Parc animalier de Sainte-Croix Parc Animalier de Sainte Croix

Last wednesday Sainte-Croix sent 10 (4.6) western capercaillie chicks born last spring to a breeding center in Pražmo, Czech Republic. The birds will breed there and their chicks will be released in Beskydy mountains area.
It it the second time the park sent animals for this program (first time in 2022 with 1.4 birds).

A great project and the population has increased by 90% ... it seems.

This project is great in its intentions and on paper. I applaud the French zoo for its involment and goodwill. I hope my futher text is not seen as criticue of parc animlier de sainte croix.

However in reality, mortality of capercillie chicks released from both current Czech breeding facilities in Beskydy mountains and Šumava is 100% - since beginning till today. I had seen some internal report papers and unfortunately, most their chicks perish within 2 weeks and basicaly non survive first year. Zero proven breeding of released birds within last 50 years of captive-bred bird releases.

The only good capercillie population left in Czechia is in Šumava mountains. And it currently grows due reasons that are not fully understood by wildlife officials / researchers. What probably helps is large-scale protection measures done in national park and exclusive military area Boletice nearby. It includes closure of large patches of land for public, closed hicking paths (which provoked a lot of protests by both local people and tourists). There is also change in agro-forestry practices. Large-scale die-offs of fir trees due to bark beetle. Natural return of wolves into the area and recovery of lynx, both species suppress mesocarnivores like red fox (and that helps capercillie chick survival odds). But again, nobody really knows what of these changes actually has the most impact.

Capercilie population in Beskydy is miniature and continues to diminish and will soon die out. Despite releases of captive bred chicks.

This is a wonderful species, and any efforts to preserve and conserve it must be applauded.
In the UK the species went extinct and was re-introduced from Sweden in the last century, so it is certainly possible to do so.
But modern pressures, (disturbance, habitat loss/fragmentation and increase in predation) might mean we are unfortunately in a different World today.
The situation in Scotland looks bleak - with now only 532 birds left in the UK, apparently - Capercaillie - Cairngorms Capercaillie Project

Do you know why the Beskydy capercaillie population (aside the birds from captive-breeding for release) continue to decline in the wild. What are the main factors driving the gradual loss of birds from the Beskydy population?

Do authorities take note of work done by f.i. bustards in Europe and Middle East / North Africa where captive-bred birds are pre-trainer before release. How / What prep techniques do the managers use to improve the suitability and adaptability of captive-reared birds to the wild?

Five minutes of Googling produced this paper https://www.researchgate.net/public...program_in_Bory_Dolnoslaskie_Forest_SW_Poland
which contains data relevant to your question about survival in CZ in addition to the titled Polish project. It states that survival rates of released birds in Beskydy varied between just 23 and 139 days, and the main cause of death was predation mainly by foxes and martens.
This is interesting as at the same time the Scottish population has seen a catastrophic decline to just 500 birds, there has been a massive increase in the range and population size of the Pine Marten. The two factors have not been linked in the UK, so far as I can find - yet?

Unsure for exact reasons. Cited I have seen by different people fe sharp increase in tourist use of forests in this area (starting this year, hill Travný was closed for public hicking but just 1 hill is so little to make a difference). Also I saw degradation of understorey vegetation by red deer overstocking (local hunters provide so much artificial food that deer overgraze). Sharply increased clear-cut logging in the mountains. Wild development of various infrastructure, summer houses, fencing, new forest roads everywhere.

All of those disturbance issues, along with the level of predation are very bad news for the species, which needs large undisturbed areas.
I have not seen any evidence of the same level of development disturbance and habitat degradation in Scotland, unless re-wilding is reducing the area of pine forest - so there perhaps, the finger points at increased predation.
The Polish study I cited, implicates digestive issues due to shorter and less well developed intestinal tracts in captive-reared birds leading to starvation, but this does not seem to fit so well with birds which are surviving for many months, unless maybe it is seasonal? There seems to be a need for detailed follow-up studies.

Their intestinal tract changed with the seasons, being much larger during the winter (when they survive on low-quality food that is high on fibre). This problem can be avoided by feeding them already in captivity a natural diet. If they receive some pellet-food, then this should be the special high-fibre grouse food. But they should especially start feeding the animals after the summer natural vegetation, to allow the caecum to develop. I guess (hope) that they know this. It is true that introductions of grouse are rarely successful, probably also because the habitat is still a problem. But we need to continue trying, if we do not want to loose the species in all countries. Change of forestry management, too many deer and wild boar, too many predators and especially too many tourists make survival difficult, and climate change will also affect the vegetation. Doesn't look very well for the grouse in most countries!
 
Can this park be visited without using your own car to drive trough the exhibits ?
You must have confused this for another Park. You never need your own car to go through the exhibits, it's exclusively walking. There is a train that ho through some exhibits, but it's completely optional
