There is one application for each species of bat. Each application will contain a species distribution layer and, where available, various supporting layers for that species 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" - the current distribution of the given bat species.
Model (Dept Env, 2019) - models of the distribution of species related to the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). Full reference provided below.
Model (JCU, 2018) - models of the distribution of selected northern Australia species developed by James Cook University. Full reference provided below.
Model (Milne, 2018) - models of the distribution od Australian bat speices developed by Damian Milne. Full reference provided below.

Bioregions - Web mapping service (WMS) for the Interim Biogeographic Regionalisation for Australia (IBRA), Version 7 (Regions)

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. Amendmends don't have to be pretty, just understandable. Below is an example of how you might amendment your map.
4. Print Tool
Use this tool to save your map as an image. Alternatively save a screen grab. Once saved, send your image to email@example.com.
Use these tools or your devices mouse or touch controls to navigate around your map.
6. Full Screen
Expand your map to full screen.
To utilize ABS and the extensive knowledge of its members to develop and maintain 'best knowledge' (aka 'expert') distribution maps for all Australasian (and New Zealand?) bat species, and to make those maps freely available.
An authoritative, comprehensive and freely available set of species distributions maps will contribute to the conservation of bats. This is because there are multiple uses that the maps can and will be used for including:
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 the user is notified once the changes are made. If any issues are identified, they are discussed until resolved.
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 the area that you would typically see on a distribution map in a natural history publication.
Possible Range - area where the species may occur however it is unclear that it actually occurs there. Current records are doubtful. Any records of a species from this area should be associated with some form of verifiable evidence.
Previous Range - where the species use to occur but it is known to no longer occur there.
Vagrant or Outlier - confirmed or known records of individuals of the species outside the current range.
At what scale should species boundaries be defined at? 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 delineation 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 in the application reads 5km).
