Filter Strip
A gently-sloping vegetated strip that intercepts sheet runoff, slows it and removes sediment before it reaches other SuDS features. A simple, low-cost first line of treatment that reads as landscape.
Carbon and evidence
Carbon Sink & Ecosystem Services
A living landscape element — a carbon sink and provider of ecosystem services, not a manufactured product. Its value is measured by sequestration and biodiversity, not embodied carbon, and it must never be netted against a product’s A1–A3.
Carbon Sequestration
Not sequestration-led
The primary value here is biodiversity and/or water function, not carbon storage.
Biodiversity Net Gain
grassed strip is low; a wildflower/species-rich strip scores higher

England requires a 10% Biodiversity Net Gain; distinctiveness is one input to the habitat unit calculation.
Water / SuDS
pre-treatment — intercepts sheet flow and removes sediment

Ecosystem Services
Establishment & Maintenance
grading and seeding only — low upfront carbon cost
