A Biodiversity Oasis with 1,500 nectar-producing plants in Sardinia produces the organic honey that becomes the sole sweetener of Mielissa, the Tre Marie croissant. From habitat regeneration to product supply chain, every phase is monitored with scientific data.
The food industry promotes sustainability but rarely proves a direct link between environmental action and the final product. Honey depends on ecosystem health: its quality requires diversified nectar habitats, healthy bee colonies and biodiversity. Producing organic honey means regenerating an ecosystem, not just sourcing a raw material.
For Tre Marie, turning this into a real product requires a project spanning planting, scientific monitoring and traceability of honey from the Oasis to the croissant.
Sammontana wanted to create Mielissa, a Tre Marie croissant sweetened with traceable organic honey linked to biodiversity regeneration.
A project was needed to create the conditions for honey production, monitor regenerative impact via site-control comparison and ensure Mielissa's honey came from the Oasis.
XNatura built the Sammontana Biodiversity Oasis in Sardinia: 1,500 nectar-producing trees of 11 species to maximise nectar and pollen output. The Oasis organic honey is the sole sweetener of Tre Marie Mielissa croissant.



A project that starts from the regeneration of an ecosystem and reaches the finished product: planting, scientific monitoring and a traceable organic honey supply chain.
Satellite analysis mapped the intervention area and the surrounding territory as a control area, producing the biodiversity indices baseline: MSA Land Use, nectar-producing potential, relative pollinator abundance. These data defined the starting point for measuring the impact of regeneration.
1,500 nectar-producing trees of 11 species were planted in the Oasis in Sardinia. The species were selected to ensure staggered flowering throughout the year and maximise nectar and pollen production, creating the conditions for the production of the organic honey that becomes the sole sweetener of Mielissa.
Satellite and sensor data were integrated to compare the ecological conditions of the estate with the control area. The site-control comparison quantifies the difference in terms of MSA, nectar-producing potential, pollinator diversity and soil cover, documenting the regenerative impact of the Oasis with scientific evidence.
The data flow into the XNatura Environmental Platform, where Sammontana monitors the evolution of the Oasis. The site has already reached four of the five platform regeneration objectives. The organic honey produced in the Oasis is harvested, certified and used as the sole sweetener of Mielissa, the Tre Marie croissant: a product whose supply chain starts from the regeneration of an ecosystem and reaches the consumer with scientific data to support it.
The Oasis records a delta of +31 on the MSA Land Use index compared to the control area, confirming that the planting intervention has generated a significant and measurable improvement in biodiversity. The delta of +3 in relative pollinator abundance indicates that the Oasis is attracting and sustaining a richer pollinator community compared to the surrounding territory, an essential condition for the production of the organic honey used in Mielissa.
The Oasis's nectar-producing potential exceeds the control by +94 points, a direct result of the 1,500 nectar-producing plants of 11 species with staggered flowering. The Oasis has reached four of the five platform regeneration objectives: Match Neighbour, Match Benchmark, Regenerate 30% and Half Earth. The honey produced by bees foraging on the Oasis's blooms is the same organic honey that sweetens Mielissa: a croissant whose supply chain starts from the regeneration of a scientifically monitored ecosystem.
