The Certificate in Horticulture (Nature Park Management) is a vocationally oriented and IARC accredited course comprising both studies in both general horticulture and in nature park management.

Certificate in Horticulture involves the areas of work:

  • CORE STUDIES - see below
  • STREAM STUDIES - a further three modules (see below)


Students must complete and pass all of these core units.

1. Introduction to plants         

The purpose of this study area is to explain the binomial system of plant classification and demonstrate identification of plant species through the ability of using botanical descriptions for leaf shapes and flowers.


*Describe the relevant identifying physical features of flowering ornamental plants.

*Demonstrate how to use prescribed reference books and other resources to gain relevant information.

*Dissect, draw and label two different flowers.

*Collect and identify the shapes of different leaves.

*Demonstrate how to identify between family, genus, species, variety and cultivar.

2. Plant culture                       

The purpose of this study area is to demonstrate the ability to care for plants so as to maintain optimum growth and health while considering pruning, planting, and irrigation.


  • Describe how to prune different plants.
  • Demonstrate how to cut wood correctly, on the correct angle and section of the stem.
  • Describe how to plant a plant.
  • Demonstrate an awareness of different irrigation equipment, sprinklers, pumps and turf systems available by listing their comparative advantages and disadvantages.

  • List factors that should be considered when comparing types of machinery for use in garden maintenance.

3. Soils and plant nutrition     

The purpose of this study area is to provide students with the skills and knowledge to identify, work with, and improve the soil condition and potting mixes, and to evaluate fertilisers for use in landscape jobs to maximize plant growth.


  • Describe the soil types commonly found in plant culture in terms of texture, structure and water-holding and nutrient holding capacity.

5. Identification and use of plants       

The purpose of this study area is to improve the student's range of plant knowledge and the plant use in landscaping and the ornamental garden, and the appreciation of the different optimum and preferred growing conditions for different plants.


  • Select plants appropriate for growing in different climates.
  • Select plants appropriate to use for shade, windbreaks, as a feature, and for various aesthetic effects.
  • Categorise priorities which effect selection of plants for an ornamental garden.
  • Explain the differences in the way plants perform in different microclimates within the same area.

6. Pests, diseases and weeds 

The purpose of this study area is develop the student’s ability to identify, describe and control a variety of pests, diseases and weeds in ornamental situation, and to describe safety procedures when using agricultural chemicals.


  • Explain in general terms the principles of pest, disease and weed control and the ecological (biological) approach to such control.
  • Explain the host‑pathogen‑environment concept.
  • Describe a variety of pesticides for control of pests, diseases and weeds of ornamental plants in terms of their active constituents, application methods, timing and rates, and safety procedures.
  • Photograph or prepare specimens, identify and recommend control practices for at least five insect pests of ornamental plants.
  • Photograph, sketch or prepare samples, identify and recommend control practices for three non‑insect ornamental plant health problems (e.g. fungal, viral, bacterial).
  • Describe the major ways in which diseases (fungal, viral, bacterial and nematode) affect turf, the life cycle features that cause them to become a serious problem to turf culture and the methods available for their control.
  • Identify, describe and recommend treatment for three different weed problems.
  • Collect, press, mount and identify a collection of ten different weeds, and recommend chemical and  non-chemical treatments which may be used to control each.
  • List and compare the relative advantages and disadvantages of different weed control methods.

Developing Areas to Support Wildlife

Large areas of indigenous vegetation have been cleared for housing, agriculture, industry, and other uses, hence greatly reduced habitat left for native wildlife. Many of these native vegetation fragments are often small and isolated from one another by barriers such as open pasture, housing, roads, and water bodies (e.g. dams). These are sometimes known as "island" habitats. The size of an island habitat greatly determines the likely success or otherwise of the species that reside there. Genetic pools are restricted within a small habitat that can lead to problems of diversity within a species. Larger animals, especially predators are known to be severely impacted upon when habitats shrink. 

Wildlife constantly moves:

  • Looking for food; new sources; seasonal availability
  •  Looking for shelter/protection
  •  Searching for mates
  •  Dispersal of young to new ranges

In island habitats there may be no adjacent habitat to forage in, or to disperse along.

Island communities:

  • Are vulnerable to catastrophic events, such as pests, diseases, clearing, bush fires, and to gradual changes, such as inbreeding or climatic variation;
  • May not provide all the resources a species require (e.g. food, water, shelter/protection and breeding).

Links between such isolated communities would:

  • Allow migration to replenish a declining wildlife population (increasing numbers giving better chance for some to survive and reduce inbreeding).
  • Allow re-colonisation where a species may have become locally extinct (extend the local range).

Other Benefits

There are not only benefits for indigenous vegetation and wildlife, but also considerable benefits to local land owners. Creating such corridors can also:

  •  Help reduce erosion (e.g. in gullies, stream banks, on exposed ridges).
  •  Help reduce salinity problems
  • Reduce nutrient runoff into streams.
  • Provide windbreaks or shelter belts for stock and crops; this greatly improves yields due to reduced heat or cold stress of stock and lessens wind damage to plants (e.g. young seedlings, flowers on fruiting plants).
  •  Increase birth rates of animals.
  •  Provide timber and firewood.
  • Stream-line corridors help improve water quality, help mitigate floods, reduce erosion and improve recreational fishing.
