The provision of ecosystem services from vegetation on private land is constrained by a lack of effective markets to overcome the costs of supply. Urban beneficiaries of ecosystem services from vegetation on private, rural land have limited options for enhancing the supply. This study examines a not-for-profit revegetation programme, the Tree Scheme, in which participants are volunteers who grow seedlings for revegetation on rural land, and rural landholders who use the seedlings in revegetation. We used records of participation and seedlings, along with participant questionnaires to investigate the flow of resources between volunteer growers and rural landholders. The programme produced approximately 22.5 million seedlings between 1994 and 2012; 79% of seedlings were grown in urban locations and 79% of seedlings were ordered for rural plantings. Landholders identified a mixture of objectives for revegetation, with improvement of habitat and biodiversity being most common, followed by objectives with higher private benefits, including planting for windbreaks, erosion control and screening. Volunteer growers reported liking the programme because of the programme's intended environmental benefits, the satisfaction they gained from raising seedlings and other social benefits of participation. The programme demonstrates that a substantial flow of resources between urban ecosystem services beneficiaries and rural producers can be achieved by facilitating voluntary actions. The type and scale of this programme is rare and potentially transferable.
植被的生态系统服务在私人土地上的供应受到缺乏有效市场的限制,无法克服供应成本。私人农村土地上植被的生态系统服务的城市受益者在增加供应方面选择有限。本研究考察了一个非营利性的重新造林计划,即 Tree Scheme,参与者是在农村土地上种植幼苗进行重新造林的志愿者,以及在重新造林中使用幼苗的农村土地所有者。我们使用参与和幼苗记录以及参与者问卷来调查志愿者种植者和农村土地所有者之间资源的流动情况。该计划在 1994 年至 2012 年间生产了约 2250 万株幼苗;79%的幼苗在城市地区种植,79%的幼苗是为农村种植而订购的。土地所有者确定了重新造林的目标组合,其中改善生境和生物多样性最为常见,其次是具有更高私人利益的目标,包括防风林、控制侵蚀和屏蔽的种植。志愿者种植者报告说喜欢该计划,因为该计划有预期的环境效益,他们从种植幼苗中获得的满足感以及参与的其他社会效益。该计划表明,可以通过促进自愿行动,在城市生态系统服务受益者和农村生产者之间实现大量资源的流动。这种类型和规模的计划很少见,具有潜在的可转移性。
