8.4 DRAGONFLIESIn the area of study, 22 dragonfly species were recordedduring the summer camp. Since very little is known about thedragonflies of the Serra <strong>da</strong> Estrela, many of the speciesrecorded were welcome additions to the list of speciesalready known from the park. Along the streams northeast ofLoriga, White featherleg, Beautiful demoiselle, Copperdemoiselle, Large pincertail and Golden-ringed dragonflywere abun<strong>da</strong>nt. Western spectres were also seen, althoughthis species was not as numerous. In the bogs in the highmountains, lots of Robust spreadwings and locally also Smallspreadwings were present. Above the ponds, mainly Fourspottedchaser, Common blue <strong>da</strong>mselfly and Red-veined<strong>da</strong>rter could be seen zooming around. At one location, bothLarge red <strong>da</strong>msel and Small red <strong>da</strong>msel were seen.Two previously unknown sites for the Moorland hawker werefound. This species is very rare in the Serra <strong>da</strong> Estrela andthe Serra is the both the only location in Portugal and thesouth-westernmost location in Europe where this species isknown to occur. While checking the live traps, summer campparticipants found an individual which had been unable tofully emerge from the larval skin (see photo). In the lowerparts of the Serra <strong>da</strong> Estrela, species such as Blue emperor,Keeled skimmer, Migrant hawker and Blue hawker werespotted.A Moorland hawker experienced some difficulties tryingto creep out of its larval pellicle.Photo: Kees Mostert8.5 PLANTSSome attention was given to plants as well. Unfortunately,the end of July and the beginning of August are not verysuitable for a plant <strong>survey</strong> of a southern European region.Nevertheless, 211 different species were recorded in theSerra <strong>da</strong> Estrela. Since this report is written mainly for thesake of <strong>mammal</strong> study, the different vegetation zones of theNatural Park and the characteristic plant species will not bediscussed here, but a list of plant species can be found inappendix 8. One of the most valuable areas for plantsproved to be the boggy area near Lagoa Compri<strong>da</strong>.Flowering specimens of Veratrum album could be foundhere, together with hundreds of Marsh gentians. Throughoutthe Natural Park, Ivy-leaved bellflowers could be found in<strong>da</strong>mp and shadowed places. This species is almost extinct inthe Netherlands.Hundreds of Marsh gentian could be seen near LagoaCompri<strong>da</strong>.Photo: Jeroen WillemsenMammal <strong>survey</strong> Serra <strong>da</strong> Estrela - Portugal 2009 39
