FARMING ON GRASSLANDS POSES EXTIRPATION RISK TO CROWNED EAGLES

An intensive lobby is underway in the Rio Grande do Sul´s politics fighting for environmental licence to free investors to start huge Pinus and Eucalipto tree farming projects. Theses projects will cover about 500 thousands hectares of pampas grasslands. Such strong lobby leaded by Aracruz, and Votorantim which are intending to start theses huge tree farming projetcs destroying some of the last remaining Crowned Eagles habitats.

The last known open land Crowned Eagles population (Harpyhaliaetus coronatus) in South Brazil may be extirpated within the near future. We have studied and worked to conserve this relict population in Santa Catarina and Rio Grande do Sul for the last four years, and we feel a responsibility to inform the international community of the recent and ongoing destruction of the eagle’s breeding habitat through the tree farming of native grasslands, along with flooding of native forests by hydropower damns.

Crowned Eagles breed in trees in galery forests and gorges now been flooded by damns and hunt in grasslands.

Crowned Eagles´s habitats in Rio Grande do Sul savanas at risk

Pristine savana habitats are now been covered with Eucapypto stands putting Crowned Eagles hunting grounds at risk

Galery forests in Ibirapuitã River in Rio Grande do Sul state

Crowned Eagles nests in large trees in galery forests like his in Ibirapuita River in Rio Grande do Sul State near the border beteween Brazil and Uruguay. Forests like this are becoming rare in south Brazil because land use. More recently a large project of reforestation of the open lands using Eucalypto stands puts in danger the remanining hunting habitats of crowned eagles.

Brazil have laws disigned to protect forested areas, but until now there is nothing aiming the conservation of open lands.

There is no information on the present status of Crowned Eagles in the savana of Rio Grande do Sul States. The present land management plans of Rio Grande do Sul favoring the reforestation of large areas with Pinus or Eucalipto stands puts Crowned Eagles at danger.

PAI QUERÊ DAM IN THE PELOTAS RIVER HEADWATERS THREATENS CROWNED-SOLITARY EAGLES (HARPYHALIATETUS CORONATUS) IN SOUTH BRAZIL

A recent surge in building dams in Pelotas and Uruguai Rivers in South Brazil poses a serious threat to the conservation of Crowned-Solitary Eagles. Pelotas River runs along the border of Rio Grande do Sul and Santa Catarina States in South Brazil. Over 6.000 hectares of pristine Araucária Forests were flooded recently after long and laborious legal battle against BAESA – company owner of the hydropower dam in Anita Garibaldi City.

Crowned-Solitary Eagles are endangered species in Brazil and nest in tall araucaria trees in the Pelotas River gorges. After the flooding of the pristine Araucaria forests along the river, eagles had their breeding habitats compressed by the resulting hydropower lake and Pines plantations in the upper slopes of the Pelotas River.

Recently we recorded 3-4 adult eagles in the area suggesting they are still there. These eagles use the forests along the Pelotas River to breed and rest and the nearby open lands to foraging.

Situation of this eagle is critical once there is another dam (Pai Quere) under process to get environmental license to be constructed. An active and efficient lobby by local and federal politicians is working hard to get environmental license to start Pai Quere Dam construction.

If Pai Querê Dam is approved to be build an large area of Araucaria mixed florets will be flooded putting more negative pressure on the conservation of the endangered Crowned-Solitary Eagle.

Pristine habitat of the Crowned Eagle are threatened by Eucalypto and Pinus farms in South Brazil

Crowned Eagle is one of the most endagered species in Brazil. This eagle is found of open formation where it can hunt. They breed in galery forests along rivers. Large silvicultural projects using Pinus and Eucalyptus are in vogue nowadays in Rio Grande do Sul. Over 400 thousands hectares of the traditional campanha/steppe landscape are planned to replaced by eucalyptus stands. Under this circunstances Crowned Eagles are facing one more threath in Brazil. After most of cerrado and savanas in planalto of Santa Catarina, Paraná, Goias and Mato Grosso were replaced by agroindustry plantations such as soy beans and corn fields, crowned eagloes now are facing another impact on its remaining open habitats in south Brazil.

Pinus and eucaliptus stands by one side and hydropower damms on the other side are the mais threats on the future of this endangered species.
