**Eucalyptus Soil Conservation**
The objective was to determine which seedlots in a species are best for soil conservation in seasonally dry hill country. Determination is found by measurement of height, diameter by height, survival, and other contributing factors.
It is important to note that eucalypt trial methods changed over time; earlier trials included mostly 15 - 30cm tall seedling grown in peat plots and the later trials have included mostly three replications of eight trees grown. This change may contribute to less significant results.
Experimental data recording procedures which require noting include:
- instances with no data recorded due to experimental recording procedures
require that the absence of a species from one replicate at a site was
treated as a missing value, but if absent from two or more replicates at a
site the species was excluded from the site's analyses.
- missing data for survival, vigour, insect resistance, stem form, crown form
and utility especially for the data recorded at the Morea Station; this
could indicate the death of species in these areas or a lack in collection
of data.
