The Dynamic Habitat Index (DHI) comprises of three indicators of the underlying vegetation dynamics derived from an annual sequence of MODIS monthly fPAR: (i) the cumulative annual greenness, (ii) the minimum level of perennial cover, and (iii) the degree of vegetation seasonality. The fPAR components were first computed for the years 2000-2005 and were then averaged to produce a long-term index of each component. The dataset is currently being used in conjunction with other datasets to help characterize ecosystem properties and biodiversity within the Canadian Boreal region (Brandt, 2009).
