29. I added 200 seeds to obtain accurate per capita demographic rates. To prevent seedlings from interfering with one another, I thinned them on the 12 July 1999 and 1 August 1999 sampling dates. I thus calculated the proportion of successful seeds as (proportion that germinated and survived to 12 July) x (proportion of the 12 July unthinned surviving to 1 August) x (proportion of the 1 August unthinned surviving to 3 October).
30. Total cover, the sum of each species' cover, can exceed 100% because species' canopies overlap.

36. I added seeds of Agrostis and Plantago to 190 tussocks using the same selection criteria as for the pattern tussocks. I added Cirsium to a subset (50) of these tussocks, and fewer seeds per tussock, because I had fewer seeds of this species. Seedlings were followed using the same procedures as in the diversity manipulation experiment. Seedling size yielded similar results to the proportion of successful propagules.
