Synonyms: Wildflower Turfs, Sedum Blankets, Extensive Green Roof

Green roofs that have not been designed with the purpose of promoting biodiversity (i.e. not a Biodiverse Green Roof) or as part of a park or garden (i.e. not an intensive Green Roof). It will feature drought-tolerant vegetation wildflower turfs and Sedum blankets (which are of low value to biodiversity). It may also include a range of wildflower species.

Assessment Questions:

- Has the green roof clearly not been designed to promote biodiversity?

- Has the green roof clearly not been designed as part of a park or garden?

- Are there Sedum blankets which account for more than 40% of the species on the roof?

- Does it not meet the tests for the Biodiverse Green Roof or the Intensive Green Roof?

If YES, then it is likely Urban - Other green roof

How to get a "moderate" rating

In a management plan aiming to achieve ‘moderate’ condition the plan will show the following:

  • A variety of flower species will be planted, with a focus on attracting insects like bees and butterflies along with other wildlife. Plants will be selected based on how appropriate they are to the size and design of the green roof. The species mix will ensure that there are flowers at all different times of year, providing nectar through the seasons.

  • The seed mix will be mostly native species. Where non-native plant species are present, they will not be harmful to wildlife. The planting mix will exclude invasive non-native species (INNS).

How to get a "good rating"

In addition to the characteristics for moderate condition, to get a ‘good’ condition the plan will show the following:

  • Management will seek to ensure a varied vegetation structure, with at least two physically different habitat elements or vegetation types or heights. The variety will mean that no single vegetation type covers more than 80% of the habitat area.

  • The management regime will ensure that bare ground will not be the most common habitat type.
