We woke up really tired this morning since the seminars ended at 10:00pm yesterday. To make it worse, it was freezing last night and our blankets didn’t seem thick enough. The morning was still pretty cold and everyone was dressed in long sleeves and pants. The cook was very nice and made congee for breakfast considering the Chinese students staying with us. After breakfast at 8:30, we saw a deer right outside of the lodge before we met at the Boat House. Dr. Dale Kristensen was kindly here to talk about wetland assessment and identifying plant species. We walked through the Cow Island marsh trail up to Cow Island and looked at the different kinds of wetlands we encountered. We also identified a number of plant species that was found in the swamp, marsh, and ecotones that we visited. Following this, we drove to just out of QUBS to a field to look at a meadow marsh that was different from the ones this morning. This one was a palustrine wetland, which means the water from the wetland comes from the fields around it, and not the lake. We looked at the dominant plant species found at this wetland, and were also surprised to find a dried up water snake! We were all very hungry from walking all morning and had lunch back at QUBS.

In the afternoon, we took three vans and head up to Thousand Islands! Dr. Wang played really cool Chinese music in his car and the ride was approximately 40 minutes. The first thing we saw getting off the van was Captain Jack Sparrow. There were also a few gift shops and some of the Chinese students bought some post cards. After Dr. Wang got the tickets, we took a one hour cruise on the St. Lawrence waterway and saw numerous numbers of islands and ships. We saw a lot of lovely boaters waving at us. Our students took lots of pictures of the scenery and group pictures on the deck. During our cruise, we also saw the Canadian-US border that was literally a few hundred metres away. After we got back, some of the students got ice-cream and other got fish-and-chips. Unfortunately, I forgot my wallet and didn’t get anything. We drove back right on the dinner bell and everyone was pretty hungry from the busy day. In the evening at 7:30, we had four student seminars on dams in Canada and China. They were Ying Zhou, Jing Wen, Xinyi Zhao, and Wenxi Feng. They individually presented on the topics: hydro-dams, friends or foe for the economy, pros & cons of hydro-dams construction in an aquatic ecosystem in China: upper reach of Yangtze River System, costs and benefits of hydro-projects in the social-economic development in China, and finally pros & cons of hydro-dams on the middle and lower reach of the Yangtze River. After listening to their fabulous presentations, we were off to bed around 10:30pm.

 加拿大的天气真的和中国很不一样。一早耀眼的阳光透过纱窗,撒在床上,可感觉到的却是冷冷的空气,就像2,3月份中国的早春一样。大家都在这盛夏的季节穿着长袖长裤,享受着这异国他乡的早餐。8点半,大家聚集在boat house,开始了今天的行程。Dale Kristensen,是今天为我们上课的老师。我们在boat house前,兴致勃勃地听着Daniel给我们介绍optonic lake的历史,才知道,这个湖其实不是天然的,是由于大坝的控制而形成的。然后他又给我们介绍了调查湿地所应该涵盖的项目,接着带着我们认识了一些湿地里面的植物。 离开boat house,我们第三次来到了这条Cow Island marsh trail,Dale告诉我们湿地其实是有很多种类的,大致有marsh,swamp,fen和bog这四种。我们路过湿地和干地的过渡带,走过这条小路,到达cow island。一路上看见了很多湿地上生长的植物,也看见了如画般的蓝天。 10:30左右,我们坐车来到了一片田地间,这里的湿地和在之前看到的不太一样,植物也不一样。这种湿地的水是从田的周围来的而cow island湿地的水是来自于optonic的湖水。在这片湿地里面我们不光看到了一些优势种,还看到了北美的很常见的蝴蝶,红色的双翅非常美丽。临走的时候,竟然还在湿地里面发现了一条晒干的蛇! 午餐是有着酥脆外壳的quiche(非常像pie),有肉的和蘑菇口味的,奶味和茄汁味两种意面,以及照旧的三样配菜。午休期间一头母鹿光临我们station门前花坛——一头白尾鹿,这算是我们能在这个地区见到的最大型动物了,大家都很兴奋争相去拍照,那头鹿也毫不怕生,直到我们走得很近了才跑开,让我们大饱眼福。 下午的行程是去圣劳伦斯河、安大略湖游船,路上经过一座水闸,正好遇见它开闸放行,因而我们等在那看着这个二级船闸,从进闸放水到出闸的整个过程,也算是提前见识了三峡行船的过程了,虽然是微缩版的。圣劳伦斯河起于安大略湖,一路向东汇入大西洋,它也是美国与加拿大的国境线,在河上坐船游览可以见到湖岸风光,绕过湖中一个又一个盖着洋房的小岛,我们不走重复路线地在湖中兜了两圈,最后回到我们的起点。这是五天以来第一次观光、放松,大家都沉浸在湖光山色的美景中,一起谈天、嬉笑、留影,有些同学还在上岸后买了精美的明信片、美味的ice-cream,总之,这个下午我们度过的轻松而惬意。但这毕竟不是我们的主要目的,晚上四位同学就河流筑坝对生态、经济的影响进行了他们的论点阐述,并对长江三峡水电全流域影响进行了分段分析。同学们随之进行了深入的讨论,通过中加问题、案例的对比,我们期待找到更全面的认识和更好的解决问题的办法。 一天即将结束,继续为我的presentation奋斗中,这里的每一天都充实而愉快。
