| 14 | 02:50 | Yet in the middle of this ice world there is scalding heat. | 然而在这一个冰冻世界的中央却有滚烫的热量 | |
| 15 | 03:00 | This is no ordinary place and this is no ordinary winter. | 这是一个不寻常的地方这儿的冬天同样不寻常 | |

| 20 | 03:44 | And its location is what makes it so different. | 正是它所处的位置让它如此与众不同 | |
| 21 | 03:54 | Right beneath Yellowstone a unique quirk of geology means that molten rock from deep in the earth comes unusually close to the frozen surface. | 在黄石公园的下方隐藏着一种奇特的东西地质学上称之为岩浆（火山溶岩） 从地球的深处几乎直通到冰冻的地表 | |
| 23 | 04:07 | No one knows why it happens right here but its impact is what has made Yellowstone world famous. | 没有人知道为什么刚好通到这里 然而正是岩浆的喷发作用使黄石公园闻名于世 | |

| 49 | 08:15 | It's stalemate. | 现在陷入僵持状态 | |
| 50 | 08:22 | But it's now the elk that has a problem of his own. | 但是又轮到麋鹿的问题了 | |
| 51 | 08:29 | Although it's only knee deep he can't stay in this freezing water forever. | 它的脚再长也不可能永远地呆在冰水里 | |

| 91 | 12:46 | The last eruption 640000 years ago was more than 1000 times larger than Mount St Helens. | 最后一次的爆发是在640000年前 其规模超过圣海伦火山爆发的1000倍 | |
| 93 | 12:57 | It blasted away mountains and ejected hundreds of cubic miles of debris into the atmosphere burying half the USA with ash. | 山体迸裂成百立方英里的碎片四散空中 将半个美国埋在火山灰里 | |
| 95 | 13:12 | The heart of Yellowstone is one of the world's biggest volcanoes. | 黄石公园的心脏是世界上最大的火山 | |
| 96 | 13:19 | One day it will erupt again. | 总有一天它还会再次爆发 | |
| 97 | 13:23 | It could be today or in another million years. | 可能就是今天也可能百万年后 | |
| 98 | 13:30 | But even as the volcano is sleeping breathing quietly through its geysers it has a profound effect on Yellowstone's winter. | 但是就算火山处于休眠 只是通过喷泉安静地呼吸 也会对黄石公园的冬天有极深影响 | |
| 101 | 13:49 | The volcano made Yellowstone's giant bowl but it didn't stop there. | 火山制造了巨碗状的黄石公园但它并未就此停歇 | |
| 102 | 13:54 | Ever since the huge pressure below the surface has been pushing it higher into the air and as it gets higher it gets colder. | 自那时起地表下巨大的压力 将黄石公园越抬越高 地势越高也就越寒冷 | |
| 105 | 14:05 | And now at its present altitude of 8000 feet this giant bowl simply accumulates freezing air from the surrounding mountains. | 它现在高度是8000 英尺 这个庞大的碗汇集了来自周围山脉的 冰冻的空气 | |
| 108 | 14:18 | In the winter the sleeping volcano becomes a giant deep freeze. | 在冬天沉睡的火山极度深寒 | |
| 109 | 14:33 | On the open plateau right in the middle of this frozen volcano is an animal that has lived here since the last ice age. | 在这座冷冻火山中央的开阔高地 有一种动物自从上一个冰河时代就居住在此 | |
| 111 | 14:45 | Bison are exposed to the worst of the Yellowstone winter but they are built for it. | 野牛忍受着黄石公园的严冬 但是它们生就了应对严冬的本领 | |
| 113 | 14:53 | Their thick coat is such good insulation that they only need a tiny amount of energy to keep warm. | 它们厚厚的皮毛阻隔了严寒 因此它们只要耗很少的能量来保持温暖 | |
| 115 | 15:01 | So they slow their metabolism right down and concentrate on feeding. | 它们减慢他们的新陈代谢专注地吃草 | |
| 116 | 15:13 | With massive neck muscles they sweep their heads down through the snow to get to the grass beneath. | 靠脖子上强大的肌肉它们的头可以拱进积雪里 找到埋在雪中的草 | |
| 118 | 15:23 | But the grass has long ago put its summer goodness down into its roots and now has about the same nutritional value as cardboard. | 但是草早已将夏天积蓄的能量贮藏到草根 现在有象厚纸板一样的营养价值 | |
| 120 | 15:34 | They will need to do all they can to save energy if they are to ward off starvation until spring returns. | 他们会尽一切可能来保存能量 只要他们在春天到来前不挨饿 | |
| 122 | 15:50 | As the winter strengthens its grip elk move into more sheltered valleys at the edge of Yellowstone. | 当严冬来临 麋鹿迁入黄石公园边缘能提供更多庇护的山谷内 | |
| 124 | 15:59 | They don't have the bison's ability to move deep snow. | 因为他们没有能力象野牛那样弄开厚厚的积雪 | |
| 125 | 16:08 | But this brings them into the territory of the Druid pack. | 他们被迫进入德鲁伊狼群的领地 | |

| 131 | 16:53 | But their play has a purpose. | 但他们的游戏有一个目的 | |
| 132 | 16:56 | It fine-tunes their hunting skills and helps bond the all-important pack structure. | 提高狩猎技能 也有助于加强非常重要的族群关系 | |

| 142 | 19:22 | It's December and even the great Yellowstone River is succumbing to the cold. | 现在是十二月就连黄石公园河 也不得不屈服于寒冷 | |
| 144 | 19:30 | It's only where the water runs fast that it still runs free. | 只有流速够快的水还能自由地流淌 | |
| 145 | 19:41 | It looks uncomfortably cold but then the water at around freezing point can be 50 degrees warmer than the air. | 在令人不舒服的寒冷中 冰点附近的水 居然比周围的空气还热 50 度 | |
| 148 | 19:53 | Under the ice there's a rich supply of stone fly larvae waiting to hatch in the spring. | 在冰层下面有大量的石蝇幼虫 等候在春天孵化 | |

| 153 | 20:27 | Yellowstone Lake is 136 square miles and now completely covered in three feet of ice. | 黄石公园湖面积有136平方英里 现在整个被覆盖在三英尺厚的冰层下 | |
| 155 | 20:42 | A coyote travels across this frozen desert looking for something to eat. | 一只土狼横穿这一冰冻的沙漠找寻吃的东西 | |
| 156 | 20:49 | It's a wonder that anything can survive here at all. | 这里的一切都能存活确是一个奇迹 | |
| 157 | 20:54 | Hundreds of feet beneath him on the lake bed geysers erupt just like they do on land and they melt holes in the ice the only sign that there is a lake here at all. | 在他脚下数百英尺的湖床上 喷泉仍象在地面上一样喷发 它们在冰面上融开的洞 是告诉人们这有一个湖泊的唯一的告示 | |
| 161 | 21:15 | As the year comes to an end it seems hard to imagine this winter getting any tougher. | 当一年即将结束的时候 很难想像的这冬天还会变得更严酷 | |
| 163 | 21:23 | But there's another twist to the volcano's story that is about to make things even worse. | 但火山的故事还有另一个波折 将要使事情变得更糟糕 | |
| 165 | 21:35 | Over time the continent of North America has moved inch by inch over many millions of years. | 北美洲的大陆 在过去数百万年内一寸一寸的移动 | |
| 167 | 21:44 | But deep down below the Earth's moving crust the source of magma that fuels Yellowstone's volcano has stayed put. | 在移动的地壳下方深处 黄石公园火山燃料的来源--岩浆 停留在原地没动 | |
| 170 | 22:03 | As the crust has moved over this volcanic hotspot eruption after eruption has blasted a massive 500-mile-long scar right through the Rockies. | 当地壳移出这个火山的喷发点时 一次次的爆发产生了一道巨大的500英里长的疤痕 贯穿整个落矶山脉 | |
| 173 | 22:21 | In the winter this giant scar called the Snake River Plain funnels moist air from the Pacific Ocean right through the wall of the Rocky Mountains and up into Yellowstone's deep freeze. | 在冬天来自太平洋的潮湿空气 经由这道被称为蛇河平原巨大疤痕 穿过洛矶山脉的屏障 进入到黄石公园 | |

| 190 | 25:27 | This year is already the snowiest for the last decade snowier than many of this herd have experienced in their lives. | 今年是十年来降雪最多一年 对于动物中的大多数来说在他们生命的经历中从没见过这么大的雪 | |
| 192 | 25:36 | Now as the snow gets deeper than a critical four feet the effort of swinging this massive head back and forth for so little reward is becoming too much. | 现在当雪深超过关键的四英尺 努力地来回摇晃巨大的脑袋才换来这一丁点的回报 实在太不值了 | |
| 195 | 25:53 | Though the snow front is passing through it's followed by the wind which now starts to scour the heart of Yellowstone. | 虽然降雪的前锋正在通过 紧跟着又是风 现在开始涤蕩黄石公园的心脏 | |
| 198 | 26:25 | A bison's coat can keep it warm down to minus 30 degrees Fahrenheit. | 野牛的皮毛能在零下30度使它保持温暖 | |
| 199 | 26:33 | The wind chill is now pushing these bison to that limit. | 寒风现在将这些野牛逼到了极限 | |

| 202 | 26:54 | They know what to do. | 他们知道该怎么做 | |
| 203 | 27:12 | To move is risky it will tap into their now dwindling energy reserves. | 走动是冒险的会耗掉他们现在日益减少的能量储备 | |

| 205 | 27:29 | Their way out is a river whose water is not frozen. | 他们的希望是一条河水还没被冻结 | |
| 206 | 27:36 | A thermal river fed by warm water from Yellowstone's geysers an ancient route which leads to a place where if they're lucky they will be able to survive. | 一条有黄石公园的地热喷泉暖水补充的温暖河流 一条远古的路径通往某处如果他们很幸运 他们将会在那里幸存下来 | |
| 209 | 28:07 | It's January and night is twice as long as day in Yellowstone's deep freeze. | 一月现在夜长是日长的两倍 深寒的黄石公园 | |
| 211 | 28:13 | The wind and the storms have gone but now the clear skies suck any last trace of heat into space. | 风和暴风雨已经过去 但是现在晴朗的天空把任何一丝热量吸入空中 | |
| 213 | 28:25 | As morning comes something extraordinary has happened. | 黎明到来的时候一些特别的事发生了 | |

| 219 | 30:12 | This bison is still out on the open plateau. | 一只野牛仍在开阔的高地上 | |
| 220 | 30:16 | The deep snow with its windblown crust has made it almost impossible to feed. | 风吹过雪面草几乎不可能吃到 | |
| 221 | 30:21 | The extreme cold will now tip the balance of survival further most likely too far even for a bison. | 这种极端的寒冷对于生存下去的考验 即使对一头野牛来说也太过严酷 | |
| 223 | 30:49 | A red fox can stay in the cold heart of Yellowstone all winter so long as it can find food. | 一只红狐狸能整个冬天呆在黄石公园的心脏地带 只要它能找食物 | |
| 225 | 30:57 | It's looking for mice that survive the winter insulated beneath the blanket of snow. | 它正在找寻老鼠 好不容易在冬天的雪毯下存活下来的 | |
| 227 | 31:08 | The fox is light enough to move about on the delicate crust but the mice are six feet beneath it. | 狐狸身体很轻能在脆弱的雪壳上走动 但老鼠在它下面六英尺的地方 | |
| 229 | 31:40 | It listens for the tiny sounds of its prey moving about below but must take great care not to scare them away. | 它倾听猎物在下面移动的微弱声音 但是一定极其小心不要把他们吓走了 | |
| 231 | 32:42 | The otter family has arrived at Yellowstone Lake. | 水獭家庭抵达了黄石湖 | |
| 232 | 32:47 | Here they can fish in the holes kept open by the underwater geysers. | 水下喷泉使这些冰洞保持开放他们可以在这里抓鱼了 | |
| 233 | 32:58 | But every time they catch something this coyote has been watching and waiting. | 可每一次他们抓到猎物 这一只土狼都会在一旁一直看着等候着 | |
| 235 | 33:37 | The otter dives under the ice to hide its fish from the coyote. | 水獭在跳到冰面下把它的鱼藏起来 | |

| 241 | 34:45 | With the help of the otters a wily coyote can catch fish too. | 有了水獭们“帮忙”一只狡猾的土狼也能“抓”到鱼 | |
| 242 | 35:16 | The thermal river has led the bison to one of the main geyser fields. | 热河引导野牛来到了其中一个主要地热喷泉 | |
| 243 | 35:25 | Here the heat from below comes close enough to the surface to melt the snow. | 这里地热传到很靠近地面足以融化积雪 | |
| 244 | 35:33 | And a bison can graze as if it were spring. | 野牛可以吃草看上去就好象是春天 | |
| 245 | 35:47 | The same volcanic forces so massive that they created the weather that drove the bison here now offer comfort. | 同样的火山巨大力量造成了恶劣天气 驱使野牛跋涉至此现在却又让它们如此舒适 | |
| 247 | 36:03 | The only problem is the grass that the bison now relish has such a high concentration of silica that it wears down their teeth. | 唯一的问题是 野牛现在吃的草富含二氧化硅会磨掉它们的牙齿 | |
| 249 | 36:12 | And it's laced with enough arsenic to slowly poison them. | 而且配上大量的砷慢慢地毒害他们 | |
| 250 | 36:24 | For these bison it's not an easy choice to come here. | 对这些野牛来说来这里是个两难的选择 | |
| 251 | 36:31 | But as long as they don't have to stay here too long it's a lot better than facing the Yellowstone winter head on. | 但只要它们不要在这里停留过久 总比直接面对黄石公园的冬天要好得多 | |
| 253 | 36:47 | Incredibly there is life that thrives here. | 令人难以置信的是这里有繁荣的生命 | |
| 254 | 36:51 | In Yellowstone's thermal springs the temperature is a constant near-boiling. | 在黄石公园的热泉 温度是接近沸腾的恒温 | |
| 256 | 37:00 | Yet here are huge colonies of heat-tolerant microbes. | 然而这里是耐热细菌的巨大殖民地 | |

| 116 | 13:15 | It goes back for more and more. | 接着又飞回去 一次 又一次 | |
| 119 | 13:29 | Over the autumn a single bird can bury 30000 nuts across an area of 1 00 square miles. | 在秋季一只鸟能在100平方英里的面积里 埋下30000颗松仁 | |
| 121 | 13:38 | When the winter comes it will manage to remember the location of a staggering 70% of these seeds even when hidden beneath the snow. | 当冬天来的时候 它会设法记得这些种子的位置记得住的达到惊人的70% 就算被雪隐埋了起来 | |
| 124 | 13:55 | But as the Clark's Nutcracker remembers its way into surviving the winter it becomes the whitebark's greatest ally. | 而当星鸦记住它在冬天求生之道的同时 它也成为了白皮巴尔干松最伟大的盟友 | |
| 126 | 14:04 | Although its feat of memory is extraordinary for every 1000 seeds it buries it still forgets 300. | 虽然它记忆的本领非凡 但它埋下的每1000颗种子中它仍然会忘掉300颗. | |
| 128 | 14:16 | From all those missed seeds carried far and wide across Yellowstone new whitebark pines will germinate next spring. | 这些被远携到黄石各地并被遗忘的种子 使得新的白巴尔干松在来年春天生根发芽 | |
| 130 | 14:48 | It's now September and the elk have made their way down to graze where the grass on the river banks is still green and they can browse the nutritious shoots of young willow trees. | 九月 麋鹿已经下到还有青翠草地的 河岸边来吃草 而且他们可以品尝新生柳树的营养嫩芽 | |
| 134 | 15:18 | The males are now upping their game. | 雄性们的游戏正在火热进行中 | |
| 135 | 15:25 | This bull urinates on himself to increase his masculine appeal and by thrashing his antlers to decorate them he hopes to make himself look more impressive. | 这头公牛往自己身上小便以突显他的雄性诉愿 并猛摇他的鹿角来给他们涂上泥 他希望把自己弄得看起来更令人印象深刻 | |

| 144 | 16:08 | They are now focused on feeding as much as they can before moving lower still. | 在安静地往低处转移之前 她们目前专注于尽可能多地觅食 | |
| 146 | 16:19 | But the elk are being watched. | 但这头麋鹿被盯上了 | |
| 147 | 16:21 | (WOLF hOWLING) | （狼嚎） | |
| 148 | 16:30 | Over the summer wolves have been less mobile because of their young pups but their strength is building again. | 夏天里他们因为幼崽而不太走动 但他们正在重拾力量 | |
| 150 | 16:52 | The elk get twitchy and head for the cover of trees. | 麋鹿惊慌起来跑到树林里找掩护 | |
| 151 | 17:03 | They may be a little safer here but the food in the forest is far less nutritious than on the river banks. | 在这里他们相对比较安全些 可是森林里的食物营养成份远不如在河岸上的 | |
| 153 | 17:20 | If they want to eat well and avoid wolves this winter they'll need to keep on moving. | 如果他们又想吃得好又想在冬天避免狼群 他们就得继续迁徙 | |
| 155 | 17:25 | (BARKING) | （狼嚎） | |
| 156 | 17:35 | As the elk move gradually downwards they follow the rivers out of Yellowstone's central plateau. | 当麋鹿逐渐地向低处迁移 他们一路顺着从黄石公园中央高地流出的河流 | |
| 158 | 17:48 | The rivers in turn follow the path of glaciers that flowed from this great bowl in the last ice age and carved their way right through the barrier of surrounding mountains. | 而河流则循着在上一个冰河时代 从周围山峦的包围中冲开一条路 并流出这个巨碗的冰河的径迹 | |
| 161 | 18:07 | Today these valleys are escape routes for animals from the returning ice of winter. | 今天这些山谷成为 动物们从重返这里的冬天冰雪之中逃脱之路 | |
| 163 | 18:24 | Lower down the valleys broaden the rivers slow and a richer variety of trees grows in the alluvial soils the perfect home for Yellowstone's most industrious creature. | 往低处去山谷变宽河流变缓 在冲积的土壤里长出品种丰富的树林 成为黄石公园里最为勤勉的生物完美的家园 | |
| 166 | 18:40 | (SPLINTERING AND CRACKING) | （开裂声） | |
| 167 | 18:58 | A beaver can fell a cottonwood tree in just a few hours hundreds in a year. | 一只海狸只需数小时就能放倒一棵三角叶杨 一年能弄倒数百棵 | |
| 169 | 19:09 | The beaver doesn't chew through the whole trunk just enough to make the tree unstable. | 海狸不会啃断整个的树干 只要做到让树变得不稳 | |
| 171 | 19:14 | It then retreats and lets the wind do the rest. | 它就可以后撤 让风来完成剩余的事情 | |

| 174 | 19:22 | (WIND BLOWING) | （风吹） | |
| 175 | 19:46 | It cuts branches into more manageable lengths and then swims them down a network of purpose-built canals towards the dam. | 它把树枝切割到比较易掌控的长度之内 然后带着树枝朝着水坝里一个有目的建造的运河网络游去 | |
| 177 | 20:00 | The pond gives this beaver protection from predators and the canals allow it to forage far into the forest carrying many times its own weight with ease. | 池塘给这只海狸防备掠食者提供保护 而运河让它能深入森林里面搜寻粮草 轻易地多次携带相当于它自己的重量的东西 | |
| 180 | 20:17 | Autumn is the busiest time of year for beavers. | 秋天是海狸一年之中最忙碌的时间 | |
| 181 | 20:21 | It won't be so easy to make repairs when the pond is frozen over. | 当池塘整个被冻结的时候修理工作将不会这么容易 | |
| 182 | 20:36 | The sound of running water is their stimulus to shore up gaps with timber and plug leaks with mud. | 流水的声音刺激他们 用木材支撑缝隙并用泥巴堵漏 | |
| 184 | 20:51 | But the dam not only serves the beavers. | 但水坝不只是为海狸服务 | |
| 185 | 21:03 | Moose come here from the forests around to feed on weeds that thrive in the beaver's shallow pond. | 大角鹿从附近森林来到这里 以海狸的浅池中生长茂盛的杂草为食 | |
| 187 | 21:13 | The weed is rich in vital sodium that the forest can't easily provide. | 杂草富含重要的钠这是森林不容易提供的 | |
| 188 | 21:21 | But now that winter is approaching another essential role for the dam is revealed. | 但现在冬天的脚步逼近 水坝另一个重要作用体现了出来 | |
| 190 | 21:40 | These smaller branches are not for fixing the dam they're for eating. | 这些更小的树枝不是修复水坝用的 是拿来吃的 | |
| 192 | 21:56 | The beaver secures them to the mud in the lake bottom. | 海狸将它们贮藏在湖底的泥里 | |
| 193 | 22:05 | In just a few weeks this lake will be frozen and the beavers won't be able to cut and move trees. | 几个星期内这个湖就会被冻结 海狸将不再能够砍伐和搬运树木 | |
| 195 | 22:13 | But they will be able to swim right under the ice to feed from this underwater larder. | 但是他们能够在冰面之下游来游去 并从这个水下食品贮藏室找吃的 | |
| 197 | 22:27 | Moose also eat twigs and branches and often try to take advantage of the beaver's hard labour. | 大角鹿也吃大小树枝 还经常想要占辛苦劳作海狸的便宜 | |
| 199 | 22:41 | This young male is getting a little too close to the beaver's larder. | 这头年轻雄鹿离海狸的食品贮藏室有点太近了 | |

| 206 | 23:39 | They now digest the green pigments in their leaves to claw back what nutrients they can into the trunk and roots. | 他们现在消化树叶中的绿色色素 尽他们所能夺回营养输送入树干和树根之内 | |

| 210 | 24:45 | Each grove descended from one tree interconnected by roots colour-coordinated. | 每棵树牵动一整个树林 连气同根 色调统一 | |
| 213 | 25:06 | As cold air sinks further down from the mountains it brings autumn mist to Yellowstone's valleys. | 当冷空气从山里进一步下沉 它给黄石公园的山谷带来秋天的雾 | |
| 215 | 25:25 | It was in the autumn of 1 870 that the first official exploration party to Yellowstone began to plan for the creation of the world's first national park the beauty of Yellowstone's autumn inspiring a complete change in the way we value the wild. | 1870年秋天的时候 为创建世界上首个国家公园 组织了对黄石公园的首次官方探险活动 黄石公园秋天的美丽 导致人们对原野的评价方式发生完全的转变 | |
| 220 | 25:53 | (BUGLING) | （鹿鸣） | |
| 221 | 26:15 | For the last six weeks of strutting and herding male elk have eaten almost nothing. | 在过去六个星期的群居并充当顶梁柱 公麋鹿几乎是不吃不喝 | |

| 227 | 26:47 | But they are being distracted by another male. | 但来了另外一头雄性使她们分心 | |
| 228 | 26:49 | (SHRILL BUGLING) | （尖锐的鹿鸣） | |
| 229 | 26:58 | If a bull elk can't dominate all rivals he can't have access to the females and all his effort will have been in vain. | 如果一头公红牛麋鹿战胜不了所有的对手他就没有机会获得母牛 那他之前所有的努力将会枉费 | |

| 244 | 28:54 | After all this effort he will now have to wait until next autumn to try his luck again. | 在所有这些努力之后 他现在只好等着来年秋天再试试他的运气 | |
| 246 | 29:02 | That's if he even makes it. | 哪还得要他做得到才有可能 | |
| 247 | 29:08 | Bull elk exhausted by the rut struggle to survive the Yellowstone winter. | 因发情而筋疲力尽的红牛麋鹿 还得努力在黄石公园冬天里求生 | |
| 249 | 29:25 | It's now October and the winter is catching up with the elk once more. | 现在是十月 冬天正在再一次追赶麋鹿的脚步 | |
| 251 | 29:36 | An early flurry of snow is a sign that it's time to make a decision. | 早冬的大雪宣告到该作决定的时候了 | |
| 252 | 29:40 | To stay is to face the certainty of snow and wolves. | 留下来不可避免的要面对大雪和狼群 | |

| 256 | 30:11 | Every autumn thousands of elk do leave Yellowstone. | 每个秋天数以千计的麋鹿会离开黄石公园 | |
| 257 | 30:15 | And as they go they cross an invisible line out of the protection of the National Park. | 而且当他们离去他们将越过一条 隐形的界线而失去国家公园的保护 | |
| 259 | 30:22 | Here they confront new danger. | 在这里他们面临新的危险 | |

| 263 | 31:10 | (GUNShOT) | （枪声） | |

| 265 | 31:20 | Elk of course have no understanding of park boundaries or of Yellowstone. | 对麋鹿来说当然不可能理解什么是公园界限或黄石界限 | |
| 266 | 31:25 | To them this is simply an instinctive migration to find more hospitable land so they just keep going. | 对他们这只是本能的迁徙 为了寻找更宜人的土地而不停前进 | |
| 268 | 31:39 | Beyond the ring of hunting lands the natural mosaic of forest and grass is replaced by an alien geometry. | 越过环状狩猎带 森林和草地的天然马赛克 被截然不同几何形状代替 | |

| 275 | 32:10 | It's unlikely they'll be welcome here. | 在这里他们不太可能受到欢迎 | |
| 276 | 32:22 | By now the pronghorn have pushed further than any of the Yellowstone's animals. | 到如今叉角鹿已经比黄石公园的任何动物 都推进得更远 | |
| 278 | 32:27 | Out of forests through farmland and down into the wide prairies at the foot of the Rocky Mountains themselves. | 从森林中走出穿过农场 下到他们的落矶山脉 脚下的广袤的草原 | |
| 281 | 32:43 | Their search for winter grazing takes them over 1 00 miles to the south of Yellowstone the longest migration of any American mammal. | 他们为了在冬天找寻食物 走到了黄石公园以南超过100英里的地方 是美国所有哺乳动物中最遥远的迁徙 | |
| 284 | 33:00 | They have made this journey every year since the last ice age. | 从上一次冰河时代起他们每年都重复这趟旅程 | |
| 285 | 33:04 | But nowadays they have a problem. | 但时下他们有一个问题 | |
| 286 | 33:11 | (TRUCK hONKING) | （卡车鸣笛） | |
| 287 | 33:14 | Their traditional winter refuges lie right above some of the richest natural gas deposits in America. | 他们传统的冬天避难所 恰好位于美国最富藏天然气的地方 | |
| 289 | 33:29 | The wells are no direct threat to pronghorn. | 油气井对叉角鹿并非直接的威胁 | |
| 290 | 33:36 | But pronghorn are timid. | 但是糜鹿很胆小 | |
| 291 | 33:39 | (TRUCK hONKING) | （卡车鸣笛） | |
| 292 | 33:41 | At the slightest noise they run and when they run they run at 60 miles per hour. | 听到最微小的噪音他们就会狂奔 而且当一跑起来他们的速度是每小时60英里 | |
| 294 | 33:52 | They evolved to avoid cheetahs not juggernauts. | 他们进化来躲避的是猎豹不是世界的主宰 | |
| 295 | 33:58 | Trucks fences and the disturbance from the wells have put pronghorn at risk. | 卡车围墙 和来自油气井的干扰已经使糜鹿处于危险中 | |
| 297 | 34:08 | There are 1.2 million acres here but 75% of it has now been earmarked for gas and oil. | 这里面积一百二十万英亩 但有75%现在已经预留给天然气和石油 | |
| 299 | 34:26 | Back in the farmland the elk have found food. | 回到农场里麋鹿找到了食物 | |
| 300 | 34:32 | But this grass is not meant for them. | 但是这些草不是给他们的 | |
| 301 | 34:37 | (COWS LOWING) | （牛叫） | |
| 302 | 34:47 | Ranchers will tolerate elk as long as they don't compete too much with their cattle. | 农场经营者可以容留麋鹿 只要他们不要与他们圈养的牛过分争食 | |
| 304 | 35:02 | But as the elk move in their old enemy follows them out of Yellowstone an animal that's more difficult for ranchers to accept. | 但是当麋鹿迁徙至此他们的老对头会从黄石公园跟踪到这里 这是一种农场经营者更难接受的动物 | |
| 306 | 35:16 | In their minds fear of the wolf runs deep. | 对狼的恐惧深植他们的脑海里 | |
| 307 | 35:24 | Even Yellowstone lost its wolves. | 尽管黄石公园的狼逐年减少 | |
| 308 | 35:28 | They were wiped out over 80 years ago. | 他们还是在80年前被消灭彻底 | |
| 309 | 35:35 | After years of prejudice they were reintroduced in 1 995 brought back by the authorities to restore Yellowstone's natural balance. | 在数年的偏见之后在1995年主管部门为了 修复黄石公园的自然平衡他们再度被引入 | |
| 311 | 35:49 | But the wolves have done so well that now they are moving out of the park looking for new territories and prey. | 但狼群发展势头如此之好 以致现在他们正从公园迁出找寻新的领地 和猎物 | |
| 314 | 36:03 | Out here it's clearer to see why wolves have a bad reputation. | 在这里更容易明白为何狼的名声那么坏 | |
| 315 | 36:21 | If ranchers' cattle are at risk by law wolves can be shot. | 法律上如果农场经营者的牛处于险境可以将狼射杀 | |
| 316 | 36:37 | As wolves come back ranchers are being forced to return to the old ways to get back into the saddle and protect their herds. | 当狼群回来时农场经营者被迫用回老办法 跨上马鞍保护他们的牛群 | |

| 321 | 37:04 | Working with scientists who have radio-collared the Yellowstone wolves ranchers can now keep track of them and when they know they are near shoot not to kill but to scare them away. | 与给黄石公园狼戴上无线电颈圈的科学家们合作 农场经营者现在能掌握他们的资讯 当他们知道狼群来近的时候 开枪把他们吓走而不是射杀他们 | |
| 325 | 37:21 | (CATTLE LOWING) | （牛叫） | |
| 326 | 37:36 | The return of the wolf will always be controversial. | 狼的返回问题会一直争论下去 | |
| 327 | 37:40 | But evidence is now emerging that wolves are far more important than anyone imagined especially back in the heart of Yellowstone. | 但现在证据显示 狼比任何人想像的都要重要 尤其是回到黄石公园的心脏地带 | |
| 330 | 37:58 | It's nearly the end of October. | 现在快十月底了 | |
| 331 | 38:04 | The cold autumn nights have brought a thin crust of ice to a beaver's pond. | 寒冷秋夜给一张海狸池塘带来薄薄一层冰 | |
| 332 | 38:07 | Unlike in the river valleys below up here there are not many tall cottonwood trees. | 不像在下面的河谷 在这样的高处没有那么多的高三角叶杨 | |
| 334 | 38:14 | So this beaver has built his dam from the shoots of young willows sprouting all along the side of his pond. | 因此这只海狸采用在他池塘边抽条发芽的 新生柳树的嫩枝来建造他的水坝 | |
| 336 | 38:35 | But he is something of a novelty. | 但其实他的存在多少有点新奇 | |
| 337 | 38:40 | Even by the time Yellowstone was made a national park beavers had been virtually hunted to extinction by fur trappers. | 即使当黄石已经被设立为国家公园 海狸还是几乎被毛皮猎人捕猎殆尽 | |
| 339 | 38:56 | They only began to reappear here in 1 995 the year the wolves came back. | 他们直到1995年才在这里重现 也是狼群回来的那一年 | |
| 341 | 39:10 | Now wolves are chasing elk again elk have had less time to eat willows so willows are sprouting everywhere. | 现在麋鹿被狼群所追逐使得麋鹿没什么时间吃柳树了 所以柳树到处发芽 | |
| 343 | 39:18 | Today as winter approaches all over Yellowstone beavers are using those willows to put the finishing touches to a dam-building renaissance. | 今天当冬天临近 整个黄石公园的海狸都在使用那些柳树 来为水坝建设的文艺复兴画龙点睛 | |
| 346 | 39:43 | And for every dam there is a new habitat for new life and a richer more diverse Yellowstone. | 而每一个水坝造就出一个为新生命提供的全新栖息地 和一个更富饶更多样化的黄石公园 | |
| 348 | 39:58 | (hONKING) | （雁鸣） | |
| 349 | 40:09 | But just as Yellowstone reveals the complexity of life it also exposes its fragility. | 但当黄石公园揭示生命的复杂性时 同时也暴露出它脆弱的一面 | |
| 351 | 40:19 | On its lofty ridges there are signs that all is not well with the whitebark pine. | 在它高高的山脊上 所有迹象表明白巴尔干松树情况不妙 | |
| 353 | 40:32 | From above it looks like autumn colours have come to an evergreen world. | 从上方看起来似乎秋色沾染了一个常绿的世界 | |
| 354 | 40:41 | But these trees are dying. | 其实这些树正在死去 | |
| 355 | 40:54 | Small eruptions of resin dot the trunk of the tree evidence of an invasion. | 树干上树脂的小疹状斑块 是被入侵的证据 | |
| 357 | 41:10 | Tiny beetles are chewing through the tree's outer defences. | 极小的甲虫正在啃穿这棵树的防御表层 | |
| 358 | 41:23 | Once inside they lay eggs that turn into larvae that eat the tree. | 一旦进入内部他们就产下会长成吃树的幼虫的卵 | |
| 359 | 41:34 | Each tree that is lost threatens all the animals that rely on its autumn bounty. | 每棵死掉的树 会给在秋天仰赖其恩惠的所有动物构成威胁 | |
| 361 | 41:47 | The only thing that can stop the beetles is extreme cold. | 唯一能阻止这些甲虫的是严寒 | |
| 362 | 41:54 | But recently the climate here has been getting warmer and warmer. | 但是最近这里的气候已经变得越来越暖 | |
| 363 | 42:00 | No national park can protect against that. | 没有哪个国家公园能够对抗气候变暖 | |
| 364 | 42:09 | This is a tree that needs a cold winter. | 这是种需要寒冬的树 | |
| 365 | 42:22 | It's now November and the elk have found their feeding grounds just in time the snows of winter at their heels. | 现在是十一月 麋鹿已经及时找到他们的牧场 冬天的大雪紧随而至 | |
| 368 | 42:39 | Here they join other herds who come to this place every year where the snow will be less deep and life a little easier. | 在这里他们加入到年年来此的兽群 这里的雪没那么深日子也好过一些 | |
| 370 | 42:55 | But today they graze on an island of grass surrounded by development. | 但是今天他们在一个被人类发展围住的 草的岛屿上觅食 | |
| 372 | 43:03 | As they run from the winter the fate of Yellowstone's animals outside the national park is decided not by the cold but by people. | 当他们从冬天出逃 黄石公园的动物在国家公园之外的命运 不是由寒冷而是由人类决定 | |
| 375 | 43:16 | (SQUAWKING) | （呱呱声） | |
| 376 | 43:19 | These elk are lucky. | 这些麋鹿是幸运的 | |
| 377 | 43:23 | This refuge has been kept aside to give them some degree of sanctuary. | 为了给他们提供一定的庇护所这个避难地被保留下来 | |
