| 1 | Alpine High Mountains | Pyrenean ridge, glacial cirques, above 2000 m | Ridge → glacial cirque → alpine meadow → scree slopes |
| 2 | Subalpine Forest Zones | Irati, Belagua – conifers and beech at high altitudes | Mountain slope → beech/fir forest → subalpine pasture |
| 3 | Karstic Limestone Plateaus | Urbasa, Larraun – sinkholes, bare rock | Limestone plateau → dolines → dry meadows |
| 4 | Deep Mid-Mountain Valleys | Baztan, Roncal – narrow, forested | Ridge → steep slopes → riparian corridor → village |
| 5 | Atlantic Forest Valleys | Quinto Real, Bidasoa – humid and closed | Valley floor → dense mixed forest → pasture edges |
| 6 | Mediterranean Hill Ranges | Estella, Olite – olive groves, dry scrub | Rounded hills → olive groves → dry shrublands |
| 7 | Fertile Floodplains | Pamplona basin, Arga valley – fertile and flat | River → floodplain → fields → village core |
| 8 | Terraced Vineyards | Valdizarbe – south-facing slopes with vineyards | Slope → vineyard terraces → dry wall paths |
| 9 | Erosion Plateaus | Zona Media – clay, gullies, wind-sculpted | Flat top → gullies → isolated crop fields |
| 10 | Volcanic Relics | Ablitas area – tertiary cones | Volcanic cone → gravel plains → sparse vegetation |
| 11 | Semi-desert | Bardenas Reales – steppe, bare erosive land | Badlands → mesas → dry riverbeds → open plain |
| 12 | Irrigated River Plains | Ribera Alta – productive Ebro tributaries | River → irrigation channel → fields → farmhouses |
| 13 | Salt Basins and Lagoons | Salinas de Oro, Pitillas – saline sinks | Lagoon → salt crust → halophyte vegetation |
| 14 | Canyon Landscapes | Foz de Lumbier – vertical gorges, bird habitats | Plateau edge → gorge entrance → river corridor |
| 15 | Transitional Forest Zones | Aoiz, Sangüesa – open deciduous forests | Hills → oak forest patches → clearings |
| 16 | Extensive Agricultural Plains | Ribera Alta – large-scale crops | Flat plain → large fields → irrigation grid |
