Recipe library
One map supports far more statements about a landscape than are usually drawn from it. Each recipe on the right answers one question, such as how isolated a patch is, where a corridor runs or how much core a road destroys, in a few steps of mosaik. They are a selection, not the limit, and so are the inputs: the same operations combine into many more recipes, and work on any other map you have. Even so, they show what the example landscape on the left holds, and what your own map would hold too. Hover over a recipe to see its answer on the map, click a spot to see which recipes have something to say about it, and tick the data you have to see which recipes are open to you.

How much?
How is it arranged?
- Connectivity through the land How hard it is to get from each patch of forest to the next, crossing the land as it is.
- Core The part of each patch far enough from its edge not to be affected by what lies outside.
- Corridors Narrow strips of forest that join two cores, told apart from dead ends.
- Critical places The narrow parts of the forest where a small clearing would split a patch in two.
- Ecotones The zone of transition between the forest and the land next to it.
- Holes in patches The land a patch encloses, numbered and labelled with the patch around it.
- Indentations Bays cut into a patch from its edge, the shape a clear-cut leaves, found by closing the patch.
- Interrupted corridors Patches separated only by a narrow break, such as a road or a river.
- Islets Patches of forest too small or too narrow to hold any core.
- Isolation The distance from each patch to its nearest neighbour.
- Linear elements Hedgerows and corridors told apart from compact blocks of forest.
- Parallel structures Where one linear structure keeps a constant distance to another, like a road beside a river.
- The structure of a protected area How much of a declared area is forest, how much of that is core, and into how many patches it falls.
What state is it in?
- Condition against a declared reference How far each forest patch is from a reference state, between a reference level and a collapse level.
- Sharp and gradual edges Forest edges with a mantle of lower trees told apart from those where tall trees stand right at the edge.
- The edge-depth curve How far the effect of a forest edge reaches into the forest.
What acts on it?
What changed?
- Conversion of natural ecosystems Natural land at an earlier date that is no longer natural today.
- Core lost against area lost How much undisturbed forest interior was lost since an earlier date, compared with the forest cleared.
- Old and new edges Edges cut recently, which have not yet grown the lower mantle of old ones.
