At the beginning : Heavy feeding stations
1981 – 2001: 4 official « heavy » feeding sites ( very close to colonies) carrions collected at 62 local farms Food highly predictable in time and space Intense intra specific competition

FARM FEEDING STATIONS

In the 90’s farmers are demanding for individual feeding stations
Acknowledgement of the vulture’s role as natural collaborators in the management of carcasses

How do farm feeding stations work ?
– Farmer has an official authorization – Farmer manages the disposal his own way – No more than 300 kg at the same time – Taxes reduction of 60 % – Farmer record on a file, sent every year to administration – Farmer clean the “placette” by burning bones and remaining – Reduce sanitary risks – Reduce CO2 emissions and transport costs

Situation of food supply for griffon vultures in Grands Causses
– 152 placettes in Grands Causses
– 2 HFP, 21 farmers collected – ~ 20 tons collected of carrions – Allows us to capture, read ring codes, communicate and monitor…
represents less tha1% of the total tonnage of quartering service in France

How a farmer can apply for a farm feeding station ?
– The farmer makes a demand as volunteer – LPO GC works with the farmer on a technical level to prepare the application file – The vet administration check the application details – The Vulture & Livestock comity validate the beginning of construction – The farmer build the station himself – The administration and LPO visit the station and validate or ask for more work – Local “Préfet” sign the “décret” of authorisation for the use of the station – The farmer sign a management convention

What are the needs for Griffon vultures ?
170 kg of food per year
(with ~50 kg of consumable flesh ~75 %)
griffon vulture eat the flesh of 3 to 4 carrions of sheep per year (75 % of carrions)
Griffon Vulture
Sardinia
30th June 2016
What needs for the colony?
– So 1058 reproducing adult griffon vultures
1400 and 1700 birds
290 tons per year
This represents 4700 to 5800 carrions per year (used at 75 % )
Griffon Vulture
Sardinia
30th June 2016
Quelle quantité cela représente ?
– Les charniers :
– Les 152 placettes individuelles :
– Les cadavres de la faune sauvage :
Soit un total de 230 à 240 tonnes / an

Quelle quantité cela représente ?
– Les 100 à 120 éleveurs « hors placette » :
Soit un total 60 à 90 tonnes/an La ressource totale est donc estimée entre 290 et 330 tonnes/an (utilisable) Cette ressource disponible connait des variations saisonnières mais est suffisante Cependant une grande partie est non maîtrisée
