Study: Elephants Disappearing from Parts of Africa
The number of elephants living in Africa continues to drop.
A survey reporting on elephant counts was released last week. It shows the future of the species is in trouble.
Elephants are facing extinction in parts of the Republic of Congo, Cameroon and Zambia, according to the Great Elephant Census (GEC).
The study estimated a population of 352,271 elephants in the 18 countries surveyed. That is a drop of nearly 150,000 elephants since 2007. The researchers say the population has been falling by about 8 percent each year.
The GEC points out one large reason for the decrease in the elephant population. Ivory poaching has led to the lower numbers of elephants in most of the countries surveyed.
Even more troubling is where the dead elephants are being killed. The study reported a high number of carcasses - around 12 for every 100 live elephants – are being found on protected grounds. This number was highest in Cameroon.
There, 83 carcasses were found for every 100 live elephants. Many of the elephants were victims of killing by poachers for their ivory.
Many of these protected areas for wildlife are located on Africa's savannahs. Savannahs are large flat areas of land with grass and very few trees.
The GEC was started in 2014. Its job is to monitor savannah elephants across Africa. All other studies and counts of elephants before this survey were estimates.
The survey was conducted by air. Researchers in dozens of airplanes counted the animals as they flew over the groups of elephants.
The census also used video cameras to help count the elephants.

上周，一份关于大象数量的调查报告出炉 。报告显示，未来大象种群的处境令人担忧 。
该报告对18个国家的352271头大象作出评估 。2007年之后，大象数量已减少了近15万头 。研究人员称大象数量每年以8%的速度减少 。
GEC报告对大象数量锐减的主因作出解释 。在受访的大多数国家中，象牙盗猎成为大象数量锐减的根本原因 。
更让人费解的是大象被猎杀的地点 。报告显示多数大象尸体（每100头大象中就有12头大象死亡）是在保护区被发现的 。该现象在喀麦隆最为严重 。
在喀麦隆，每100头活大象中约83头死亡 。多数大象皆因偷猎者想要偷盗象牙而被杀害 。
非洲的稀树草原上有很多野生动物保护区 。稀树草原是一片广袤的只有稀疏几棵树的草原 。
2014年，GEC才成立 。其职责就是侦查生活在非洲稀树草原上的大象 。该调查报告未发布之前，所有关于大象的研究和数量都是预估的 。
该调查是在空中进行的 。研究人员分别乘坐几十架飞机，在空中观察大象的数量 。
