ACTGOV High Country Bogs and Fens

This layer contains information on the distribution and vegetation types of High Country Sphagnum Bogs and Fens in the ACT as defined by Nature Conservation (High Country Bogs and Associated Fens) Conservation Advice 2019 (Nature Conservation Act). The dataset includes areas of RAMSAR significance. The threatened Northern Corroboree Frogs are also associated with these ecosystems. Veg mapping was undertaken by Geoff Hope et al in 2009 and later revisited during mapping of ACT Vegetation Communities in 2015-2018 (Baines et al 2018). The ACT Scientific Committee determined that the ecological community High Country Bogs and Associated Fens is eligible for inclusion in the ACT Threatened Ecological Communities List in 2019. Most ACT High Country Bogs and Associated Fens communities are consistent with the nationally listed Alpine Sphagnum Bogs and Associated Fens ecological community. The mountains of the Australian Capital Territory support substantial areas of peat-forming mires in interfluves and valley heads, as well as areas of riparian fen vegetation along streams. While similar fens and bogs occur in the Snowy Mountains, the ACT represents a significant outlier of major biogeographic significance because the mires are near their climatic limits and hence sensitive to climate change. Mapping of the mires was originally completed by Hope et al 2009. The mapping was developed in three stages using orthorectified aerial photography and satellite imagery and extensive field checking.

Other key plant communities (Hope et al. 2009): • Empodisma minus restiad Fen. • Phragmites – Typha tall sedgelands (Fen). Associated plant communities (Armstrong et al. 2012): • a14: Poa costiniana – Carex gaudichaudiana Subalpine Valley Grassland of the Australian Alps Bioregion (Alpine/subalpine Grasslands/Herbfields). • e59: Hakea microcarpa – Baeckea utilis – Leptospermum myrtifolium Subalpine Wet Heathland on Escarpment and Eastern Tableland Ranges of the South-Eastern Highlands Bioregion. • u193: Hakea microcarpa – Epacris breviflora – Epacris paludosa Montane Wet Heathland of the Australian Alps and western South-Eastern Highlands Bioregions. Note this product includes some areas of a33 vegetation community, which is formally considered to be associated with the threatened community (see ACT High Country Bogs and Fens Action Plan 2024, ACT Government). However, these areas were originally mapped by Hope et al 2009 with high altitude sphagnum bog (HSB) present.

However, the dataset is was updated using Near Infrared Imagery 2015 and LiDAR data in 2019. Further updates will be implemented as required if new or better mapping of bog and fen areas become available. Fit for purpose: This dataset was captured at 1:3,000 scale. This dataset is fit for use as a tool for showing presence of bogs and fens in the ACT. Exact boundaries and extents will contract and expand throughout time. This should be considered if data use purpose requires accuracy of greater than 50m.
