for sustainable special timber harvesting also was expressed from the Australian and Tasmanian Greens. In his letter to Br Bill Kelty, dated 6 March 2011, former Senators Bob Brown and Christine Milne called "for agreed areas to be set aside for sustainable selective logging of high-quality, specialty timbers." Later in 2011, former Senator Brown also stated in an article in The Examiner newspaper "The Greens have always wanted to provide for specialty timbers for craft work, furnishings, the things Tasmania are so famous for and proud of, in an ongoing forestry industry," he said "If the Libs find fault with that, crikey, is there anything they can agree too?" Research into post-harvest forest regeneration systems for rainforest commenced in north-western Tasmania in 1976 with fourteen rainforest harvesting and regeneration trials being established over the following decade. Subsequent monitoring of these sites has shown that dense regeneration of myrtle and other rainforest species occurs after harvesting on fertile sites if the seedbed is exposed and trees are retained for seed and shelter. One such trial established in the Tarkine was the Sumac forest harvest trials. Commenced in 1976, this trial was conducted to establish the best silviculture method for regenerating Myrtle dominated forest post harvesting to ensure an ongoing supply of special timbers. Harvesting techniques trialled included; selective harvesting, strip felling, shelterwood, clearfell with cull retention and clearfell. Regeneration techniques trialled included; ground scarification, post-harvest burning and for the selective harvest areas no treatment beyond natural canopy openings from felled trees and minor soil disturbance from harvesting equipment. The trial site was successfully regenerated and monitored over decades with the resultant research informing silvicultural prescriptions. In 2015, the World Heritage Committee Reactive Monitoring Mission toured the Sumac trial site with forest ecologists and stated what they had seen was "world's best practice". In 2017, aerial video footage was taken of the key trial site in the Sumac region which can be seen in this video. In 2014-17, a study into special timber location, standing volumes and perpetual sustainable yields was carried out. This project commenced under the Tasmanian Forest Agreement process with funding from the former federal Labor government and was completed in October 2017. Utilising best available modelling techniques including LiDAR, a standing volume of special timbers (14.3 million cubic metres) and subsequent annual sustainable yields in perpetuity were developed. Areas assessed included parts of the Tarkine where underlying land
