The fiscal impact portion of the study will take nine months to a year, Abraham said. 'We're working on a fiscal analysis right now to determine which plants will go into that, as well as which plants we need to educate the public about,' she said. She expects a few more plants, possibly Callery pear, Norway maple and burning bush, will be added to the list. The current list, which can be found at , will be reviewed in the near future, Abraham said. The regulation is to attempt to minimize the impact invasive plants can have on other plants and wildlife throughout the Hoosier state. The plants on the list are not native and are too aggressive, taking over habitat from native plants. Many of the plants on the list were once desirable, such as Asian bush honeysuckle. Not all plants considered invasive in Indiana are on the list. The law went into effect over the course of several months, and implementation was a slow process. When the terrestrial plant regulation first went into effect state officials educated people at nurseries and garden centers about the changes - before invasive plants were destroyed in most cases.
