Map of the Type 1 ZNIEFF located within the commune.
The inventory ofnatural areas of ecological, faunistic, and floristic interest (Zone naturelle d'intérêt écologique, faunistique et floristique, ZNIEFF) is a French national program aimed at identifying ecologically significant areas to enhance knowledge of natural heritage and aid decision-makers in integrating environmental concerns into land-use planning. One type 1 ZNIEFF[Note 1] is recorded in the commune:[10] the 'Mosson Valley from Grabels to St-Jean-de-Védas', covering approximately 114 hectares (282 acres) across five communes in the department.[11]

^Type 1 ZNIEFF are areas generally of limited size, characterized by the presence of rare or remarkable species, species associations, or habitats that are typical of the regional or national natural heritage.
^An urban unit in France is defined as a commune or a group of communes with a continuous built-up area (no gap greater than 200 meters between two buildings) and a population of at least 2,000 inhabitants. A commune must have more than half of its population within this built-up area to qualify as part of an urban unit.
^In a multi-communal agglomeration, a commune is classified as suburban when it is not the central city; this means its population is less than 50% of the agglomeration’s total population or that of the most populated commune. In the case of the Montpellier urban unit, there is one central city and 21 suburban communes.
^The concept of afunctional area replaced the former concept of anurban area in October 2020, enabling consistent comparisons with otherEuropean Union countries.
