8.2 AMPHIBIANS AND REPTILESA total of nine species of amphibians were found in the area of study, as well as fifteen reptile species. Thewater ponds and tanks which were visited to put up mist nets there proved to be particularly interesting forthe observation of amphibians too. Especially at night, many animals could be found both in and aroundthese reservoirs and Marbled newts, Bosca’s newts and Fire salamanders (mostly larvae) were frequentlyrecorded this way. Also, Midwife toads could be seen (and heard) here. At several locations a Viperine snakewas also seen, swimming by underwater.The Golden-striped salamander was seen alongsidethe streams northeast of Loriga. This species isendemic to north-western Spain and northernPortugal. Just as is the case for the Pyreneandesman, the area in which the Golden-stripedsalamander occurs is limited by the large amount ofprecipitation it requires. Iberian frogs could be seeneverywhere in the small streams, while Perez’s frogsand Tree frogs were locally abun<strong>da</strong>nt in the smallbogs higher up in the mountains.The Schreiber’s green lizard could be foundregularly, especially near streams and bogs in thehigh mountains. The species was even accidentallycaught sometimes in one of the Longworth traps.Iberian wall lizards were very abun<strong>da</strong>nt on the wallsalongside roads, in the vicinity of villages and onrocks. Sometimes a Large psammodromus wasobserved as well and in some locations high in themountains, Iberian Rock lizards were seen. InPortugal this species is known only from the Serra <strong>da</strong>Estrela. In abandoned homes and buildings, Wallgeckos were seen regularly.Snakes were occasionally found, either alive or dead.Most of the time, it was either a Montpellier snake ora Ladder snake. Unfortunately, the European viperwas seen only once. A relatively young Southernsmooth snake was brought to the camp (see picture).Marbled newt could be found in several water tanks.A young Southern smooth snake was brought to the camp site.Photo: Bart NoortPhoto: Kees Mostert8.3 BUTTERFLIESDuring our stay, 53 butterfly species were found. The most uncommon species were seen in the higher partsof the mountains in the area around Lagoa Compri<strong>da</strong>. Black satyr, Striped grayling, Large wall brown, Bathwhite, Southern brown argus, Silver studded blue, Esper’s marbled white, Iberian marbled white, Duskymeadow brown and Lulworth skipper could be spotted there regularly. Many other species were observed inthe lower regions of the park. Some of them were species which are widespread throughout a large part ofEurope. The most numerous species were Scarce swallowtail, Gatekeeper, Southern gatekeeper, Greatbanded grayling, Clouded yellow and Lang’s short-tailed blue.The edges of the forests in the region are rich in herbs, on which Blue-spot hairstreaks were surprisinglyabun<strong>da</strong>nt, particularly on Apple mint (Mentha suaveolens). Also, False ilex hairstreaks were seen regularlyhere, as were Provençal fritillary and Queen and Silver-washed fritillary. In half-open landscapes, theCardinal was abun<strong>da</strong>nt. Other species that could be found here were Small skipper, Dingy skipper, Purpleshotcopper, Scooty copper, Spotted fritillary and Southern white admiral. In the old chestnut forests, Rockgraylings were seen regularly.38 Dutch Mammal Society
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
