New rewilding web site throughout the Larger Coa Valley improves connectivity

A newly established rewilding web site in northern Portugal, often known as Ermo das Águias (‘wilderness of the eagles’), is offering a possibility to enhance panorama connectivity and promote the regeneration of native vegetation and improve the advantages of pure grazing.

The wealthy biodiversity of the Ermo das Águias has been boosted by the introduction of native Sorraia horses to create mosaics within the panorama.

Enhancing connectivity

The brand new web site Ermo das Águias will open to the general public in June, with a community of marked trails exploring the world. Funded by the Endangered Landscapes Programme, the 700 hectares of land within the parish of Vale de Madeira established the second in a collection of core rewilding websites alongside the course of the Côa River. The primary space – Vale Carapito – was established in 2021.

Each areas are a part of a 120,000-hectare wildlife hall being developed to attach the Malcata mountain vary within the south with the bigger Douro Valley within the north. “The aim,” says Marta Cálix, Head of Operations at Rewilding Portugal, “is to amass and rewild items of land throughout the panorama to enhance connectivity and to guard these areas which might be nonetheless in higher situation or have essentially the most potential by way of ecological restoration and defending organic variety.”

Creating pure firebreaks

Ermo das Águias has been boosted by the introduction of native Sorraia horses to create mosaics within the panorama, demonstrating the advantages of pure grazing for rising biodiversity and reducing the chance of wildfire.

Hearth has at all times been a pure course of within the Larger Côa Valley panorama, however in recent times Portugal has suffered an unprecedented surge within the frequency of wildfires, inhibiting the restoration of native vegetation, eroding the seedbank and threatening human lives.

“On this explicit space, over the previous 10 years, the land has burned on common each 2.7 years,” explains Marta. “So, considered one of our key goals is to scale back the frequency of fires, to permit pure vegetational succession to happen.”

Climatic modifications are resulting in a higher variety of scorching and windy days that create the right situations for wildfires to unfold rapidly and burn massive areas. Moderately than occurring at intervals of many years, intense wildfires now scorch this panorama each couple of years. Hearth surveillance may also help to intercept these blazes earlier than they get uncontrolled, however the perfect defenses are pure firebreaks, and that is the place nature stands able to help.


Pure reinforcements

The chance and frequency of damaging wildfires have been exacerbated by a scarcity of enormous wild herbivores. The Sorraia horses are creating pure firebreaks by grazing down lengthy grasses, lowering gasoline masses, and trampling down the flammable thickets of tinder-dry broom, releasing the local people from dependence on costly and labour-intensive mechanical interventions.

“These horses, what they do is – they eat, and so they trample, and so they create mosaics within the panorama, in order that they preserve grasslands that are an necessary a part of native biodiversity, however which additionally create pure firebreaks,” explains Marta.

With fewer, much less intense fires and the extra contribution of Sorraia horses dispersing seeds throughout this recovering panorama, forests right here can have an opportunity to broaden and mature, casting cooling shade and restoring the complicated net of woodland life.

The native Sorraia horse are completely tailored to thrive on this harsh panorama. Eight females and a juvenile male have been launched, with plans in place to quickly introduce a breeding stallion to the younger herd. The concept is to begin small, so the carrying capability of the land is just not reached too quickly, however over time, because the herd grows, the hope is that these powerful trailblazers will produce descendants that may be dispersed across the Larger Côa Valley.

Sorraias are a uncommon and historic breed, indigenous to the Iberian Peninsula, however which now quantity just a few hundred animals, as much less ‘primitive’ breeds have turn out to be extra well-liked. Curiously, the Sorraia horse might be a survivor of a wild equine which within the Center Ages was known as ‘zebro’. Sorraia foals nonetheless retain the stripes which characterised the unique zebro, stripes which can have impressed Portuguese explorers to offer African wild equids the identify ‘zebras’.

In the present day, the introduction of Sorraia horses to Ermo das Águias supplies a possibility to safeguard the way forward for these particular animals and to re-establish their lacking function inside this ecosystem.

Stepping stones

The institution of the Sorraia horses is barely the start. “As soon as we get used to managing these horses, we’re contemplating bringing the primary herd of Tauros to Portugal”, enthuses Marta. Simply as Ermo das Águias is serving as a stepping stone to extend connectivity alongside the Côa River, the Sorraia horses look like serving as a stepping stone in direction of the re-establishment of a wilder, extra resilient regional ecosystem.

Equally importantly maybe, charismatic animals just like the Sorraia horses and the Tauros assist encourage delight within the Côa Valley’s exceptional pure heritage, creating contemporary appreciation for the hovering eagles and vultures, and inspiring tolerance for returning wolves. Native individuals are accustomed to celebrating the world’s wealthy historic and cultural traditions however didn’t at all times admire the equally wealthy pure heritage they’re accountable for. And on a sensible degree, the seen outcomes of the Sorraia reintroduction – lowering wildfires and boosting tourism – assist construct very important belief within the Rewilding course of, respiration life again into this recovering panorama and securing a extra sustainable future for everybody.


The event of tourism within the space will assist native communities to thrive.
