Protected species: project evidence and exceptions
A project affecting protected species needs evidence of the species, habitat, proposed intervention and possible exceptions. Planning permission does not necessarily answer species-protection requirements. France and Switzerland use different statutory and implementing frameworks. The project map organises surveys and alternatives without treating a general environmental approval as a species exemption or promising that mitigation guarantees authorisation.

Which works could affect them?
Describe footprint, timing and possible effects. A building permit does not summarise the species-protection assessment.

Which species or habitats are identified?
Collect surveys, period and observation source. Suspected presence and legally protected status need different evidence.

Which official provision helps explain this situation?
4° La délivrance de dérogations aux interdictions mentionnées aux 1°, 2° et 3° du I et au I bis de l'article L. 411-1, à condition qu'il n'existe pas d'autre solution satisfaisante, pouvant être évaluée par une tierce expertise menée, à la demande de l'autorité compétente, par un organisme extérieur choisi en accord avec elle, aux frais du pétitionnaire, et que la dérogation ne nuise pas au maintien, dans un état de conservation favorable, des populations des espèces concernées dans leur aire de répartition naturelle :
In plain English: France's L411-2 has conservation and enumerated-purpose conditions. Swiss OPN 14/20 technical-intervention branches require location necessity, overriding interest and specified protective duties.
Which works could affect them?
Describe footprint, timing and possible effects. A building permit does not summarise the species-protection assessment.
Which alternatives are documented?
Compare real options and effects. France's L411-2 has a no-satisfactory-alternative condition within its cumulative framework.
Which authority and application are identified?
Keep correspondence and the actual stated route. The worksheet files no exception application and selects no authority from an address.
Which records are still missing from your file?
Indicate which records you have. The result identifies gaps and prepares a complete question for Julie, without requiring an account.

Does planning permission replace a species exception?
No. Separate legal bases and conditions remain relevant. An ordinary project is not automatically entitled to an exception.

Which protective measures are actually supported?
Describe adaptation, protection, restoration or replacement where the applicable rule provides them. Announcing measures alone does not establish all conditions.
What does the species file prepare?
It organises surveys, impacts, alternatives and applications. It performs no ecological assessment and guarantees no permission.
