Biodiversity Green Roof
In our increasingly urbanised world, cities have lost much of their green space and natural vegetation, leading to biodiversity loss. The absence of plants in urban areas has reduced habitats and food sources for our precious pollinators.
As a solution to encourage urban biodiversity, Junglefy have developed an industry-first innovation to attract insects and animals back into cities. The Junglefy Biodiversity Green Roof features pollinator mounds and ‘hotels’ that provide habitats for pollinators. The mounds are constructed with rammed loam and old logs and branches have been drilled with holes to provide opportunities for ground-nesting pollinators. The mounds and logs are placed among plants that are known to attract pollinators, including the native reed bees and blue banded bees.
The plants used in the Biodiversity Green Roof are mix of natives and exotics that provide both pollen and nectar. This variation is important as pollinating insects require nectar for fast complex carbohydrates, used for energy and pollen which is used to store for their young and to convert into honey. The mix of exotics and natives also provide a year-round food source, especially over winter months when food sources (flowers) are usually limited.
Pollinators like to forage for food in bright, warm and sunny positions, so providing a dense food source on the rooftop will ensure foraging is easier. The sites of the pollinator mounds have been placed in areas where the wind is less likely to affect pollinators.
Junglefy gathered research and conducted testing to gain expertise on pollinator habitats. Having created dozens of green roofs, Junglefy constructed the foundation of the green roof with appropriate irrigation, drainage and soil. Our team of horticulturalists, planted thousands of plants throughout the roof top and carefully built the pollinator mounds. Logs and branches were sourced and drilled with holes and placed on and near the mounds.
Our maintenance team visit regularly to carry out maintenance where required, check irrigation and systems, and inspect the nests for evidence of pollinator activity.
Junglefy developed the concept of incorporating habitats within living infrastructure as a response to the threat facing pollinators from declining biodiversity and pesticide use. We conducted extensive research to develop a deep understanding of the plants, conditions and behaviour of pollinators in order to provide the ideal habitat conditions.
Junglefy tested various soil and materials to develop the perfect composition for durable mounds that provide the optimum nesting opportunity. To complement the mounds, reclaimed logs of various timbers are distributed throughout the plants to ensure the nests are close to abundant food.
