Scientific knowledge
Four actions will be carried out in order to improve the scientific knowledge of the species :
• Telemetric monitoring in the Basses Vallées Angevines and Moyenne Vallée de l’Oise to clarify the use of different habitats by the Corncrake before and after mowing ;
• Studying the development and attractiveness of the ground vegetation: the objective is to assess the impact of agricultural management on vegetal composition, and to study its attractiveness for the Corncrake.
• Monitoring and analysis of the chronology of mowing on the land under and without contracts (agri-environmental measures) for measuring changes in the timing of mowing and adapt future agri-environmental measures.
• Annual monitoring of the breeding population to identify the relevance and effectiveness in the short and long term actions proposed in the programme. This monitoring will enable to study the area favourable to the corncrake and the evolution of the singing Corncrakes.

Radio-tracking monitoring
19 February 2014, by Sophie Duhautois
**Sites involved in the action
The Basses Vallées Angevines and the Moyenne Vallée de l’Oise
**Objective Improving the protection of broods and individuals saved from mowing machines.
**Description
Studying movements and suitability of different habitats for the Corncrake during the breeding season (location of singing males and brood) and during mowing.
**Methodology
The Corncrake is a very secretive and nocturnal species, thus telemetry is the preferred method.
Radiotracking (...)

Study of the evolution and attractiveness of the ground vegetation
19 February 2014, by Julien Lusson
**Sites involved in the action
The Basses Vallées Angevines, Moyenne vallée de la Charente and the Moyenne vallée de l’Oise.
**Objective
Identifying and providing practical improvements for grassland management practices, essential for maintaining suitable ground vegetation for the Corncrake and improving the conservation status of the species.
**Description
The initial methodology is not the same on the Angevins, Picards and Charentais sites. It will therefore highlight the common and (...)

Monitoring the mowing
19 February 2014, by Sophie Duhautois
**Sites involved in the action
The Basses Vallée Angevines, Moyenne Vallée de la Charente and the Moyenne Vallée de l’Oise
**Objective
Assessing the impact of conservation measures and communication about chronology of mowing
**Description
The conservation management measures for the Corncrake aim at delaying mowing dates and adapt the best mowing practices. Dates and times mowing vary from one year to another on a given site, mainly due to climatic conditions. However, there are little (...)

Breeding monitoring
19 February 2014, by Sophie Duhautois
**Sites involved in the action
The Basses Vallées Angevines, Vallée de la Loire, Moyenne Vallée de la Charente and Moyenne Vallée de l’Oise **Objective
Assessing the impact of conservation measures on the Corncrake population **Description
The monitoring focuses on:
• the annual assessment of Corncrake populations on sites chosen for bird counts;
• monitoring and research mowing on young birds to assess survival rates and productivity, and to compare the effectiveness of the proposed measures (...)
