Cascade Order

The Cascade Order is BROWN -> BLUE -> GREEN -> BLACK. It is the recovery sequence behind every EcoIntel diagnosis, and it exists to stop land managers wasting effort on downstream processes when the upstream ones are still broken.

Stage	Represents	What recovers here	Fix priority
BROWN	Bare soil	Ground cover, the foundation	Fix first: nothing downstream recovers over bare soil
BLUE	Water cycle	Infiltration, retention, cycling	Once cover holds, restore the hydrology
GREEN	Living systems	Functional diversity, soil fauna, stable community	Once water cycles, build the biology
BLACK	Soil carbon	Organic matter, the slow accumulation	Follows as a consequence once the first three come right

Each stage depends on the one before it:

• BROWN: bare soil. The most fundamental fix. Soil that is exposed to sun, wind and rain is leaking energy, water and mineral capacity all at once. There is no point planting diverse species into a field that still seals on impact; nothing else recovers until ground cover is restored.
• BLUE: the water cycle. Once the soil is covered, water can begin to infiltrate, hold and cycle. Until the water cycle works, downstream processes cannot.
• GREEN: living systems and community dynamics. With cover and water working, biological diversity can develop: functional plant groups, soil fauna, the relationships that make an ecosystem stable.
• BLACK: soil organic matter and carbon. The long tail. Carbon accumulates as the consequence of the other three working well. It is the slowest indicator to move, and the one that fails most slowly too.

The cascade matters because each stage depends on the previous. EcoIntel diagnoses where each parcel sits on the cascade and recommends the upstream fix first. A field with low Mineral Cycle Index (MCI) and persistent bare soil gets a “fix cover before anything else” prescription; a field with healthy cover but degraded water cycle gets a hydrological intervention before species-diversity work; and so on.
