Ecological succession part II
Storyboard Text
- Moss didn't think everything through and actually did the same mistake as lichens did thousands of years ago.Now grass, flowers and some ferns took over and have big plans for this area!
- We'll make a forest out of this place!Let's bring forth a secondary succession!
- Herbacaea plants did a great job planning that Secondary succession, now animals started living in these lands, organic matter accumulated in the soil and a century or two later and we could see shrubs all around!
- Small trees started to appear, making up a young forest, full of hope. Pioneer trees also populated these places. among these trees, the trembling aspen. They would also prepare the field for other trees to strive.
- Even us, moss and lichens have some place here!!!
- Pioneer trees are short lived, they rarely grow older than 80 years old, eventually the soil will be be in a weird state, poor of some minerals and rich with others enabling other trees, more resistant and who could wish to live longer. Like white birch, balsam fir, spruce and maples
- In that state, the boreal forest reached a state where it is called a climax community. It is ready to live like that for long, until big disturbance like diseases and forest fires come and kill trees in high number. AMany ecosystems in there are striving.
- Hey, what's the fire index today?
- Now, that was the story of the ecological succession.We can't wait to see what is coming next for our dear forest...
- No idea...
