Protecting and enhancing biodiversity in urban areas is critical for meeting international conservation commitments, has a vital role to play the health wellbeing of city residents. Yet, urbanisation can have devastating impacts on biodiversity, with development typically delivering landscapes which habitat remains only as small, fragmented patches, surrounded by an inhospitable matrix. As cities begin plan alongside other land use considerations, planners leverage ecological knowledge planning concepts aid decision making deliver benefits nature people. Here we demonstrate how targeted green infrastructure placement potentially increase delivery landscape level improving connectivity native species. We measure change when parking spaces are converted small across City Melbourne, Australia. test three reallocation scenarios varying levels space conversion spatial prioritisation connectivity. While scenario that maximised number performed best, show greening delivered strongest outcomes per unit area converted. Improvements were two times higher effort was towards locations identified important barriers landscape-level movement. Our research emphasises advantage strategically investment support biodiversity.

Time Is Not Money: Income Is More Important Than Lifestage for Explaining Patterns of Residential Yard Plant Community Structure and Diversity in Baltimore

Frontiers in Ecology and Evolution, Год журнала: 2020, Номер 8

Plant biodiversity is affected by limiting resources such as water, nutrients, and sunlight. In urban settings, residential yards, however, may also include the social factors of time money spent on yard care. To examine role that these precious human play in determining plant community structure diversity, we surveyed homeowners their yards 12 neighborhoods across Baltimore City County, Maryland, visiting a total 96 properties. We chose based residents’ median income (a proxy for money) lifestage time) determined ESRI’s Tapestry dataset (older [>65 most likely retired with more free time] versus younger [<65 working less time]). At each yard, studied four major types: lawn species, flowering herbaceous plants (excluding grasses), trees, invasive species. For plants, documented number, size, color flowers, calculated floral area. found harbored high diversity 89 tree 82 80 genera. Lawn richness was not related to neighborhood-level residents or income, rather, all lawns were equally weedy. Consistently, higher larger had greater abundance trees whereas rarely associated diversity. Additionally, front area than back while yards. Finally, who doing work flower colors, Overall, high-income neighborhood, large greatest biodiversity, indicating resource creating maintaining biodiverse

Urban Green Space Composition and Configuration in Functional Land Use Areas in Addis Ababa, Ethiopia, and Their Relationship with Urban Form

Land, Год журнала: 2021, Номер 10(1), С. 85 - 85

This study aimed to assess the compositions and configurations of urban green spaces (UGS) in functional land use areas Addis Ababa, Ethiopia. The UGS data were extracted from Landsat 8 (OLI/TIRS) imagery examined along with ancillary data. results showed that high-density mixed residence, medium-density low-density residence contained 16.7%, 8.7%, 42.6% UGS, respectively, together occupied 67.5% total area. Manufacturing storage, social services, transport, administration, municipal function, commercial 11.6%, 8.2%, 6.6%, 3.3%, 1.3%, 1% account for only 32% indicating two-third found residential areas. Further, 86.2% individual measured less than 3000 m2, while 13.8% greater demonstrating a high level fragmentation. also there strong correlations among landscape metrics, relationship between form metrics was moderate. Finally, more studies need be conducted on spatial pattern characteristics using very high-resolution (VHR) images. Additionally, future planning, design, management guided by an understanding composition configuration UGS.
