It is possible to plant Eucalyptus throughout Galicia, but you must correctly choose the species and plant according to the best silvicultural practices. Many of the early trials failed because a limited range of frost-susceptible species was used. However, the Eucalyptus genus is highly diverse, with many trees thriving at high altitudes in their native Australia (eg, the Blue Mountains and Central Tasmania), so there are many that can tolerate frost, exposure, and wet places. There are 17 species that cover everything from high-yielding lowland species to more "bulletproof" species that are probably as tolerant of extremes as any native tree.
There are two main limitations for planting Eucalyptus Globulus in Galicia:
The most important factor is the duration of low temperatures (for example, prolonged cold snaps of more than two weeks) and frosts in the off-season: they are generally not common in oceanic/low-lying sites
Adequate soil moisture
Water is the carbon building block for wood/cellulose
Although eucalyptus trees tend to be more water efficient and productive than other trees, they still need adequate supplies.
For the planting of Eucalyptus Globulus, it is important to take care of:
– Avoid places with frost
– Avoid flooded sites
Good silvicultural planning is required to match the species of origin and provenance with the:
– Latitude of the site
– Site altitude
– Broad climatic character
The alternative for places that do not meet the above requirements, it is possible to plant Eucalyptus Nitens
When establishing a eucalyptus plantation, regular silvicultural practices need to be followed in order for the trees to establish themselves successfully and thrive properly. This includes:
Site preparation before planting:
– Land cleared for planting by mechanical means.
– Mound to give a clear planting area.
– Tear up the soil to minimize compaction. (Optional).
Proper spacing (see below)
Make a hole a little bigger than the plant that covers the root, add a little topsoil or compost fertilizer (Agroblen is recommended) and then make sure that all the roots are well buried.
Use of tree covers to provide some protection and prevent damage from herbivores. (Optional, or electric shepherd).
Clearing the following year, to eliminate competition.
For long rotation forestry (10 years) involving planting Eucalyptus nitens for cerulosa, we would recommend a stocking rate of 1.666 per hectare (3 mx 2.0 m) or (3 mx 2.5 m) .
We suggest going with the smaller gaps in more exposed conditions. When planting smaller numbers of trees, it is best if the trees are planted in compact clumps leaving views, or open ground between the clumps, as this provides a microclimate. Planting isolated groups is relatively ineffective and should be avoided.
Mountain species like E.gunnii and E.coccifera are much more cold tolerant and will withstand cold winter winds. These should be planted along an exposed edge of the planting. They are useful near coastal sites as they will provide some protection from salt laden winds.
Eucalyptus trees do not tend to thrive in flooded conditions, but there are some that are better suited to wet sites, such as E. rodwayii, E. johnstonii, and E. aggregata .
Eucalyptus can mix with native trees in shelterbelts. The eucalyptus trees will tend to be the fastest growing and the backbone of the shelterbelt, while the native ones will increase biodiversity.
Galician regional regulations
Currently in Galicia it is only allowed to plant eucalyptus in areas where before +50% of the forest feet were eucalyptus, there are also limitations due to sectoral effects, but it is not the most common.
