Campo Iris Nature Reserve
Saving the Paraguayan Dry Chaco
The World Land Trust has funded a reserve in Paraguay's Dry Chaco (dry savanna grassland) to protect rare mammals and raise awareness of the diversity of wildlife and the threats to the habitat.
The Dry Chaco is part of a larger eco-region known as the Gran Chaco, which translates in the Quechua language as ‘productive hunting grounds’. As this name suggests, this confluence of unique habitats supports a large variety of wildlife, including many mammal species.
The Dry Chaco is an arid habitat of highly impenetrable forest, including thorn bushes and a large number of different cacti, all especially adapted to the dry conditions.
Whilst much attention has been placed on the tropical forests of South America, the Chaco, in the very heart of the continent, has been largely overlooked, yet it is home to a diverse range of wildlife, with more large mammals than the Amazon Forest, including Puma, Lowland Tapir, Giant Anteater and the worlds greatest diversity of armadillos.
This area is true wilderness and it was not until 1975 that the Chaco Peccary, the largest of the Peccary species, was discovered, having previously only been known from fossil records.
The Dry Chaco is also one of the few places where there are still isolated groups of indigenous Ayoreo people who have never had contact with the outside world. WLT is working to protect habitat for both wildlife and people, as this region is important for both the local Ayoreo and Guarani-ñandeva people.
Campo Iris Nature Reserve
Working with local partners Guyra Paraguay, WLT began fundraising for the purchase of the Campo Iris Nature Reserve in 2007.
Campo Iris encompasses over 8,500 acres of typical Dry Chaco habitat, and is essential to protect as it contains the only temporal lagoon in a wide area, making it a vital resource for the local wildlife, which come to drink in the reserve.
In early 2009 Campo Iris received official recognition from the Paraguayan Government, giving it the status of a Private Nature Reserve and the local municipality also recognised the Reserve's importance for conservation. Campo Iris will be permanently protected by WLT project partners Guyra Paraguay. However, the Campo Iris Nature Reserve covers a very small area when compared to the size of the vast Dry Chaco. WLT is continuing to support the management of Campo Iris and, at the same time, is urgently raising funds to extend this reserve in order to safeguard more of this habitat for wildlife.
In addition to large mammals such as the Lowland Tapir, which can be seen visiting the Campo Iris lagoon, the Chaco has a number of species found nowhere else in the world. This includes endemic species such as Chaco Guanaco, the Chaco Tortoise, as well as the Chaco Peccary, which was only rediscovered in 1975.
Over 100 species of reptiles have been recorded here, as well as many bird species, including the endangered Crowned Solitary Eagle, Greater Rhea, Chaco Chacalaca, Chaco Blue-fronted Amazon, Guira Cuckoo and Brushland Tinamou.
Another key species of the Chaco is the distinctive Palo Borracho (Ceiba chodatii), as seen in the photo. The species is also known as the 'Drunken Tree' due to its swollen trunk which is adapted to retain water in the arid Chaco habitat.
