At Otto Timber we are not only passionate about timber, but we are also passionate about sustainability, taking care of our environment and ensuring the future of our industry. Since we benefit from our environment through the beautiful timbers we get, we like to give back to our environment through supporting causes like Fifteen Trees.

A variety of native plants are critical to creating biodiversity.



Hindmarsh, SA |  2023 | 200 trees

Thanks to Nathan and his team, Friends of Hindmarsh River Estuary planted a mixture of species indigenous to the district, and grown from locally collected seeds. Species included; Golden wattle, Seaberry saltbush, Banksia, Kangaroo thorn, Drooping sheoak, Manna Gums and Swamp Paperbacks. The native trees and shrubs were planted at several locations along the Hindmarsh River Estuary.

The planting will provide protective nesting vegetation for the threatened Hooded Plover and species such as Crested Shrike Tit, Black-chinned Honeyeater and Yellow Tailed Black Cockatoos.


More friends.



Many thanks. Your support is invaluable in assisting our group to improve the ecological environment of a the much-loved Hindmarsh River in SA.

We now have a series of signs along the estuary, inviting the public to download the Birdlife Australia Birdata app and participate in surveys.

Slatey Creek, VIC |  2023 | 194 trees


Otto Timber trees were planted at Slaty Creek, VIC. The trees were a mix of purposefully selected plants to complement the birdlife, insects, and other creatures who call The Grampians their home. They were selected to survive both the cold winters and dry summers, the mountainous terrain experiences. The trees will grow to varying heights (tall and understory) to ensure a variety of habitats for the local wildlife (including some of the bird species shown below).



We are thankful for the expertise of the Buloke and Northern Grampians Landcare Network in their support in helping to plant these trees. Here’s an interview, we recently conducted with Andrew Borg, coordinator of this network.

The trees will add to the amazingly diverse landscape consisting of gorge environs, steep rocky walls famous for rock-climbing, deep valleys, and undulating hills. They will provide homes and fodder for many species including the extensive bird life found there. Given it is a famous area for bushwalking, you’ll often find many avid bird watchers (twitchers) hiding out on the trails, binoculars in hand and taking in the immense bird song. Grampians birdlife is vast and the many winged wonders you may come across include parrots (Galah, Crimson Rosella, Musk Lorikeet, Rainbow Lorikeet and Blue-winged Parrot), and cockatoos (Sulphur-crested Cockatoo, Gang-gang Cockatoo, Long-Billed Corella, Little Corella, Yellow-Tailed Black-Cockatoo, even the endangered Red-Tailed Black Cockatoo).


Planting took place along eroded creeks and gullies to stabilise and protect the soil.


We are only too pleased to work with organisations like Otto Timber when they feel as passionate about our planet as we do.

Tasman Cottage already gives you a chance to reconnect with nature, yet its manager Nick has taken an important next step. He recently purchased 150 trees in collaboration with us here at Fifteen Trees, an action which ensures vital habitat for our native fauna, such as the unique Tassie Devil.
