Protected species recorded within reach
Observations recorded in the ten years before the flood, some known only to within a few kilometres, up to 10 km, when their published position is blurred or given by grid square. They tell which species were reported there, not what became of each animal.

11 protected animal species among them
6 Birds
2 Amphibians
2 Insects
1 Reptiles
In the water's path
Establishments registered today within reach of the flood, at their declared address or at the point Géorisques gives. They were not necessarily there on the day of the flood, and the dataset does not say whether they were flooded. An ICPE-classified farm can also be in the SIRENE register: these counts do not add up.
No ICPE-classified livestock farm located within the flood's reach
Géorisques · ICPE1 livestock business in the SIRENE register based within the flood's reach
SIRENE register · InseeNo veterinary practice based within the flood's reach
SIRENE register · InseeNo animal protection association based within the flood's reach
National register of associationsNo wildlife association based within the flood's reach
National register of associations
The one livestock business in the SIRENE register: 1 cattle, sheep, goat or pig farm.
A wildlife association is an association whose declared purpose in the national register of associations is the preservation of wildlife: the register does not say whether it runs an authorised care centre. Associations are counted at their declared address: an association or a care centre based outside the area can work across all of it.
Protected areas within reach
Area of each site within reach of the flood, and the share of the site it represents. Natura 2000 and regulatory protection first, then the ZNIEFF.
- Gave de PauNatura 2000, Habitats Directive84 ha within reach1.0% of the site
- Château d'Orthez et bords du gaveNatura 2000, Habitats Directive75 ha within reach1.2% of the site

- Réseau hydrographique du Gave d'Oloron et de ses affluentsZNIEFF type II (inventoried natural area)126 ha within reach1.8% of the site
A ZNIEFF is a wildlife inventory, with no regulatory protection.
