“…Ideally, use field information on species' relative abundance at different sites. In some cases, population censuses are available, particularly for congregatory species (e.g., Perez-Arteaga et al 2002). Other sources of information are reporting rates (e.g., Harrison et al 1997); habitat modeling, which may predict abundance in poorly known areas (e.g., Hansen and Rotella 2002); and finally, a qualitative assessment based on the field experience of experts.…”

“…Bearing in mind the extreme pressure on the classification and designation process, both from competing land use options and from the European Union to meet set quotas and targets, this level of protection is a remarkable achievement, particularly in comparison with other countries. For example, the Ramsar network in Mexico has been strongly criticised by Perez-Arteaga, Gaston & Kershaw (2002), who concluded that the seven existing Ramsar sites are not representative of Mexican wetland diversity. Furthermore, the current number of Ramsar Sites officially listed on the 'IUCN Protected areas of the world database' for Great Britain greatly exceeds that of all other signatories (e.g.…”

Protecting systematically selected areas of land is a major step towards biodiversity conservation worldwide. Indeed, the identification and designation of protected areas more often than not forms a core component of both national and international conservation policies. In this paper we provide an overview of those Special Protection Areas and Ramsar Sites that have been classified in Great Britain as of 1998/99 for a selection of wintering waterbird species, using bird count data from the Wetland Bird Survey. The performance of this network of sites is remarkable, particularly in comparison with published analyses of networks elsewhere in the world. Nevertheless, the current site-based approach, whilst having the great benefit of simplicity, is deliberately biased towards aggregating species at the expense of the more dispersed distribution species. To ensure that the network continues successfully to protect nationally and internationally important waterbird populations, efforts now need to concentrate on the derivation of species-specific representation targets and, in particular, the ways in which these can be incorporated into the site selection process. Although these analyses concern the performance of protected areas for waterbirds in Great Britain, the results have wide-ranging importance for conservation planning in general and the design of protected area networks.

“…Across central Mexico, there are numerous unprotected water bodies that qualify as threatened wetland ecosystems under international conventions [40], and large lakes in this study area, including Chapala and Cuitzeo, have seen volumes decline at an unprecedented rate over recent decades [35,41]. Drought events have a major impact on the Mexican agricultural sector and the communities who depend on it [42,43], and the linear patterns of increased drying and decreased precipitation are shaping a variety of industries [44].…”

Distinguishing Land Change from Natural Variability and Uncertainty in Central Mexico with MODIS EVI, TRMM Precipitation, and MODIS LST Data

Precipitation and temperature enact variable influences on vegetation, impacting the type and condition of land cover, as well as the assessment of change over broad landscapes. Separating the influence of vegetative variability independent and discrete land cover change remains a major challenge to landscape change assessments. The heterogeneous Lerma-Chapala-Santiago watershed of central Mexico exemplifies both natural and anthropogenic forces enacting variability and change on the landscape. This study employed a time series of Enhanced Vegetation Index (EVI) composites from the Moderate Resolution Imaging Spectoradiometer (MODIS) for 2001-2007 and per-pixel multiple linear regressions in order to model changes in EVI as a function of precipitation, temperature, and elevation. Over the seven-year period, 59.1% of the variability in EVI was explained by variability in the independent variables, with highest model performance among changing and heterogeneous land cover types, while intact forest cover demonstrated the greatest resistance to changes in temperature and precipitation. Model results were compared to an independent change uncertainty assessment, and selected regional samples of change confusion and natural variability give insight to common problems afflicting land change analyses.
