Title
Collect, prepare and preserve plant specimens
Unit code
RTD2004A
HSC Requirements
and Advice
HSC Indicative Hours
This competency standard covers the process of collecting and preserving plant specimens for recording or
identification purposes. It requires the ability to collect appropriate plant specimens, prepare and preserve them
and to record data. Collecting, preparing and preserving plant specimens requires knowledge of plant lifecycles,
plant recognition, simple taxonomic keys, and legislative limitations on the collection of flora including
threatened species.

Evidence Guide
What evidence is required to demonstrate competence for this standard as a whole?
Competence in collecting, preparing and preserving plant specimens requires evidence that plants have been appropriately collected, preserved and
catalogued to enterprise standards. The skills and knowledge required to collect, prepare and preserve plant specimens must be transferable to a range
of work environments and contexts. For example, this could include different plants from other areas.
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:
 recognition of plants to be
collected
 legislative limitations on the
collection of flora (including
threatened species).
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:
 collect specimen
 press plant
 record and catalogue data.
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.

Individual specimens are clearly
identified in a manner that allows
them to be linked to observations.
Samples are protected from wilting
until pressing following enterprise
procedures.
Specimens are arranged on sheets

Learning experiences for the HSC must address:
Appropriate tagging and identification of specimens
including:
 recording the collector’s number on individual
specimen tags
 felt tip pen for wood samples
 pencil as tag makers
 pens will become illegible if specimens are
treated with alcohol before drying.
How will preservation be carried out?
Learning experiences for the HSC must address:
Preservation methods will vary according to
plant habit and size, as well as enterprise
procedures.
Processes to prevent wilting including:
 transporting specimens in moist polythene or
paper bags
 pressing specimens with minimum delay after
collection.
Learning experiences for the HSC must address
Pressing procedures including:
 trim shoots from excessively twiggy shrubs
 arranging specimens in newspaper ensuring
plant structures do not overlap
 arrangements for specimens larger than the
herbarium sheet
 arrangements to show upper and lower surfaces
of leaves and fronds.
Purposes of pressing:

slow drying to prevent loss of form and colour

preserve the specimen from decay

assist in presentation of specimen
