The science shows that forestry activity - especially clearfelling and monoculture eucalyptus or pine plantations - increase the fire risk. One more thing that you cannot teach people who are determined not to learn.

Climate change has been moving up on us. A little more each year, but getting a larger change each year.
Some data from some other islands ..
https://www.abc.net.au/news/2019-02-11/ ... s/10788932

"The island is in the grip of a drought, the worst in many years according to many people," Norfolk Island Mayor Robin Adams said.
Bureau of Meteorology Norfolk Island station officer, Adam Jauczius said there had been an "incredible influx of dry years" over the past 40 years. "The general trend is indicating that we are getting a declining rainfall,"

In 2018 Lord Howe Island endured its driest year in 132 years, receiving about 500mm less rainfall than the average.

Mt Anne / Eliza Plateau certainly had a close call, *&%$#! fire creeping up the ridge lines.

Does anybody know how High Camp hut fared?

Apparently it didn't get burnt - but the track won't open for 'an extended period'. (see Parks website)
They also have updates on specific areas - last one on 10/2, but some earlier updates are still relevant.

There were rumours that HCH had been burnt but parks released an update the other day saying it was unaffected: https://www.parks.tas.gov.au/?base=50500

Edit: Tortoise beat me to it :)

"The majority of the burned area is comprised of flammable vegetation communities. Fires in the west of the state (Gell River, Southwest, West Coast) have burned large tracts of sedgeland and buttongrass moorland (45-75% of burned area; Figure 2), whilst the Riveaux-Pedder fire complex is dominated by wet eucalypt communities (50% of burned area). The Central Plateau fire consists largely of dry eucalypt forest (65% of burned area). These vegetation communities have an ecology based on frequent (e.g. moorland and scrub) or infrequent fires (e.g. wet eucalypt) and consist of plant species with a range of adaptions to fire. We expect these vegetation communities should successfully recover over time."

As they have done in the past. With climate change however, the more frequent and intense fires will result in changes to the distribution or even the extinction of communities in heavily impacted areas. It is probable that areas such as Mt Bobs will remain as refuges for the communities observed there... but we are really heading into unchartered territory.

More frequent - and more intense - fires in the sedge/heath communities means an eventual loss of the peat soils that support them, as the peat itself is flammable. One particular fire on the west coast only stopped because it reached an area that had been burnt to bedrock fairly recently.
As that excerpt says "...recover over time". That means long enough without another fire of similar (or greater) intensity. And with our changing climate, the likelihood of that is remote.

Yes. The peat and soils will also be exposed to erosion from rainfall for the period following fire until the vegetation recovers. Prescribed burns have the same impact as they target ground cover.

Excellent. I'll take snow to put out the fires. :)

Has anyone got an update on access to Western Arthurs, or the best places to keep an eye on for info - have a trip to Oberon and back planned there for the end of March.

- have been keeping an eye on MAPS/ Tas Fire/TasAlert/Sentinel Hotspot for areas that have burnt/remain burning???
- have also seen the Parks closures/reopenings etc

Just after any intel of people who may be in the know...cheers

Scott’s Peak Road is still Authorised Access only so until that is lifted you won’t get to many SW walks
