Hedgerows & biodiversity corridors
Ecological infrastructure that hosts the vineyard’s beneficials.
Ecological infrastructure is the backbone of functional biodiversity. Hedges, copses, dry-stone walls, flower strips and corridors give permanent shelter, food and breeding sites to beneficials and pollinators.
Unlike the cover crop, which is seasonal, these structures are perennial — they sustain populations of beneficials that colonise the vineyard and help regulate pests, while storing carbon in woody biomass and reducing erosion and wind.
Effort
Medium to establish; low to maintain.
Cost
Medium — initial plants and labour.
Time to result
2–5 seasons for the structures to mature.

Biodiversity & ecosystem
Perennial, diverse habitat is the main reservoir of beneficials, pollinators and wildlife — the engine of functional biodiversity.
Time horizon: 2–4 seasons
What to measure for this pairing
Input reduction & vine resilience
Stable beneficial populations reduce the need for insecticides by regulating pests naturally.
Time horizon: 2–4 seasons
What to measure for this pairing
Carbon sequestration & climate
The perennial woody biomass of hedges locks carbon above and below ground durably, unlike seasonal cover.
Time horizon: 3–7 seasons
What to measure for this pairing
How it works
Perennial habitat supplies nectar, alternative prey and overwintering refuge, keeping beneficial populations ready to colonise the vineyard in spring.
How to implement
- 1Map margins, banks and unproductive corners to plant.
- 2Choose native species with staggered flowering.
- 3Plant hedges and sow flower strips linking habitat patches.
- 4Record area and linear metres as ecological infrastructure.
What to measure
Frequently asked
Don’t hedges also host pests?
Diversity tends to favour beneficials over pests, because it creates a more balanced food web. Choosing the right species reinforces that effect.
How much area should I dedicate?
Many sustainability schemes target 5% or more of the area in ecological infrastructure. Unproductive margins and corners are the natural starting point.
