The pools once had many practical uses to meet human needs: domestic uses (water reserve, fish tank for food, laundry), agricultural (drinking for animals, curling of flax and hemp), handicrafts (vanry) but also for leisure activities (bathing, fishing, etc.).The evolution of agricultural practices (consolidation, drainage, intensification) and the arrival of drinking water into households have led to a gradual abandonment of the ponds and many of them have been filled or filled naturally. Since 1950, between 30 and 50 % of the pools have disappeared in France. The remaining ponds are mostly abandoned. In Normandy, it is estimated that 40 % of pools are threatened in the short term.Today, ponds are once again recognised as special habitats with multiple interests. From an ecological point of view, they are real reservoirs of biodiversity in which many animal and plant species linked to the presence of water can develop and reproduce. As such, the pools are a great educational tool for the education of schools and the general public on the protection of nature. These habitats are also an essential link in the blue frame, especially in the areas of plateaus where they are often the only component of the blue frame. Ponds also play a hydraulic role in regulating and storing runoff water. They also contribute to the purification of water and the preservation of hydrosystems through the sequestration of sediments, pollutants (pesticides, nitrates, etc.) and their degradation through microbial processes. They have an interest in livestock farming since they are also used for the watering of livestock in grazed grasslands. Moreover, these environments constitute a strong element of diversification of landscapes, particularly in areas of intensive agriculture, and a space for relaxation and discovery for the public. Awareness of the need to protect these areas has emerged among several Norman actors (intercommunalities, local associations, watershed unions) for several years. Many actions in favour of the ponds thus emerge, but in a more or less concerted way and with objectives specific to each structure and which sometimes do not necessarily lead to an improvement in the ecological quality of the ponds. On the other hand, other territories do not benefit from restoration and protection actions in favour of these communities.The need to coordinate actions, to mobilise all actors in the territory, to improve the consideration of the biodiversity of the pools but also to educate the general public and schools required the drawing up and implementation of a plan of regional scope: the Regional Action Programme for the Ponds of Normandy.This programme whose aim is to halt the process of degradation and disappearance of the ponds in the region has been initiated and is carried by the Conservatoires d’espaces naturelles de Normandie.This request for financial assistance concerns only the Conservatoire d’espaces Normandie Seine for the regional animation of the PRAM and its declination on the territory in the departments of Eure and Seine-Maritime.On the other hand, the project described in this technical memoir (axis of work, objectives and operations) is the result of a concerted work and common to the departments of the Normandy Conservatory. For territorialised actions, each Conservatory is responsible for implementing them within its jurisdiction. For Normandy-wide actions, the Conservatoires work together in full coherence and complementarity.
