Elements and Performance Criteria
Range Statement
Performance Evidence
The candidate must produce a report of the tree identification, selection and specification process that recommends tree species for a site and incorporates the tree selections into a database of tree specimens and characteristics. The candidate must be assessed on their ability to integrate and apply the performance requirements of this unit in a workplace setting. Performance must be demonstrated consistently over time and in a suitable range of contexts.
The candidate must provide evidence for and demonstrate:consulting client, developing a brief and gaining agreementundertaking site inspection according to the client briefdetermine legislative requirements, regulatory requirements and requirements of Australian Standards including AS 2303, AS 2223 and AS 3743determining functional life expectancy of site and plantingsdetermining tree function for the precise location within the planconfirming that species and cultivar selection is appropriate for the aspect and site dimensionsresearching trees suitable for the intended purpose using multiple reference sourcesidentifying trees suitable for the intended purpose using multiple reference sources and use of taxonomic keysgiving consideration to tree morphology, physiology and ethnobotany in the identification of suitable treesestimating planting area dimensions for the tree species or cultivarconfirming that soil volume is proportioned to the size of tree in consideration and assess soil for suitability as a growth mediumconsidering environmental conditions including site hydrology for the functional characteristics of the tree and apply findingsevaluating soils, soil mixes and growing media for density, organic content, nutrient status, and physical and chemical properties appraising a wide range of soils, soil mixes and growing mediamaking recommendations for soil, soil mix and growth medium improvements by determining soil suitability for intended purposeevaluating trees from an extensive range of trees common in the regionselecting trees in accordance with suitability for the intended purpose as quality criterionevaluating and document the rationale for tree selectionrecommending tree species or cultivars for replacement or new plantingsdocumenting tree selections, selection criteria and notes on quality expectations as specificationsincorporating determined criteria for size of stock selection into the specificationsmatching species and cultivars appropriately to the determined selection criteria for species-specific characteristicsevaluating selection criteria for mature trees against capability for transplanted treesassessing final selections against the specified soil, site location and client brief and confirm the tree specificationinspecting selected plants on site for structural quality, root health and quantities according to the specificationsinspecting delivered materials, soils and growing media on site for quality assurance in accordance with the specificationsrecording quality checks on delivered plants and productscompiling tree selections into a database of tree specimens and characteristics based on tree taxonomy and nomenclature, and suitability characteristicsproducing a report of the identification, selection and specification process and incorporate the correlated recordspresenting the client or organisation with the report.
