I'm just starting to work with the software programm ArcGis and want to merge about 20 different rasta files containing the distribution of european tree species. They all have different values related to their distribution level, i want to combine them in one layer but only the dominant species, should be presented, so if there are different species in one grid cell only the one with the highest value should be presented, furthermore I want to make a time-related map, using a simple coefficient, just saying that for example broadleave areas are shrinking since the 1950s.

Best regards and thanks for the help.
