Some species, such as peregrine falcons, have survival rates or higher reproductive success in cities than in rural areas. Some even like the urban landscape. A 2017 analysis Of the 529 bird species worldwide, 66 urban were found only in urban areas, such as not only classical urban birds such as the feral pigeon, but also different species of owls, black onions, and black birds in different regions. According to another RevaluationDiverse communities of native bee species continue in different cities of the world and in several cases, local bees live in more diverse and densely populated cities than natural bees in local villages. Researchers in Australia recently Marked 39 “Incognito” species tolerate only small patches of urban habitat, including trees, shrubs, a tortoise, a snail, and even orchids.

Over the centuries, urbanization has resulted in the wholesale removal and fragmentation of natural plants. After the initial attack, a complex mosaic of fancy habitats consisting of native, non-native and invasive plants emerged, it was affected by buildings, roads and other weak surfaces and was contaminated with pollution.

Urban ecologists see these as a “filter” that makes it difficult for many species to maintain in the city, especially with specific habitat requirements. Myla Arnson, an urban environmentalist at Rutgers University, points out that, for example, so-called Ericaceous plants, such as blueberries and rhododendrons, which require acidic soils, are disappearing in cities. Probably a factor as to why they’re doing so poorly, he said.

While urbanization poses a significant threat to species and ecosystems, cities are increasingly “surprisingly diverse” with unconventional habitats that could provide important habitats or resources for indigenous biodiversity. ” Wrote Scientists at the University of Melbourne in a 2018 study Conservation Biology. These range from remnants of native ecosystems such as forests, wetlands and meadows to the green spaces of a traditional historic city such as parks, backyards and cemeteries as well as golf courses, urban farms and community parks. Also, as cities invest in green infrastructure to reduce environmental damage, wildlife is increasingly building wetlands with green roofs and setting up former brownfields and zero lots. And play a positive role in promoting the biodiversity of cities, writes the author of “can be appreciated through intentional design” Bioscience Article on “Biological desert delusion”.

In recent years, urban environmentalists have created a new niche in the field of conservation biology. A seminar paper published in 2014 analyzed 55 cities in different regions of the biological region with extensive inventories of resident plant life and lists of complete birds. According to Study, Cities retain most of their original biodiversity. The paper’s lead author, Aronson, and his colleagues also found that the plants and birds in the cities they studied had fallen far short of pre5 percent and the losing pre-urban density of 5 percent, respectively.

Another establishment Paper Published two years later, Australian scientists in urban conservation biology wrote that the cities, home to 300 per cent of the country’s paralyzed plants and animals in the southern part of the country, including Carnaby’s Black-Cockatoo, live only in south-western Australia. In fact, they found that cities have significantly more endangered species per square kilometer than non-urban areas. “Australian cities are important for the conservation of endangered species,” they wrote.

There are scientists Described In many ways, urban areas can benefit from regional biodiversity. For example, cities may be sheltered from pressures such as competition or predictions that confront native species in the surrounding landscape. The greater concentration of prey in the cities has been linked to the success of several urban rapists, including the Cooper hawk, the peregrine falcon, the crested goose, and the Mississippi kite. Cities also serve stopover sites where migratory birds can rest and refuel. Large city parks, such as Highbanks Park in Columbus, Ohio, provide critical stopover accommodation for thrash, warler and other migratory songbirds.
