Aims<\/h3>

With the aim of studying land-use-change patterns of plant covers, information is being compiled on the past vegetation of Sierra Nevada through old aerial photographs (1956). This enables identify singular areas with ecological processes of special interest in the global-change study.<\/p><\/div><\/div><\/div><\/div>

Method and effort<\/h3>

This consists of reinterpreting the most current version of the vegetation map at 1:10,000 over the orthophotography of 1956, reviewing geometry and attributes. With the use of the appropriate GIS edition tools, more than 35,000 polygons are reviewed. All the information generated is combined into a normalized geographic database to be made compatible with other data models (SIOSE and REDIAM). This map makes it possible: to perform diachronic analyses of the plant cover and land uses, as well as to detect ecological processes such as elevational migrations, colonization of degraded habitats, etc.<\/p><\/div><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Periodicity<\/h3>

At present, there are photos of Sierra Nevada of sufficient quality for the dates: 1956, 1977, 1984, 1998, 2001, 2004, 2007, and 2009.<\/p><\/div><\/div><\/div><\/div>
