Today is Darwin Day and we don’t have good news for migratory species

In a strange coincidence with the Darwin dayAn extensive one was published on Monday, February 12th Reports ofUnepdedicated to the United Nations Environment Program Status of migratory species This shows a situation in which there is little to celebrate. The report was presented on the occasion of Conference of the Parties to the UN Convention on the Conservation of Migratory Species of Wild Animals Starting today in Samarkand, Uzbekistan.

Data on the status of migratory species

The information contained therein Relationship indicate the state they are in species Subject of United Nations Convention for the Protection of Migratory Animals, about 1200 (mainly birds, followed by land and aquatic mammals, fish, reptiles and insects). Scroll through the list Species bewareIt turns out there is a lot of talk about it Flamingos, cranes, petrels, sea turtles, but also manta rays, sharks, jaguars, camels, bats, whales, sharks and crocodiles, to name just a few. According to the United Nations definition, a migratory species is defined as: An entire population or any geographically separate part of the population of a species or lower taxon of wildlife in which a significant proportion of its members occur cyclically and predictably crosses one or more jurisdictional boundaries National”.

The report provides a complete overview of the situation, but the key data that emerges is the 20% of the species studied are threatened with extinction, with different levels of threat. In the vast majority of cases, the situation has worsened compared to the past. Of all the migratory animals considered, fish are faring the worst, as almost all species considered are threatened with extinction. The reasons concern the destruction and fragmentation of habitatoverfishing, hunting, pollution (in all its forms, from plastic to pesticides to glowing ones), egg Climate change. All of these factors can cause animals to become off-track, disoriented, and impair their ability to obtain resources and reproduce. In this context, the report highlights an aspect that may not be so obvious. The migratory speciesBy definition, they are moving, which makes them more vulnerable to potential threats, i.e. during their migrations they may face different dangers in different areas. But some of these threats are worse than others.

The biggest threats

The document presented on Darwin Day particularly points the finger at the Habitat loss and overexploitation, more than against climate change, pollution, alien species and diseases. When it comes to habitat loss – or fragmentation – refers to various phenomena: such as the construction of a new road, the construction of dams, the deforestation, but also the construction of a new energy plant including wind turbines (major threat to birds).. “By restricting the movement of migratory animalsthe increase in anthropogenic influences on migration and rest corridors represents a significant threat to the phenomenon of migration itself,” and to adaptability of animals We read in the report that we can counteract climate change through relocation. In addition to the great danger of habitat destruction, there is Over-exploitation of animalsa term that refers to a range of anthropic practices that include: Hunting, fishing, Farm yard for food purposes and/or in the production of materials, but also for the adoption of “pets”

Can we change course?

If it’s true that things are for him migratory animals go badly, the document also suggests a number of concrete actions trying to “course correct.” That is why it is fundamental in the fight against habitat loss Identification of critical areas for migratory species and increased efforts to conserve them, but at the same time seek to mitigate the impact of any man-made infrastructure Migration routes both in the sky, at sea and on land.

To combat overexploitation, the UN recommends increasing it Monitoring illegal activities and overfishing and accidental fishing activities. A Revising fishing practices – particularly with regard to the use and abandonment of fishing vessel equipment – is also hoped for in the chapter dedicated to the recommendations against this pollution.
