Biodiversity management

Managing biodiversity in a modern citrus farm is an essential component of sustainability and regenerative agriculture. It goes beyond simply protecting; it’s about actively integrating and fostering wildlife and ecosystems within and around farms to improve productivity and reduce reliance on chemical inputs.

For a company like Evyan, biodiversity becomes an agronomic tool and a differentiating factor in the market.

1. The Central Objective: Biological Control by Conservation

The cornerstone of biodiversity management in citrus is Conservation Biological Control. This involves creating a suitable habitat on the farm to attract, feed, and shelter the natural enemies (beneficial fauna) of citrus pests.

Common PestEncouraged Natural Enemies
California Red ScaleAphytis melinus (Parasitoid)
CotonetAnagyrus pseudococci (Parasitoide) y Cryptolaemus montrouzieri (Depredador)
Red Spider MitePredatory Mites (Neoseiulus californicus)

Key Practices to Promote Beneficial Wildlife:

  • Hedges and Biological Corridors: Plant plant species that are not hosts to citrus pests along the edges of the property or on the verges of roads. These plants serve as shelter and a source of nectar (an alternative food source) for natural enemies year-round, even when the pest population is low.
  • Vegetation Cover Management: Avoid tilling the soil and the indiscriminate use of herbicides in the streets. Vegetation cover provides a microclimate and shelter for predatory insects (such as ground beetles).
  • Reduction of Chemical Agents: The most effective measure. The use of broad-spectrum insecticides is the main culprit in the destruction of beneficial insects. The company should transition to Integrated Pest Management (IPM) programs, using low-impact products or biopesticides to protect beneficial insects.

2. Habitat and Landscape Conservation

Biodiversity management in citrus farming extends beyond the fruit tree, encompassing the entire farm environment.

  • Non-Productive Areas: Maintain uncultivated areas, such as slopes, ditch banks, or irrigation ponds. Regenerate vegetation in these areas, creating a habitat for local flora and fauna.
  • Water Resources Management: Irrigation ponds and canals not only fulfill a water function, but, if managed ecologically, they become refuges for amphibians and birds, acting as wildlife hotspots.
  • Monitoring and Evaluation: Conduct biodiversity inventories (flora and fauna indices) to measure the impact of actions and establish continuous improvement goals.

3. Responsibility and Certification

Biodiversity management is not just an internal practice; it is a market requirement validated by certifications.

Standard/NormRelevance to Biodiversity
GLOBALG.A.P.It contains a mandatory module on the Environment that includes managing the impact on biodiversity.
GLOBALG.A.P. + Add-on (GRASP)While it focuses on social aspects, its approach to overall sustainability promotes good agricultural management that benefits the ecosystem.
Organic Agriculture (QUE)It is the most demanding standard in biodiversity conservation, prohibiting most synthetic chemicals that affect beneficial fauna.

Biodiversity management at Evyan means adopting a model where nature works for the company, resulting in high-quality harvests with less environmental impact and reduced pest control costs. It is a cornerstone of sustainable competitiveness.
