Within-species comparison

To compare tree height and survival data, choose the experiment, species, provenance and age(s) and then navigate through the avaliable tabs:


Loading...

Average tree height: Box plots showing the median annual tree height (horizontal line) for each replicate (plot) of the selected provenance, species and experiment. Hinges show the first and third quantiles while whiskers show largest and smallest values (excluding outliers) while outliers are indicated by points beyond the whiskers. The experimental plot numbers are labelled above each figure.

Loading...

Annual tree survival: Bar graphs showing the number of trees alive in each replicate (plot) over time for the selected provenance, species and experiment. Each plot was establish with 49 trees in a 7x7 tree grid. Note that these data are for the origninally planted 49 trees only and do not include replacement or 'beatup' trees. The experimental plot numbers are labelled above each figure.

Loading...

Individual tree height: Thin lines show the annual height of individual trees of the selected provenance, species and experiment over the selected time period. The thick line shows the mean height at a given age while the shaded area displays 1SD. Note that both individual and mean tree height may appear to decrease from one age to another due to tree damage or mortality.


Between-species comparison

To compare tree height between species, select an experiment and age:

Loading...

Average tree height: Box plots showing the median annual tree height for each species (across all provenances present in that experiment and all replicates of those provenances) in the selected experiment and age. Hinges show the first and third quantiles while whiskers show largest and smallest values (excluding outliers) while outliers are indicated by points beyond the whiskers.


Between-provenance comparison

To compare tree height between provenance, select an experiment, species and age:

Loading...

Average tree height: Box plots showing the median annual tree height for each provenance (across all provenances present in that experiment and all replicates of those provenances) in the selected experiment and age. Hinges show the first and third quantiles while whiskers show largest and smallest values (excluding outliers) while outliers are indicated by points beyond the whiskers.


Between-site comparison

To compare tree height between experiments, choose a species and age

Loading...

Average tree height: Box plots showing the median annual tree height for the selected species in each experiment that they exist, in the selected age (across all provenances of that species present in each experiment and all replicates of those provenances). Hinges show the first and third quantiles while whiskers show largest and smallest values (excluding outliers) while outliers are indicated by points beyond the whiskers.
