Essential Oil Farming and Biodiversity: A Complex Relationship
Monoculture farming of essential oil crops can reduce biodiversity. Here is how responsible producers manage this tension.
Essential oil crops are often grown in monoculture, which means large areas planted with a single species. Monoculture farming simplifies harvesting and processing but can reduce local biodiversity, deplete soil nutrients, and increase vulnerability to pests and disease. Understanding this trade-off is important for evaluating the sustainability of essential oil sourcing.
The monoculture problem
A field planted entirely with lavender or tea tree supports far fewer species of insects, birds, and soil organisms than a diverse natural landscape. The loss of habitat diversity reduces the resilience of the local ecosystem and can affect pollinator populations, which are important for the surrounding agricultural land.
Agroforestry and polyculture
Some essential oil producers are experimenting with agroforestry approaches, where essential oil crops are grown alongside trees and other plants. This increases habitat diversity, improves soil health, and can reduce the need for synthetic inputs. The trade-off is increased complexity in harvesting and processing.
Wild harvesting
Some essential oils are produced from wild-harvested plant material. Wild harvesting can support local ecosystems if done sustainably, but it can also deplete wild populations if demand exceeds the regeneration rate. Frankincense is a well-documented example of a wild-harvested crop where demand has outpaced sustainable yield.
Our approach
We prefer suppliers who can demonstrate that their farming practices include habitat management, whether through hedgerows, buffer zones, or polyculture approaches. We also prefer cultivated over wild-harvested sources for species where wild populations are under pressure.
