The interior of Liberty State Park is a heavy-metal contaminated brownfield that contains a novel ecosystem, predominantly composed of grey birch forest. In October 2012, Superstorm Sandy made landfall in the region and brought heavy winds, rain, and saltwater flooding from storm surge. This was the first time that the birch forest was subject to the stress of saltwater flooding.To understand the results of this extreme ecosystem disturbance, the growth rates of birch trees were measured with tree core samples for the years before and after Sandy. The aggregate growth rates before and after Sandy were found to be significantly different, with the post-Sandy growth rates significantly lower. Linear regression indicated an overall decrease in growth rates across all sites over time, including pre-Sandy data. On two sites, the polynomial regression was also significant, and indicated that growth rates may begin increasing. These results are important because they directly conflict with previous hypothesis that the birch forest had entered an alternative steady state of succession. It now appears that the birches are declining and that there may be another successional stage on the horizon.Based on these results, an adaptive management scheme was proposed whereby biodiversity across the entirety of the LSP interior will be increased. Abiotic conditions will be improved through soil amendments and biotic conditions will be amended through seed dispersal. Plant species for seed dispersal were identified and selected based on their contribution to aesthetic value, ecosystem function value, and resilience value.Distributing seeds, rather than specifically planting plants in exact locations, will enable plant species and communities to establish in locations to which they are most suited. Ideally, this will increase biodiversity and therefore increase the resilience of the ecosystem as a whole. the LSP interior is projected to face further stressors and climatic changes in the future and increasing the species pool will help the ecosystem adapt to these changes. Soil amendments will similarly improve conditions to enable plants to self-establish. Additionally, this is not a deterministic strategy, so the ethos of the fourth-nature ecosystem will remain intact. Finally, this management strategy is easily integrated with proposals for public access to the site if they are implemented, but it is also viable if public access remains restricted.Overall, the adaptive management strategy of appropriate seed distribution and soil amendment will improve the ecosystem function of the LSP interior and increase its chance for a functional and resilient future.
