Nature in the Grasse Prealps

 Nature in the Grasse Prealps

The Grasse Prealps include a large calcareous mountain range north to the city of Grasse, in the French department of Alpes-Maritimes (06). This range of low mountain (maximum elevation 1800 m), located at only 20 km from the mediterranean sea, harbors an exceptional biodiversity. The Parc Naturel Régional des Préalpes d'Azur was created in 2012 to help protecting this outstanding natural heritage.


plateau de Calern

The calcareous plateaus. These vast plateaus are a distinctive feature of the landscape of the Grasse prealps. The plateau de Calern illustrated here is among the finest examples of such a geological formation. It shelters a spectacular diversity of flora and fauna, with rare and endangered species such as the Orsini's viper (Vipera ursinii) and the short-horned grasshopper (Prionotropis hystrix subsp. azami).



The Lapiaz. These eroded dolomitic slabs are typical of the karst. The lapiaz is usually spotted with dolines, formed by collapsed cavities. Because of the large variety of microclimates in the lapiaz, the biodiversity found here is very large, with many rare and very local species.


pond on the plateau de Caussols

The wetlands. Sandwiched between the plateaus are narrow valleys with a clay-rich soil, favouring the presence of wetlands. These fragile areas shelters very specific animal and plant communities, which are often threatened.



The flora of the Maritime Alps is extremely rich, with about 60% of the French species living there. This is also the case in the Grasse Prealps, where many plants occur that are either rare, endemic, or at the limit of their range.

Orchids are fascinating plants, with a stunning diversity of shapes and colors. The Alpes-Maritimes are among the richest French departments in terms of number of orchids species, most of which are found in the Mediterranean zone (see the "Provence-Alpes-Côte d'Azur" section for some examples). However, some species are typical of low mountains:


Spitzel's orchis (Orchis spitzelii)

Spitzel's orchid (Orchis spitzelii). This orchid is identified by its green-tinted perianth, its folded labellum and straight, conical spear. It flowers in low mountains in June, in Scots pine clearings, often on a marly substrate. This species occurs in a rather wide range (from France to Lebanon, up to Sweden in the north and Algeria in the south) with a very scattered distribution. It is everywhere rare and very local. In France, where it is found mainly in the south-east, Orchis spitzelii is fully protected.

lesser purple emperor (Apatura ilia f. clytie)

The lesser purple emperor (Apatura ilia f. clytie). This beautiful butterfly of rather large size is readily identified by its fast and nervous flight, the orange background of the wings (form clytie) and the bright purple iridescent sheen that is only visible under a certain angle of observation. This sheen is due to the tridimensionnal  periodic structure of the wing scales, which turn this butterfly into a flying diffraction grating. The species seems scarce in the Preapls, and is found only along certain streams where its host plants grow (poplars and willows). Butterflies from the Apatura genus are attracted to rotten fruits (wild figs on this photo) and excrements. The lesser purple emperor occurs in most of Europe, Caucasus and Ural up to China.
