population of predatory species such as iberian imperial eagle (aquila adalbert) or black vulture (Aegypius monachusThreatened species increased “very significantly” in Castilla y León, according to results from the latest monitoring report of the Community Biodiversity Conservation Status Monitoring Plan. The imperial eagle was on the verge of extinction in the mid-20th century and is catching up across the Peninsula.
In the example of the imperial eagle, a total of 131 provinces were counted and distributed across provinces in 2021 (the last year for which data is available). segovia (47) Avila (43) valladolid (27), Burgundy (6), Palencia (3), Salamanca (3) and Zamora (1), as reported by Junta de Castilla y León sources in a statement compiled by Europa Press.
Full reproduction monitoring performed 118 pairsA total of 190 chicks were flown in 104 different regions. These results show that the population trend of the imperial eagle in Castilla y León is “clearly positive”, It increases from 17 regions where the species lives in 1989 to 131 in 2021.
This strong population growth was accompanied by a significant population increase. increase in distribution areaSince moving from the ten-ten-kilometer 6 or 7 UTM grid the genre occupied in 1989 to the 94 grid in 2021.
Black vulture is also getting better
On the other hand, in the census Black vulture of 2021 recorded 597 pairs scattered across 7 nest cores and 23 breeding colonies.
Full reproductive monitoring was performed in total. 590 pairs, a total of 363 chicks were flown. The species is distributed in the states of Ávila (269 pairs), Burgos (15), Salamanca (120) and Segovia (193), confirming its positive trend in the number of units increasing from 134 pairs to 597 in 1991. , as well as in the recovery of part of the historical distribution area (with an increase of 20 UTM grids by ten by ten kilometers between 2000 and 2021).
Fixing power lines
Junta de Castilla y León blames this for the growing population implementation of remedial measures for dangerous power lines.In addition to the sustainable forest management practices implemented in Castilla y León, “the presence of forest planning and management tools in public and private forests whose purpose is the conservation and restoration of forest masses as well as the preservation of existing biodiversity” is within them.
The district administration has been promoting the application of management criteria compatible with forest types for nearly two decades. a guide describing management criteria Constituting the bulk of the Community’s forest masses and whose purpose is to harmonize forest management and use with species conservation.
Complementarily, approval and forest certification of forest management tools under the PEFC and FSC seals has been carried out in Castilla y León. Specifically, the Community offers 1,011,932 hectares Land with forest planning certificate, 775,045 of which is managed by the Board and the rest is forests under special regime.
In the special case of the imperial eagle, about 31 percent (41 regions) of the 131 sites found in 2021 were in the mountains with planning tools in place (65 percent). total area of 40,460 hectares the number of forests managed by forest planning tools, with the presence of the king eagle.
Of the 597 pairs found, in the case of the black vulture, 471 are located in forests classified as public services., for 126 regions in forests under a special regime. The percentage of couples in public and private forests with a forest management tool in effect increases to 72 percent (428 couples), and 84 percent of the forests are managed by the Junta de Castilla y León (32 forests classified as public service planning tools in effect), and the percentage 16 of them are privately managed. This represents a total area of 76,728 hectares with forest planning tools where black vultures are found.
threats
Today’s most important threats relates to the death of samples as a result of collision and/or electric shock in power lines.Mortality from human activities such as reduction in certain areas of the main prey species, the rabbit (in the case of the monarch eagle) and from natural causes in the nest and/or work-related disturbances during the breeding season for recreational activities in various species (agriculture, hunting, forestry) and in the areas surrounding the nests. .
The various forest uses they offer, located in the mountains with a planning tool in place, both in their planning and as in the programming of silvicultural activities It will be conducted in a way that enables both the conservation, rational use and continuation of forest masses and the establishment, stabilization and spread of these species in Castilla y Leon.
