With mandatory closures and quarantines that compel people to stay at home, wild animals and plants benefit from the calm they have been missing for a long time.

In the early days of domestic isolation, residents of big cities began again to hear birds singing, as wild boars were seen laying on the streets of Barcelona, ​​a small American puma roaming in Santiago and dolphins gathered in the Mediterranean.

With the decline of the human presence, wild animals in urban areas were "free to move around the cities," Roman Juliard, director of research at the National Museum of Natural History in Paris, told AFP.
He cites the example of foxes "that she changes her behavior very quickly. When there is quiet space comes to it. " Thus, animals and birds that live in urban areas, such as birds, pigeons and crows, can leave their usual lands "and make room for other animals."

Did the numbers of birds increase? Jeron Soyor, an acoustics specialist at the National Museum of Natural History, explains that we have heard it better, adding: “Some of them stop tweeting when they hear a commotion. But now I stopped it. ”

"The noise disturbs her behavior and generates stress." We hope that the disappearance of human voices will be "beneficial" for the animals during the breeding period in the spring. The researcher adds "the animals were rid of human noise and noise."

Wildlife can be better both in the countryside and in the sea. In France, for example, house insulation ended the fishing season early.

Quarantine may be appropriate in times of reproduction, especially for some animals such as frogs and spotted salamanders "that cross roads and are regularly run over," according to Jean-Nouvel Reville, regional director of the French Bureau for Biodiversity in Val de Loire.

Gulls that nest on the sand dunes are usually disturbed in Loire, but currently there is nothing to disturb, no pedestrians, dogs or even boats.
"Nature, animal and plant species find their natural spaces with surprising speed," said Didier Ryo, director of the National Park in Clank (near Marseille). After the marine puffins were nesting on the archipelago in areas far from humans where they obtained a high degree of protection, they now returned to collect in the waters.

The same applies to plants. Jean-Noel Reville says the wild orchids that grow between the end of April and the beginning of May, sometimes picked up by pedestrians, may survive that fate this year.

In the city, meadows will bloom and provide resources for bees and butterflies, as Juliard explains.
For scientists, "this may be the most important phenomenon for how we change our perception of nature: isolated people understand how they lack nature."
During their homework, they find time to watch and explore nature from the window or in the garden.

However, isolating humans can be bad news for food-habitual species from their waste, or because aid operations of endangered species or invasive species have stopped, according to Luik Opelde, deputy director-general of the office.

It will be necessary to manage the process out of isolation. "There will be a need for nature, and you will see a congestion that is not conducive to plants and animals," warns Jean-Noel Revell. For example, birds that build their nests will be disturbed in a school playground. This means that the respite from humans to animals and plants will only be short-lived.
