In 90 minutes, 50+ volunteers put in the start of this new area of heavily-shrubbed forest at what used to be the edge of a lawn in Taylor Creek Park:
Rapid butterfly declines across the United States during the 21st century
https://www.science.org/doi/10.1126/science.adp4671
Numerous declines have been documented across insect groups, and the potential consequences of insect losses are dire. Butterflies are the most surveyed insect taxa, yet analyses have been limited in geographic scale or rely on data from a single monitoring program. Using records of 12.6 million individual butterflies from >76,000 surveys across 35 monitoring programs, we characterized overall and species-specific butterfly abundance trends across the contiguous United States. Between 2000 and 2020, total butterfly abundance fell by 22% across the 554 recorded species. Species-level declines were widespread, with 13 times as many species declining as increasing. The prevalence of declines throughout all regions in the United States highlights an urgent need to protect butterflies from further losses.
Rewilding the City

Rewilding aims to reinstate the natural flows and cycles that existed before human intervention. It looks to restore an area of land to its natural uncultivated state – especially the reintroduction of species of wild flora and fauna that have been driven out or exterminated.
Rewilding also aligns with the City of Toronto’s Biodiversity Strategy, which recognizes the intrinsic value of biodiversity and the important ecosystem services that biodiversity provides which are essential for a sustainable and resilient city.
The environmental benefits of rewilding are numerous and interconnected.
In Dublin, the city council reduced mowing and use of pesticides and so 80% of its green spaces are now pollinator friendly.
Abandoned spaces have become successfully rewilded in: Germany, where abandoned lots in Frankfurt, Dessau and Hanover were transformed into wildflower meadows.
New York, where a former railway track has been transformed into a public park; and Nottingham, which restored a central shopping centre into a wetland.
In the city of Harbin, an urban storm water park has been created to filter and store storm water as well as provide habitats and recreational use for residents.
Other cities are beginning to utilise nature-based buildings. For example, Liuzhou Forest City in China began construction in 2020 and will be the world’s first forest city. An estimated 40,000 trees and 1 million plants from over 100 species will cover the facade of all buildings and infrastructure, absorbing around 10,000 tons of carbon dioxide and 57 tons of pollutants per year, while producing about 900 tons of oxygen. The city will be energy self-sufficient (using geothermal and solar power) and will be integrated into the surrounding environment.
