Abstract
En el trabajo se realiza una caracterización de las
variaciones estacionales de la humedad del sustrato de los
brezales húmedos de la Serra do Xistral (Lugo, Galicia), y
se compara con la humedad de los diferentes ecosistemas
que forman la catena vegetacional en la que se enmarcan,
así como con la de otros tipos de humedales estacionales.
La representatividad de este territorio ha conllevado su
inclusión en la Red Natura 2000, mediante la designación
del Lugar de Importancia Comunitaria (LIC) Serra do Xistral
(ES1120015). Los datos presentados ponen de manifiesto
un funcionamiento ecológico homogéneo de los brezales
húmedos en relación al resto del complejo húmedo, así
como su funcionamiento inequívoco como ecosistemas
húmedos. Por tanto, se confirma el diagnóstico de los
brezales húmedos de las Sierras Septentrionales gallegas,
vinculados al tipo prioritario Nat-2000 4020*, incluido en el
Anexo I de la Directiva Comunitaria 92/43/CEE. El
diagnóstico y caracterización de los tipos de hábitat debe
considerar la estructura, composición y funcionalidad
ecológica, mediante el empleo de conocimientos científicos
y técnicos. Esto resulta de vital importancia, sobre todo para
la conservación de los tipos prioritarios, evitando la puesta
en marcha de planes y proyectos sin una adecuada
evaluación de sus repercusiones
In this paper we have performed a characterization of the soil moisture in several wet heaths from Serra do Xistral (Lugo, Galicia), to be compared with that in the different ecosystems existing at the same vegetation catena, as well as other seasonal wetlands in the region. The representativeness of this territory has led to its inclusion in the Natura 2000 network, by designating the Site of Community Importance (SCI) Serra do Xistral (ES1120015). The data presented show a homogeneous ecological functioning of wet heaths in relation to the rest of the wet complex, and sustain their unambiguous operation as wet ecosystems. Therefore, it confirms the diagnosis of wet heaths in the northern mountains of Galicia, linked to priority type Nat-2000 4020*, included in Annex I of the EU Directive 92/43/EEC. The diagnosis and characterization of habitat types should consider the structure, composition and ecological functionality through the use of scientific and technical knowledge. This is of vital importance, particularly for the conservation of priority types, avoiding the implementation of plans and projects without a proper impact assessment
