Interactive Suitable Tree Species Selection and Management Tool for East Africa- Ethiopia

This dataset was moved to: https://doi.org/10.34725/DVN/ZTT9EF1. The tool aims at promoting tree diversity on farm and in landscapes, including useful exotic tree species that the existing vegetation maps do not capture. The tool currently consists of 209 (147 native and 62 exotic) tree species in Ethiopia, disaggregated according to agro-ecological zone suitability. The database enables the user to easily access information either based on tree species, their agro-ecological zone suitability, products, environmental services, origin (native or exotic) and niche. The tool also provides specific details on the trees’ biophysical growth conditions and management requirements as well as links to other agroforestry databases. 2. The tool contains rich information from knowledge-intensive and detailed tree diversity studies: The tool is a composite of different studies and surveys done by working with different stakeholders such as researchers, farmers, extension workers and local partner organizations. These include: o Tree diversity studies- shows the current tree diversity trends o Local knowledge studies- captures tree species according to niche locations, most important tree and preferred tree niches. Historical timelines captures tree species that have been lost or are close to extinction, as well as reasons for these trends. o Baseline studies- captures patterns of tree adoption on farms o Seed and Seedling System surveys- captures what tree species farmers are planting currently, including the most popular tree species, which implies future trends o Land Degradation Surveillance Framework: presents biophysical assessment of tree distribution, including tree density o Literature review- such as the Useful trees and shrubs for Ethiopia- was used to provide additional information such as: biophysical growth conditions, management practices etc and in addition to triangulate information already captured through the other approaches 3. Tracking tree species’ trends: The tools provide an insight into the past, present and future tree species trends on landscapes. Source of information for each tree species, which is guided by the studies named in 2 above is provided (by an asterisk). Double asterisk signifies trees that are deemed most important by farmers in a given area. 4. Scalability: Information provided in the tool can be easily used to select suitable tree species for scaling up and scaling out agroforestry interventions to similar agro-ecologies. 5. Further it is possible to update information on the tool as more tree species are encountered. Science with grass-root impacts: The tool is interactive and targets a wider audience for promoting ‘Research in Development’ agenda: The tool is easy to use and targets not only researchers but also local extension workers, who are key in scaling up and out agroforestry in interventions. It provides local names of tree species that can easily guide the users at the local level to identify the tree species. We hope to explore ways of packaging the information in forms that can be readily available to local partners like CDs etc.

本数据集已迁移至：https://doi.org/10.34725/DVN/ZTT9EF1。本工具旨在推动农田与景观中的树木多样性保护与发展，涵盖现有植被图谱未收录的有用外来树种。目前，该工具收录埃塞俄比亚境内209个树种（其中本土树种147种、外来树种62种），并按农业生态区（agro-ecological zone）适宜性进行分类。该数据库支持用户基于树种、其农业生态区适宜性、产品、环境服务、起源（本土或外来）及生态位（niche）快速获取相关信息。此外，工具还提供了树木生物物理生长条件、管理要求的详细细节，以及与其他农林业（agroforestry）数据库的关联链接。
2. 丰富的知识密集型精细树木多样性研究信息：本工具整合了与多方利益相关者（stakeholders）合作开展的多项研究与调查成果，合作对象包括研究人员、农户、农业推广人员（extension workers）及本地合作组织，具体涵盖：
- 树木多样性研究：揭示当前区域树木多样性的变化趋势
- 本土知识研究：依据生态位区位收录树种，明确核心树种与偏好树种的生态位；历史时间线记录了已消失或濒临灭绝的树种及其成因
- 基线研究（baseline studies）：记录农户在农田种植树木的采用模式
- 种苗系统调查：收录农户当前种植的树种，包括最受欢迎的热门树种，可反映未来种植趋势
- 土地退化监测框架（Land Degradation Surveillance Framework）：呈现树木分布的生物物理评估结果，包括树木密度
- 文献综述：例如《埃塞俄比亚有用树木与灌木》，用于补充生物物理生长条件、管理措施等相关信息，并对其他渠道获取的信息进行交叉验证。
3. 追踪树种动态：本工具可展现景观中树种的过去、当前与未来发展趋势。每个树种的信息来源均已标注（以单个星号表示），具体对应前文第2部分提及的各类研究。双星号则代表某一区域内农户认定的最重要树种。
4. 可扩展性：工具中收录的信息可轻松用于筛选适宜树种，以在相似农业生态区推广农林业干预措施，实现规模化应用与范围拓展。
5. 支持动态更新：当发现更多树种时，可对工具中的信息进行更新。
兼具基层实践价值的科学工具：本工具具备交互性，旨在推广“研究促进发展”（Research in Development）议程，服务广泛受众。工具操作简便，不仅面向研究人员，还针对在农林业干预推广中发挥关键作用的本地农业推广人员。工具提供了树种的本地名称，可帮助基层用户快速识别目标树种。我们计划探索将该信息以光盘等形式打包，以便本地合作方便捷获取。
