This dataset describes the colonization dynamics of 8 introduced species + 1 hybrid complex of salmonids in the subAntarctic Kerguelen islands. It is composed of 1 matrix of presence-absence in space (rivers) and time (years) for each species. River names have been associated to SANDRE / COLISA codes (COLISA is a CRB from IR RARE).
The format is an excel file with multpile sheets, with one sheet describing river data, one sheet describing species data, and all other sheets being species-specific colonization matrices (space X time).
