The Sierra Lakes Inventory Project: Non-Native fish and community composition of lakes and ponds in the Sierra Nevada, California

The Sierra Lakes Inventory Project (SLIP) was a research endeavor that ran from 1995-2002 and has supported research and management of Sierra Nevada aquatic ecosystems and their terrestrial interfaces. We described the physical characteristics of and surveyed aquatic communities for > 8,000 lentic water bodies in the southern Sierra Nevada, including lakes, ponds, marshes, and meadows. We also created digital map layers for these water bodies when such layers did not exist. The original objective of SLIP was to describe impacts of non-native fish on lake communities, but SLIP data has subsequently enabled study of additional ecological issues, including regional amphibian declines and their impacts on communities, and impacts of non-native fish on terrestrial species. In addition, these data are being used to develop fish removal efforts to restore aquatic ecosystems and recover endangered amphibians. The SLIP data is stored in a relational database that collectively describes water bodies (e.g., depth, elevation, location), surveys (conditions, effort), and communities (including approximately 170 fish, amphibian, reptile, benthic macroinvertebrate, and zooplankton taxa).塞拉湖清单项目（Sierra Lakes Inventory Project, SLIP）是一项实施于1995年至2002年的研究计划，为内华达山脉（Sierra Nevada）水生生态系统及其陆地交界带的研究与管理提供了长期支撑。研究团队对内华达山脉南部逾8000处静水水生态系统（lentic water bodies，包括湖泊、池塘、沼泽与草甸）的物理特征进行了系统描述，并对其水生群落开展了全面调查。在相关数字地图图层尚未存在的情况下，团队还为这些水体构建了专属的数字地图图层。该项目的初始研究目标为阐明外来鱼类对湖泊群落的影响，但后续SLIP数据集已支撑了多项其他生态议题的研究，包括区域两栖动物种群衰退及其对群落的影响、外来鱼类对陆地物种的影响等。此外，该数据集还被用于制定鱼类移除修复方案，以恢复水生生态系统并拯救濒危两栖动物种群。SLIP数据集存储于关系型数据库（relational database）中，该库完整收录了三类核心信息：水体相关参数（如深度、海拔、地理位置）、调查相关记录（如调查条件、投入强度）以及群落分类数据（涵盖约170个鱼类、两栖动物、爬行动物、底栖大型无脊椎动物（benthic macroinvertebrate）以及浮游动物类群）。
