This problem has been solved! The bird was classified as vulnerable.During the 1970s and 1980s, governments and conservation groups worked to help the brown pelican recover. One way to try to protect species is to focus on areas with high species diversity. When there are very few animals left within a range where they can safely mate with other animals and raise offspring, and there is no habitat containing a large number of those same animals, their species is in danger of extinction. One way to try to protect species is to focus on areas with high species diversity. Generally speaking, they are animals and plants that are in decline and may be in danger of extinction. Collars AAA and BBB start from rest, and collar AAA moves upward with an acceleration of 3t2mm/s23 t^2 \mathrm{~mm} / \mathrm{s}^23t2mm/s2. Some species do really well after a disturbance. Overfishing, poaching, and dam construction have caused this decline. Many courts have harshly criticized this approach. Second, many pigeons were shot for sport and because they were good to eat. invasive species, also called introduced species, alien species, or exotic species, any nonnative species that significantly modifies or disrupts the ecosystems it colonizes. HIPPO stands for Habitat destruction, Invasive species, Pollution, Population(human), and Overharvesting- the leading causes of extinction. Endangered Species Examples With fewer breeding pairs, genetic variation shrinks.Monoculture, the agricultural method of growing a single crop, can also reduce genetic variation.
