Figure 2-2: Native and Exotic Diversity for Each Monitoring Plot
Figure 2-3 below illustrates changes in the percentages of native species diversity within
the monitoring plots. Since 2006, most plots have shown an overall small decrease in
native species percentage, with the greatest decrease being within V2-B1 going from 50%
native species diversity in 2006 to 33% in 2011. Whilst V14-A1 also had a notable
decrease across the survey seasons (16% decrease), the percentage of native species
diversity remains high at 84%. One monitoring plot, namely V5-B4, has had an equally
large increase in the percentage of native species diversity, with an increase of 14% since
monitoring began in 2008.
Only one site has been recorded as consistently reducing in native species diversity
percentage from season to season, namely V10-A1, however the actual percentage of
native species diversity remains high at 86% in 2011. All other monitoring plots show
mostly small variations in species diversity.
