Towards a seasonal calendar

Observing…

As anyone who lives on the Fleurieu would have observed, our seasons do not really match the classic four seasons of the European calendar. Our hot “Summer” weather lasts well into mid-Autumn, our “Winters” are mild and snow-free, our “Spring” flowers often blossom in August, and prevailing winds change direction at different times of the year.

The Kaurna Seasonal Calendar, from the Bureau of Meteorology Indigenous Weather Knowledge project.

It makes sense that bioregions need their own calendar, and in our region, the Kaurna seasonal calendar provides an insight into the patterns of our landscape. In contrast to the fixed three-month quarters of the European calendar, the Kaurna calendar instead is responsive to a critical mass of natural phenomena being reached: the life stage of certain plants, the movements of animals, as well as the prevailing winds and weather patterns. Some seasons may not occur at all in some years. Such a calendar indicates a breathtaking depth of landscape knowledge. The Kaurna seasons are described by Scott Heyes in his thesis, with versions also published in Adelaide: Nature of a City, and Adelaide: Water of a City, available at your local library! Artist James Tylor has also written a fantastic summary of the seasons and associated wild foods. The calendar is also documented in the Bureau of Meteorology’s Indigenous Weather Knowledge project.

The four main Kaurna seasons are:

Warltati – approx Jan-March – Hot season
Parnati – approx April-June – Windy season
Kudlila – approx July-September – Wet season
Wirltuti – approx October-December – Mild warm season

The complexity and depth of Kaurna knowledge of landscape and seasons is astonishing. As recalled by one colonial observer “WGR” on the Fleurieu, during the gold rush, many white men on the Fleurieu left for the gold rush in Victoria. This saw a period when Aboriginal people assumed much of the work on settler properties throughout the region. WGR describes how, “The youngsters went hunting and fishing with the natives, and learnt a lot of things unknown to the average white about birds, animals and fish. Shoals of mullet visited the coast at times. Dick [an Aboriginal worker] promised to let us know when they were coming. One night he roused me up … Off we went, and sure enough there were great numbers passing along the sandy beach going south. Asked how he knew it, he pointed to a particular star in the south-east. “Yes, but how about this?” “Well, my father tell me.” It is remarkable that more than 60 years afterwards an aboriginal gave the same reply regarding the movements of another variety of fish.”

Inspired by the depth of Aboriginal seasonal knowledge, we came across the ‘Seasonal Signpost Calendar’ concept by artist Sofia Sabbagh. She describes it as “a means to track and cultivate the noticing of our environment; native and non-native species, and to link our personal lives with the cycles of our environment”. To support this, Sofia suggests a series of questions:

  • What is changing in my local environment?
  • How is the soil?
  • How is the creek?
  • Which birds are appearing?
  • How might this environmental change affect another plant or animal? What is the flow on effect?
  • Which plants/animals do I notice?
  • Which plants/animals appear in significant times of my life?
  • Which plants/animals do I most obviously affect?
  • Which plants/animals most obviously affect me?

Inspired by Sofia’s calendar, for the past 12 months we have been observing and recording all the changes we notice in soil, moisture, weather conditions, fungi, plant and animal life.

The Yarnauwi Seasonal Calendar, now in its second year.

Now we are into our second year of the calendar, patterns are starting to emerge. For example, it turns out that the pair of Adelaide Rosellas which we thought we saw sporadically actually consistently stay on the property from May-August and we see them every visit, and then they go somewhere else. And we start worrying about the Wedge-tailed Eagles when we don’t see them for awhile, but it turns out that summer is more commonly when they soar above us, whereas the Nankeen Kestrel is year round. And all our various species of Acacia/wattle started flowering in the same week this year as they did last year, despite the fact that we had a wetter year.  

The climate and landscape-responsive Kaurna seasons provide a central touchstone for our own observations.

We are really interested to see where this calendar takes us, especially as we start to get an understanding of what environmental phenomena trigger other environmental phenomena. This will help us plan when we need to do work tasks (planting at the best possible time, slashing turnip weed before seed set, collecting native seed, making sure our bees have enough pollen and nectar options etc), but more importantly help us develop that deeper connection with the land. We really want to know how the ecosystem all fits together and how everything is synchronised so we can work with the land not against it.

New growth on a red gum sapling.

We’ve been talking a bit recently about when a woodland becomes a woodland. Asher suggested 500 years of growth, but was willing to settle for 50. Perhaps it’s a woodland when the birds think so, when the firetails and blue wrens jump the boundary fence from neigbouring scrub and decide they’re safe flitting from branch to branch. As our earliest plantings grow taller than humans, and the canopies thicken and throw shade, we started noticing an increasing diversity of tiny life. Insects for whom a gum or wattle tree is their universe are finding their way across the paddocks to settle in the emerging plantings. Despite the heat and dry of summer, the trees are heaving with insect life. We recently saw the documentary The Biggest Little Farm about an idealistic (and evidently well-funded!) couple who start a diverse 200 acre farming project outside of Los Angeles. One of the messages of the film is that when you create the right conditions, nature finds a balance. As we walked through the saplings, on one, the new growth and leaves were being systematically devoured by small copper coloured beetles. We walked to the next tree, the copper beetles were present, but as we watched, were body slammed by wasps and carried away. At the next, the beetles had been busy, but now a spider had arrived, and was meticulously wrapping the beetle population in silk. Perhaps these tiny communities are beginning to find the balance too.

Here’s a tour of some of the life on the trees – we’d love your help with identification!

Year of Fire: Annual Report 2020

A melted tree guard shrink wraps a seedling after a fire move through part of the property in January 2019.

2019 began and ended in fire. In early January, some errant fireworks set off by passers-by landed in one of our front paddocks, burning across a couple of hectares of our property. We were lucky. There was little wind, and it was quickly noticed and contained by our amazing neighbours and the CFS. Meanwhile, in Tasmania, fires ripped through the forests, and by spring and early summer, vast tracts of the east coast and Kangaroo Island were catastrophically aflame once again. While we’ve escaped the drought and bushfires that have gripped so much of the continent, these phenomena have served to focus our goals and aspirations in 2019. It’s been a year of learning as we work towards a more regenerative approach: ultimately building soil and harvesting water and carbon in the landscape.

2019 had the dubious distinction of being Australia’s hottest and driest year on record. It got pretty warm in the shed.

Learning
Our regenerative aspirations have been focused by some outstanding events this year. In June, we attended the Deep Winter Agrarian Gathering in Willunga, drawing together 150 aspiring and established regenerative farmers from around Australia to share skills and ideas. Former CSIRO microbiologist and climate scientist Walter Jehne set the tone with a rousing and inspirational keynote on restoring natural processes through agriculture to cool the climate.

Not ‘if’, but ‘when’: planning for fire

A few evenings ago, someone set off fireworks on the road beside our property. Embers from the fireworks landed in the grass on the property boundary and quickly took, spreading through the dry summer grass along the fence and down a drainage line. Thankfully, our neighbours quickly noticed and set to work with their own fire unit while awaiting the arrival of the police and Country Fire Service. The blaze was contained with minimal damage, but it’s stimulated us to revisit our property plans and consider how we’re designing for the inevitability of fire.

Blue gum (Eucalyptus leucoxylon) seedlings ready for planting.

Before Yarnauwi, we never really appreciated winter. Now, through the long dry season, we find ourselves yearning for a chill edge to the wind, the moisture in the grass, and skies of dark clouds. We’ve tried to plan our year to mimic the lives of so many of the organisms that occupy our landscape: in the hot, dry times, we go into maintenance mode, watching and waiting for the first rains before we spring into action again. With the greening of the landscape, it’s all on: tree-planting has begun, shed sites are levelled, the grass grows. In winter, the kangaroos converge in clans numbering hundreds, displaced from the pasture, they lounge among the seedlings in the reveg areas while we look on nervously.

A new (moveable) sheep shelter

We’ve tried to structure our farm year so that summer is a time of dormancy, maintaining the property, but avoiding too many big jobs in the heat. With an historic heatwave across southeastern Australia, and four consecutive days over 40 degrees for South Australia, we thought we’d make an exception to construct another shelter for our long-suffering sheep.

Local Adventures: Kalamunda Native Forest Reserve

Looking towards Yankalilla Hill and The Gorge, Normanville from the northeastern corner of Kalamunda Native Forestry Reserve. The radio masts of Yankalilla Hill (the cliffs above Lady Bay) are just visible on the left of the photograph.

We pulled in at gate MH18, 50 metres from the summit of Mount Hayfield at the northern end of Mount Hayfield Road (off Springs Road, from Range Road). Through the pine plantations we could see flashes of sky and the brown paddocks stretching off to the north. It’s up in the highlands here, and where it’s not grazing land or forestry plantations, there’s still patches of native forest, the most significant of which is the Kalamunda Native Forest Reserve, part of the Second Valley Forest complex.

Continuing our research into the ecology of the Fleurieu, we’ve been looking for examples of what our own landscape might have looked like before clearing to help guide our regeneration efforts. Of the three local forest reserves, Kalamunda seemed like a good fit. Perched above Yankalilla, Kalamunda is a fragment of the kind of woodlands which were present across the Fleurieu.

The time of plans and projects

Grain fields at Aldinga, and drying hills

It seems like summer comes sooner and sooner. Winter was short, and so dry that the dam never progressed beyond a puddle, then the sun was back, the grass grew for a moment then was baked dry again by an early heatwave. The northern faces of the hills turned a bleached gold, then quickly the green haze on the south sides followed. And we’re back, heading into the hot season again, settling into a holding pattern of heat and dormancy until the opening rains.

IMG_7058

North faces baked dry in the first heat

Tolstoy apparently called spring “the time of plans and projects”. Now a year into our sheep project, we’ve begun tweaking our grazing practices in an effort to manage our pasture more effectively. We’ve increased our flock size through both breeding and the acquisition of some hardy, desert-adapted damara sheep, brought in from a dusty paddock outside Nuriootpa to replace the ageing and increasingly delicate Wiltshire Horn matriarchs. The existing flock hasn’t exactly embraced the new arrivals, there’s plenty of bleating and foot-stomping. You could cut the tension with a knife when we pour out the sheep nuts. Among the damaras is Manchego, our new ram. Looking at Pecorino’s legacy, it’s clear he has big hooves to fill.

The rain gauge almost full!

With the big rains of the last couple of weeks, it feels like we’re approaching an break in the seasons. In most parts of the property, the cracks that open in the clay over summer are softening and closing, and there’s a green fuzz of new growth on the ground (especially in the areas with existing, dry ground cover, we’ve noticed). The sheep march briskly between discoveries of fresh grass and happily fan out over new paddocks.

The magic hour hits the cliffs at Lady Bay.

It’s now officially autumn, and already the air feels a little different. There’s a cool edge to the mornings, and a hint of moisture to the air. The land still feels dry, but we tell ourselves it won’t be long now.

From where we'd rather be...actually there's nowhere we'd rather be! Big thumbs up for the kids' new hammock under the old gums. So glad to finally be here at last! Happy 2023 all 🌿
First fig of the season. A monster Black Genoa, organically grown in our little windswept orchard.
As proof of the recent confusing weather patterns, these Amanita mushrooms came up a few days ago! We've never seen mushrooms here in November, they're usually all finished by August, and we've never seen this species or anything like it here before! Amanitas are mycorrhizal (they form a partnership with a tree/plant to help feed and nourish it in exchange for sugars) and these ones were growing only 1m or so from a Eucalypt we planted about 7 years ago which has always grown really well. I just wonder if this species has been there all along, waiting for perfect conditions of 45mm in one day in Nov to be able to fruit! And now it can reproduce and spread to other parts of the farm. It makes me wonder what else is out there ready to take advantage of crazy climactic conditions!
As long time admirers of @thegreenhorns we're thrilled that Joel's comic about weeds will be published in Vol. VI of "The New Farmer's Almanac". It all releases this January and pre-orders are available now through @chelseagreenbooks
Frog spawn! 🐸 We've never seen this before at Yarnauwi but with the best rains in years our dam is filling up, the air is full of the calls of the Spotted Grass Frog and the Common Froglet, and we seem to be providing enough grassy water habitat for these eggs to be laid with enough shelter for them to grow into the little black tadpoles you can see inside! Lying next to the dam listening to frog calls definitely takes us to our happy place and makes it all so very worthwhile 💚
2022 marks a decade since we started working to regenerate Yarnauwi. To celebrate Joel's been working on a little comic to acknowledge all the amazing folks in our community near and far who have supported us and this place over the last 10 years. Here's a sample, but the whole thing is on our blog - follow the link in our bio!
Thanks to everyone who came joined us on our farm tour as part of @historyfestival and @heritagefleurieucoastfestival - we really appreciate your interest and enthusiasm!
We're honoured to have this story pop up on @abcnews_au sharing some of the work we've been doing to regenerate our patch. Our deepest thanks to all the friends, neighbours and family who have helped transform the property over the last decade!
It's been a good year in our little orchard, with plenty of ripe figs for us - and others! Here's one we found, positioned just like this on top of a fence post. I'm looking for a raven with fig juice running down its chin.
