Conservation and Management

The IUCN Red List conservation status of Markham's Storm-Petrel is assessed as Near Threatened. It is estimated to have a large population (over 150,000 individuals), but is currently decreasing due to the destruction of its habitat and a high fledgling mortality resulting from light pollution in the Atacama Desert.

Effects of Human Activity

Habitat Loss and Degradation

Light Pollution

Light pollution is currently the main threat to the species, with several thousand individuals grounded annually. In the city of Arica, Chile, almost 3,000 individuals fall each year, while in the city of Iquique, Chile almost 1,000 individuals fall yearly (43). An industrial complex inside and surrounding the breeding colony of Salar Grande, Chile has the largest impact; accumulating more than 11,000 grounded birds each year. In the city of Antofagasta, Chile, some dozens of individuals fall each year (43).

The effect of vessels' light pollution at sea is unknown.

Breeding Colony Destruction

Although colonies are sited far from human settlement, almost all face anthropogenic disturbances. The significant threats by colony are listed below:

Pampa Chuño, Chile: Powerlines and solar farms (23, 32).

Pampa Chaca, Chile: garbage, military activities, powerlines; is also transected by the main highroad of Chile (R5) (23, 32).

Pampa Camarones, Chile: salt mining, powerlines, and growth of the energy industry (23, 32).

Pampa Tana, Chile: military activities (23, 32).

Pampa Quiuña, Chile: transected by a road (23, 32).

Caleta Buena (also known as Pampa Perdiz), Chile: transected by a road (23, 32).

Salar Grande, Chile: road building and salt mining (23, 32).

Salar de Navidad, Chile: wind farms (23, 32).

Effects of Invasive Species

Information is needed.

Hunting and Trapping

Hunting and trapping are not a threat to the species.

Pesticides and Other Contaminants/Toxics

Most birds have been recorded with human-made debris in their digestive tracts (44).

Collisions with Stationary/Moving Structures or Objects

Birds can collide with powerlines (Gutiérrez et al., unpublished data).

Human/Research Impacts

Offshore threats are poorly studied, but commercial fishing may have some effect on this species (i.e., overexploitation of its food resources).

Management

Conservation Plan

In Chile, the Environmental Ministry, together with the Red de Observadores de Aves y Vida Silvestre de Chile and several stakeholders, generated the first Conservation Plan for the species. This plan included measures to help reduce the species' decline. The actions proposed are:

Breeding Colony Protection

Pampa Chaca is now partially protected by ROC. There are trials for creating a protected area in Salar Caleta Buena. In addition to these protected areas, a management plan could be developed inside military properties to protect the species.

Light Pollution Regulation

In Chile, the Environmental Ministry updated its light pollution norm to reduce light pollution in important areas for biodiversity, including around the breeding colonies of this species. In Salar Grande, some big industries voluntarily agreed to change their illumination system to avoid the massive fallout of fledglings.

Rescue and Release Program

"Rescue and release" programs led by local NGOs and governmental agencies in Tacna, Arica, Iquique, and Antofagasta exist (43); however, it is necessary to assess the survival of released birds.
