We will describe changes in
the spatial distribution of
over nine years in a 1ha area in Buckinghamshire. Flowering spikes have been located to
within a few cm in each year
, allowing us to estimate levels of reflowering and dormancy. Comparisons of new flowering individuals with flowering locations five or more years earlier provide insights into
the colonization rates of
. These results will be discussed in the light of spatial changes across Britain. The dormancy and reflowering data will also be considered with respect to our previous work on temporal population dynamics.
