Pinetum uncinato-pyrenaicae ass. nova hoc loco (74.3.2)

(Junipero intermediae-Pinion catalaunicae, Junipero sabinae-Pinetalia sylvestris, Junipero sabinae-Pinetea sylvestris)

Typus associatio: Table 71, rel. 12 [Huesca: Benasque, El Paso Nuevo. 42º38"15"'N-0º33"30"'E. 1370 m, N, 25%, 200 m2].

Characteristic species (territorials): Pinus sylvestris var. pyrenaica, Pinus uncinata, Pinus sylvestris var. pyrenaica x Pinus uncinata (Pinus xrhaetica nothovar. bolosii), Juniperus communis var. intermedia (prox. Juniperus communis subsp. hemisphaerica), Buxus sempervirens.

Diagnosis: Central Pyrenean supratemperate humid and hyperhumid (on steep sunny slopes) semicontinental natural potential coniferous mesoforest community, growing on rich and poor substratum but with an acidic upper organic horizon. In this natural pineland forest community the commonest tree is Pinus sylvestris var. pyrenaica, but also is abundant Pinus uncinata as well the natural hybrid between both (Pinus xrhaetica nothovar. bolosii). In the understory as scrubs are common Juniperus communis var. intermedia (often close to Juniperus communis subsp. hemisphaerica) and particularly Buxus sempervirens, but are scarce Juniperus communis subsp. nana and Juniperus sabina (except as relict in exposed sunny biotopes); it is also conspicuous the grass chamaephyte layer of Festuca gautieri and Avenella flexuosa.

Potentillo anserinae-Agrostietum stoloniferae ass. nova hoc loco (59.13.1)

(Agrostion stoloniferae, Plantaginetalia majoris, Molinio-Arrhenatheretea)

Typus associatio: Table 72, rel. 4 [León: Crémenes, Las Salas. 30TUN2955. 1000 m, 6 m2].

Characteristic species (territorials): Agrostis stolonifera, Potentilla anserina, Senecio aquaticus.

Diagnosis: Hygronitrophilous meadows growing in sandy-stony soils on the banks of the rivers prone to flooding, influenced by anthropozoogen actions. They seem to have their best development in the supratemperate humid-hyperhumid belt of the Ubinnean Subsector (Orocantabric Subprovince). They belong to the edaphohygrophilous series of the shrubby willow formations of the Salicetum cantabricae and the ash woods of the Euphorbio hybernae-Fraxinetum excelsioris, where they sometimes grow under the protection of the river trees in contact with megaforbic communities of Chaerophyllo-Valerianetum pyrenaicae and Filipendulion ulmariae, both occupying the nearest areas to the water channel.

Characteristic species (territorials): Avenella iberica, Jasione laevis subsp. carpetana, Juniperus alpina, Pinus sylvestris var. iberica.

Diagnosis: Orotemperate submediterranean humid and hyperhumid Pinus sylvestris var. iberica microforests (mesoforests only in lower altitudes on deep soils), growing between 1700-2100 m in siliciceous medium acid tangel cambisols or rankers, covered by winter snow for at least five months, in the high mountains of Sierra de Guadarrama (Iberian Central Range). At lower altitudes 1500-1850 m in expositions and soils where Quercus pyrenaica, Quercus petraea or Betula celtiberica deciduous forest can"t grow, the Avenello-Pinetum ibericae forests are replaced by the also primary or locally old secondary Guadarramean Iberic Scots pine mesoforest association Pteridio-Pinetum ibericae rich in Querco-Fagetea and Cytisetea scopario-striati species.
