Tony Hastings, Environmental Consultant, is currently completing Biodiversity Assessment Method (BAM) accreditation. At this stage, I can offer to quote, complete the background assessment, complete the field work and have the report ready to sign as soon as accreditation is gained.
The process can be summarised as:
1/ completing background assessment on the desktop, using existing data such as the Biodiversity Values map, Wetlands map, vegetation mapping, Bionet wildlife atlas of threatened species records, IBRA region & sub-region maps, Local Environmental Policy (LEP) layers, aerial imagery and more.
2/ conducting a quick site assessment, to verify which parts of the site and surrounding landscape are native or exotic vegetation, boundaries of vegetation communities, exact location of proposed developments and an overview of species present
3/ complete detailed surveys according to the BAM; each plot includes a 20 x 20m floristic survey, a 20 x 50m attribute survey (tree count, log count, litter count) and assesses the site context. The number of plots required depends on the size of each patch being assessed.
4/ detailed mapping and report writing, including calculating biodiversity credits
The cost and time involved depends mostly on the size of the site. A site rich in habitat values may also require targeted surveys for specific species, and these need to be completed at the appropriate time of year for that species. For example, when the plant is in flower, or when the animal is calling.
