Description:

Abstract:

Originally conceptualized as "conversion to pasture", this threat layer was renamed to "grazing pressure" to recognize that the input data does not reflect the threat of conversion but more the direct effect that grazing might have on natural ecosystems. The input data is derived from the FAO Atlas of Livestock, and consists of surfaces of livestock density for: Cattle, Sheep, Goats.

Each livestock type was modeled separately, and due to skewedness in the input data were subjected to one round of normalization using the natural logarithm. Each layer was then fed into the threat analysis model, using the same ecosystem response curves and magnitudes for each livestock type, and combined with equal weighting to produce a final adjusted threat layer for grazing pressure.

Purpose:

To represent geographically severity and scope of the threat upon the conservation of biodiversity in South America

Supplemental_Information:

The SACR science team has been tasked to develop a continental threat assessment to complement the continental priorities assessment that was completed last year. Threat datasets will be used by SACR to refine ecoregional priorities so that they are based on actual threats, inform threat abatement and conservation strategies of the SACR Conservation Programs, and form the basis of an early warning system for major threats to biodiversity that may occur and for which we would need to prepare abatement strategies. Assessing and monitoring threats to the biodiversity in South America is a task composed of different components that can be summarized as follows: Design and create an information system capable of spatially representing the geographic distribution of threats. Model the severity and scope of these threats to provide information about how biodiversity targets (ecosystems) are altered, deteriorated or lost. Create an early warning (biodiversity risk) information system that is capable of providing updated information on predicted tendencies for threats (i.e.; past and current threat data will be used in conjunction with threat forecasting models).
