7 Lessons with set task, 7 assignments. Online and elearning comes with self assessment tasks.
This course is designed to follow on from Arboriculture I, however it may be taken as a stand alone short course.
TUTOR’S COMMENT “This course provides graduates with more in-depth knowledge than Arboriculture I by focusing on such topics as transplanting techniques, environmental control, environmental tolerance, and strengthening techniques, as well as felling and stump removal. The course culminates with a lesson on establishing and designing a tree plantation geared at the serious professional.” – Gavin Cole B.Sc., Psych.Cert., Cert.Garden Design, MACA, ACS Tutor.

Investigate Unique and Novel Tree Planting and Establishment Methods
Just creating a pocket or basin on a slope and using the soil removed to build a wall around it, especially on the down slope side, is what is meant by this. The wall will then hold onto the water and assist in halting soil erosion. The pocket won’t be swept away in torrential rain thanks to an overflow spillway in the wall. Before the plant takes root, the pocket might need to be periodically reformed.
Serration on a slope
Terraces can be built on sloping terrain to promote plant growth and lessen erosion. For the purpose of retaining water, slopes are divided into steps that are around 1 m by 1 m in size. The steps will crumble over time, but by that time the plants will typically have established themselves. Also, the eroding stairs’ loose soil offers good germination spots for seeds dropped by other surrounding plants.
In order to stop erosion, this method makes use of bundles of branches put on slopes. Long, thin branches are knotted together and buried partially in contoured trenches that have been dug across the hill, or the slope’s surface is simply covered in cut branches and dry vegetation.
In other instances, species that readily take root (such willows or poplars) were used to construct the wattling bundles, which later became a component of the slope stabilisation plan. A different option is occasionally adopted, particularly in nations where willows or other suckering plants that have been imported run the risk of becoming invasive weeds.
Planting in Dry Areas
Plant establishment can be quite challenging in desert, non-irrigated areas. Simple solutions to the water shortage problem include mulching, reducing weed development, spreading plants widely apart, and making saucer-shaped depressions in the soil to hold water. Moreover, smaller plants have a higher probability of establishing themselves.
In regions with clear night skies, condensation traps have also been utilised with some effectiveness. Building a planting basin with a 1.5 m diameter and a depth of 30 cm is one easy way to capture the moisture from condensation. The plant is positioned in the centre on a mound, and polythene sheeting is used to capture soil moisture that is evaporating.
Although the outcomes are less predictable than when established nursery-grown plants are transplanted, direct seeding is an affordable means of reestablishing vegetation.
The most crucial element is to get rid of weed growth before sowing to reduce competition with the seeds as they germinate. The best results come from an initial application of chemical herbicides; alternatively, cultivation can be utilised to promote the germination of dormant weed seeds, which can subsequently be sprayed. The soil can be lightly worked to create ideal germination conditions for the seed. The seed can then be dispersed either manually on small sites or mechanically using hoppers or direct drilling on bigger sites. The location has to be fenced off, and additional weed management is necessary.
Natural regeneration can produce good outcomes where there is already a cover of local vegetation. The area has to be enclosed with fencing, and the weeds on the tree’s windward side—where seeds are most likely to fall—should be pulled.
A method that is frequently utilised on places with steep slopes or restricted access is spray seeding. A slurry of water and wood cellulose components contains seeds (ie. paper, wood shavings, sawdust etc). The liquid is then sprayed onto the ground’s surface using a pump. The slurry serves as a surface for mulching protection for the seeds.
