It consists of two areas at different levels: The upper level is flat and fairly dry; the larger, lower area has a certain slope and is very waterlogged.<\/h5>\n<p>The two levels are joined by a slope covered with beech and pine trees, ferns and gorse. The following may serve as a general summary<br \/>\nIn the higher area, where peat has not developed or the deposit is shallow, we can distinguish between two areas with flowing water,<\/p>\n<ul>\n<li>the North, with dispersed flowing spring water, with great fluctuations in terms of flow and mesotrophic waters,<\/li>\n<li>the South, highly heterogeneous, with unstable flows which function on an irregular basis, as reflected by the presence even of dead young beech trees on the western boundary, and more acid waters.<\/li>\n<\/ul>\n<p>The <strong>lower, wet area<\/strong> is much larger, uniformly waterlogged and has a good deposit of peat (approximately 1.5 m deep).<br \/>\nAt the upper edge, there is a spring point from which minerotrophic waters flow and whose influence permits the growth of <i>Menyanthes trifoliata<\/i>, there also existing other outflow points which would appear to be fairly unstable in terms of situation and operation.<br \/>\nThis area has a channel on each side, the one in the west being shorter, shallower and narrower than the one on the eastern edge, which runs beneath a line of <i>Salix atrocinerea<\/i>.<br \/>\n<strong>Drainage<\/strong> takes place via a single stream leaving the area, where the peat deposit stops quite abruptly and emissions of methane and hydrogen sulphide can be detected.<\/p>\n<dl class=\"accordion\"><dt>MOST IMPORTANT VALUES<\/dt><dd><p><span style=\"color: #ff0000\"><strong>Uniqueness<\/strong><\/span><br \/>\nThe site can be considered one of the four <strong>peatlands, in the strict sense of the word, <\/strong><strong>detected in <\/strong>Navarre, and one of the only two which are unmistakeably active. The origin of the site is an extremely particular structure: a thrust fault forcing a significant pack of sandstone (permeable) on top of loamy rocks (impermeable), and its conservation is due to the constant, abundant flow from the aquifer hanging in the structure.<\/p>\n<p><span style=\"color: #ff0000\"><strong>Biological and ecological values<\/strong><\/span><br \/>\nThe vegetation in the peat-deposit area is noteworthy: <em>Eriophoro angustifolii-Sphagnetum rubelli.<\/em> The presence of <em>Pinus sylvestris<\/em> and <em>Betula pubescens subsp. celtiberica,<\/em> which could draw the site near to the status of bog woodland (91D0*), although of an extraordinarily poor nature due to both climate and orientation, is also worthy of mention.<br \/>\nAs far as plant species are concerned, the presence of <em>Menyanthes trifoliata, Sphagnum rubellum<\/em> and <em>S. fallax<\/em> (neither sphagnum had been cited in Navarre) deserves special attention.<\/p>\n<p><span style=\"color: #ff0000\"><strong>Historical and paleoecological values<\/strong><\/span><br \/>\nThe site has a considerable peat deposit (1.5 metres), yet to be studied.<\/p>\n<p><span style=\"color: #ff0000\"><strong>Habitats of Community Interest<\/strong><\/span><\/p>\n<table border=\"1\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td valign=\"top\" width=\"54\"><strong>H\u00e1bitat<\/strong><\/td>\n<td valign=\"top\" width=\"342\"><strong>Nombre<\/strong><\/td>\n<\/tr>\n<tr>\n<td width=\"54\">4010<\/td>\n<td valign=\"top\" width=\"342\">Brezales h\u00famedos atl\u00e1nticos septentrionales de\u00a0<em>Erica tetralix<\/em><\/td>\n<\/tr>\n<tr>\n<td valign=\"top\" width=\"54\">4030<\/td>\n<td valign=\"top\" width=\"342\">Brezales secos europeos<\/td>\n<\/tr>\n<tr>\n<td valign=\"top\" width=\"54\">6410<\/td>\n<td valign=\"top\" width=\"342\">Prados con molinias sobre sustratos calc\u00e1reos, turbosos o arcillo-lim\u00f3nicos (<em>Molinion caeruleae<\/em>)<\/td>\n<\/tr>\n<tr>\n<td valign=\"top\" width=\"54\">7140<\/td>\n<td valign=\"top\" width=\"342\">\u00abMires\u00bb de transici\u00f3n<\/td>\n<\/tr>\n<tr>\n<td width=\"54\">91D0*<\/td>\n<td valign=\"top\" width=\"342\">Turberas boscosas<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #ff0000\"><strong>Flora<\/strong><\/span><br \/>\n66 species of vascular plant and 39 bryophyte species, seven of which are sphagnums, have been recorded.<br \/>\nOf the vascular plants, the most noteworthy feature is the presence of the hybrid <em>Salix aurita x atrocinerea.<\/em> The abundance of <em>Lastrea limbosperma<\/em> and the presence of <em>Polygonatum verticillatum, Gentiana lutea<\/em> and <em>Convallaria majalis<\/em> among the birch and beech trees is also relevant.
