Sun and rain, Winter 2014

Watching the light shift across the hills is one of the great pleasures of being on the South Western Fleurieu, and it’s further enhanced by proximity to the sea. On our journeys around the region, we’re regularly exposed to the changes of light over the ocean as the road hooks coastward at places like Lady Bay or Sellicks, or hiking along the cliffs and coast around Second Valley. Summer offers a starkness to the ocean and sky, but I’ve come to love the way sea and sky diffuse together in the winter. Here’s some of what we’ve seen.

This is the first instalment in an occasional series celebrating different plants of the Fleurieu, particularly those that we spot or try to reintroduce to the farm. It’s also a way for us to map and share our research and discoveries as we observe the regeneration of our property.

sundew

During our recent winter tree-planting extravaganza, Sean, one of our dedicated tree-planters, discovered a patch of Scented sundews (Drosera whittakeri), in the damp, mossy undergrowth around the gullies. With its distinctive white flowers, once we’d spotted one cluster, we discovered more in similar damp pockets. Continue reading →

The ‘before’ photo: 800 new plants in position. Stay tuned over the next 20 years for the ‘after’ shot.

Over the weekend of the 12-13 July, around 30 dedicated volunteers descended on TBC for our annual tree-planting fiesta. Over two days, we managed to plant some 800 locally indigenous plants in the two ‘wilderness zones’, kick-starting their transition back to pink- and red-gum woodland. The first area was planted outwards from the former Bee House (currently tree-planter snack dispensary and rain shelter) with around 600 plants selected to address the water-logging in the area and to revegetate in and around erosion gullies. The second area saw the planting of around 200 plants, radiating from the existing remnant redgums. Once again these plants were selected to address water-logging and erosion as well as provide shelter to adjacent paddocks. Over the following week, we dodged thunderstorms and icy squalls to add another 150 or so plants, with about 200ish to go!

Birds of the Block embroidery project

White-faced Heron, May 2014

White-faced Heron, May 2014

A tradition has officially started now that I’ve done it twice. Each year, in honour of Joel’s birth, I shall embroider a different bird species found on our property to add to a home wall gallery. Joel asked what the criteria is for birds to be selected: they have to be interesting, native, and not commonly found in the city (even though they can be common on the Fleurieu). I can’t bring myself to embroider pigeons or magpies, though we have plenty of both. The idea is that I shall never run out of birds to embroider, as more and more birds will flock to our property as it becomes ever more diverse and abundant! The key bird species we are hoping to attract at the moment are yellow-tailed black cockatoos (which currently fly straight over and go and eat pine nuts in the pine trees in the Second Valley beach carpark) and the little finches we see hanging out in the Wirrina reveg area just across our back fence line. So stay tuned for next year’s installation!

If a tree falls…

IMG_3799A couple of months after the central third of our biggest remnant red gum crashed to earth, I climbed into the centre of the fallen limbs to try to remove some timber for erosion control structures. I was surrounded by the faint, constant pattering of distant rain. The tree was rustling, but no wind moved the leaves. I put my ear to the boughs and realised the sound was coming from inside, exhaling as the timber dried and cracks slowly opened in the bark. Meanwhile, in the leaf litter below, the spiders and beetles delight in the thick undergrowth of their new canopy. Continue reading →

Erosion control: 15 months on

One of the first interventions we made on the property was trying out some very rough erosion control on this scoured patch on our boundary. Earthworks from recent fencing had disturbed the soil and invited headcuts to form. With help from Pete and Freya, we tentatively set up a couple of lo-fi erosion strategies, informed by the work of Watershed Artisans (formerly Dryland Solutions) and Brad Lancaster, both of whom we’ve gushed about before. We reshaped the main headcut to soften the overflow, and positioned some kind of mutant One Rock Dam/Zuni Bowl at an intersection between two small headcuts – not something I’d do again. We also positioned a One Rock Dam on contour above the entire area in an effort to slow and disperse water flow.

New artwork: painting summer

Second Valley causeway, looking towards Normanville.

A little while ago, it occurred to me that maybe I should give watercolour a crack. The theory was that I’d be able to work fast enough to bang out a painting during toddler naps. In reality, I’ve still only finished a handful of works over the last six months, and as a consequence my skill development has been glacial. That said, it’s still a pleasure to sit down with the brushes and attempt to wrangle the Czech-made watercolour set into South Australia’s less exuberant colour palette.

A One-Page Place Assessment for TBC Farm, Second Valley

Brad Lancaster’s books on Rainwater Harvesting would have to be among the most consistently inspiring books we own. Two volumes into his trilogy on Rainwater Harvesting for Drylands and Beyond, Lancaster combines accumulated community wisdom with permaculture principles to produce lavishly illustrated, practical and highly accessible manuals for managing water in urban and rural environments. Consistent with permaculture thinking, Lancaster urges land managers to spend time observing the season patterns of the landscape to more effectively design for sustainable, integrated water management. One method of doing this is to compile a One Page Place Assessment, drawing together essential climatic and ecological information about your particular location.

Our first year has been one of spreadsheets, mapping out our seasonal observations and activities, and the One Page Place Assessment concept is a elegant way of compiling climatic data from Second Valley and the surrounding area. We’ve finally completed the first version of a place assessment for our property, with much of the data drawn from Bureau of Meteorology stations nearby (Myponga Reservoir being the furthest). While we have tailored information to our particular location, we hope it will be of use to other landowners in the region. We have also referenced information sources so others can draw on the same resources in exploring their own area.

Book Review: Embracing an arid future in “Growing Food in a Hotter, Drier Land”

Years before there was talk of locavores and 100-mile-diets and omnivore’s dilemmas, I came upon Gary Nabhan’s book Coming Home to Eat, a personal account of his experiences striving to solely eat food produced in his home bioregion of the US-Mexican borderlands in southern Arizona. His observations as renowned desert ecologist and ethno-botanist redefined how I thought about food and sustainability and accompanied me on my own sustainable food explorations for years after.

I get the feeling that his latest book, Growing Food in a Hotter, Drier Land: Lessons from Desert Farmers on Adapting to Climate Uncertainty (Chelsea Green, 2013), may be another companion for us in our adventures on the farm. While Growing Food is as practical as its title suggests, it is permeated by Nabhan’s respect for the insights of cultures deeply connected to the land, and his belief that communities connected to their bioregion are the most resilient in the face of environmental change.

Travels in Inter-Tussock Space: Planning for Woodland

We’ve seeded our last 150 tubes in preparation for planting in a few months time. When the rains come, we’ll have over 1000 plants ready to go. Most are destined for the regeneration areas we’ve fenced around the waterways, but a few others are non-indigenous livestock fodder plants, timber trees and food plants we’ve raised from seed and cuttings to begin developing other zones around the farm.

It’s a Pink Gum Woodland, it just doesn’t know it yet.

Late in 2013, along with a posy of other plant nerds, we attended a workshop with botanist Ann Prescott (author of It’s Blue with Five Petals) to explore ideas behind revegetation for habitat. We walked through remnant woodland in the hills above Yankalilla, and tried to imagine how our farm might have looked 180 years ago. Continue reading →
