Finding nature in your city

WildArk.org does a great job of describing where the wild places are in various cities around the globe. Their main mission is to preserve species and ecosystems through education and research. Check out their website at https://wildark.org

Transitional ecologies and tactical urban artists

“We are optimistic that the combination of creativity, ingenuity and low-budget, DIY mindsets that are hallmarks of both ecologists and public artists will help collaborators transform abandoned space into exciting and informative destinations.”

Clean, green cities poised to take shape

China is building high-rise forest towers. Courtesy of China Daily news:

"For example, in Nanjing, capital of Jiangsu province, two residential high-rises designed by Italian architect Stefano Boeri are being built.

When completed, the buildings will house 1,100 trees from 23 local species and 2,500 cascading plants and shrubs, which according to the architects, will absorb 25 metric tons of carbon dioxide each year and produce about 60 kilograms of oxygen a day.

To put that in perspective, removing 25 tons of carbon dioxide would be equivalent to taking five cars off the road for a year. Chinese cities have some of the most polluted air in the world."

Toward an Urban Ecology: SCAPE

Kate Orff, 2017 MacArthur Fellow, has an optimistic and transformative message about our world: we can bring together social and ecological systems to sustainably remake our cities and landscapes. Part monograph, part manual, part manife­sto, Toward an Urban Ecology reconceives urban landscape design as a form of activism, demonstrating how to move beyond familiar and increasingly outmoded ways of thinking about environmental, urban, and social issues as separate domains; and advocating for the synthesis of practice to create a truly urban ecology. 

In purely practical terms, SCAPE has already generated numerous tools and techniques that designers, policy makers, and communities can use to address some of the most pressing issues of our time, including the loss of biodiversity, the loss of social cohesion, and ecological degradation. Toward an Urban Ecology features numerous projects and select research from SCAPE, and conveys a range of strategies to engender a more resilient and inclusive built environment.

Native birds aren't crazy about exotic street tree plantings

"Urbanisation is a leading cause of biodiversity loss and habitat fragmentation internationally, and the conservation of representative native assemblages is a challenge confronting environmental managers in expanding urban landscapes. This study investigates the bird assemblages occurring in a rapidly growing regional centre, Ballarat, southeastern Australia. It aims to examine the relationships between urbanisation and bird communities in a regional city by investigating the differences in bird assemblage composition related to the type of vegetation (native or exotic) in urban streetscapes. Bird surveys were completed across four broad habitat types: remnant vegetation, exotic streetscapes, native streetscapes and newly developed streetscapes. Each habitat type had three 1 ha replicate sites. Results show that remnant vegetation fringing residential areas and native streetscapes supported around 60% more native bird species than exotic and newly developed streetscapes. Avian species composition was significantly different between broad habitat types, with remnant vegetation and native streetscapes maintaining representative native bird assemblages, but exotic streetscapes and newly developed streetscapes were dominated by introduced birds. Our results show that, for representative native bird assemblages to be maintained in urban areas, the maintenance of remnant and native vegetation is essential."
