Fire and spatial flowering patterns

With nearly all of our plants mapped at Staffanson, Claire and I have taken a little sneak peak at the spatial data we collected (it’s like Christmas in July, we just couldn’t wait to open our presents). I have included a graph depicting the the average distance from each flowering Echinacea plant to its kth nearest neighbor. The distribution of distances were nearly all skewed right so I plotted the natural log-transformed distances +/- the SE. There are clear differences between the East and West units (note that the East unit was burned in 2014).

Although this graph does not necessarily reflect distances to the true nearest flowering neighbors (we only included distances for plants mapped on our sampling transect), these data are consistent with our hypothesis that fire increases the density of flowering Echinacea. More to come soon…
