AbstractInvasive plants may dramatically impact forest ecosystems by establishing dense populations and suppressing the recruitment of native tree species. One invasive shrub currently spreading throughout eastern deciduous forests of North America, Japanese barberry (Berberis thunbergii DC), may be limiting tree recruitment in stands where it invades. Once established, B. thunbergii becomes densely populated within forest understories and suppresses native plants by competing for limited resources, altering soil conditions, and changing the understory microclimate. To quantify native seedling inhibition caused by B. thunbergii invasion, we conducted an observational study on seedling abundance within forest plots that were either invaded or not invaded by B. thunbergii and used survey data to generate Bayesian models of native seedling densities along gradients of increasing B. thunbergii stem counts and aboveground plant dry mass. Model outputs predicted that B. thunbergii–invaded plots had 82% lower seedling densities compared with uninvaded plots. Native tree seedling densities were very low even in areas with moderate B. thunbergii density, suggesting that reduced tree seedling densities are observed even at low densities of invasion. Our findings indicate that forests invaded with B. thunbergii harbor substantially lower densities of native tree seedlings, with potentially significant long-term consequences for forest ecological integrity, biodiversity, and ecosystem services.

Abstract Non-native, invasive plants can impact birds by altering food sources, nesting substrates and other critical resources. Japanese barberry (Berberis thunbergii) is one of the most invasive, non-native woody plants in in the northeastern USA, and yet almost nothing is known about its effects on birds or other wildlife. To investigate individual-level impacts of Japanese barberry on a forest-breeding bird, we compared food abundance (leaf-litter arthropod biomass) and the physiological condition of territorial male ovenbirds (Seiurus aurocapilla) between areas of a forest preserve in New York State that had high or low densities of Japanese barberry. We used haemoglobin and plasma triglyceride concentrations to indicate energetic condition, plasma uric acid and total plasma protein levels to indicate diet quality, and heterophil to lymphocyte ratios to indicate chronic stress. We found no difference in arthropod biomass between ovenbird territories that were heavily invaded by or relatively free of Japanese barberry. Perhaps largely as a result, we found no relationship between Japanese barberry density and any of our five haematological condition indices. There was also no difference in body mass, body size or age ratio between ovenbirds nesting in areas with low or high densities of Japanese barberry to suggest that relatively uninvaded forest patches were in greater demand and acquired by the most dominant individuals. Our results indicate that Japanese barberry does not reduce habitat quality for breeding male ovenbirds in a way that affects their prey abundance or physiological condition, but we caution that other species of birds and other aspects of habitat quality could be affected differently. We encourage future research on additional bird species and the effects of Japanese barberry on factors such as diet composition, pairing and nesting success and post-fledging survival to improve science-based decision-making about the extent to which conservation resources should be applied towards Japanese barberry control.

Forest Preserve

In 1916, the Forest Preserve District of Cook County began acquiring land to create a natural retreat for Chicagoans in that booming metropolitan region. Since district officials acquired many properties along county streams, water pollution soon interfered with their mission of creating an urban wilderness for recreational pleasure. To address the problem, in 1931, county leaders appointed the Clean Streams Advisory Committee that collaborated with forest preserve staff members to pressure polluters to clean-up their operations and to persuade enforcement agencies to prosecute ongoing offenders. They also lobbied the Public Works Administration to earmark New Deal funding for sewage treatment in Cook County. Their efforts suggest that early activism against water pollution in American cities emerged not only from efforts to ensure clean drinking water, but also struggles to protect nature. The interwar campaign to clean forest preserve streams anticipated the goals of the federal Clean Water Act (1972) to make all American waterways fishable and swimmable. The movement also preceded the burst of anti-pollution activism that historians have documented in U.S. suburbs after WWII and laid the groundwork for postwar efforts to mitigate water pollution in Cook County.

Deadly Disease

During early 2020, the world encountered an extreme event in the form of a new and deadly disease, COVID-19. Over the next two years, the pandemic brought sickness and death to countries and their cities around the globe. One of the first and initially the hardest hit location was New York City, USA. This article is an introduction to the Special Issue in this journal that highlights the impacts from and responses to COVID-19 as an extreme event in the New York City metropolitan region. We overview the aspects of COVID-19 that make it an important global extreme event, provide brief background to the conditions in the world, and the US before describing the 10 articles in the issue that focus on conditions, events and dynamics in New York City during the initial phases of the pandemic.

AbstractIt is five years since Hurricane Sandy heavily damaged the New York- New Jersey Metropolitan region, and the fuller character of the long-term response can be better understood. The long-term response to Hurricane Sandy and the flooding risks it illustrated are set in myriad of individual and collective decisions taken during the time following the event. While the physical vulnerability of this region to storm surge flooding and climate change risks including sea level rise has been well-documented within the scholarly literature, Sandy’s impact placed decision-makingpost extreme events into the forefront of public and private discussions about the appropriate response. Some of the most fundamental choices were made by individual homeowners who houses were damaged and in some cases made uninhabitable following the storm. These individuals were forced to make decisions regarding where they would live and whether Sandy’s impact would result in their moving. In the disaster recovery and rebuilding context, these early household struggles about whether to leave or stay are often lost in the wider and longer narrative of recovery. To examine this early phase, this paper presents results of a research study that documented the ephemeral evidence of the initial phase of recovery in coastal communities that were heavily impacted by Hurricane Sandy’s storm surge and flooding. Hurricane Sandy and the immediate response to the storm created conditions for a potential large-scale transformation with respect to settlement of the coastal zone. In the paper, we examine and analyze survey and interview results of sixty-one residents and two dozen local stakeholders and practitioners to understand the stresses and transitions experienced by flooded households and the implications for the longer term resiliency of the communities in which they are located.
