The Future Urban Development Plan Parla which is currently in the pipeline, poses a serious threat to the continuity of the many species that inhabit natural areas more representative of the municipality.
Thus places like the hill of the Cantueña, Humanejos the stream or the steppes of Parla Avutardera are serious threat of disappearing and with them their rich flora and fauna.
spite of the numerous evidences of the ecological values \u200b\u200bof these natural areas, repeated many times by environmental groups and some scientists , the various municipal governments have never taken into account.
In this way, has reached the current situation, when the current city government has decided to put a definitive end to these natural areas, as emblematic of Parla, not taking into account even the declaration of 2010 as the Year for Biological Diversity, as did other nearby municipalities, the which prepare the municipal nature reserves statement and / or develop their listings on biological diversity in order to preserve it. On the contrary to the claims parleño municipal government, whose sole aim is the destruction of all natural biodiversity at all costs, steadily denied their existence with no arguments, only giving priority to urban planning and infrastructure, with the absurd belief that human beings can live away from the nearest nature.
For example, in the hill Cantueña The municipal government plans to create a great urban park, for which he will destroy the existing ecosystem and with it all of us 
s ecological values \u200b\u200bis ie its rich flora, consisting of 296 plant species so far, among which we must mention its 12 endemic Iberian , such as for example Hippocrepis commutata, Onobrychis Matritensis or galianoi and Scabiosa 5 Ibero-Maghreb endemic among which Retama sphaerocarpa , Cerastium gracile or Biscutella auriculata and 35 local endangered species, such as Rumex roseus , Lavatera cretica or Cistus clusii remain for most this natural space their last refuge in the town, this hill also has certain botanical species biogeographic interest, having a character finícola, accounting for some species, the western limit of its range in the Community of Madrid . should also mention their relict populations of olive and almond trees of great ecological and cultural.
As for the fauna, on this hill take shelter countless species of invertebrates, among which intersects Candidula , snail distribution northern valuable biogeographical to file a relict population in this mountain; various dung beetle species threatened with extinction, and many other species of great ecological interest, among which 25 species of butterflies, 5 of which are endangered species both locally and regionally, being rare and localized species. Among the many species of moths, moth stake largest in Europe, being legally protected. Among vertebrates be mentioned more than 12 species of mammals, 91 species of birds, among which we mention 9 species of diurnal raptors, 3 species of owls and 32 steppe bird species and 7 species of reptiles .
As for the landscape, should be mentioned that in this hill are present habitats listed in the EU Directive 92/43/EEC 21 May, as are the m atorrales halonitrófilos, scrub and preestepicos Thermo-among which are included Retamares and thyme with their associated species, "and subestépicas areas of annual grasses and Thero-Brachipodietea and this priority habitat conservation.
As to Brook Humanejos , the City of Parla is planning its transformation into a linear urban park that will cover their banks, sweeping away this valuable river ecosystem, which has been badly affected with the construction Parla Hospital.
Among the various ecological values \u200b\u200bdisappear, certainly stands bo valuable 
sque riverside, which has a good feedback in some places. This forest is composed of 10 species of native trees, and some other non-native, "planted by the council itself 15 years ago, as part of a poorly planned forest restoration of the stream. Also, the substrate shrub and herbaceous substrate associated with coastal tree has great ecological value due to the specialized ecological niche they occupy, without doubt, the extraordinary variety of species included, and 268 have been counted so far, of which 5 species are endemic to the Iberian and the other 5 are endemic to the Iberian-Maghrebi.
As for the fauna, this stream is home to a rich biodiversity of fauna, with 17 species of mammals, among which include the presence of dispersion phase-Iberian lynx, 121 species bird-of which 15 are diurnal, owls 4, 25 species of waterfowl and 53 species of forest birds , the remainder being present steppe birds in surrounding cultures, 7 species of reptiles, amphibians 5 and 172 invertebrate species identified so far, "most notably his 28 butterfly species and 17 species of moths and counting so far, and some beetles of interest is the endemic and threatened and scarabajo-wasp English or dung beetles. In this channel existed until a few years ago a relict population native crayfish (Austropotamobius pallipes).
Humanejos Brook hosts a number of habitats listed in EU Directive 92/43/EEC of 21 May as r Gone are the muddy banks with Chenopodion rubri Bidention pp and pp, the Constantly flowing Mediterranean rivers Paspalo-Agrostidion, with curtains of Salix and Populus alba, and wet meadows of the Mediterranean tall-Holoschoenion Molinion (rushes).
The ecological value of the stream Humanejos not limited to previous reports, as all riparian groves, brings a number of benefits to be taken into account. Your soto stabilize shorelines, acting effectively against soil erosion, regulating floods. Riparian plants, especially trees attract to the surface with their roots deep groundwater increasing the atmospheric relative humidity, the shadow governing daytime temperature, with slowing winds its lush, sheltering in the coldest days of winter, create an environment very act of land and water for life, being a refuge and breeding area prime wildlife and wild flora, diversify the monotonous landscape of the surrounding agricultural plains , etc. ...
Finally, the celebrated steppes of Avutardera Parla will disappear to be covered by the enormous destruction Technology and Business Park of the PAU-5, which runs for more than five million square meters, currently being awarded 75% of municipal land, reaching 80% at year end.
is obvious that the municipal government exists in Parla only priority is the creation of businesses, forgetting their obligation to conserve the ecosystems and protected and rare species that live in the municipality.
Thus municipal government has ignored all the natural wealth albe 
AnGR these ancient and legendary plains, although they exist in habitats and species high ecological value, as wetlands are seasonal (Mediterranean temporary ponds) and subestépicas areas with grasses and annuals of the Thero-Brachipodietea, these two types of habitat, conservation priority, according to EU Directive 92/43/EEC of May 21 as well as wildlife and botanical taxa of great ecological value.
home These steppes, 14 species of mammals, among which the endemic Iberian hare (Lepus granatensis), the gray shrew (Crocidura russula), or the weasel (Mustela nivalis), among others. Bird species recorded amounted to the 102, which frequent the area for breeding, wintering or feeding areas and migratory path. Among them stand steppe birds as the common calendar (Melonocorypha calendar), the short-toed lark (Calandrella brachydactyla), c ollalba blonde (Oenanthe hispanica), dáurica swallow (Hirundo daurica) , bee-eaters ( Merops apiaster) the southern shrike (Lanius meridionalis), the highly endangered lesser kestrel (Falco naumanni), the peregrine falcon (Falco peregrinus peregrinus), the Montagu's harrier (Circus pygargus ), l echuza (Tyto alba), common owl (Athene noctua), the partridge (Alectoris rufa), the common quail (Coturnix coturnix) the common curlew (Burhinus oedicnemus), the Little Bustard (Tetrax tetrax) or even a small population of great bustards (Otis tarda), trying to settle in their former lands.
Among waterfowl, are referring to species of great ecological value and very representative of the various wetlands scattered across the steppes, some of which are common ampullín z (Trachybaptus ruficollis), the mallard real or mallard (Anas platyrhynchos), gray herons (Ardea cinerea), cattle egret (Bubulcul ibis), the white stork (Ciconia ciconia), marsh harrier (Circus aeruginosus), the common moorhen (Gallinula chloropus), the f ocha (Fulica atra), c common igüeñuela (Himantopus himantopus), Little Ringed Plover (Charadrius dubius), the common lapwing (Vanellus vanellus), the a common rchibebe (Tringa totanus), the largest sandpiper (Tringa ochropus), the Common Sandpiper (Actitis hypoleucos) the gull (Larus fuscus), the l avandera cascadeña (Motacilla cinerea) or Buitrón (Cisticola juncidis), among other species.
In step migration or dispersal phase can be observed in these steppe birds as emblematic as the b Uitra black (Aegypius monachus), griffon vulture (Gyps fulvus), the road to Eagle (Hieraaetus pennatus), the toed (Circaetus gallicus), the Whinchat (Saxicola rubetra), the Tawny Pipit (Anthus campestris), the endemic Iberian pied flycatcher (Ficedula hypoleuca iberiae) and Iberian fly (Phylloscopus ibericus), among others species.
In these steppes live up to 6 species of reptiles, such as l Cinderella agartija (Psammodromus hispanicus) , the lizard (Lacerta lepida) or the ladder snake (Rhinechis scalaris), endemic Iberian-Gallic of great ecological and biogeographical. In the steppe and wetlands of the area are the last 4 species of amphibian populations, globally threatened animal groups, some endemic species such as the Iberian midwife toad (Alytes cisternasii).
reference to the flora of these steppes, it is remarkable the presence of certain weed taxa as Scilla bifolia, taxon only known from the literature in the Madrid area, Iberian endemism Euphorbia Matritensis, Rumex roseus Iberian taxon low dispersed distribution, the Tanacetum microphyllum, interesting taxon introgression from Luso-extremadurense, the Retama sphaerocarpa, Ibero-North African endemic. Grasses and other species of great ecological interest as Spergularia purpurea, Andryala integrifolia, Lupinus angustifolius, Linaria spartea, Globularia vulgaris, Campanula rapunculus, Chrozophora tinctoria etc.
existing seasonal wetlands in these steppe-lakes Barca Sanchez, de la Fuente, the washing of Pajeros, etc., Have a great interest floristic species to exist in them as Lythrum thymifolia, Heliotropium supinum, Verbena supine Myosurus minimus, etc. they are all rare species to inhabit a rare habitat, they appear with other species of great ecological value as Eleocharis palustris vulgaris, Scirpoides holoschoenus, Carex currency Pulicaria paludosa, Ranunculus sceleratus, Glyceria declinata, Typha latifolia, Tamarix canariensis , salviifolia Salix, Salix atrocinerea, taxa also the most uncommon or even some of them endemic to the Iberian peninsula.
