+# Biome And Natural Resource Generation Plan
+
+Agrarian needs Earth-aware tile generation, not hand-authored placeholder maps.
+Every 1 km tile should derive its biome and natural resources from real-world
+environmental signals, then place removable and persistent objects that behave
+like real natural resources.
+
+## Biome Selection Inputs
+
+Each tile should eventually derive biome weights from:
+
+- latitude
+- elevation
+- slope and aspect
+- rainfall
+- seasonal temperature swing
+- ocean proximity
+- prevailing wind
+- ocean currents
+- rain-shadow effects
+- soil type
+- drainage
+- river, lake, wetland, and coast proximity
+- land-use history when available
+
+## Layered Generation
+
+1. Climate engine: produces temperature, rainfall, seasonality, and weather
+   pressure.
+2. Biome generator: assigns weighted macro/regional/local biome blends.
+3. Ecology layer: chooses plant communities, wildlife, disease pressure, soil
+   behavior, and water availability.
+4. Resource layer: places trees, shrubs, grasses, rocks, water bodies, edible
+   plants, fuel, fiber, and old human-made objects.
+5. Human layer: derives agriculture suitability, settlement pressure, trade
+   value, travel difficulty, and cultural/economic implications.
+
+## Biome Output Shape
+
+Avoid hard borders. A tile should produce weighted blends such as:
+
+- `70% coastal scrub`
+- `20% riparian woodland`
+- `10% seasonal marsh`
+
+Those weights drive asset selection, density, color variation, seasonality, and
+resource availability.
+
+## Persistent Natural Resources
+
+Every removable world object should have durable state:
+
+- unique tile-local resource id
+- resource type
+- species or object profile
+- transform
+- growth stage
+- health
+- age
+- quantity remaining
+- removed/depleted timestamp
+- player/planted/natural origin
+- respawn or regrowth policy
+- last simulation timestamp
+
+## Removal And Regrowth Rules
+
+- Trees, shrubs, rocks, puddles, lakes, ruins, shelters, and large props should
+  not silently pop back after removal.
+- Player-removed trees and shrubs stay removed unless replanted or naturally
+  reseeded over realistic in-game time.
+- Stumps, deadwood, brush piles, and disturbed ground should be valid aftermath
+  states rather than instant deletion.
+- Water bodies are removable only through believable terrain/drainage changes,
+  drought, construction, or simulation systems.
+- Edible plants, grasses, brush, and fiber resources can replenish, but only on
+  realistic seasonal timelines and only when biome, weather, grazing, and human
+  use allow it.
+- Player-planted resources use explicit planting/cultivation rules rather than
+  random respawn.
+
+## First Implementation Slice
+
+1. Add tile biome profile data assets or JSON metadata for Ground Zero.
+2. Register asset sets by biome weight: terrain, trees, shrubs, grasses, rocks,
+   water, wildlife, reclaimed props.
+3. Convert placed foliage/resource proxies into persistent resource records.
+4. Add removal state and save/load durability for trees and shrubs first.
+5. Add slow regrowth/reseeding simulation for grasses/shrubs/trees.
+6. Extend to water bodies, edible plants, rocks, and reclaimed objects.
+
+## Investor Relevance
+
+This system should make new tiles feel recognizable without hand-sculpting each
+one. A Pacific coastal tile, a prairie tile, a boreal tile, and a river valley
+tile should choose different assets, resource densities, travel difficulty, and
+survival pressures automatically.
