Abstract
. Across its entire range in Australia’s western and southern rangelands, Australian sandalwood ( Santalum spicatum [R.Br.] A.DC.) is on a path towards ‘extinction in the wild’––the International Union for the Conservation of Nature’s penultimate category of conservation risk. Sandalwood populations have substantially diminished or become locally extinct, predominantly a consequence of land clearing for agriculture, introduced grazers, disruption of key ecological processes (e.g. seed dispersal, fire regimes) and 175 years of intensive commercial exploitation for its fragrant, high value timber. The status of the world’s last wild-harvested species of sandalwood is significant to both conservation and rangeland management, and the implementation of a science-based sustainable yield approach to management of this species is vital. By highlighting the scale and precipitous rate of decline and identifying key drivers affecting mortality and recruitment, this review outlines the conservation and restoration needs of the species in situ to conserve remaining wild populations, and the need to transition to science-based resource management actions such as farm-based plantation production.
. 在澳大利亚西部和南部牧场的整个范围内,澳大利亚檀香(Santalum spicatum) [R.Br.])正在走向“野外灭绝”——这是国际自然保护联盟(International Union for Conservation of Nature)的倒数第二种保护风险。檀香种群数量大幅减少或在当地灭绝,这主要是由于农业用地清理、引入食草动物、关键生态过程(如种子传播、防火制度)的破坏以及175年来对其芳香、高价值木材的密集商业开发造成的。世界上最后一种野生檀香的现状对保护和牧场管理都具有重要意义,实施以科学为基础的可持续产量方法来管理这一物种至关重要。通过强调下降的规模和陡峭的速度,并确定影响死亡和补充的关键驱动因素,本综述概述了原地物种保护和恢复的需求,以保护剩余的野生种群,以及过渡到以科学为基础的资源管理行动的必要性,例如以农场为基础的种植生产。
期刊介绍:
The Rangeland Journal publishes original work that makes a significant contribution to understanding the biophysical, social, cultural, economic, and policy influences affecting rangeland use and management throughout the world. Rangelands are defined broadly and include all those environments where natural ecological processes predominate, and where values and benefits are based primarily on natural resources.
Articles may present the results of original research, contributions to theory or new conclusions reached from the review of a topic. Their structure need not conform to that of standard scientific articles but writing style must be clear and concise. All material presented must be well documented, critically analysed and objectively presented. All papers are peer-reviewed.
The Rangeland Journal is published on behalf of the Australian Rangeland Society.
