Caring for the capercaillie in Areej to increase its population

primary
ONF carried out work to improve the biotope capercaillie. This involves increasing the areas suitable for its annual cycle, especially during the breeding period.

How many will there be in three or four years during courtship shows in the jungle of Punak State? Pascal Labin, Regional Forestry Technician at the National Forest Office in the western sector of Coziran, estimates their number at “about seven to eight roosters, males, in the Orly Valley according to the censuses we take every year chiefly in May, and we may consider that we have the same Number of females “An infallible way of doing an inventory because none of them miss the call” at the song’s place, getting up early enough to estimate the show.
The symbolic bird of the Pyrenees, the capercailie is the subject of all the attention. The state of its conservation is perceived as “medium”, and then work is completed to create conditions for its further development. “The population tends in the best cases to stabilize in terms of numbers, even decline in certain sectors, notes Pascal Lapin, who said, in the Orly Valley and at this Natura 2000 site, we still have a healthy population.”
The work focused on several bioenvironments “with the aim of increasing the capacity of environments conducive to the breeding of species, i.e. hens and potential broods. And how do you make the environment attractive? By taking it through feelings… by working twice as hard on” the lower layers, i.e. plant-level environments The land is composed mainly of blueberries. These berries are a very important plant for the feeding of these birds, as are berries and many other herbs … “
All these little people had enough to click on the spot’ but the lower layers were under very large forest cover, so the intervention was to cut down the beech trees which were too many. Put them at a distance of eight to ten meters to let the light pass on the ground preferably Develop blueberries at first, then blueberry fruits a second time. »

Before you can measure the impact of the work done
On the site, the so-called “throat” wood is available to visitors. What is it about? “These are the trees we leave standing from which we remove bark everywhere. The circled beech will dry out so there will be no more shade for these fir trees on either side. Keeping dead wood is very interesting for other types of birds such as woodpeckers and warthogs. Hazelnuts feed on insects that live in dead wood.
Another scenario in these areas, “The coniferous trees were planted about twenty years ago, Scots and hook-pine, the species consumed in winter by the Capercaillie which in winter feed mainly on needles, if necessary, the work that was carried out consisted of removing Pine trees, under the cover of beech wood, in order to accentuate them and promote their growth.”
With the site now complete, NFB will now allow nature to do its work. “The trees that were cut down on the ground, we left them almost as is
And now we’ll allow the environment we’ve made to evolve naturally, in the hope that what we’ve been able to do will be really useful. »
It is already too early to assess the full scope of work done on the environment. “We will really be able to judge the impact of this work on these lower classes, which will be highlighted in four years. We record for relatively long periods. That is the whole meaning of the work when you work in the forest, you realize the results of the investment over time.”
An investment that should also benefit other species of birds and mammals. “Through this distinction, we are trying to generate an abundance of food and biotopes.”
