"Bring the Butterflies Back to Adelaide" Campaign

 

I am delighted to today launch Bring the Butterflies Back to Adelaide Campaign organised by Butterfly Conservation SA.

  Butterfly Conservation SA was formed to raise the awareness of Butterfly Conservation in

 South Australia, in large part to answer the question:

 “Where have all the butterflies gone?”

South Australia plays host to more than 75 species of butterfly, some sedentary, others capable of extensive overland migrations. The Adelaide Metropolitan area itself ‑at less than 0.2% of the States land mass, plays host to more than 2 dozen species of butterflies, including blues, hairstreaks, browns, whites, darts, monarchs, orchard butterflies and more.

  Therefore the City of Adelaide, with a third of the States species is a butterfly "hot spot" and if we wish to conserve butterfly biodiversity, one of the places to do so, is right here in our own back yards.

Not only does our region here have very significant butterfly biodiversity, it also has spectacular abundance. Some of our resident species, like the common brown, are here in large numbers. We are also lucky enough to experience wonderful migrations of Caper Whites, Painted ladies and monarchs as they sweep across our city in their hundreds of thousands.

However, butterflies are under threat. Many species have gone from some regions of the City. The abundance and diversity of our native butterfly species has been decimated through urbanisation, the clearing of grasslands, draining of swamps, fire and the indiscriminate removal of perceived weeds such as endemic parasitic plants like mistletoe and real weeds like thistle and cottonbush which are food for the caterpillars of our most loved butterflies.

  In particular the disappearance of the back yard has had a profound effect on butterfly numbers. We choose to house our growing population in larger houses on smaller blocks.

  We undertake Urban infill programs where houses appear where backyards and tennis courts used to be. We are also creating housing estates where there are no street scapes, and front and back space is minute.

The argument for this style of building is ; People don't want back yards ‑they are too busy, too tired or too disinterested to maintain a garden.

Perhaps even worse, the "backyard" trend in these new houses now is towards cement and tile based "NeoTuscan" gardens with only a few ornamental plants and little biodiversity ‑Certainly no where for the butterflies to feed.

The disappearing back yard has enormous effects on butterflies: Should we care?

Yes!

 Butterflies are one of the most recognised and loved insect. They feature in stories from

different cultures around the world and inspire artists and designers to create colourful displays

of craft and motifs. They also reflect the beauty and fragility of nature. People like having

butterflies in their gardens and reserves, even though they forget that to have butterflies in your

garden you need the caterpillar stage, and these are one of the least liked insects!

We now run a very real risk of this generation of Adelaideans growing up without experiencing a butterfly. It is hard to imagine a childhood without butterflies, but that is now a real possibility for many of our children. This is both sad for its own sake but also of great concern because it means the next generations will grow up disconnected from the natural environment. Without experiencing natural wonders such as butterflies, how can we expect them to become involved with, and deal with the enormous environmental problems we face world wide.

So how do we bring them back?

Gardening is a favourite activity of many Australians. With the introduction of water restrictions, many gardeners are re‑thinking the design and make‑up of their garden to ensure their garden's survival through long periods of little water. As we rethink the structure and nature of our gardens it is timely to also design them for our most loved animal ‑the butterfly.

 Butterflies need plants to survive. Adult butterflies suck nectar from suitable nectar plants.

The caterpillars eat the leaves of very specific food plants.

Whilst several species will feed on our vegetable patch the vast majority of caterpillars feed on a variety of indigenous plants including grasses, sedges, pea flowering bushes and some trees including wattles or feed on introduced weeds like nettles or cottonbush.

By planting butterfly and caterpillar food plants or by ensuring these plants survive in reserves and parks, we can encourage butterflies to visit and breed in our gardens and reserves.

If we can create butterfly habitat in our gardens, and conserve existing habitat in reserves, then we will also create the conditions that also ensure the survival of other invertebrates. This in turn will ensure the survival of larger animals‑the birds and lizards that prey upon these insects.

The new Butterfly Gardening website launched today will provide an opportunity for us all to find out which plants local butterflies feed upon and which indigenous butterfly­friendly plants can be grown in each area of the Adelaide plains. A future plan is for the website to be expanded to all of South Australia.

Once people have made a commitment to conserving butterflies by creating a butterfly friendly garden or are making a special effort to conserve existing butterfly habitat in remnant scrub they may register registering heir garden, park or patch of scrub as a 'Butterfly Site'. They will then be able to purchase a  Butterfly Site sign to promote their commitment to the community and use the Butterfly   Gardening logo. Registration forms and information on butterfly gardening will be found  on the new website.

By way of example, this beautiful butterfly garden has been created with assistance from the SA Urban Forests Million Trees Program and members of the Urban Forest Biodiversity Program team. Creation of the website would not have happened with out the financial support from the Norman Whettenhall Foundation and for this the members of Butterfly Conservation SA are very grateful.

 The "Bring back the Butterflies" Campaign will hold a number of significant events over                      the coming year:

There will be an exhibition at the SA Museum due to be launched on 21 September entitled:

 "Bringing the Butterflies Back" and a book on book on Butterfly Gardening will be launched  soon. This will be a great reference for Adelaide gardeners wishing to set up a butterfly   garden.

I would like to acknowledge the huge amount of effort put into this campaign by Jan Forrest, Matthew Barbour and their committee and am proud to launch the website, garden and program. This program will ensure that the most commonly asked question is no longer:

 

“Where have all the Butterflies gone?”

But

                        “How can I help to bring them back?”
