Streamside Reforestation: An Analysis of Ecological Benefits and Societal Perceptions

[9613588]斯威尼河畔重新造林：生态效益和社会观念分析。建议将河边森林作为一种土地利用方法，通过清除营养物、沉积物和有毒污染物的输入来保护水生生态系统。该项目将河边森林视为河流宽度的主要调节者：小的森林河流比草甸河流更宽。森林砍伐导致的河流宽度的改变，通过对栖息地和水质的影响，深刻地影响了当地和下游的河流生态系统。恢复河边森林的政策既需要记录生态效益，也需要了解影响其实施的社会因素。目标是：(1)了解森林缓冲带、宽度和河流生态系统状况之间的关系；发展有助于指导森林恢复政策的数据库；(3)量化影响河滨森林恢复的社会经济问题。最终目标是让决策者关注自然科学和社会科学的组成部分。

9613588 Sweeney Streamside Reforestation: An analysis of ecological benefits and societal perceptions. Streamside forests are recommended as a land use practice to protect aquatic ecosystems by removing inputs of nutrients, sediments, and toxic contaminants. This project views streamside forests as the primary regulator of stream width: small forested streams are wider than meadow reaches. The alteration of stream width that results from deforestation profoundly influences the stream ecosystem, both locally and downstream through effects on habitat and water quality. Policies to restore streamside forests will require both documentation of ecological benefits and an understanding of societal factors affecting their implementation. Objectives are to: (I) understand the relationship between forest buffers, width, and stream ecosystem condition; (ii) develop data bases that can help guide forest restoration policies; and (iii) quantify social and economic issues affecting streamside forest restoration. The ultimate goal is to bring natural and social science components into focus for decision makers.
