tourist trade and is not all that big in size. It’s a bustle of activity for both tourists and locals but not far out of town life is much slower and the way of life more traditional. We visited a village where families still live in grass and mud huts.  One family showed us around their small patch of land of about 1 acre and it opened our eyes to how difficult it is for them to live off the land and support their family. Water needed to be carried from a well nearly 1 km away and food was a struggle to grow in the very impoverished soil. Not only that but they had to deal with bird flu a while ago where all the poultry in the village died. To make an income so they can buy extra food and other items they can’t produce themselves many of the villagers make crafts to sell at Victoria Falls markets or they transport animal manure to local farmers with donkey and cart. We definitely take our own luxuries and way of life very much for granted.

Southern Africa was well worth the visit and I’d recommend it to anyone who hasn’t been yet as it will blow your mind. As long as you research the areas you will travel and speak to locals if you have any concerns it’s reasonably safe and hassle free.

..and yes, if you’re wondering, we did see the big five (Lion, Elephant, Buffalo, Leopard, Rhino) but were amazed how much it was plugged at every tourist place we travelled!

Leaf-curling Spider

During summer a common sight in southern and eastern Australia’s woodlands, open forests and urban gardens is an untidy and almost circular web strung between vegetation with a curled leaf seemingly caught in its centre.  This is usually the workings of the Leaf-curling Spider Phonognatha spp.

Leaf-curling Spider Phonognatha graeffei outside of its Eucalypt leaf shelter. Morwell, Vic.

There are currently 7 species of Phonognatha recognised wordwide with 4 in Australia. By far the most common and widespread in Australia is P. graeffei (pronounced greef-e-i) which is found in Tasmania and along the entire east coast of Australia to South Australia. Males reach a body length of about 6mm and females 10-12mm. They currently belong to the Orb-weaving family Araneidae but there is ongoing debate as to whether they should be in this family or not and in the past the genus has being placed in other families.

Phonognatha graeffei

Leaf-curling Spiders, after constructing a web, will haul up a leaf from the ground at night using a silk line and attach it to the web. This is then curled up with more silk until it forms a shelter in which to hide. The top end is closed with silk and the base is open. I’ve noticed Eucalyptus leaves are favourites with this species in Victoria but I have seen them use Snowy Daisy-bush Olearia lirata and Hop Goodenia Goodenia ovata leaves as well. Occasionally other items such as paper or even an empty snail shell are used instead.

Once the leaf shelter is completed the male will shift in with a female or sometimes live close by. This is typically an immature female who lives in the top part of the leaf while the male guards the entrance from rival males and catches insects caught in the web.

As soon as the female reaches maturity the male mates with her, occasionally resulting in the male being eaten. This female then moves out and constructs her own leaf shelter amongst nearby vegetation where she will lay her eggs. As with most other ‘modern’ spiders (Araneomorphae) they have short lives and both the male and female Leaf-curling Spiders will die at the end of summer to be replaced by their children.

Once hatched, the spiderlings themselves will begin hoisting up small leaves as practice for when they are ready to shift out of home and begin the process all over again.

Gippsland’s Reptiles Part 3- Dragons and Monitors

This is part 3 of a photo essay on Gippsland’s unique reptiles, this time to include dragon and monitor (goanna) lizards.

Although not highly diverse as much of the rest of Australia, particularly the arid parts of the continent, Gippsland’s dragon lizards (family Agamidae) include a handful of interesting species. Their distribution extends throughout the Gippsland region and each has specific habitat and diet requirements.

On the coastal plain of Gippsland you are likely to come across the well camouflaged Jacky Lizard Amphibolurus muricatus, particularly in the drier woodlands and coastal parts of the region where it can be found on the ground or perched on branches. It is found in the coast and ranges of SE Australia from South Australia to south east QLD.

Jacky Dragon- Amphibolurus muricatus. Dutson Downs, Vic. Heathy woodland. 16.9.2015 (1)

This species is relatively common in open woodlands and coastal scrub and can be easy to miss when walking through these areas as it blends in well with its surroundings. Growing to a total length of almost 400mm it is very similar to the much smaller Mountain Dragon Rankinia diemensis which also occurs in the region. Jacky Dragons can be identified from this species by the inside of their mouths being bright yellow as well as having no enlarged spines at the sides of the tail base. Mountain Dragon’s mouth is blue inside and they have small spines at the sides of the tail base.

Jacky Dragons have a peculiar way of communicating with each other which include complex movements such as head bobbing, arm waving, push ups, body rocking, tail flicks and colour changes. When disturbed they sometimes run upright on their strong back legs to escape at speed.

_________________________________________________________________

The Mountain Dragon, as its name suggests, is typically found in high country but can also extend to the foothills and some parts of the nearby coastal plain.

As with the Jacky Dragon they are very well camouflaged and difficult to detect due to their ability to change their colour to their surroundings.  Mountain Dragons feed almost primarily on small insects found in leaf litter and low vegetation of dry woodlands. I have often seen them in the high country perched on the top of small termite mounds feeding on termites. This is a small dragon and can grow to a total length of up to 200mm.

When travelling along rivers and large streams in Gippsland you are often aware of frequent splashes in the water. This is often due to the presence of the large Gippsland Water Dragon Intellagama lesueurii howittii, a subspecies of the Eastern Water Dragon which is common along the east coast of Australia and is a semi-aquatic species.

Gippsland Water Dragons inhabit rivers, streams and sometimes rocky intertidal areas of the coast. They frequently perch on rocks, logs and branches overhanging the water and will often use these for a quick access to the water to hunt or escape predators, similar to the freshwater turtle. They have a strong swimming ability and is reputed to be able to remain underwater for over an hour! It feeds on a variety of terrestrial and aquatic species which includes insects, aquatic organisms, small vertebrates such as frogs, lizards and mice as well as fruits and berries.

Gippsland Water Dragon- Physignathus lesueurii howittii. Yallourn, Vic.  5-2-10 (3)

Water Dragons look almost like a swimming snake when they take to the water.

Gippsland Water Dragon males can grow to almost 1m in length and weight up to 1kg. Males have a brilliant colour pattern in the breeding season which includes a bright orange and green blotched neck and green overall body colour with striping on the tail. The Eastern Water Dragon male typically has a reddish pattern on the neck and chest, a dark patch behind the eye and more prominent stripes and the tail and back. It also tends to lack the green body colour of the Gippsland subspecies. Several feral populations of the Eastern Water Dragon have been found in South Australia and Victoria, including Gippsland (Yallourn), presumably escapees from reptile breeders.

The Lace Monitor Varanus varius is a large species of goanna found throughout Gippsland but is becoming increasingly rare in the western part of the region. As such it is listed as threatened in these parts. In central and eastern Gippsland, including the high country, Lace Monitors are still quite common in forest and woodland and will often hang around campsites or rest stops looking for scraps. Individual can have a large home range of up to 1-2 km² in summer but will remain almost dormant in winter. They are semi-arboreal and will often climb trees to raid nests of birds and mammals and will often use large hollows to shelter in.

Lace Monitors are very adept at climbing using their large claws. Heyfield, Vic.

Lace Monitors are one of the biggest goannas in Australia and males can grow to a total length of over 2m. Their name comes from the network of stripes on the body and neck which can vary in colour and pattern. The typical overall colour is dark grey with a complex series of creamy-yellow spots often merging into stripes. The neck and underparts are cream with dark grey stripes or blotches. Some individuals have a blue tinge to the body, especially the throat.

Another species, Gould’s Sand-Monitor Varanus gouldii, has historically been recorded from far east Gippsland but this hasn’t been seen for decades and it apparently wasn’t a common species in this area.

Dragons and monitors probably evolved on the same lineage as snakes very early in reptile evolution in the Cretaceous period. In fact, monitors are the only lizard to share the forked tongue with snakes which they use to smell scents and it is thought that these two are closely related.

Although not as common as Gippsland’s skinks, the dragons and monitors of the region are always a pleasure to see.

The secret life of the paddock tree.

The majority of prime agricultural land in southern Australia was once densely vegetated with scrub, woodlands or forests, typically dominated by eucalypts. In Victoria’s Gippsland region, one of Australia’s most fertile areas, most of the land has been so highly modified from clearing it is often difficult to determine what the original vegetation communities were. The only way to do this is to observe the handful of remnant species remaining to work out the original EVC (ecological vegetation class) and this vegetation is often in the form of the paddock tree.

This drastic change to the landscape is unfortunately typical of a lot of agricultural land in Australia. Throughout the late 19th and early 20th century the clearing of vegetation in southern and eastern parts of the continent was on such a grand scale and in such a relatively short period of time that many species, both plant and animal, had no time to adapt to this change and an extraordinary amount of species became extinct or threatened. According to the Victorian Environmental Assessment Council VEAC Report 2011 it has been estimated that 30% of Victoria’s native fauna and 44% of native flora have become extinct or threatened with extinction.

In Gippsland, the Strzelecki Ranges and nearby foothills originally consisted of mostly wet or damp forest which before European colonisation was seldom touched by fire, unlike the grasslands or drier forests and woodlands of the Gippsland plain which were periodically burnt by aboriginal people.

In the late 1800’s to early 1900’s these moist slopes were beginning to be transformed into bare rolling hills by the white settlers who were allocated small allotments. These had to be cleared of a certain percent of their vegetation in a short period of time, otherwise they forfeited their rights to occupy the land. At first this was done by axes and saws which must have been an enormous task but later was done by burning the forests to open them up and make them easier to manage and clear. Wet forests are less able to adapt to intense fires and much of the vegetation didn’t recover. These bare areas were then transformed into grassy paddocks where stock and crops were farmed.

The expansion of rail lines into South Gippsland in the 1890’s created an exponential amount of settlement in the area and subsequent clearing of forests for towns, roads and agriculture. This has resulted in a patchwork of often isolated vegetation in the form of ‘island’ reserves, parks, roadside remnants and the topic of this blog, the paddock tree.

Native paddock trees, however isolated they are, are important in the ecosystem as they provide food, shelter and protection for a wide range of species. Bats will use tree hollows or loose bark for roosting and rearing young. Koalas and possums will often travel over open farmland to utilise isolated trees and many birds will use these to feed or nest in or as stepping stones when accessing other sites.

The Koala often has a wide home range and will travel over open paddocks to access isolated trees.

In agriculture remnant paddock trees can be important for productivity, particularly when farming livestock as these trees provide protection to stock from the elements (less stress=more productivity). So why don’t we put more effort into protecting these assets if they’re so important? Some farmers do a great job at protecting these remnants, often depending on how active or well-funded their local Landcare group is but others can be negligent or misinformed in their approaches.

The problem with many native farm trees which become isolated is that they are more susceptible to diseases, parasites (insects, mites, nematodes and some plants), insect damage, stress from the elements, browsing pressure, excessive use of nitrogen-based fertilizers, drying out of soil, compaction of the ground and rubbing from livestock. A recent study by scientists from Deakin University looked at koala populations and their browsing pressure on Manna Gum Eucalyptus viminalis. It found an initial increase in density of Koala populations resulted in severe browsing of these trees within a small area. This in turn caused a catastrophic drop in Koala numbers due to starvation. Insects also can have a major effect on tree health due to lack of predators and can cause extreme defoliation, root or basal bark damage and are often attracted to an already stressed tree as this is when the tree’s defences are down.

All these above  factors can result in the slow death of the paddock tree with no recruitment of seedlings. Some farmers see their native trees are dying and plant exotic species such as Pines which are less prone to being attacked. But there are steps property owners can undertake to protect isolated native trees while still being productive both in an agricultural and ecological sense.

Remnant trees and other vegetation can be protected firstly by fencing off stock to avoid damage from soil compaction, browsing and rubbing, erecting the fence at least from the canopy-width out from the tree (ideally twice the width of the canopy). By allowing stock to still use the protection of the tree, but excluding them from compacting it’s roots, the farmer still benefits. Whether it’s an isolated patch of vegetation to be created or ideally a corridor the simple recipe for success is a diversity of species to be planted and adequate weed control. This includes trees, shrubs and larger hardy grasses, all of local province. Smaller shrubs, herbs and grasses can be added in the future once the canopy is relatively established and some minor weed control is continued.

Due to the 5 year accumulation of leaf litter and dense canopy layer there is no more need for weed control and there is already a recruitment of species from self-seeding.

One mistake that many well-meaning landowners or groups do is lack diversity in their plantings. By having an array of nectar-producing plants, species like honeyeaters, bees, wasps and butterflies are attracted to feed on the flowers. Birds such as parrots and Silvereyes are attracted to fruiting plants and seed-producing plants like grasses attract native Bush Rats and Rosellas, among others. The leaves of different plants often have specialist insects which feed on them and this insect fauna attracts predators such as spiders, reptiles and a wide range of birds. Then there’s the protection from predators and nesting opportunities the plants provide.

All these factors protect any remnant isolated trees from damage and allows the tree to hopefully produce viable germinates and successive generations. Additional vegetation will protect the tree by also increasing the soil’s microbes, humus layer from leaf litter and protection from the elements. By attracting a diversity of fauna to a patch this in turn will protect the vegetation from pests as there will be more predators to keep them under control.

A common example of imbalance with isolated trees is the prevalence of the parasitic Australian mistletoe. The widespread Mistletoe Bird feeds on the fruits of the mistletoe and will often target isolated trees or trees on the edge of a remnant patch. The seeds of the fruit are excreted on the branches of the isolated tree where they grow and often infest the tree to the point of death. This is due to a lack of mistletoe predators in open areas such as some of the Jezebel butterflies Delias spp whose caterpillars feed primarily on mistletoe leaves and keep them relatively in check in healthy bushland.

Unfortunately, paddock trees are a dying breed but without more education and funding available to farmers and other landowners we’ll keep losing more and more of them.

The Knob Reserve, Stratford

Although it’s got an unfortunate name, the Knob Reserve in Stratford is a hidden little gem tucked away behind the town. This park is 56 hectares of mostly Gippsland Plains Grassy Woodland, an EVC (Ecological Vegetation Class) which is threatened and few relatively intact remnants remain in the region due to clearing for agriculture.

Historically this park is very significant to the indigenous Gunaikurnai people and has been a traditional meeting place for thousands of years. The ‘knob’, a prominent bluff along the banks of the Avon River would have been seen a long distance away. Evidence of their occupation can be found on and around the bluff including scar trees (trees with bark removed for canoes or shields) and sandstone grinding stones which were used to sharpen tools such as axes.

Early spring is the time when this area comes to life and although the grass is still green from winter it doesn’t take long for the soil and vegetation to dry out to a crisp. When I visited last week a lot of the herbs, lilies and orchids were in full bloom and the birdlife was extraordinary.

The Bulbine Lily Bulbine bulbosa was particularly common and the large yellow flowers could be seen dotted everywhere.

Chocolate Lilies Arthropodium strictum were also very common but only just beginning to form flowers and I think if you went back next week it would be a haze of purple.

This reserve has a high number of Donkey Orchids Diuris spp, one of them, the Purple Diuris Diuris punctata is listed as threatened. Although there weren’t any I could see flowering yet the photo below is from another trip I did to a grassland reserve near Bairnsdale the next day.

Leopard Orchids Diuris pardina and Golden Moth Orchids Diuris chryseopsis weren’t common but scattered in the denser grasslands.

Like I mentioned the birdlife was amazing and within half an hour I had a tally of nearly 40 species! Parrots in particular were everywhere and many were searching for nesting hollows in the old Red Gums.

We’re heading back to this reserve next week for work and it should be great to see what else might pop up.
