commonly present <strong>in</strong> current Garry oak meadow plant assemblages,<br />
which facilitated comparisons between <strong>the</strong> sites. Fur<strong>the</strong>r, we assumed<br />
<strong>the</strong>se regionally common species to be surrogates for <strong>the</strong> overall<br />
responses of native and exotic species to <strong>the</strong> various changes affect<strong>in</strong>g<br />
this system (e.g. <strong>in</strong>tense herbivory, fire suppression, <strong>in</strong>vasive plants, etc.).<br />
Figures 3 and 4 show some of <strong>the</strong> more charismatic flower<strong>in</strong>g plants we<br />
encountered dur<strong>in</strong>g our survey.<br />
We ran replicate 60 m transects parallel to <strong>the</strong> prevail<strong>in</strong>g slopes at <strong>the</strong><br />
two sites and placed 1 m 2 quadrats at 0, 20, 40, and 60 m so as to capture<br />
as much variation as possible <strong>in</strong> <strong>the</strong> vegetation at each site. We recorded<br />
<strong>the</strong> orientation of each transect us<strong>in</strong>g a compass and made sure that each<br />
quadrat was placed squarely with <strong>the</strong> transect l<strong>in</strong>e runn<strong>in</strong>g through <strong>the</strong><br />
middle. With<strong>in</strong> each quadrat we visually estimated <strong>the</strong> percent coverage<br />
of each of <strong>the</strong> six plant species us<strong>in</strong>g <strong>the</strong> Braun Blanquet cover scale<br />
