Description: Oak declines are complex disease syndromes and consist of
        many visual indicators that include aspects of tree size, crown
        condition and trunk condition. This can cause difficulty in the
        manual classification of symptomatic and non-symptomatic trees
        from what is in reality a broad spectrum of oak tree health
        condition. Two phenotypic oak decline indexes have been
        developed to quantitatively describe and differentiate oak
        decline syndromes in Quercus robur. This package provides a
        toolkit to generate these decline indexes from phenotypic
        descriptors using the machine learning algorithm random forest.
        The methodology for generating these indexes is outlined in
        Finch et al. (2021) <doi:10.1016/j.foreco.2021.118948>.
