Washington, D.C. is home to famous buildings, memorials and museums that visitors love. But it is also home to a large and beautiful green space. There are many arboretums in the city. Today, we take you to the United States National Arboretum, an active center for both scientific research and public education.

Many people who come to Washington are astonished when they first visit the National Arboretum. The Arboretum is only a short drive from the center of the city. However, visitors often feel like they are remote from the busy American capital. The Arboretum covers one hundred eighty hectares of green space in the northeast part of Washington. The area is famous for its beautiful flowers, tall trees and other plants. About nine thousand different kinds of plants grow there.

The National Arboretum was established by an act of Congress in 1927. Today, the United States Department of Agriculture’s Agricultural Research Service operates the Arboretum.

The goal of the Arboretum is to carry out studies and provide education in an effort to improve the environment. The goal includes protecting trees, flowers and other plants and showing them to the public. The National Arboretum is a popular stop for visitors to Washington. It is open every day of the year except December twenty-fifth, the Christmas holiday. Money is not necessary to visit the Arboretum.

As many as six hundred thousand people visit the Arboretum’s grounds each year. Hundreds of thousands of people also visit with the help of computers. They use the Arboretum’s Internet web site to learn about current research programmes and how to care for plants. Director Thomas Elias says Arboretum officials would like to see even more visitors. He says they believe that many people do not know it exists. Part of the problem might result from the fact that the Arboretum is about five kilometers from the closest train station. Many famous places in Washington are a short walk from Metrorail, the local train system.

The Arboretum is easy to reach by automobile or bus, however. About fifteen kilometers of roads have been built on the property. The roads connect to major collections and seasonal flowers. The Arboretum also welcomes people on bicycles. Disabled persons or those who want to walk only short distances may visit four beautiful areas that are close to each other.

Passenger pigeons(旅鸽) once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks(群) so large that they darkened the sky for hours.

It was calculated that when its population reached its highest point, there were more than 3 billion passenger pigeons--a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant bird in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.

Sadly, the abundance of passenger pigeons may have been their undoing. Where the birds were most abundant, people believed there was an ever-lasting supply and killed them by the thousands. Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.

By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by Americans’ need for wood, which scattered (驱散) the flocks and forced the birds to go farther north, where cold temperatures and spring storms contributed to their decline. Soon the great flocks were gone, never to be seen again.

In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons, but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birds survived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden on September 1, 1914.
