Cathedral Fig Walk with Redcliffe Tree Society

Cathedral Fig Walk

Redcliffe’s Cathedral Fig Walk

Today I joined the recently formed Redcliffe Tree Society beside Moreton Bay. We met at Prince Edward Parade to admire the ‘Cathedral Fig Walk’ of native fig trees (Ficus benjamina) planted over half a century ago by (now former) Redcliffe council.

The effect of the planting has been to create a green roof, a double avenue of evergreen fig trees. This created a lush, leafy street. Tree canopies have become interlinked into one massive, green mosaic.

As a consequence, these trees have made this location a more desirable place to live, and a more habitable place for a home. Residents won’t have to worry as much about air-conditioning bills as people living in hotter, less well ‘treed’ streets. Thanks to these living air conditioners, it’s up to 7C cooler in their shade. When times are sticky, bring your deckchair, and chill. Maybe one day there will be benches for visitors.

When first I heard about this double avenue of Ficus benjamina, I pictured massive trees. Instead they are quite compact. This, I believe, is for two reasons. The street, the paving and generally tough growing conditions have somewhat tamed these forest trees. Second, they were once regularly lopped and this further limited branch and root growth.

If I had chosen a species of fig to plant as a double avenue, I would have gone for White fig, Ficus virens. This native is semi-deciduous. When I worked at Sydney Botanic Gardens we chose this species to replace the declining evergreen Moreton Bay fig trees (Ficus macrophylla) that lined Hospital Road in the Sydney Domain.

When White figs shed their leaves in spring, they also ditch the debilitating, sap-sucking pests, especially psyllids, living on them. Psyllids plagued the Moreton Bay figs along Hospital Road, hastening their demise.

Should Moreton Bay Regional Council adopt a long term conservation plan for this fig avenue, I would suggest filling gaps with White fig – a successional species.

What else makes this avenue a valuable community asset? Coastal tree plantings shelter adjacent properties from gales sweeping across Moreton Bay.

As with all plants, leaves soak up atmospheric CO2 and, through photosynthesis, create their own energy and store carbon in their tissue as they grow. Atmospheric carbon becomes terrestrial wood.

Many studies have shown that plant foliage mitigates traffic pollution (city air) and that tree canopies capture lots of rain, reducing stormwater flows.

Plant roots also capture nutrients and silt, improving stormwater quality. In this slice of Redcliffe less pollution is entering the seagrass meadows of Moreton Bay Marine Park, a site of special scientific interest for birds and dugongs.

Probably the most vital study taken to evaluate to economic and environmental benefits of urban forests was ‘The Benefits of Trees’ undertaken by the City of Boulder, Colorado (USA). That region is less than a quarter of the size and population of the Moreton Bay Regional Council.

“Trees live and provide benefits well beyond one human lifespan…all of the above plus habitat, traffic calming, human health benefits, wind dissipation, connection to landscape history and all of the personal connections and stories that are attached to each tree”.

I’d love to see this avenue of trees with a sign explaining the cultural significance of these veteran trees to residents and tourists.

How fortunate that these trees are not quite middle aged. There’s even space to extend this avenue into adjacent Grant Park, and if the bee-killing, weedy, suckering, seeding African Tulip tree (Spathodea campanulata) were grubbed out, there would be even more plantable spaces.

With regular health checks, and a little TLC, Prince Edward Parade’s ‘Cathedral Fig Walk’ could well cool and shelter the next generation.

My best wishes to Moreton Bay Regional Council.

“I grew up here, with this walk 80m from my home. I would walk, ride my bmx and skip through the figs all the time. I hope the council keep them and work out way that benefits everyone, they are amazing trees!”

Kirsty Fields
“I only recently moved off Prince Edward Pde after living there for 12 years with my daughter. We did & still do love walking the fabulous fig stretch you’ve just visited Jerry. It has several side streets that also have some great examples of treelined blocks/ avenues I hope you got to check out too.

The regular lopping to avoid issues with power lines have definitely assisted with their size. And their roots overall have not been too invasive considering the size and destruction they could have caused. As Jerry has said in this circumstance the pavement & bitumen have luckily for council curtailed potential problems”.

“Agree wholeheartedly Annemarie Butler! What an inspiring interview”.

Simon Paul Brown
“I constantly see ‘abominations’ to our street trees ect. Makes me very sad and frustrated. These look magnificent!”

“This month’s bus trip with my garden club taking place next week, is a guided tour of Redcliffe’s park & garden highlights. I hope it includes this leafy parade of trees!”
