  1. AN INFORMATION SYSTEM FOR VEGETATION MANAGEMENT Jesus M. Muñoz Álvarez et al. e-mail: bv1mualj@uco.es Naples, junio 2003

  2. 1. To looke at some actual graphical and numerical results What? 2. Methodology How? 3. To set these studies in the framework of Environmental Information Management in Andalusia Why?

  3. WHAT?

  4. AUTONOMOUS REGION OF ANDALUSIA Area of Andalusia: 87. 600 Km2

  5. Natural Park Sierra Pelada and Rivera del Aserrador (Huelva)

  6. Natural Park of Despeñaperros (Jaén)

  7. Sierra Pelada and Rivera del Aserrador Actual Real Vegetation (ARV)

  8. Sierra Pelada and Rivera del Aserrador

  9. Sierra Pelada and Rivera del Aserrador

  10. Sierra Pelada and Rivera del Aserrador Potential Natural Vegetation (PNV)

  11. Sierra Pelada and Rivera del Aserrador Actual Real Vegetation (ARV) Tree Cover

  12. Sierra Pelada and Rivera del Aserrador Actual Real Vegetation (ARV) Shrubland and tree cover

  13. Despeñaperros

  14. Despeñaperros

  15. Despeñaperros Arbuto unedonis –Quercetum pyrenaicae

  16. Despeñaperros

  17. Despeñaperros

  18. HOW?

  19. Methodology: phases 1. Photointerpretation 2. Map restitution 3. Field vegetation data collection 4. Coding and storage of information in databases

  20. 1. Photointerpretation

  21. 1. Photointerpretation

  22. 1. PHOTOINTERPRETATION 0 Bare soil and rock 1 Woodlands 2 Preforest shrubland 3 Serial shrubland 4 Pastureland 5 Gallery forest 6 Riparian shrubland 7 Forestry plantations 8 Woody crops 9 Herbaceous crops E Reservoirs NC Urban settlements CF Firebreaks C Farms and similar buildings A Ponds n > 75 % i 50-75 % p 25-50 % r 5-25 %

  23. 2. MAP RESTITUTION

  24. 2. MAP RESTITUTION

  25. 2. MAP RESTITUTION • Result: • A preliminary graphic cover in digital format.

  26. 3. FIELD VEGETATION DATA COLLECTION Sampling methods • Relevés of natural and some seminatural communities • Random line transects • Random quadrats for frequency determination

  27. 3. FIELD VEGETATION DATA COLLECTION And moreover... • Direct recording of species or communities on acetates • Records-cards

  28. Also is collected information on: • Environmental variables (elevation, aspect, slope, lithology) • Potential Natural Vegetation (PNV) • Bioclimatic belt • Contacts in space between communities. 3. FIELD VEGETATION DATA COLLECTION

  29. 3. FIELD VEGETATION DATA COLLECTION Finally: Corrections to polygons borders or polygon identification are made directly on the photos

  30. 4. CODING AND STORAGE OF INFORMATION IN DATABASES 4.1 Coding process 1. A number is assigned to each polygon: the mapping unit

  31. Structural • Floristic • Bioclimatic and biogeographical • Potential vegetation • Other information: type of land use and type of forets fuel, if present 4. CODING AND STORAGE OF INFORMATION IN DATABASES 4.1 Coding process 2. Different types of information are associated with that number:

  32. 4. CODING AND STORAGE OF INFORMATION IN DATABASES 4.1 Coding process • This means: • that those polygons for which this data set is exactly the same, have the same code and the same type of coding unit, or • the variation of a single datum, for example the degree of tree cover, generates a new mapping unit, and a new code

  33. RELACIONES ESTABLECIDAS PARA ASOCIAR LA INFORMACIÓN GRÁFICA A LA INFORMACIÓN DE TIPO FÍSICO Y BIOLÓGICO. RELACIONES ESTABLECIDAS PARA LA OBTENCIÓN DE DATOS DE TIPO BIOLÓGICO 4. CODING AND STORAGE OF INFORMATION IN DATABASES 4.2 Databases structure RELACIONES ESTABLECIDAS PARA LA OBTENCIÓN DE DATOS DE TIPO FÍSICO.

  36. Methodology • Main results: • Graphical information in digital format. • Alphanumeric information in a total of 19 tables

  37. Despeñaperros Polygons cover

  38. Despeñaperros Sampling points cover

  39. WHY?

  40. Andalusian Environmental Information Network (Regional Council Environment Department) Original aim: to make available to the politicians responsible the basic information for the taking of correct decisions on environmental issues Main aim today: to constitute a permanent Environmental Information System to provide the public at large, and scientists, technicians and managers, with a tool geared towards achieving a better environment

  41. AIMS OF VEGETATION MAPPING ON A DETAILED SCALE (1:10.000) IN NPA 1. To evaluate the floristic and phytocenotic importance of NPA in Andalusia 2. To define and identify habitats of community importance, as specified in the Habitats Directive 92/43/EEC 3. To pinpoint the location of plant species of particular interest, as per Habitats Directive 92/43/EEC and in accordance with the Andalusian Catalogue of Threatened Wild Flora 4. To serve as a basis for modelling animal-sustaining capacity, risk prevention and simulation –forest fires, erosion and so on...- 5. To serve as a source of basic information for assesing the impact of any action taken in a NPA on habitats or threatened plant species

  42. Andalusian Environmental Information Network Main functions • Provision of Environmental Information on Andalusia, using new technologies linked to the Geographic Information Sistem (GIS) and to Teledetection System, for example: • Creation and maintenance of a spatial reference database at recognition, semidetailed and detailed scale • Creation of thematic environmental maps • Creation of networks of measurements of environmental variables • Development of rules and instructions for uniform drafting of environmental information

  43. Andalusian Environmental Information Network Main functions 2. Maintenance and updating of the Environmental Management Information System 3. Development of mechanisms for Institutional Coordination with other national and international bodies

  44. Andalusian Environmental Information Network BASIC INFORMATIC MANAGEMENT TOOLS • Include a range of computer-based supports to facilitate the inclusion of projects in the system: • Oracle is used for databases • ArcInfo for vector information • And for raster information (Amatel), management of projects, coding dictionaries, and so on.
