Project description:
Background
The SCI ‘Aiako Harria’ is located at the foot of the Pyrenees Mountains, in the
west corner of Gipuzkoa province (Basque Country). This 6 913 ha area is
characterised by a succession of deep valleys and high slopes. While most of its
surface is now covered by pine, there are still remarkable areas of native forest,
such as the Añarbe oak-beech forests, the Endara oak forest and the Oieleku
beech forest. The area is also home to other ecosystems with high biodiversity,
such as silica rock formations and those linked to small rivers. The wildlife is
typical of the Euro-Siberian area, with more than 147 species of vertebrates,
including wild boar and roe deer in forest areas, griffon vulture on rocky slopes
and salmon in the rivers. However, pressure on land for recreational uses is
increasing; in particular, picnic areas have been created, with direct road access. Objectives
The overall objective of the project was to conserve and restore habitats and
species of Community interest in an area which is predominantly forested. The
project would focus on the protection, restoration and expansion of two natural
habitats of Community interest in the Aiako Harria Special Protection Area (SPA):
the Atlantic acidophilus beech forests and the Galaico-Portuguese oak woods.
These measures would have a positive impact on populations of coleopterons
(beetles) such as Rosalia longicorn (Rosalia alpine) and stag beetle (L u c a n u s
(beetles) such as Rosalia longicorn (Rosalia alpine) and stag beetle (L u c a n u s
cervus), and would allow the establishment of others, including the hermit beetle
(O s m o d e r m a e r e m i t e) and the great Capricorn beetle (Cerambyx cerdo), all of
which are of Community interest (and, as such, listed in Annex II of the Habitats
Directive). Measures would also be taken to restore fluvial habitats and species,
particularly the Alpine snowbell (Soldanella villosa), given the importance of
Aiako Harria for the global conservation of this species. Results
The project completed most of the foreseen actions by its end date. It
contributed to the restoration and improvement of the conservation status of the
target Community habitats and species populations. The actions linked to the
improvement of the Pyrenean Desman (Galemys pyrenaicus) were not
undertaken, however. After a thorough analysis of the constraints and collateral
effects on the habitat alluvial forests with Alnus glutinosa and Fraxinus excelsior
, the cost-effectiveness of the actions was not sufficiently clear. A major achievement of the project was the launch of several innovative lines of
research (such as entomofauna monitoring). Such research initiatives are
expected to yield useful information for implementing sustainable forestry
management. Prior to the project, information on techniques to improve the
conservation status of the forest ecosystem was lacking in Spain. The project
introduced some pioneering techniques that can carried out in other similar
areas.
Specific results of the project include: Drawing up of a restoration plan for the replacement of 287.7 ha of
land (19% more than initially expected) covered with exotic conifer
masses with habitats of Community interest in the communal forestry
areas ‘Añarbe’, ‘Usoko-Epelerreka’ and ‘Kausua’. Purchase of 54.2 ha (8% more than foreseen) of private land to restore
habitats Atlantic acidophilous beech forests and Galicio-Portuguese
oak woods with Quercus pyrenaica.ha
Study of the conservation status of Galemys pyrenaicus h a b i t a t
(Pyrenean Desman) and minimum flow critic for species in the stream
Tornola (basin of the river Oiartzun). Study of the physical habitat and retention capacity of the riverbeds
flowing into the Añarbe reservoir. This study was undertaken with the
objective of determining the simplest riverbeds in terms of structure
and functionality where wood introduction was conducted. Designing of a technical project to increase the structural complexity
and the retention capacity of organic matter and sediments in the
riverbeds flowing into the Añarbe reservoir. Determination of the habitat cartography in EUNIS format in the
context of the SCI. Study on the diversity of forest invertebrate species of Community
interest in the context of the SCI, emphasising threatened coleopterons
species typical of forest environments and dependent on the
availability of dead or decrepit wood, included in the Annexes II and IV
of the Directive 92/43/CEE.
Several key improvements were also made to the following habitats: Acidophilus
beech forest (habitat 9120): Increase of the area by 236 ha, starting from grown up exotic conifer
plantations (38% more than the existing habitat surface in 2005) and
protection of indigenous understorey in 22.5 ha of fully grown exotic
broadleaved plantations. Improvement of the conservation status of 32 ha by means of increasing the
structural complexity of the habitat. Natural regeneration started in 20 ha of
the Oianleku acidophilous beech. Restoration of an additional 64 ha of this habitat after the project end.
Galicia-Portuguese oak wood (habitat 9230): Increase of the area by 12 ha (more than 50% of the mapped area in 2006). Improvement of the conservation status of 3.3 ha by means of the creation
of a firebreak band. Rivers and riparian habitat (91E0*): Increase of the structural complexity of the riparian habitat along 700 m of
four different streams. Increase of the fish biomass, invertebrate density
and dead leaves and sediments retention. Contribution to the improvement
of the water resources of the Añarbe reservoir.
Increase of the knowledge on the habitat, its ecology, dynamic, and
measures for better management.
Finally, the conservation of the 1 ha area, where the Killarney fern (T r i c h o m a n e s
speciosum) can be found, and a strip of 20 m in each side of the riverbeds of the
upstream tributaries of the stream ‘Karrika’ for the protection of the Hairy
snowbell (Soldanella villosa) was ensured.
A wide dissemination campaign of the project’s result was carried out. As well,
bi-monthly news bulletins, an interactive CD and booklet for schoolchildren and
teachers and a travelling exhibition, the project organised an ‘International
Workshop on Conservation, Restoration and Management of forest and fluvial
SCIs’.
Even the external companies involved in the project helped to publicise the
project, which has led to a shift in attitude in favour of forest conservation and
restoration within the SCI Aiako Harria among the general public and private
landowners. As a result, the pollarding tradition is gradually being restored in
order to maximise biodiversity.
