However, our emissions profile is not guaranteed into the future. Emissions are influenced by factors such as population growth, major bushfire events, changes in consumer demand, market forces and technological advancements. Tasmania contributes significant and growing greenhouse gas emissions and we still have a heavy reliance on fossil fuels.

PERFECT WEATHER FOR CRAYFISH FIELD DAY

It was a great day out weather wise and information wise for the thirty or so landholders and community members who attended the Giant Freshwater Crayfish Field Day on the Duck River on 5 April

Participants had the chance to see project works undertaken by the landholder including weed and willow control, fencing on both sides of the river, offstream water points installed and the impact that stock exclusion has had on the siltation along the bed of the river in this location

Crayfish expert Todd Walsh also showed off live specimens of both juvenile and adult crayfish and spoke about their life cycle and habitat requirements

Associate Professor Matthew Harrison from UTAS spoke about the productivity benefits of managing soil carbon and the challenges to look out for when deciding on whether to participate in soil carbon markets

Photo: Dr Helen Morgan from the Tasmanian Land Conservancy provided some really practical advice on what does and doesn’t work well in designing and implementing revegetation projects, particularly along river corridors This was based on her own knowledge, but also site inspections on at least four of the properties across our region who undertook riparian revegetation as part of the Giant Freshwater Crayfish Project

LINK, LEARN AND LUNCH

The ‘Link, Learn and Lunch’ on 24 May was a lovely event, bringing together community volunteers from across the Cradle Coast region who are caring for our natural resources. We had almost 80 people at the event representing 38 different volunteer groups engaged in a huge variety of activities from native wildlife monitoring to feral animal control, building soil biology through to building community, plus mountain bikers, kayakers and bushwalkers protecting special places. The feedback was consistent:

everyone loved connecting with other like-minded people and hearing about the great diversity of activities volunteer groups are tackling and the results they are getting!

We started the day meeting Brendan and Brenton, pakana rangers from the Tasmanian Aboriginal Centre, who spoke about how they care for country and community This was an opportunity to think about how the areas we manage were shaped by Tasmanian Aboriginal people over tens of thousands of years Their land and cultural practices were violently invaded as lutruwita/Tasmania was colonised Brendan and Brenton are continuing palawa/pakana culture and land management for the benefits of community and the environment and attendees valued connecting with and learning from them

SPECIAL SUBSPECIES OF KING ISLAND

King Island, once connected to both Tasmania and the Australian mainland by the Bass Strait land bridge, was isolated over 10,000 years ago as the last ice-age ended, and Bass Strait flooded. Consequently, many species on King Island are endemic. King Island’s fascinating but fragile bird population is no exception.

The island hosts not only a swathe of migratory birds, and is an invaluable stepping stone for many, but is home to resident subspecies of global importance. A number of these birds are threatened including the King Island Scrubtit (Critically Endangered), King Island Brown Thornbill (Critically Endangered), the King Island Green Rosella (Vulnerable) and the King Island Black Currawong (Vulnerable) according to the Environment Protection and Biodiversity Conservation Act List.

Themaincontributorstothesebirds’plightsare habitatlossthroughlandclearingandfirerisk. Agriculturaldrainingandherbivoregrazingarealso knowncausesofhabitatdegradation

OnevictimofthesethreatstohabitatonKingIslandis theYellowWattlebird KnownasAustralia’slargest honeyeater,andendemictoTasmania,thisbirdhasa subspeciesdistincttoKingIsland–theKingIsland YellowWattlebird(Anthochaeraparadoxakingi).

p. 12

The KI Yellow Wattlebird can be distinguished from its Tasmanian cousin by its smaller size Known for its rather unfortunate squawk (which is no-doubt charming to other wattlebirds), the Yellow Wattlebird sports a yellow belly and has a pendulous yellow wattle or skin flap that hangs on either side of the neck

The rare bird can be described as active, noisy, and conspicuous – if you can’t see it, you’ll probably hear it!

The 2020 Action Plan for Australian Birds identified the KI Yellow Wattlebird as “endangered” but it has not been formally listed yet.

Focused research on all of King Island’s special subspecies is needed to accelerate conservation activities.

Later this year, NRET will introduce Recycle Rewards - a Container Refund Scheme (CRS) which incentivises people to return eligible used beverage containers to a Refund Point inreturnfora10crefund.

In 2021, the City of Hobart enacted a law to ban single use plastic takeaway food packaging and related items. The rest of the state has committed to phase-out problematic singleuse plastics (PSUPs) such as plastic straws, bowls, plates, utensilsandexpandedpolystyreneconsumerfoodcontainers by2025.

Landcare Group is on the lookout for sightings of this new beach invader! It is Beach Daisy. Common on the mainland and present on Flinders, it has now been recorded at two sites on King Island. If you see it there, report it to KI Landcare Group. On 03 6462 1825, and if it’s elsewhere on the Cradle Coast let Cradle Coast NRM or Biosecurity Tasmania know.

Management of the reserve focuses on removal of shrubby weeds such as Blackberry (Rubus sp) and Bluebell Creeper (Billardiera heterophylla) Reid Street Reserve has no documented history of clearing, in fact tree cover today is greater than it was 70 years ago Hence it is home to mature Eucalyptus amygdalina and E viminalis Forest (Black Peppermint Coastal Forest) with a shrubby and sedgy understory The forest does not appear to have been frequently or intensely burned in recent decades, and “bug hotels” (rotting logs, leaf and bark accumulations) are widespread which is all good news for biodiversity and reflects the importance of small reserves as habitat, even within urban areas

Central Coast Council has recently released their draft Natural Resource Management Plan, which includes an assessment of the natural values of Reid Street and other council-managed reserves With the combined attentions of the Friends of Reid Street Reserve and the Council’s NRM staff, it seems the important biodiversity of Reid Street is in safe hands

What is a Marine Protected Area?

The World Conservation Union (IUCN) Guidelines identify four key things that separate a proper marine protected areas from other managed marine areas. These characteristics are that:

The MPA has been established especially for the conservation of biodiversity; It is able to be classified into one or more of the six IUCN Protected Area Management Categories meeting the values and objectives of the proposed MPA; It must have secure status which can only be revoked by a parliamentary process; and It contributes to the representativeness, comprehensiveness or adequacy of the national MPA system
