Questione giuridica chiave
Whether the municipal/cantonal hedge protection rested on sufficient legal basis or should have been assessed under federal nature protection law
Decisione estratta
The lower court applied federal law too narrowly; cantonal and municipal law provided a valid, broader legal basis for general hedge protection.
Motivazione estratta
The cantonal ordinance and the municipal zoning code allowed a general hedge protection regime exceeding the federal minimum; the decisive problem was not the legal basis but the missing case-specific assessment of biotope quality.
