The Agoraie Reserve is closed to the public, and therefore the lake cannot be visited except for study or few educational visits, which have to be booked on the Parco dell’Aveto website (

The Biogenic and Oriented Nature Reserve of Agoraie is situated in the Aveto Regional Park, in the proximity of municipality of Bosco Fontana. The Reserve is divided in two distinct portions: The Agoraie di Sopra and Moggetto. Both portions are closed to the public due to the extreme fragility of the ecosystem. The area has glacial origin for the expansion of the glacier from the Mountain Aiona, which expanded for more than 4.5 km and formed morenic deposits at the boundaries of steep slopes. A peculiar characteristic is the presence of flooded areas and glacial lake formations containing plant and animal species usually located at higher altitudes.

Among the peculiar plant species, there are Lycopodiella inundata and Drosera rotundifolia.

Lycopodiella inundata, also called Lepidotis inundata, or flooded Lycopodium, is a perennial, evergreen species of the Lycopodiaceae family. In Italy the species is rather rare and considered Vulnerable.

The diffusion is circumboreal, therefore in the cold areas of Europe, Asia and North America, at altitudes up to 2,000 m above sea level and this is is the southern station where it is present.

The classic habitat of Lycopodiella inundata are acid peat bogs, humid and sandy places (depressive banks of lakes), marshy areas.

Lycopodiella inundata is a perennial plant with a creeping habit. It has fertile stems bearing spores and sterile stems bearing only leaves. The sterile stem branches horizontally on the ground, is 5 to 25 cm long and has a thickness of 0.5 to 1 cm including the leaves. The leaves are light green, needle-shaped, arranged in a spiral or alternate, 3 to 8 mm long and no more than 1 mm thick. There are generally 1 to 2 fertile stems growing vertically without branching. They have a height of 4 to 15 cm including the conoidal structure at the tip (strobilus) which contains the spores, and are approximately 3 - 4 mm thick, including the leaves. The cone at the top is a maximum of 5 cm long and 8-10 mm thick. The numerous sporophylls on the cone are dense and enlarged at the base (which contains the globose sporangium), but otherwise resemble sterile leaves, and are lanceolate in shape with a sharp tip. The spores have a diameter of 40 to 46 µm and mature from August to October.

The Drosera rotundifolia has a distribution limited to the Northern Hemisphere; in Italy it was once very common, but today it is very rare and it is possible to encounter it occasionally along the Alpine and pre-Alpine arcs. It is an herbaceous plant 10–20 cm tall, with obovate leaves and a long petiole, arranged in a basal rosette, equipped with long tentacles with purple hairs that secrete drops of a viscous liquid, in which small insects remain trapped. The tentacles fold back onto the prey after capture. It blooms from April to September with small white flowers.
