0:04 >> (音乐) You walk down this little trail and then it kind of opens up into this space you would
0:08 never even realize exists when you're up sitting in a classroom on campus.
0:12[音乐]这对我来说是一种很好的感受方式
0:19 connected and know that everything I've been learning in all my classes
0:24有现实世界的含义，我可以看到仍然有好的事情要做.
0:29我们还有重要的工作要做
0:31就和自然世界建立了联系.
0:34[音乐]
0:45 >> The bio preserve was set up for the purposes of 研究 and education,
0:49，大约110英亩.
0:52它被分成两部分，
0:54西部保护区和东部保护区.
0:58这是一个减压的地方.
一点，这里很平静，更安静，
1:02 there's birds chirping, there's interesting beautiful things to look at.
1:07 There aren't really any other universities in Southeast Michigan that
1:10在主校区有一个自然保护区.
1:13这真的是一个关于多样性的岛屿.
1:15它真的被开发的海洋包围着，
1:18的城市化和郊区化.
1:19仅从生物多样性的角度来看，
1:22有这个资源真是太好了.
1:23[音乐]所以这整个地区是由一分，
1:32，这是一种特殊类型的湿地，这是它区别于其他类型的地方
1:35 of wetlands is that the water originates from groundwater.
1:39这是上涌的地下水，因为它在地下呆了很长时间，
1:43它有一种非常独特的化学成分，反映了当地的地质.
1:48这创造了非常专业化的植物群落
1:50 these fens and is one of the reasons that it's such a unique ecosystem.
1:57历史上，如果你观察这片湿地，
两点的时候景色非常开阔.
2:02 It was dominated by grasses and other herbaceous vegetation.
2:05但没有火，
2:07 what we have is woody encroachment from the perimeter that eventually
2:11 chokes out these wetland plants that would've been dominant historically.
2:14其中一个主要目标就是摆脱这些外来的，
2:17入侵的木本植物已经占据了主导地位.
彼前[背景]
2:35 >> We are gathered here today to witness
2:38 an iteration of a very ancient tradition among indigenous peoples.
2:45 The use of fire as medicine and as a way of caring for the land.
2:55 Prescribed burning has been the process of reintroducing fire
3点到火灾频发数千年的地方.
3:04结果，本地植物物种变得真正
3:09 well adapted and thrive on the impacts of prescribed fire.
3:13[噪音]野火肯定会造成破坏，但是
3:19我们在密歇根的火灾不像
3:23就是我们看到的西部的野火.
3:26这里的火离地面要低得多
3:30 and it's much more well contained and especially prescribed fire.
3:34它真的是一个必要的工具
3:38 most Michigan landscapes to really fully enhance the biological diversity.
3:43(噪声)
3:54[音乐]
4:04 >> So today we're going to take soil samples from each of our control and
4:08烧罐子，然后我们会把它们带回实验室
4:10，分析土壤含水量.
4:13 That's important because presumably the higher the water levels,
4:17 the more microbial activity and the higher the decomposition.
4:20[音乐]到这里来探索真是太好了.
4:27 Not only are we learning and carrying out our experiments but we also
4:31 get to see so much natural biodiversity that it has to offer.
4:35分的生态系统也提供了很多
4:39 of species that are not found elsewhere in Southeast Michigan,
4:42如貂或鼯鼠.
4:45 It's our job to protect it and preserve it as much as possible.
4:48我们在这里做的很多工作就是观察我们现有的物种，
4:57 they are invading the area that's really an important one.
5:01我们不是唯一有这个问题的地方，
5:04，但不是所有有这个问题的地方都有
5:07 the resources to do all the 研究 and understand the situation.
5:10我们的目标是理解这种存在的情况
并且能够将我们所学到的应用到各种各样的新情况中.
5:19[音乐]
5:25 >> We are planting a whole bunch of
5:26 native plant species to fends and wetland prairies is to try to
5:31 learn more about management practices for those types of
5:34 ecosystems as well as boost up some of the floral species.
5:38最后一步是踩它.
5:43所以你要从四面八方阻止它.
5:48 >> Without those floral species,
5:50 there are no flowers for the pollinators and without the pollinators,
5:53 there are no other species that rely on them to pollinate,
5:57，还有食物来源.
六点，所以非常重要的是，我们
6:01 out-compete some of these woody species with more flowers.
6:06 We hope that after planting a bunch of these native species and
6:10 following them for either a summer or a few summers that we will
6:13 Understand more about invasive species and fens and how those are
6:16真正影响了种植和恢复策略.
19(噪声)
6:24 >> I hope this is the first step towards a lot of similar activities in the future,
6:28我们有一个110英亩的自然保护区，
6:31 almost all of which needs some sort of restoration measure,
6:35 whether it'd be seed planting or prescribed burns or the like.
6:38我希望未来我们能做很多这样的事情.
40(音乐)
6:45 >> I think if there's anything that climate change is teaching us today,
6:49 it is that we cannot colonize every square inch of space on
6:53 the planet for human use and still expect life to thrive.
6:59我们人类不是至高无上的主人，
7:02 but interdependent collaborators in the bio-diverse community of
7:07 life whose intricate workings we're just beginning to wrap our heads around.
7:15 The bio preserves can be a school house for us in that regard.

沿着小路走到韦德体育app官网的生物保护区，看看研究和保护工作是如何抗击入侵物种的, 从与土地的联系中可以学到什么. 欲了解更多信息，请访问 奥克兰.edu/biology/preserve.
>> (音乐) Welcome to Reroot庞蒂亚克. 我们今天在密歇根州的庞蒂亚克，我们在那里有大约14英亩的土地. 我们要看看我们的一些很酷的互动项目，让我们一起去看看. 重根庞蒂亚克是501C3的非营利组织，它将废弃的建筑改造成互动空间，教授环境互动和可持续发展主题.
虽然这些植物是一些本地开花植物，有助于支持我们的生态系统, 你可以看到我们的生物保留区. 这些植物实际上不仅有助于将水渗透到这里的地下，还将水保持在地表，并利用它将水蒸腾到大气中，清洁这个地区. 这是一个绿色基础设施装置，由五大湖保护基金资助，研究绿色基础设施如何影响微塑料流入我们的环境. 我们在我们的花园里, 我们试图用她所有的装置作品向人们展示万物是如何相互联系的，万物都是一个自我再生的循环. 在这里布置我们的花园, 我们已经建立了我们的土壤生态系统，通过接种蘑菇，包括有机物质和堆肥，让它真正定居在土壤生态系统，然后我们在这里种植园艺. 然后我们把这些本地传粉植物放在边缘，这些植物的根很深，有助于吸收任何试图通过我们场地渗入地面的水和营养，也有助于任何从陆地来的植物渗入，真正滋养我们的花园. 因为这种设置是生态系统的发展，四年来我们从未给这个花园浇水. (音乐) I tell people out here that we're developing interests and awesome, 所有这些科目都是非常棒的, and how they work together and feed into each other and help each other to grow, 没有浪费. 好吧, 我第一次意识到我对环境科学和教学充满热情是在我在OU上课的时候, 我上了一些环境科学的课和Faye Hanson的永养学课，然后意识到这一点, 这就是我想做的. 每个人的学习方式都不一样，能够接触到他们所在的地方是很重要的. I think that's what we do here, is out here we don't teach people things. 我们向人们展示很酷的东西，当他们对这些东西产生兴趣时, then we show them how it's connected and help to develop a passion. Once someone has a passion for the subjects, then you can teach them anything. 很容易. (音乐)
大多数俄亥俄大学的学生都知道贝尔湖，因为它上镜的位置，你可以在课间来这里放松. But the history behind Bear Lake is far deeper than you might expect. 以下是关于熊湖你可能不知道的四件事.
结果出来了, 关于熊湖你不知道的四件事, 我敢打赌，你对它的看法一定会大不相同.
