This report is the third and final report in the Ecological Regeneration Options (ERO) project series. Its purpose is to assist in developing integrated assessment methodologies for evaluating ecological regeneration options in the Avon-Ōtākaro Red Zone (AORZ). This is an important topic to ensure that their potential benefits are recognised alongside those of alternative land uses. This report complements the previous two reports in the ERO series. These provide information on floodplain restoration principles (Orchard, 2017) and an assessment of restoration opportunities in the AORZ using a local knowledge approach (Orchard et al., 2017).The focus of this report is on facilitating robust assessments of the ecological regeneration options presented by the AORZ. A specific objective was to develop an integrated assessment framework to support comparison of those options against each other and against alternative land uses. First, the topics of river corridor evaluation and integrated assessment are briefly introduced and examples of integrated assessment in relevant planning contexts identified. A framework for the integrated assessment of ecological regeneration options is then presented.

Dogwood anthracnose, caused by Discula destructiva (1), is another new catastrophic tree disease that has ravaged natural populations of the flowering dogwood (Cornus florida) in the Appalachians over the past 15 years, and the epidemic is prognosticated to continue (2). An estimated 9.5 million acres have been affected, primarily in the Appalachian Mountains, from VA southwards, alone, and an estimated 50% of all dogwoods in PA have been killed. Since acid deposition has been linked experimentally with disease induction, and since the disease incidence and severity are more pronounced at higher elevations where lower pH precipitation events occur, we investigated the effect of acidic foliar sprays on moiphologic changes in the foliar cuticle and trichomes (3), the initial sites of infection and foci of Discula sporulation.
