The 16th meeting of the United Nations Conference on Biodiversity (COP16) in Rome has concluded with an agreement to adopt the first global plan for financing nature conservation, after three days of meetings. This meeting meant resuming the negotiations that began last October in Cali (Colombia), where the parties failed to reach an agreement on how to finance the Kunming-Montreal Global Biodiversity Framework reached at COP15, which aims to protect a third of the land and oceans by 2030.

One study suggests that conservation efforts are concentrated around a small number of charismatic species, such as elephants. However, there are undervalued species, such as fungi, plants and invertebrates, that are critical to the functioning of ecosystems. The research, published in the journal PNAS, analysed more than 14,000 conservation projects spanning a 25-year period - from 1992 to 2016. Of the nearly $2 billion allocated by the projects, 83% went to vertebrates. Plants and invertebrates each received 6.6% of the funding, while fungi and algae received less than 0.2%.

Two-thirds of biological conservation actions improve biodiversity or slow its decline, a meta-analysis claims. The study highlights the effectiveness of interventions focused on invasive species control, habitat loss reduction and restoration, and protected areas. The article, published in the journal Science, brings together the findings of 186 previous studies.   

One in five species included in the list of the Convention on the Conservation of Migratory Species of Wild Animals (CMS, to which Spain is a party) is in danger of extinction. These are data from the first global monitoring report on these species published by the World Conservation Monitoring Centre, a branch of the United Nations Environment Programme (UNEP). This figure rises to 97% for fish species. The authors warn that the situation has deteriorated in recent decades due to "intense levels of anthropogenic pressure". The presentation of the report coincides with the start of the COP on the conservation of these species in Uzbekistan (COP14).

Species of birds common in the marshes of Doñana as the common tern, the brown pochard, the marbled teal, the marsh harrier or the black-bellied sandpiper have recorded a decline in their population for more than a decade, a trend that accelerated since 2019. This is one of the conclusions of the Report on the conservation status of waterfowl in Doñana, published today by SEO/BirdLife.
