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.


 SAMPLE COURSE NOTES - INNOVATIVE WAYS TO PLANT TREES
 

Pocket Planting

This is simply establishing a pocket or basin on a slope, with the soil excavated from the pocket being used to form a wall enclosing the pocket, particularly on the down slope side. The wall will then retain water and help prevent soil erosion occurring. An overflow spillway in the wall will prevent the pocket from being washed away in heavy rains. The pocket may need to be reformed every now and then, until the plant is established.

Slope Serration

Sloping sites can be terraced to enable plant establishment and reduce erosion. Slopes are cut into steps which measure approx. 1 m x 1 m, with the steps sloping back towards the hill to retain water. Over time, the steps will erode, however, the plants will usually have become established by then. The loose soil from the eroded steps also provides favourable germination sites for seed which is dropped from other nearby plants.

Wattling

This technique relies on the use of bunches of branches placed on slopes to prevent erosion. Bundles of long, slender branches are tied into bundles and are partially buried in contoured trenches which have been cut across the slope, or cut branches and dried brush are simply spread across the surface of the slope.

In some cases, the wattling bundles have been prepared from species which root easily (eg. willows or poplars) and which then become part of the slope stabilisation scheme. Dried brush is sometimes used as an alternative, especially in countries where introduced willows or other suckering plants are likely to become invasive weeds.

Planting Arid Sites

Plant establishment in unirrigated, arid sites can be extremely difficult. Mulching, controlling competing weed growth, wide spacing of plants and creating saucers of soil to retain water, are simple ways of overcoming the water shortage problem. Smaller-sized plants also have a better chance of becoming established.

Condensation traps have also been used with some success in areas with clear night skies. One simple method of trapping the moisture from condensation is to construct a 1.5 m diameter planting basin with a depth of 30 cm. The plant is placed on a mound in the centre and polythene sheeting is arranged to absorb evaporating soil moisture.

Direct Seeding

Direct seeding is a low cost method of re‑establishing vegetation, although the results are less predictable than transplanting established nursery‑ grown plants.

The most important factor is to eliminate weed growth before seeding to remove competition from the germinating seeds. An initial spray with chemical herbicides will give the best results; alternatively cultivation can be used to encourage dormant weed seeds to germinate which can then be sprayed. A light cultivation of the soil will also provide favourable germination conditions for the seed. Seed can then be broadcast either by hand on small sites, or by direct drilling or mechanical hoppers for larger areas. Fencing the site and follow‑up weed control is also be required.

In areas where there is an existing cover of native vegetation, natural regeneration can give good results. The site should be fenced off, and the weeds on the windward side of the tree (where seeds are most likely to drop) should be removed.

Spray Seeding

Spray seeding is a technique which is often used on sites which are steeply sloped or have limited access. Seeds are mixed into a slurry of water and wood cellulose materials (ie. paper, wood shavings, sawdust etc). Using a pump, the mixture is then sprayed onto the surface of the ground. The slurry acts to provide a protective mulching surface for the seeds.
