<strong>Stirling</strong> Natural Environment Coastcare<br />
This brochure has been produced in association with <strong>Stirling</strong> Natural<br />
Environment Coastcare through funding from a ‘Caring For Our Country’<br />
community grant.<br />
<strong>Stirling</strong> Natural Environment Coastcare volunteers are dedicated <strong>to</strong> the<br />
environmental conservation and res<strong>to</strong>ration <strong>of</strong> the <strong>City</strong> <strong>of</strong> <strong>Stirling</strong> coastline.<br />
For many years they have worked tirelessly <strong>to</strong> remove invasive, non-native<br />
plant species and <strong>to</strong> res<strong>to</strong>re the coastal vegetation <strong>to</strong> a natural and resilient<br />
state.<br />
One <strong>of</strong> the most important challenges <strong>to</strong> coastal rehabilitation is preventing<br />
weed spread from domestic residences - coastal dunes are particularly<br />
vulnerable <strong>to</strong> this invasion. If you live close <strong>to</strong> the beach, you can assist in the<br />
valuable work <strong>of</strong> <strong>Stirling</strong> Natural Environment Coastcare by controlling and<br />
reducing weeds in your garden, and planting local natural coastal vegetation<br />
in its place. Doing this will s<strong>to</strong>p your garden accidentally contributing further<br />
environmental weeds <strong>to</strong> this threatened system.<br />
Weeds fail <strong>to</strong> properly support the animal communities (including birds,<br />
insects, reptiles and marsupials) that rely on the coastal diversity <strong>of</strong> natural<br />
plant species; and they eliminate the natural plants that these animals depend<br />
upon for food, nesting and shelter.<br />

The benefits <strong>of</strong> local native plants in your garden:<br />
• They are survivors that belong in the coastal<br />
environment – this means they are wind and salt<br />
<strong>to</strong>lerant, and therefore extremely resilient and adaptable;<br />
• They require very little or no regular watering;<br />
• They do not require soil improvers or fertilizer;<br />
• They are easy <strong>to</strong> maintain – no more expensive tree<br />
lopping and pruning around power lines;<br />
• They are visually attractive, with many different colours,<br />
shapes and sizes;<br />
Hardy, local plant species (recommended)<br />

Plants <strong>to</strong> avoid<br />
List <strong>of</strong> common garden escapee species - most prolific seeders and highly invasive.<br />
• They are generally low-lying, and<br />
therefore will not obstruct views;<br />
• Once established, they will naturally regenerate;<br />
• They are generally shallow rooted, therefore ideal for<br />
typical coastal gardens that have shallow <strong>to</strong>psoil over<br />
limes<strong>to</strong>ne;<br />
• Plant s<strong>to</strong>ck is grown locally, which supports the local<br />
plant nursery industry;<br />
• Will provide habitat for local native fauna.<br />

Key points on coastal gardens<br />
• It is important <strong>to</strong> remember that while the sizes <strong>of</strong><br />
these plants is a guide, height and spread will depend<br />
significantly on watering, maintenance and condition <strong>of</strong> the<br />
plant. Native species do not require a lot <strong>of</strong> water, so if they<br />
are exposed <strong>to</strong> excessive reticulation they will <strong>of</strong>ten grow<br />
bigger than average.<br />
• The ideal time <strong>to</strong> plant is around late April <strong>to</strong> May, after the<br />
first good autumn rains. Water as needed until winter rain<br />
sets in. This will give plants more time <strong>to</strong> establish before<br />
summer (See ‘Men <strong>of</strong> the Trees’ website for how <strong>to</strong> plant).<br />
• As the coastal environment is particularly exposed<br />
and subject <strong>to</strong> high levels <strong>of</strong> wind and salt, using plant<br />
protec<strong>to</strong>rs for new plants can assist initially in building up<br />
resilience until they are strong and hardy.<br />
• If you choose <strong>to</strong> mulch your garden, be sure <strong>to</strong> keep the<br />
mulch away from the plant stem – as this can cause ‘collar<br />
rot’ in some native species.<br />
• If you are interested in adding native coastal species <strong>to</strong> your<br />
garden, there is no need <strong>to</strong> remove all other existing plants.<br />
Some <strong>of</strong> these may have adapted well <strong>to</strong> the conditions and<br />
will compliment any changes in design.<br />
• If you have a lot <strong>of</strong> green waste <strong>to</strong> dispose <strong>of</strong>, contact the<br />
council for information on how best <strong>to</strong> do this. Dumping<br />
green waste in public areas <strong>of</strong> bushland is a serious<br />
problem and can lead <strong>to</strong> severe infestations <strong>of</strong> weeds.<br />
