在加州, 私人及私营公司拥有的生产性林地占45 % 。为了收获木材, 这些林地的业主需要持有执照的专业林业工作者准备一份详细的经营计划, 该计划需经州政府广泛的审阅。这种经营计划往往耗资6 000 ～12 000 美元或更多的资金。计划的准备及州政府的审阅耗时6 个月或更长的时间。林业工作者所作的决策受到法律、林地条件、经济状况和林地业主的目的等限制。林业实践法规对造林体系的选择及采伐后要达到的更新量有详细的标准。项目可行性中要考虑的因子包括准备计划的成本费用、树木的标号、砍伐、管理、运输、税务、造林及任何受保护物种的存在。许多面积小于16 hm2 的林地, 其成本费用会超过立木所产生的收益。对加州林地业主来说, 重要的是日趋严峻的受规章制度限制的大气候、高额的遗产税及极度的火灾隐患。由于大众对森林及林产品的美学要求, 加州正面临着大量进口木制品。在现有的法律框架内, 林业工作者要平衡生态学、经济学及加州居民的意见, 以便为他们提供各种价值的物品。表2 参2
In California, private and private companies own 45% of productive woodland. To harvest timber, the owners of these woodlands need a licensed professional forestry worker to prepare a detailed business plan that is subject to extensive government review. Such business plans often cost between 6,000 and 12,000 U.S. dollars or more. Plan preparation and state government reviews take six months or longer. Decision-making by foresters is limited by law, woodland conditions, economic conditions and the purpose of forest owners. Forestry practice laws and regulations on the selection of afforestation systems and logging to achieve the updated amount of detailed standards. Factors to be considered in project feasibility include the cost of preparing plans, the labeling of trees, felling, management, transportation, taxation, afforestation and the existence of any protected species. Many woodlands with an area of less than 16 hm2 will cost more than the revenue from standing wood. What matters to the California forestland owners is the increasingly severe regulatory climate, high estate tax and extreme fire hazards. Due to the public’s aesthetic demands on forests and forest products, California is facing massive imports of wood products. Within the existing legal framework, foresters need to balance ecology, economics and the opinions of California residents in order to provide them with items of value. Table 2 reference 2
