Hydrobiid Snail (St. Pauls River)

​Habitat

• 'Habitat’ refers to both known habitat for the species (i.e. in or near habitat where the species has been recorded) and potential habitat (i.e. areas of habitat with appropriate characteristics for the species and within the species' potential range which have not yet been adequately surveyed).
• If in doubt about whether a site represents potential habitat for this species, contact the Threatened Species Section for further advice.
• The known range of B. krybetes includes two sites on St Pauls River, in north east Tasmania (see distribution map, above). The potential range for B. krybetes may extend beyond this range. 
• Habitat for B. krybetes includes the following elements: leaf litter, woody debris and rocks in the stream channels, located on the underside of submerged material.

What to avoid

• Damage to downstream habitat through upstream agricultural and forestry practices
• Damage to stream habitat through altered flow regimes (e.g. due to land clearing, establishment of impoundments etc).

• B. krybetes is a very small, hard to find species which can be difficult to tell apart from other species of Beddomeia and some other hydrobiid species. Identification to species level normally requires a specialist.
• For further information on surveying or identifying this species, contact the Threatened Species Section.​​​​​

• ​If you live or work in the area where the species occurs (see distribution map, above), look out for and record any observations of the species. All records of this species can provide important information on distribution and abundance.
• Important! Always report any observations of the species to the NRE Natural Values Atlas, or else provide the data direct to the Threatened Species Section. Records stored on the NVA are a permanent record and are accessible to other people interested in this species.
• Consider the needs of the whole habitat. Preserving a threatened species' habitat is the best way to manage both the species and the environment in which it lives.
• For long-term protection of populations on private land – consider protection of habitat through a vegetation management agreement or conservation covenant. See the NRE Private Land Conservation Program for more details.

• ​Activities which result in habitat degradation are the principal threat to B. krybetes, including clearing of streamside vegetation.
• To avoid damage to stream habitat – do not remove streamside vegetation around known localities.
• To avoid downstream impacts – do not clear streamside vegetation upstream of known localities.

• Activities which result in habitat degradation are the principal threat to B. krybetes, including burning of streamside vegetation.
• To avoid damage to stream habitat – do not burn streamside vegetation around known localities.
• To avoid downstream impacts – do not burn streamside vegetation upstream of known localities.​

• ​Activities which result in habitat degradation are the principal threat to B. krybetes, including permanent clearing of native streamside vegetation and stock access.
• To avoid downstream impacts do not clear and convert (e.g. to pasture or plantation) streamside vegetation upstream of known localities.

Stock grazing

• To avoid damaging habitat – protect streamside habitat from stock by fencing and provide alternative access to water.

• ​Activities which result in habitat degradation are the principal threat to B. krybetes, including alterations to flow conditions within stream habitat.
• To avoid damage to stream habitat – avoid alterations to stream flow conditions, for example through construction of water impoundments upstream of known localities.

• ​Activities which result in habitat degradation are the principal threat to B. krybetes, including alterations to flow conditions within stream habitat.
• To avoid damage to stream habitat – avoid alterations to stream flow conditions, for example through construction of water impoundments upstream of the known localities.

• ​Activities which result in habitat degradation are the principal threat to B. krybetes, including pollution of the waterway. Sources of chemical pollution include pesticides and herbicides, and fertiliser runoff into waterways.
• To avoid damage to stream habitat – do not use herbicides and pesticides in the vicinity of known localities where this could lead to input of chemicals into the waterway.
• To avoid damage to stream habitat – avoid application of fertiliser in the vicinity of known localities where this could lead to runoff of fertiliser into the waterway.
