For my presentation today I want to tell you about how groups of elephants have been moved and settled in new reserves.
在我今天的演讲中，我想告诉大家大象群是如何迁移到新的保护区并定居的。
This is known as translocation and has been carried out in Malawi in Africa in recent years.
这被称为移地放归，这一行动已经在非洲的马拉维进行了多年。
The reason this is being done is because of overpopulation of elephants in some areas.
这样做的原因是某些地区的大象数量过多。
Overpopulation is a good problem to have and not one we tend to hear about very often.
种群过剩不是坏事，也不是我们经常听说的事。
In Malawi's Majete National Park the elephant population had been wiped out by poachers, who killed the elephants for their ivory.
在马拉维的玛杰特国家公园，大象种群已经被偷猎者消灭，他们为获取象牙而猎杀大象。
But in 2003, the park was restocked and effective law enforcement was introduced.
但在2003年，该公园重新放养大象并引入了有效的执法。
Since then, not a single elephant has been poached.
从那以后，再没有人偷猎大象。
In this safe environment, the elephant population boomed.
在这种安全的环境下，大象的数量激增。
Breeding went so well that there were more elephants than the park could support.
大象繁殖进行得如此顺利，以至于公园里的大象数量超过了它的可容纳量。
This led to a number of problems.
这导致了许多问题。
Firstly, there was more competition for food, which meant that some elephants were suffering from hunger.
首先，对食物的竞争更加激烈，这意味着一些大象正在挨饿。
As there was a limit to the amount of food in the national park, some elephants began looking further afield.
由于该国家公园的食物数量有限，一些大象开始去更远的地方觅食。
Elephants were routinely knocking down fences around the park, which then had to be repaired at a significant cost.
大象经常撞倒公园周围的栅栏，然后公园不得不花费巨资进行修复。
To solve this problem, the decision was made to move dozens of elephants from Majete National Park to Nkhotakota Wildlife Park, where there were no elephants.
为了解决这个问题，该国家公园决定将数十头大象从玛杰特国家公园转移到没有大象的恩科塔科塔野生动物园。
But, obviously, attempting to move significant numbers of elephants to a new home 300 kilometres away is quite a challenge.
但是，显然，将大量大象转移到300公里外的新家的尝试是一项相当大的挑战。
