The United States is suffering from an “epidemic of over-farming and pollinator declines,” and some species are doing worse than others, according to a report released Tuesday.
The report by the Center for Biological Diversity found that some species of flowering plants in the Western United States were on the decline, while others were on track to become more common.
It found that at least 20 species of plant in the eastern half of the United State are on track for declines, while another three species of plants in some regions are on the verge of being eliminated.
For the first time, the Center reported on a decline of more than 40% in the number of flowering trees in the country.
The trees are considered a critical component of many American ecosystems, including pollinators, which help pollinate crops and provide pollination services like fertilizing land.
The loss of flowering species in the U.S. is not unprecedented, according.
A similar trend is occurring in many other countries, and many are still struggling with the same issues.
But this is the first study to identify the causes of the decline in flowering plants, according the Center.
The report does not include any specific species of trees in question, but the report highlights some key issues that the report identifies.
The pollinators and pollinators-in-need syndrome are affecting flowering plants across the U, and they are not being dealt with in a way that is sustainable, the report said.
In some cases, species of crops are being used for purposes other than the purpose for which they were planted, such as ornamental plants.
The U.A.E. is a region of the country that includes parts of Texas, Louisiana, Mississippi, Arkansas, and Oklahoma.
This includes the state of Texas.
The United States, which has a population of about 14.5 billion, is one of the most pollinator-rich nations on Earth.
About 95% of all flowering plants are native to the United, according research published in 2016 by the Pew Research Center.
