For identification of vegetation types:

  • computerised diagnosis of vegetation types;
  • automatically classifies vegetation groups according to the National Vegetation Classification (NVC) - these are described in British plant communities, edited by John Rodwell (Cambridge University Press, 5 vols, published 1991-2000);
  • identifies habitat types according to the EC CORINE system.

TABLEFIT was published in 1993 and rewritten in June 1996, to take account of additional (at that time unpublished) set of association tables for weed communities, mud pioneer vegetation and some other types.

  • TABLEFIT is supplied as a .EXE executable file for MSDOS;
  • You get FORTRAN source code to allow you to run it on other machines;
  • TABLEFIT 1.0 includes, for the first time, information on weed communities;
  • You get a full list of unabbreviated species names;
  • There are supporting programs to allow you to analyse pre-existing datasets;

Development was supported by the Natural Environment Research Council and the Joint Nature Conservation Committee.

What does TABLEFIT do?

TABLEFIT is a computer program for identifying vegetation types by means of an index of goodness-of-fit, which measures the degree of agreement between the sample under study and the association tables in British plant communities (Hill 1989). Vegetation types are graded according to their goodness-of-fit. This allows samples intermediate between two types to be recognised, because they have nearly equal goodness-of-fit to the two types. In addition, various statistics are given, indicating to what extent any failure of fit is a result of species that ought to be present being absent, or because species that are unexpected are present. TABLEFIT also provides a cross-reference to the CORINE system of biotopes (Devillers et al. 1991).

TABLCORN

TABLCORN is a program for converting data from TABLEFIT format to Cornell Condensed Format; the input format for DECORANA and TWINSPAN. This and other supporting programs make data preparation for input to these programs extremely simple. TABLCORN version 1.0 allows better control of species order than the original version supplied with TABLEFIT.
