A green setting overlooking the lake
This forest walk takes you through very contrasting natural environments. By crossing Roc de Chère you’ll pass from alpine environments to Mediterranean ecosystems. A fauna and flora of opposite affinities find refuge on this same rocky outcrop which overlooks the lake of Annecy.

Flora

A young forest

The forest that you can admire is rather young: it is just a century old. Until the beginning of the 20th century, the Roc de Chère consisted of open landscapes, mostly cultivated (cereals, vines, pastures, mowing grasslands). It was only after the 1st World War, with the desertification of rural environments leading to the disuse of agricultural land, that the massif was gradually turned again into forest. Farmers, shepherds and woodcutters are now replaced by walkers, geologists, botanists: other uses, other approches of landscapes and natural environments...

Fauna

The Green Lizard

Sometimes fleeing at the very last moment, the Green Lizard is quite impressive. It can measure up to 40 cm, with two-thirds of its length on the tail. Its bright green yellow dotted body can’t go unnoticed! In the spring, the male also sports an obvious blue throat. Attracted by hot and dry semi-open environments, the Green Lizard appreciates the Mediterranean forest and the rocky outcrops of Roc de Chère where it visually part of the landscape, difficult to notice between rocks and vegetation.

Fauna

The Fire Salamander

Forest and ponds? What more could you dream of for lady salamander, the species the most depending on forest among the amphibians living at Roc de Chère!
It only uses ponds to give birth to its larvae, equipped with gills, like tadpoles. A poor swimmer, it quickly returns to the forest, leaving her young to lead their first phase of aquatic life. This nocturnal animal has smooth, black skin interrupted on its back by a yellow, occasionally orange, pattern of dots and/or lines. Each individual has a unique pattern!

The mediterranean forest

You can’t really say that it’s a coincidence that the vegetation reminds you of the forests of the Mediterranean hinterland (Boxwood and Oak). The southern orientation of the hillside has a great influence on the microclimate and the vegetation. In this location, the solar radiation is more important since reflected on the waters of the lake. Moreover, the position of the Roc de Chère on the lake stops the northern winds. For all these reasons, you can find species adapted to warm climate, such as Commun Wild Madder and Montpellier maple, attesting this microclimate.

Common or Bell Heather

Do you recognize these two different species? Hint: Common Heather has distinct petals while Bell Heather has bell-shaped flowers and its leaves look like small Cedar twigs while those of Bell Heather form needles.

Common Heather is often confused with other species of heather such as Bell Heather. This confusion comes from the exploitation of heather soil, called “black gold”, a very good fertilizer used by gardeners. Indeed, Common Heather is able to grow on acid soils and even directly on the rock. The dead plant parts pile up and decompose and form black humus. Asters CEN74, manager of the nature reserve, is carrying out actions in order to preserve the Common Heather, which is gradually being colonized by ferns.

Forest ponds: an essential environment

Did you know this? Wetlands are the third richest ecosystem in terms of biodiversity in the world. They have the ecological function of storing rainwater, like a sponge, filtering it and storing carbon.
Forest ponds, prime wetlands, are sources of drinking water for many mammals (deer, bats, foxes).
They are also ideal breeding sites for many insects (dragonflies) and amphibians (frogs, newts).

The Common Wild Madder

The Wild Madder is closely related to of the Dyer’s Madder, which was cultivated in the past to produce a red dye. Very common on the Mediterranean shores, the Wild Madder has not known an industrial use and yet its root also gives a red-orange dye. Did you know it? In a botanical perspective, Wild Madder is also related to coffee!

Geology

Lime- and sandstone soil

The bedrock of Roc de Chère is composed as well by limestone on the right side of the forest (Talloires) as by sandstone at the edge of the young forest (Menthon-Saint-Bernard).

Roc de Chère is located on a very original fault, between two geological layers which give this specific shape the landscape. The Green Lizard and Wild Madder prefer these draining and hot limestone environments, while Common Heather and ponds are found on sandstone, an acid and impermeable soil.

The secrets of the marshland

This marsh is a remnant of a time when glaciers still covered the valley. These wetlands, becoming increasingly rare, are home to remarkable and sometimes threatened flora and fauna. Frogs and lizards hunt the graceful dragonflies flying between the irises. It is mown every year by the golf course holders in order to prevent drying out and natural closing of the ecosystem by trees.
