This article, written by Special Publications Editor Adam Wilson, contains highlights of paper SPE 165632, "Validation of a Biological-Monitoring Design in Highly Diverse Tropical Forests," by K. Caro, E. Enriquez, E. Juscamayta, E. Oyague, and J. Cabrera, Knight Piesold, and C. Chung, C. Ahumada, A. Watson, and C. Videla, Repsol, prepared for the 2013 SPE Latin American and Caribbean Health, Safety, Social Responsibility, and Environment Conference, Lima, Peru, 26-27 June. The paper has not been peer reviewed.
Biological-monitoring programs provide data for decision making and to ensure the protection of resources. However, in tropical ecosystems that are home to most of the planet’s biodiversity, these programs need to be improved in design and implementation. Block 57 in the Amazon rain forest of southern Peru is an ecosystem with limited information. A systematic biological-monitoring program was designed on the basis of a gradient of disturbance caused by clearing an area.
Oil exploration in Block 57 involves clearing small forest areas during installation of drilling platforms. One of the consequences of this clearing is an increase of edges and the presence of habitats with early successional stages. An edge is defined as a transition zone between two adjacent ecosystems or vegetation communities. In these edges, deleterious effects may be generated.
A biological-monitoring plan has been designed as part of an environmental- management plan to understand the effect that the changes in the habitat associated with the exploratory wells within the primary cloud forests have on the abundance, richness, and diversity of the local flora and fauna.
Block 57 is on the southern Amazon plain and the first foothills of the eastern slope of the Peruvian tropical Andes Mountains (Fig. 1). This is one of the areas with the greatest precipitation and highest temperatures and relative humidity in Peru. At several locations, total annual precipitation exceeds 3000 mm. Relative humidity exceeds 90% in the mornings, and temperatures commonly exceed 37°C in the afternoons during the dry season when the sky is clear.
The study area is in the buffer zones of the Otishi National Park and the Ashaninka and Machiguenga Community Reserves. It is predominantly hilly, with mountainous areas in the western sector and terrace areas near the Tambo and Urubamba rivers. Floral composition in the study area is very heterogeneous with different densities. Palm trees are another representative and varied group in these forests, sometimes rising above the canopy.
The work design includes three platforms in Block 57—Kinteroni BX, Mapi LX, and Mashira GX. This study includes the results of monitoring conducted on the surroundings of the Kinteroni BX exploration platform, also known as Sagari (Fig. 2).
