Newsletter – Oct 2024

 

Greetings Friends,

This monthly newsletter (No. 45) includes a Senator’s visit, biodiversity and birds, Darwin development, FLP membership, quiz, plants and wildlife.

 

1.0 Darwin – City of Birds

Greens Senator Penny Allman-Payne found time for a Wilderness Walk at Lee Point on her recent visit to Darwin.

To date, we have had 5 Senators join us on the Wilderness Walk and are hoping to get more elected representatives on the walk soon.

 

Biodiversity and birds – The number of bird species present is a good indicator of biodiversity.

Visitors are often surprised and delighted by the large number of birds they see in tropical Darwin. A couple of reasons for this are:

  • over half the world’s vertebrate species (includes birds) live in tropical forests.
  • tropical savanna forests are a lot more open than tropical rainforests making it much easier to see birds.

In the last few years, approximately one quarter of the bird species recorded in Australia have been identified on the Lee Point peninsula (refer Fig 3.).

Visitors with binoculars get to identify many wild birds on a typical Wilderness Walk around Lee Point Dam. Up to 50 wild bird species have been identified and recorded on this 2-hour walk.

2.0 Darwin development

The main cause of biodiversity loss in urban areas is habitat loss and fragmentation, mammals and small birds are particularly impacted by both.

Having government (DHA) build houses away from jobs and frequent public transport, clearing critical habitat, does not address Australia’s:

  • Extinction crisis – Clearing critical habitat in Darwin threatens species that are already declining in number.
  • Climate change crisis – Darwin is getting hotter and it needs to keep its urban forests to cool surrounding areas and absorb greenhouse gases.
  • Housing affordability crisis – Darwin has a housing affordability problem, refer “unaffordable” housing at Lee Point

Planning for Lee Point has more information.

 

FLP are still seeking answers to these questions from the Australian Government; what other sites were considered to:

  • avoid an environmental offset, and
  • optimise long term public benefit.

Minister for Defence Personnel, Matt Keogh MP, is currently looking after DHA matters.

Take Action

The DHA Lee Point housing project is an ill-considered project for Darwin. It is time to save Lee Point – Please sign this PETITION.

4.0  Quiz

Q1         Why do termites fly after rain and in such large numbers?

5.0 Plants and Wildlife

With lots of sun and some rain, plant growth has taken off (as has lawn mowing) providing lots of food for plant-eating insects. Photos this month by Sam Duffy from Lee Point Biodiversity Corridor.

Wilderness Walks have been held every week at 5pm Sunday and sometimes in the morning at 7am – see FLP Facebook for latest info. Typically, the walks record 30-45 bird species, refer ebird for latest sightings. The 7am walk on Sunday 27 Oct 2024 recorded 50 species.

Fire damages habitat this time of year – If you see a fire on the Lee Point peninsula it is probably arson, call 000, response time is critical for controlling fires.

 

Hope to see you on a Wilderness Walk

 

Answers to Quiz

Answer – High humidity helps termites to survive and building a new mound is easier after rain. Termites are attracted to damp environments. Their thin exoskeletons mean they can lose moisture rapidly and in a dry environment quickly dehydrate and perish.
Flying in large numbers help reduce the loss from predators (they can only eat so much). Birds, lizards, and other animals feast on the termites because they are a good source of protein.
Very few termites survive to start a new colony, even under optimum conditions.
