Department of Science, Information Technology and Innovation BioCondition Benchmarks for Regional Ecosystem Condition Assessment Benchmarks are quantitative values for each vegetation condition attribute assessed in BioCondition (Eyre et al. 2015), and are used as a reference for comparison purposes within and between regional ecosystems. Benchmarks are subject to regular review and updates based on additional data. BioCondition benchmarks are compiled from quantitative site data from reference sites, data from the Queensland Herbarium’s CORVEG database and expert opinion, and are specific to each regional ecosystem vegetation community. BioCondition benchmarks aim to reflect the natural variability in structure and floristic composition under a range of climatic and natural disturbance regimes throughout the geographic extent of a regional ecosystem. However, data from local reference sites should be collected where possible to account for spatial and temporal (seasonal and annual) variability when undertaking BioCondition assessments. In some rangeland ecosystems, seasonal conditions can account for wide variation in the values obtained for some attributes assessed in BioCondition. Therefore in these ecosystems a range is expressed instead of a single benchmark value. When using rangeland regional ecosystem benchmarks to assess condition, the lower value of the benchmark range can be used as the benchmark, or if assessing a site under good seasonal conditions then use of the average value as the benchmark.

BioCondition Benchmarks for Regional Ecosystem Condition Assessment

Benchmarks are quantitative values for each vegetation condition attribute assessed in BioCondition (Eyre et al. 2015), and

are used as a reference for comparison purposes within and between regional ecosystems. Benchmarks are subject to

regular review and updates based on additional data.

BioCondition benchmarks are compiled from quantitative site data from reference sites, data from the Queensland

Herbarium’s CORVEG database and expert opinion, and are specific to each regional ecosystem vegetation community.

BioCondition benchmarks aim to reflect the natural variability in structure and floristic composition under a range of climatic

and natural disturbance regimes throughout the geographic extent of a regional ecosystem. However, data from local

reference sites should be collected where possible to account for spatial and temporal (seasonal and annual) variability

when undertaking BioCondition assessments.

In some rangeland ecosystems, seasonal conditions can account for wide variation in the values obtained for someattributes assessed in BioCondition. Therefore in these ecosystems a range is expressed instead of a single benchmarkvalue. When using rangeland regional ecosystem benchmarks to assess condition, the lower value of the benchmark rangecan be used as the benchmark, or if assessing a site under good seasonal conditions then use of the average value as thebenchmark.

Native plant species richness The number of species expected in four life form groups, i.e. tree, shrub, grass,forbs and other species

Tree strata:

• Sub-canopy

• Large trees

A tree is defined as a woody plant, single stemmed >2 m tall.

• Typical tree species

Shrub strata:

• Native shrub cover

A shrub is defined as a woody plant, multi-stemmed from base or singlestemmed and <2 m tall.

• Cover - percentage cover (assessed as opaque crowns)

• Typical shrub species

Ground cover:

• Native perennial grass cover

• Litter cover

• Cover – percentage cover (assessed as projected foliage cover)

• Typical ground cover species

Coarse woody debris • Total length in metres of woody debris > 10 cm diameter and > 0.5 mper hectare

Non-native plant cover • Cover – The percentage cover of non-native plants

• Typical non-native species listed with common names and declaredpest status1

Selected typical species are those that characterize the ecosystem, community or stratum at reference sites. Up to five frequently occurring species for each stratum are selected. Users should refer to the regional ecosystem description database (REDD) and/or the technical description for more complete lists of characteristic species. Only the most frequently used common name is given. Other common names may be used in other regions. Declared pest species in Queensland are designated (^).
