原文：The concept of conservation-reliant species refers to that if a human focuses on recreating and maintaining original habits for some of the species, they will become dependent on human conservation, and without human's assistance, these species may become extinct. The concept of conservation-reliant species implies that when humans focus on recreating and maintaining the original habitats for certain species, these species become dependent on human conservation efforts, and without such assistance, they may face extinction.（将“refers to that if a human”改为“implies that when humans”，使句子更自然；将“habits”改为“habitats”，修正单词错误；将“human's assistance”改为“such assistance”，使句子更通顺。）

And a professor in the lecture mentions that in some of the forests where bird species lived there originally, when some other species like sheep or cows are brought there, they destroy their habitats. The professor in the lecture mentions that in certain forests where bird species originally lived, the introduction of other species like sheep or cows leads to the destruction of their habitats.（将“in some of the forests where bird species lived there originally”改为“in certain forests where bird species originally lived”，使句子更自然；将“when some other species like sheep or cows are brought there”改为“the introduction of other species like sheep or cows”，使句子更通顺。）

So human beings make fences to keep out these species to recover birds' habitats. As a result, humans construct fences to exclude these invasive species and help restore the birds' habitats.（将“make fences”改为“construct fences”，使用更高级的词汇；将“to keep out these species to recover birds' habitats”改为“to exclude these invasive species and help restore the birds' habitats”，使句子更自然。）

However, although the measure is really expensive but also effective, when the measure is seized, the birds may become hard to survive. However, while this measure is costly yet effective, if it were to be discontinued, the birds might struggle to survive.（将“although the measure is really expensive but also effective”改为“while this measure is costly yet effective”，使句子更自然；将“when the measure is seized”改为“if it were to be discontinued”，修正语法错误；将“the birds may become hard to survive”改为“the birds might struggle to survive”，使句子更通顺。）

The concept of conservation-reliant species implies that when humans focus on recreating and maintaining the original habitats for certain species, these species become dependent on human conservation efforts, and without such assistance, they may face extinction. The professor in the lecture mentions that in certain forests where bird species originally lived, the introduction of other species like sheep or cows leads to the destruction of their habitats. As a result, humans construct fences to exclude these invasive species and help restore the birds' habitats. However, while this measure is costly yet effective, if it were to be discontinued, the birds might struggle to survive.
