    • Salination
    • Erosion
    • Mining
    • Grazing
    • Vegetation harvesting
    • Pests
    • Reduction of biodiversity
    • Soil contamination
    • Urbanisation.
  • Compare the effectiveness of different policy approaches to land rehabilitation by different agencies and organisation, including:
    • Different levels of government
    • Mining companies
    • Developers
    • Conservation groups (i.e. tree planting bodies, landcare groups).
  • Develop a risk analysis for a specified site to be rehabilitated, by determining a variety of plant health problems which may impact on the success of plant establishment.
  • Analyse the failure of plants to grow successfully on a visited land rehabilitation site.
  • Develop a procedure to enhance the success rate of land rehabilitation plantings on a degraded site visited by you.
  • Describe the use of mulches, to maximise plant condition in a specified land rehabilitation tree planting project.
  • Explain different processes of establishing seedlings on land rehabilitation sites, including:
    • tubestock nursery production
    • direct seeding
    • pre-germinated bare rooted seedlings.
  • Determine factors which affect the viability of establishing five different species of plant seedlings, from five different plant families; on a specific degraded site.
  • Compare the benefits of acquiring plants for a project by buying tubestock, with propagating and growing on, or close to, the planting site, with reference to:
    • costs
    • plant quality
    • local suitability
    • management.
  • Prepare production schedules for a plant species, using different propagation techniques, summarising all important tasks from collection of seed to planting out of the tubestock.
  • Calculate the cost of production for a tubestock plant, according to the production schedule developed by you.
  • Estimate the differences in per plant establishment costs, for tubestock, compared with direct seeding methods, for planting on a degraded site.
  • Describe three different methods of planting trees for rehabilitation purposes.
  • Describe different plant establishment techniques, including:
    • wind protection
    • frost protection
    • pest control
    • water management
    • weed management.
  • Describe an appropriate method for preparing soil for planting, at a proposed land rehabilitation site in your locality.
  • Evaluate plant establishment techniques used by two different land rehabilitation programs inspected by you at least twelve months after planting was carried out.
  • Determine the needs of plants after planting, on two different proposed land rehabilitation sites.
  • Describe two different, efficient ways, of catering to the needs of large numbers of plants after planting.
  • Collect pressed specimens or photographs of twenty trees for a herbarium of suitable trees for rehabilitation, and including information on the culture and care of each tree.
  • Describe different types of soil degradation, detected in your locality.
  • Determine the risk factors involved in soil degradation, relevant to your locality.
  • Compare two different alternative methods of treating each of three different soil degradation problems identified and inspected by you.
  • Develop an assessment form to use for evaluating the sensitivity of a site to land degradation.
  • Evaluate a site showing signs of degradation, selected by you, using the assessment form you developed.
  • Plan a rehabilitation program for the degraded site you evaluated, including
    • a two year schedule of work to be completed
    • list of quantity and type of materials required
    • approximate cost estimates.
  • Explain the effect six different plant species may have resisting soil degradation.
  • Explain how different plants can have different impacts upon the chemistry of their environment, including both air and soil.
  • Evaluate the significance of a group of plants, to the nature of the microclimate in which you find them growing.
  • Compare the appropriateness of twenty different plant species for different degraded sites.
  • Determine five plant varieties, suited to each of six different degradation situations.

ARBORICULTURE/TREES/SHRUBS EBOOKS

We also offer a range of eBooks that may be of interest to you. Please visit our online horticulture bookstore.  

You may find the following of particular interest –

Growing Conifers eBook - The great thing about conifers is they look good all year round. Most of them are grown for foliage, and in general, foliage remains the same pretty well all year. Unlike other trees and shrubs, you do not have a month of attractive flowers, followed by an obscure plant the remainder of the year. A brilliant blue of gold foliage conifer will be blue or gold month in, month out.

Growing Trees and Shrubs in Small Gardens eBook - This eBook is an essential guide for anyone who wants to make the most of a small garden, balcony, veranda or courtyard. The psychological benefits of having living plants in your environment can not be underestimated. If you live in a city, an apartment or just a small cottage this eBook will help you re-connect with nature and make the most of your garden.

Trees and Shrubs eBook - Useful for students, or the tradesman already working in the field; or the home gardener; who needs a quick reference when choosing plants for a garden.

Trees and Shrubs For Warm Places eBook - Never before published! This eBook is a major reference work, 15 years in preparation, containing around 300 colour photos! It is a comprehensive guide to plants grown in any type of warm place – tropical, sub-tropical, greenhouses, and court yards that have become heat traps in temperate places.
