Shut up and listen
Every site broadcasts its condition. The first job in any restoration project is to read the signal.
Walk the land at different hours. In dry weather, in rain. Carry a notebook. Leave the planting plan at home.
The quality of your observations decides whether the restoration thrives or fights conditions you missed.
Read the landform
Stand at the highest point. Read the shape.
Aspect. South-facing slopes in the northern hemisphere bake harder, dry faster, and grow a different palette than north-facing slopes. Mark which is which.
Gradient. Steepness sets how fast water moves and how easily soil leaves. A 5% slope is gentle. Above 15% you are in erosion territory.
Position. Water, nutrients, and seeds run downhill. Valleys and saddles hold deeper soil. Ridges and upper slopes are thin and exposed.
Watch the water
Visit during heavy rain. Not after. During.
Sketch where water sheets across the surface, where it cuts rills, where it pools, where it sinks in. One afternoon in the rain teaches more than a week on topo maps.
Pooling zones are your most productive ground. Scour zones are your urgent erosion control priority.
Tools that cost almost nothing
A clinometer app on your phone reads slope to the degree. Useful for siting swales and check dams.
An A-frame level, two sticks and a plumb line, walks contour across a slope. Stake the line and you have the spine of every earthwork.
For soil: collect samples from five points across the site, at 15 cm and 30 cm depth. Send for pH, organic matter, NPK, and texture.
Then do the hand tests. Squeeze a moist handful. If it ribbons between thumb and finger, it has clay. If it crumbles, it is sandy. Smell it. Healthy soil smells like rain on warm earth. That is geosmin, made by actinomycetes. Sour or metallic smells mean anaerobic ground or contamination.
Read the past
Old aerial photos rewrite what you think you see.
A paddock that was forest in 1970 still holds a seed bank and old root channels. A field cropped continuously for a century has burned through its biological capital and needs heavier intervention.
Look for ghost hedgerows, former creeks, and vegetation lines. They show what the land carried before, and what it can carry again.
The weeds are talking
Plants colonise ground that suits them. Their presence is diagnostic.
- Dock and sorrel: acidic soil
- Nettles: high nitrogen, often from old manure or rotted matter
- Horsetail: wet, compacted, poorly drained
- Plantain: compaction. A lawn full of plantain is a pressed lawn.
- Clover on bare ground: nitrogen deficient. Legumes fix their own and outcompete grasses where soil N is low.
- Mosses on bare soil: high moisture, low disturbance
Existing trees carry the strongest signal. Willows mark seasonal water. Birch, alder, and acacia mean disturbed early succession, the work of pioneer species.
Mature native trees on site are gold. They prove the species grows there. They seed the next generation and feed wildlife corridors. Protect them absolutely. One mature tree outweighs a hundred nursery seedlings.
Build the site plan
Synthesise. Not a planting plan yet. A map of what you know.
Slope. Aspect. Water flow. Soil zones. Existing vegetation. Access. Boundaries. Constraints.
Then divide the site into character zones. Upper slope: dry, thin, exposed. Lower slope: deeper, wetter, remnant trees. Each zone gets its own approach.
Layer the data. Contours guide earthworks. Water flow targets erosion control. Soil tests flag amendments. Indicator plants show what is already moving and what is stuck. Old photos hint at the target ecosystem.
What you do not know
A good plan documents its own gaps.
Could not visit during the wet season? Go back. Soil chemistry came back odd? Get a second read. Unsure of a tree species? Get it keyed.
Restoration is iterative. The site plan is a living document, refined as you learn. Masanobu Fukuoka watched his land for decades before settling his methods. That patience is the foundation.
