A NEW LOOK AT

EXTREMADURA Because of their beauty, orchids and dragonflies are fascinating to many people who are interested in nature. However, unlike birds, they are much less well known to the public at large. This small guide aims to awaken curiosity, offering yet another reason to go into the field and enjoy the wonders of our surroundings. With such impressive natural resources, it is no surprise that Extremadura is also a paradise for finding these plants and insects. Of the 25 genera and about 90 species of orchids that can be found in the Iberian Peninsula, Extremadura boasts 13 genera. This guide covers the more common species, with a total of 44 species and one variety included. Similarly, with dragonflies, 56 species of the total of 79 present in the Iberian Peninsula have been recorded in Extremadura. If the following pages will help you to discover (and love) an Extremadura that you did not know, then they will have met their objective.

of Extremadura

INTRODUCTION any way devaluing the ecological value of other plants growing alongside them.

Over the past few years, interest in orchids has increased significantly and they are widely recognised as an attractive part of our natural world. The combinations of colours, their curious forms, their reproductive biology, the copious displays that can be found, the science about them, combined with the publication of a highly accessible reference book (the Guía de orchideas de Extremadura by Chiscano, Gil and Durán) in 1991 as well as information available in Proyecto Orchidea, has converted this family of plants to one of the best known and studied, at least in Extremadura.

The purpose of this small guide is twofold. First, to contribute to making this family of plants more accessible to those unfamiliar with them, giving yet another good reason to go out and enjoy nature. Secondly, to support the interest of those who are already starting their journey with orchids and to ensure continued awareness of the richness of the natural world around us. In both cases, to spread knowledge about a remarkably interesting part of our natural resources, to motivate curiosity and get connected to our rich natural heritage.

For both nature-lovers and photographers (and for those who combine both hobbies) orchids have an incredibly special and unique attraction, without in

ORCHID HABITAT The region of Extremadura, from the point of view of natural vegetation, is the meeting place between Atlantic vegetation (represented by deciduous woodland of Pyrenean oak and sweet chestnut, on higher elevations) and typical Mediterrean vegetation (dominated by evergreen species adapted to summer droughts such as holm oaks, cork oaks and a rich scrub flora, dominated by rock rose and heaths). In terms of soils, acidic terrain is abundant, derived from the presence of rocks such as granite, quarzite and slate, although basic or neutral soils can also be found because of limestone outcrops. The latter are scarce in Cáceres province but rather more extensive in the mountains of Badajoz. Although some orchids do not have soil preferences, many others are more selective, particularly those favouring neutral or basic soils, generally found over limestone, diabases and tertiary sediments.

The orchids in Extremadura form part of the plant community associated with the soils in which they grow, appear mainly in the following habitats:

01

MEDITERREAN WOODLAND 02 WITH CORK OAK AND HOLM OAK

DRY LIMESTONE SCRUB AND MEADOWS

Frequent in Extremadura, especially in Badajoz, as stages of the degradation of Mediterranean forest and dehesa, appearing as areas with shrubs adapted to the Mediterranean summer drought, with dry meadows in clearings and bare ground on both flat terrain as well as hillsides. In these zones, and especially on basic (high pH) or neutral soils, most of the Anacamptis species (A. pyramidalis, A. coriophora) can be found. Aceras anthropophorum and Himantoglossum robertianum prefer somewhat moister meadows.

Well-conserved habitat on hillsides, with a good canopy of holm oaks, cork oak or Portuguese oak. This habitat offers plenty of leaf litter and humus for orchids of the families Limodorum, Epipactis, Neotinea and some Anacamptis (like A. morio).

MEADOWS IN OPEN 03 WOODLAND AND OPEN COUNTRY With the loss of forest, principally for livestock farming, pasture with grassy hollows are formed, usually with some trees

remaining. In these environments, the predominant orchids are Serapias (such as S. perez-chiscanoi, S. lingua, S. vomeracea, S. cordigera), Anacamptis (such as A. champagneuxii, A.coriophora) as well as some of the Ophrys and Himantoglossum robertianum in more limestone areas.

DECIDUOUS WOODLAND 04 (OAK AND CHESTNUT) This type of woodland dominates large areas of the mountains of the north of Cáceres province, from the Sierra de Gata up to Hervás, the Jerte valley and La Vera. The soil is formed by a layer of mulch rich in rotting leaf litter and humus with shade-loving plants. It is the preferred habitat for species of Cephalanthera, Neottia, Limodorum, Epipactis and some Orchis (O. mascula, O. langei) and Dactylorhiza (D. insularis, D. sulphurea).

DAMP AREAS (EDGES OF 05 STREAMS AND RIVERS, WATERLOGGED AND BOGGY SITES) Some orchids need very moist conditions and prefer to be close to water courses or seasonally wet pasture or boggy sites. These include Anacamptis laxiflora, Spiranthes aestivalis and S. spiralis and some species of Dactylorhiza such as D. elata and D. maculata.

ADVICE AND RECOMMENDATIONS 01

02

03

All species are of great value, but in addition there are some with a legally recognised level of protection. To enjoy orchids does not mean, under any circumstances, risking their conservation by manipulating, damaging or collecting specimens. As we walk to look for orchids, it should be done in a careful manner, given that often because of the size of the plant, they can be difficult to locate amongst the foliage of other vegetation. Always respect footpaths, fences and property on our walks.

Extremadura

DRAGONFLY AND DAMSELFLY EXTREMADURA, AN IDEAL DESTINATION FOR DRAGONFLY ENTHUSIASTS The great variety of aquatic ecosystems and their good state of conservation makes Extremadura an ideal place to visit to look for more than 50 species of dragonfly and damselfly. The north and east of Extremadura have the highest species richness, where it is possible to find in a single 10 km square up to 43 species. The richness declines as one heads south towards the province of Badajoz.

Its geographical position enables not just more common species to be seen, but also 90 % of the more typically North African species that have been found in Spain, such as Anax ephippiger, Paragomphus genei, Orthetrum trinacria, Orthetrum chrysostigma, Brachythemis impartita, Crocothemis erythraea, Trithemis annulata, Trithemis kirbyi or Selysiothemis nigra. However, in the northern third of the region, we can also find species from higher latitudes such as Libellula quadrimaculata, Pyrrhosoma nymphula, Aeshna juncea or Cordulegaster boltonii.

The lucky visitor could observe some species that are particularly rare because of their scarcity or erratic distribution, such as Sympetrum meridionale, Diplacodes lefebvrii, Sympetrum sanguineum, Onychogomphus costae, Gomphus simillimus or Aeshna cyanea. This guide will help the visitor to get to know a group of species, present on Earth for over 300 million years, where rivalry, cannibalism, love rituals, hunting strategies or territorial defence are key for their survival in their aquatic habitat.

The quality of Extremadura’s ecosystems means that they host nationally important populations of Coenagrion scitulum, and of the most-threatened species at a national level, now protected, and relatively easily found. These include Coenagrion mercuriale, Coenadrion caerulescens, Gomphus graslinii, Oxygastra curtisii and the most threatened species, Macromia splendens, listed as in Danger of Extinction, which is present in some of the best conserved stretches of Extremadura’s rivers.

DRAGONFLY AND DAMSELFLY HABITATS gomphus forcipatus, Gomphus simillimus, Orthetrum trinacria, Platycnemis acutipennis, Oxygastra curtisii and Macromia splendens.

RUNNING WATER RIVERS. FAST-FLOWING UPPER COURSES AND GORGES Stretches situated at higher altitudes in V-shaped valleys, with clean well-oxygenated, permanent water. Sometimes water flow will be torrential. The narrow water courses have beds of rock or large pebbles. Aquatic vegetation is almost absent. Typically there will be alder or willow gallery woodland and sedges (Carex sp.) may be present in the water or along the banks. Precipitous mountain torrents have characteristics like the upper courses of the rivers and are found in the northern third and in the east of the region. Species include niche specialists like Calopteryx haemorrhoidalis, Cordulegaster boltonii, Onychogomphus uncatus, Aeshna cyanea, Boyeria Irene, Calopteryx virgo or Calopteryx xhantostoma.

RIVERS. LOWER COURSES. As the river descends to lower altitudes it may be more vulnerable in drought years to be reduced to a series of pools of different depths. The watercourse is wide with the riverbed of sand and silt. The water is more turbid and warmer. The banks will have more stable vegetation, with clumps of poplars, ash, willow and elm with patches of rushes and barer zones. Aquatic vegetation is abundant, especially with species of Ceratophyllum or Myriophyllum and areas of reed mace and reed, creating a great variety of microhabitats. Here can be found Anax imperator, Ischnura graellsii, Anax parthenope, Gomphus pulchellus, Lestes barbarus, Sympetrum fonscolombii, Orthetrum chrysostigma, Trithemis annulata and Onychogomphus costae.

RIVERS. MIDDLE COURSES Presence of permanent water where the gradient and speed of flow is less. The river widens and gets deeper. The riverbed will comprise rock, gravel and sand. The riverine woodland is dominated by ash, willows and brambles and there will be patches of shade alternating with sunlit zones. Thanks to this varied ecosystem there will be a large number of microhabitats favouring the presence of species of both upper and lower courses: Calopteryx haemorrhoidalis, Lestes viridis, Boyeria Irene, Calopteryx virgo, Platycnemis latipes, Onycho-

SEASONAL STREAMS These are water courses that during some months of the year will not have flowing water, being reduced to small shallow pools. The bankside vegetation is formed by galleries of oleander and tamujo bushes, with scattered trees (ash, oak and willow). The water surface will be highly exposed to sunlight. These zones are occupied by opportunistic dragonfly species typical of spring and autumn such as Ischnura graellsii, Anax imperator, Erythromma lindenii, Anax parthenope, Brachythemis impartita, Lestes

viridis, Crocothemis erythraea, Lestes barbarus, Sympetrum fonscolombii, Orthetrum chrysostigma, Trithemis annulata and Sympetrum striolatum.

STANDING WATER MAN-MADE POOLS AND LAKES Aquatic habitats of artificial origin that collect rainwater or run-off. They are usually created for livestock or irrigation. They vary in size, from less than a hectare to several hectares. The water surface is stable, but there will be strong variations in depth through the year. Often have a border of herbaceous or shrubby vegetation on the banks. The bed will be silty. Aquatic vegetation may sometimes be absent. Tend to be colonised by generalist species such as Ischnura graellsii, Sympetrum fonscolombii, Orthetrum cancellatum, Crocothemis erythraea or Trithemis annulata.

BOGGY AREAS Tend to be in poor acid soils and are permanently moist or waterlogged. There are carpets of Sphagnum moss and cross-leaved heath (Erica tetralix). There are few species, but they are highly specialist, like Pyrrhosoma nymphula, Ischnura pumilio, Coenagrion mercuriale, Libellula quadrimaculata and Orthetrum coerulescens. IRRIGATION CHANNELS Here we refer to traditional earth-sided irrigation channels to provide water to meadows in mountainous areas in the north of Extremadura. They have a width of no more than 50 cm and are very shallow. We can find specialist species such as Coenagrion mercuriale, Pyrrhosoma nymphula, Cordulegaster boltonii, Ceriagrion tenellum and Orthetrum coerulescens.

GLACIAL LAKES These are high altitude lakes that in Extremadura are found in the Gredos Mountains. They have permanent water, which is very cold and well oxygenated, supplied by nearby springs with depths that vary from one to four metres and with an area of less than a hectare. In spring and summer aquatic vegetation will appear and the banks will be herbaceous. There are few species, but all noteworthy like Pyrrhosoma nymphula, Aeshna juncea, Libellula quadrimaculata and Cordulegaster boltonii.

Common Darter (Sympetrum striolatum), flying in tandem.

RESERVOIRS Head reservoirs can be found at higher altitudes and are smaller in area and surrounded by dense woodland and scrubby vegetation on the banks. The water is cold with high oxygen levels and has aquatic vegetation. Here there are species typical of both upper courses of rivers as well as damned water bodies such as Libellula depressa, Erythromma lindenii, Sympetrum striolatum, Lestes barbarous or Anax imperator. In addition, at some of the better head reservoirs we can find Libellula quadrimaculata, Gomphus graslinii, Gomphus simillimus, Oxygastra curtisii or Macromia spendens. Reservoirs at middle course or lower course will tend to be larger. The supply of water may or may not be permanent. They suffer great fluctuations in depth in the summer, leaving bare banks, with nearby grassland. Aquatic vegetation is scarce. Amongst typical species of this habitat are Ischnura graellsii, Erythromma viridulum, Sympetrum fonscolombii, Anax imperator, Anax parthenope, Brachythemis impartita, Orthetrum trinacria, Aeshna mixta, Crocothemis erythraea and Trithemis annulata.

GOOD PRACTICE FOR WATCHING DRAGONFLIES

Having a pastime in which other living creatures are involved means that a series of ethical norms should be followed that allows one to enjoy nature, without interfering with the life cycle of these species. So, if you want to get to know and enjoy the experience of watching dragonflies, you should follow the following recommendations: 01

THE GUIDE IS YOUR BEST ALLY. Get to know these species with a professional guide who is experienced with this group and understands their biology.

02

AVOID CAPTURING IF POSSIBLE. The identification of dragonflies, in most cases, does not require capturing individuals, use binoculars to recognise them.

03

CAREFUL, YOU ARE KILLING ME. If you do capture an example to identify it, handle it with great care. They are very delicate animals and you could cause their death. Always return them to nature in perfect condition.

04

THE LITTLE ONES, NO! Never capture or handle immatures (recently emerged and lacking adult colour).

05

COMPLY WITH THE LAW. Some species are protected because they are threatened species and should never be disturbed.

06

THE BEST COLLECTION…MY FILE OF PHOTOGRAPHS. Collections of insect specimens are prohibited by law unless for scientific purposes, for which relevant permits must be granted.

07

DO NOT INVADE THEIR SPACE! When taking macrophotographs do not interfere with the life cycle of the insects or damage their habitat.

08

COLLABORATE FOR THEIR CONSERVATION! Send information about the species you identify to the relevant authority for their conservation vidasilvestre.secona@juntaex.es
