Each application contains a species distribution layer and, where available, various supporting layers that the user may or may not choose to use. Each layer can be turned on and off as required. The details for each layer are provided below.
"Species Name" - this layer shows the current distribution that has been deliniated for the bat species. It will be updated as approved changes are recieved.

If you have relevant spatial data for one or more species, please advise and they can be added to the corrosponding species application.
Basic instructions for amending and submitting distributions
3. Drawing Tool
Use this tool to draw your suggested amendments to the species distribution map. Alternatively you can save the map as an image and use your personal image editing software to add amendments. Below is an example of how you might amend a map.
4. Print Tool
Use this tool to save your map as an image. Alternatively save a screen grab. On saved, send your image to firstname.lastname@example.org.
Use these tools or your mouse or touch controls to navigate your map.
6. Full Screen
Expand your map to full screen.
To utilize the extensive knowlege of the ABS to develop and maintain 'best knowledge' (aka 'expert') distribution maps for all Australialian (and New Zealand?) bat species, and to make those maps freely available.
An authoritative, comprehensive and freely available set of species distributions maps will ultimatly contribute to the conservation of bats. This can be achived through a variety of means:
Assist researches and managers with the validation of bat species spatial records for the purpose of scientific analysis, environmental and threatened species assessments, development of management and action plans.
Publication in relevant books, reports, educational material and websites.
Assist with species identifications based on spatial location.
1. Using one of the species mapping applications (see below), users review the species distribution map and draw their recommended amendments.
2. Amendments are submitted and reviewed by the nominated expert for the species.
3. If accepted, map is updated, made available and user is advised. Otherwise any issues are discussed until resolved.
SPECIES MAPPING APPLICATIONS
Below are the links to each of the species mapping applications.
There are four categories that may be used when defining a species distribution. 'Current Range' is the only required category. The other categories are optional and may be delineated based on the best available knowledge.
Current Range - area where the species is currently known or thought to occur. This is what you would see on a typical published species
Possible Range - area where the species may occur however there is some doubt that it actually occurs there. Any records of a species should
be verifiable evidence
Previous Range - where the species use to occur but it is known to no longer occur there.
Vagrant or Outier - confirmed or known records of individuals of the species outside the current range.
At what scale should species boundaries defined? For many bat species distributions are poorly known therefore boundaries can only be defined at very large scales (greater than 1:1,000,000). For a small number species however, distributional patterns are well understood (e.g. rainforest or riparian dependent species). But even for these species individuals will, on occasions, traverse or utilize features in the landscape that are not considered typical for the species. Therefore species boundaries should be delineated at the smallest scale possible, however deliniation of distributions around fine scale landscape features such as riparian strips or small patches of vegetation is likely to be considered too small (roughly 1:100,000 or when the scale bar reads 5km)
