The Arrow is a unique natural paradise because of its annual growth and constant changes in shape, especially in the tip, they do not see the same peninsula two consecutive years.

Nevertheless, this is not the only thing that makes it special. We show seven curiosities that probably will not know… until now.

1. Almost the quarter is under water at high tide
Active Tidal Influence Zone occupies approximately 23% the Arrow, divided between incoming tide, marisma, intertidal zone and inner pipes. Although there is always lagoons where water, most of the areas covered by the high tide are obvious when this low.

Tidal starters are distributed throughout the northern facade of the Arrow, that is to say, the bank overlooking the river Piedras, but they are interrupted in the area of ​​the Casa del Palo and next to Real de Almadraba New Umbria. Marshes, instead, They are grouped into four areas, most of them being located near the tip of the arrow.

2. It does not exist 200 yearsARROW
This may be the probably most shocking thing, but it explains some of which we will enunciate later.

The truth is, although there were barrier islands off the coast since Roman times, it was not until early the S. XIX when they start to join the continent and each other, creating the Arrow as we know it today. The Lisbon earthquake 1755 He had a special role as a trigger for further development of the Arrow, since it altered the whole west coast onubense.

3. They lived there about a thousand people
In the years of activity Almadraba New Umbria, they came to live in the real two hundred tuna fishermen with their families, reaching a population of nearly one thousand from February to September, during the season.

Real Almadraba New Umbria was a town built in front of the Rompido and leaving only ruins and. It has been recently declared of cultural interest, largely thanks to the efforts of John M. Ruiz Acevedo.

dsc00354. Live in it 15 exotic plant species
Of the 189 plant species growing in the Arrow, 15 They are exotic, representing the 8% of the total. those species that are not native to the area are considered exotic, without coming from somewhere specific. Nevertheless, most come from America and southern Africa, but it stresses the presence, although poor, eucalyptus, from Australia.

Other exotic species that have grown in Flecha are the Opuntia tuna and Carpobrotus edulis, known by locals as "Las Tunas" and "crybaby", respectively.

5. He harbored a mixed school
Work in the Real de la Almadraba was incessant for tuna fishermen, but there was also a relentless social life in those barracks.

A small room with a toilet at the bottom to school for children, who sat on separate seats. Nevertheless, not all children could go to learn to read and write, since there was a quota for space reasons. further, mariscando helped older or doing housework, as they were boys or girls.

The absence of grounds around the school facilitated the escape of some school, although faced caning as a punishment the next day go out and play instead of listening lessons.

6. Is moving dunesDunas
A century ago, most of the Arrow lacked vegetation and consisted of moving dunes under the effects of wind. Nowadays, Nevertheless, only 4,3% the Arrow are mobile areas, since the gorse has helped consolidate much of the ground.

Prior to the appearance and subsequent expansion of the population of white broom, large sand dunes occupied the whole extent of the Arrow, and it is also very sensitive to the wind. Morphological variability Natural Park was such a report 1913 notes that a dune 12 meters was too close to a police station, threatening to bury under the sand.

7. It is home to protected species
Although the Nature Reserve is quite rich in flora and fauna despite his youth, it found refuge fleshy species such as thyme and common chameleon.

The passage of people inland areas of the Arrow in the birth endangers the population of pulpy thyme, hence only highly cross the runways that cross from north to south is recommended. The common chameleon, although it is the star of the Natural Park, is not seen so easily because of their camouflage, While many locals have ever met one of these friendly reptiles completely harmless to humans.
