I don't see anything obviously wrong with the expression. I would suggest adding some Console statements to the expression just to check the output of it.

var znieff1 = FeatureSetByName($datastore, 'ZNIEFF Type 1') Console(Count(znieff1)) var xs = Intersects(znieff1, $feature) Console(Count(xs), 'features in intersection') var interznieff = First() Console('area of feature:', Area(interznieff)) var interarea = Intersection(interznieff, $feature) return Area(interarea)

The Area function can depend on the layer's coordinate system, too. Try AreaGeodetic(interarea), does that give you anything different?
