What evidence is required to demonstrate competence for this standard as a whole?

Competence in implementing revegetation works requires evidence that a site has been appropriately revegetated and maintained according to enterprise guidelines and industry best practice. The skills and knowledge required to implement revegetation works must be transferable to a range of work environments and contexts. For example, this could include different environments, plant species and revegetation techniques.

What specific knowledge is needed to achieve the performance criteria?

Knowledge and understanding are essential to apply this standard in the workplace, to transfer the skills to other contexts and to deal with unplanned events. The knowledge requirements for this unit are listed below:

Revegetation techniques.

Ecosystems, provenance and habitat requirements.

Factors affecting the timing and method of planting.

Identification of pests and diseases of trees.

Principles and methods relating to the prevention and control of pests and diseases.

Safety requirements when handling and using hazardous goods.

Nutrient requirements of a range of plant species and cultivars.

Physiology of plant growth.

Techniques for protecting and securing/anchoring trees and shrubs.

Plant selection and culture.

Soils and nutrients.

Calculations for materials.

What specific skills are needed to achieve the performance criteria?

To achieve the performance criteria, some complementary skills are required. These skills include the ability to:

Prepare equipment and materials.

Prepare a planting site.

Effect revegetation works.

Maintain revegetated site.

What processes should be applied to this competency standard?

There are a number of processes that are learnt throughout work and life, which are required in all jobs. They are fundamental processes and generally transferable to other work functions. Some of these are covered by the key competencies, although others may be added. The questions below highlight how these processes are applied in this competency standard. Following each question a number in brackets indicates the level to which the key competency needs to be demonstrated where 0 = not required, 1 = perform the process, 2 = perform and administer the process and 3 = perform, administer and design the process.

1. How can communication of ideas and information (2) be applied?

Inform fellow workers of works.

2. How can information be collected, analysed and organised (2)?

Schedule of works.

3. How are activities planned and organised (2)?

Equipment, machinery and materials.

4. How can team work (2) be applied?

Carrying out revegetation works.

5. How can the use of mathematical ideas and techniques (1) be applied?

Calculation of materials.

6. How can problem-solving skills (2) be applied?

Defects in materials, problems requiring remedial action.

7. How can the use of technology (2) be applied?

Tools and equipment.

Are there other competency standards that could be assessed with this one?

This competency standard could be assessed on its own or in combination with other competencies relevant to the job function.

For information about assessing this competency standard for consistent performance and where and how it may be assessed, refer to the Assessment Guidelines for this Training Package.

Range of Variables

The Range of Variables defines the different contexts, work environments and parameters governing the performance of this competency standard. The variables chosen in training and assessment will need to reflect local industry and regional contexts

What sorts of site conditions may be included?

Soil types, moisture content, pH levels, salinity, texture, compaction, aspect, pollutants, toxicity, climate, buildings, road works and shade.

Which species selected may be relevant to this standard?

Native and exotic plants.

Which plant materials might be included?

Seedlings, seeds, cuttings, divisions, bulbs, corms, rhizomes, or transplanted stock.

Which establishment methods may be used?

Hand planting, mechanical planting, direct seeding, encouragement of natural regeneration, mechanical sowing and fire.

Which forms of earthworks may be considered?

Irrigation, drainage, ripping, cultivating and clearing debris.

What sorts of growing requirements may be included?

Time of planting, pruning, depth and drainage.

How might maintenance be undertaken?

By watering, mulching, fertilising, protection, staking and weeding.

Which protective structures might be included?

Signs, fences, barriers, cloches, stakes and mulches.
