We are being asked to imagine how succession will occur on a two -acre, abandoned college lawn on your college campus, wherever that is.
00:16
And we're being asked to think about it with respect to the traits of the species that are going to occur on our succeeding lawn, the types of interactions that we might see, and then also the history of the history of, the lawn itself.
00:33
How should the history of the lawn or maybe the site of your college affect what's going to happen on your successional college lawn? so by traits, we're asked first to think about early successional traits.
00:52
And keep in mind that most early successional species are weedy species, which means that they have rapid reproduction, and they grow quickly and they're good dispersers.
01:06
So grow fast and good dispersers.
01:17
So these are species that would get to your lawn first and would start to grow up through whatever grass you have growing.
01:27
Maybe they would be things like small shrubs, for example, that might grow up there.
01:33
In terms of interactions, remember that species interactors, succession so you can have something like facilitation occurring in facilitation one species or a group of species alter the environment to make it better for later successional species so for example it might be that shade is produced by early successional species and that allows later successional species to germinate because they may need shady conditions to to germinate and to grow.

So later successional species...
