- Introduction
-
I began wetland researches after an overseas survey in the Sichuan Province of China, 1988. I was surprised when I knew that I had never written about wetlands in Japan until 2003. I think this is not so good when I knew this fact. So, I began wetland researches in Japan in 1995. The study site is Otanoshike wetland in Kushiro, eastern Hokkaido. But, that was a simple survey, i.e., the measurements of vegetation only.
Thereafter, we measured methane flux in a Siberian wetland. I talk about wetlands sometimes in my lectures, and at that time I feel that the importance of wetland again and again, to protect nature. - A start
-
That was an annual meeting of Ecological Society of Japan at Hokkaido Branch. I was 1st grade of doctoral course.
Prof. K of H University at K asked me: "You wanna go China?"
I: I promptly replied, "Sure."In the summer of that year, I was on the largest wetland in China.
Center: Umeda (leader) and Tsujii (sub-leader) We went to the research site by riding horse once. Somebody fell off his horse.
Wetlands I have ever researched
Wetlands of which researches have been published
- China
-
Ruoergai grassy marshland
Ruoergai marshes, Ruoergai prairie
This is the start of my wetland research.
Research summary: read "Tsuyuzaki, S., Urano, S. & Tsujii, T. 1990. Vegetation of alpine marshland and its neighboring areas, northern part of Sichuan Province, China. Vegetatio 88: 79-86".
Yak and its effects on vegetation (Tsuyuzaki, S. & Tsujii, T. 1990)
Characteristics of Carex meyeriana tussock (Tsuyuzaki, S. & Tsujii, T. 1992)
Microtopography and plant establishment
That's all I did in Ruoergai.
Sandaohu wetland
The research was postponed, due to Tiananmen massacre taking place in the year (1989). The first plan was going in summer, but we went in the season with leaf fall. It was cold, and most herbs were withered.
I measured Larix (larch) and Betula (birch), because I could not do anything more (Tsuyuzaki 1994). - USA
-
Wetlands and hot springs near Spirit Lake on Mount St. Helens
Measured seedbank in the wetland by Mandy and Jon (Tu et al. 1998)
I walked for a half of day, because I lost my way, (not for finding out wetlands, though).
I remembered somebody said, "This is science!"Alaska
We started revegetation patterns on Piceae mariata forests after severe wildfire in 2005. The progressive summary will be shown in a page "Fire Ecology".
In 2006, we went to ANWR (Arctic National Wildlife Refuge) where permafrost is distributed. We measured vegetation on and around palsas in the tundra (Tsuyuzaki et al. 2008). - Siberia
-
Kolyma River in Sakha Republic - I went to Siberia twice, and this survey was conducted in the first year.
Measured the relationships between methane flux and vetation types near Kolyma River.
Vegetation patterns in gullies developed by melting ice wedge
[Left] Kolyma River taken from a boat. We can see a sparse larch forest. [Right] A gully surveyed. (Tsuyuzaki et al. 1999)A mosquito came into my eye. It was in imminent danger, because we might not return by the coast covered with floating ice. Then, I got Dr. Sato's wise remarks, "The nature of Siberia has been kept by mosquitoes." At that time, I wanted to say "Give me job, if you feel...". Everbody said my shoulder was crying. Certainly, nothing was good when I went back the university.
Keywords to understand Alaskan and Siberian wetlands
permafrost and its related topography, such as:
polygon, yedoma, ice wedge, palsa, pingo, baidzharakh
- Indonesia
-
Tropical peatland - What is this? Anyway, the jobs have been summarized by Mirmanto et al. (2003) and Nishimura et al. (2007).
- Japan (Hokkaido)
-
The volcano Mount Usu
Wetland developed in the 4th Crater on Mount Usu in the 1977-78 eruptions is very quick and fast (Tsuyuzaki 1999).
Otanoshike marshland in Kushiro Mire
We show the importance of scale-dependent environmental factors (Tsuyuzaki et al. 2004).
Hotoke Swamp
Basically, the researches were conducted by Kimura. We found out a huge seedbank in the swmap after a prescribed fire.
Now, working
- Canada
-
I can not find out any photos that show Canadian wetlands. I guess this job will have not been published, perhaps forever).
- Japan (Hokkaido)
-
Sarobetsu, northen Hokkaido
Research site in Sarobetsu wetland. A weather station is established close from here. We can see a weathercock is spinning.
Keywords related to research in Sarobetsu mire
succession
nutrient
seedbank development
tussock
litter decomposition
