[1] The remnant pecan nut grove in the former Queensland Acclimatisation Society Gardens at Lawnton, a residential suburb north of Brisbane in the then Shire of Pine (later rename Shire of Pine Rivers, Moreton Bay Region and City of Moreton Bay), contain a number of mature trees which are all that remain of a dense grove planted by the society between 1915 and World War II.
[1] Acclimatisation in the nineteenth century was scientifically understood to mean the process by which animals and plants gradually adapt to climatic and environmental conditions different to those that prevailed in their original habitats.
In Australia, however, scientific theory was not a primary motivation and acclimatisation came to represent simply the exchange of plants and animals with other countries.
It imported plants that had commercial potential and conducted experiments to determine if they could be adapted to Queensland's tropical and sub-tropical climate.
In that year, the Queensland Acclimatisation Society began importing cane from Mauritius and New Caledonia and distributing it to growers.
[1] Between 1914 and 1915, the society closed its first gardens at Bowen Park and moved its operational base to a 100-acre property on the south bank of the North Pine River at Lawnton.
In March 1915, tenders were requested for the construction of a new cottage (extant but altered) including a "roomy office" for storing the society's books and papers.
The society contributed to making avocados, pecan nuts and grape fruit commercially viable crops in Queensland.
It is difficult to establish a direct link between the Acclimatisation society's work on pecan nuts and the present commercial crop.
However, the pecan nut trees at Lawnton are the only pre-World War II Acclimatisation Society plantings, known to be extant, that are related to commercial crops.
[1] Remnants of former acclimatisation society gardens at Lawnton were listed on the Queensland Heritage Register on 8 May 2009 having satisfied the following criteria.
Pecan nuts are now a commercial crop in Queensland and the trees at Lawnton constitute the only known plantings related to the society's pre-World War II work in economic botany.
