Plant diversity in urban green spaces led to sevenfold increase in insect species New research suggests that the introduction of even small green urban spaces can dramatically improve local biodiversity. A study lead by Dr Luis Mata of the University of Melbourne and Cesar Australia examined the ecological outcomes of planting 12 indigenous plant species on a small 195 square metre plot in Melbourne, adjacent to a major road. The research, Mata told The Guardian, “Was conducted in a very densely urbanised area, completely surrounded by streets and relatively tall buildings, and with limited access to surrounding green space.” The researchers identified the presence of 94 insect species, with 91 indigenous to the Australian state of Victoria. They estimated that by the final year of the study there were about …

New research: planting trees in cities could save lives New research from the Barcelona Institute for Global Health suggests planting more trees could lead to fewer deaths from increasingly high summer temperatures in cities. The researchers say increasing urban tree coverage to 30% could reduce temperatures by approximately 0.4%, which could reduce heat-related deaths by 39.5% according to the study’s modelling. Lead author, Tamara Iungman, says, “We already know that high temperatures in urban environments are associated with negative health outcomes, such as cardiorespiratory failure, hospital admission, and premature death.” Her team wants to influence policymakers to make cities greener, “more sustainable, resilient and healthy.” Co-author Mark Nieuwenhuijsen says, “Planting more trees in cities should be prioritised because it brings a huge range of health benefits beyond reducing heat-related deaths, …

Wanted, A New Public Space for Melbourne: The Future Park International Design Competition invites entrants to propose a new signature space for the city’s centre. The contest is organised by AILA and the University of Melbourne, with up to $20,000 in prize money to be allocated. Participants are challenged to think about how parks shape Melbourne’s urban form, and uncover new possibilities. Restricted to a 10km radius from Melbourne’s city centre, designers are asked to present a rationale for the location of the proposed space and consider how their design responds to challenges facing the city in the 21st century, including climate change, growing population, biodiversity and community. University of Melbourne senior lecturer in Landscape Architecture Jillian Walliss says the competition aims to enhance the role of landscape architecture in …

Emails to Melbourne’s Trees are Romantic, Funny and Strange: The city gave 70,000 trees email addresses for the public to report issues. Instead, they sent love letters and existential queries. Since the project began more than 4,000 emails have come from all over the world including from Russia, Germany, Britain, Hungary, Moldova, Singapore, Brazil, Denmark, Hong Kong and the US. A selection of the emails can be found on the ABC website, including this example: Dear Smooth-barked Apple Myrtle, I am your biggest admirer. I have always wanted to meet you, but tragically, I’m stuck in New York. I think you are the most handsome tree of them all, tall with an inviting open canopy. I love to just dream of you, the smell of your clusters of white flowers, the sight of your …
