Designations overlap (a regional park can hold a Natura 2000 site), so the rows don’t add up; the first counts each piece of land once.
100% of Cerny’s land is protected, more than in 95% of compared French towns; the median compared town in Essonne has 0%. A regional nature park is a charter between communes to look after a landscape: farming, building and hunting go on inside it.

That is less than in 63% of compared French towns for footpaths per km², and for woodland more than in 86% of compared French towns. Hiking routes often follow paths and lanes already counted, so the two lengths overlap: don’t add them. Every home in Cerny is within 800 m of a mapped park or wood, as in most French towns.

How to read these numbers
What this data can and can’t tell you
- Protected areas. National-park cores, national parks’ outer areas, regional nature parks, nature reserves and Natura 2000 sites, from INPN. A national park’s core is strictly protected; its outer area and a regional park are charters between communes, not bans. Designations overlap, so the total counts each piece of land once.
- Woodland. Forest and woods as OpenStreetMap maps them, private woods included: woods nobody has mapped are missing, and a mapped wood isn’t necessarily open to walkers.
- Footpaths and hiking routes. Footpaths, bridleways, steps and tracks open on foot, then waymarked hiking routes (GR and others) measured apart. A route often follows a path or lane already counted: the two overlap. Paths nobody has mapped are missing.
- Green space nearby. The share of residents (INSEE’s 200 m grid) within 800 m, as the crow flies, of a mapped park, garden or wood edge. It measures nearness, not a way in. Guadeloupe and French Guiana have no grid: their pages say whether the town center is within 800 m.
- The coast. The straight-line distance from the town center to OpenStreetMap’s coastline, which follows the tide line into estuaries. A commune is on the coast when the coastline crosses its boundary.
- No grade yet. U.S. and UK towns have an Outdoors Grade; French towns don’t yet. Each figure is set beside the median of compared communes (those with an overall grade) in the département and in France, each figure its own median.
