自然资源

  • 对自然资源的承诺: 加州高铁管理局将保护加州独特的自然系统和景观放在首位,我们的目标是建设对环境影响最小的高铁系统。
  • 动物友好型基础设施: 该项目将野生动物走廊纳入其结构设计中,通过让动物安全地穿过铁轨来保护生物多样性。除了允许野生动物穿过轨道下方和轨道上方的桥梁、立交桥和高架桥外,我们还建造了 250 多条野生动物通道。我们还加入了一些设计元素,以帮助大型鸟类安全地栖息。
  • 栖息地保护: 为保护和恢复受高铁建设影响的自然栖息地,当局正在实施大规模项目。管理局已恢复了 4,400 多英亩退化土地,其中包括 151 英亩湿地。
  • 农业保护: 我们保护了 3,190 英亩的农业用地。根据 2023 年的估计,1,654 英亩的土地将面临开发风险。自 2019 年以来,因农业地役权开发权失效而避免的累计排放量为 348,700 MTCO2e。
  • 水利: 管理局在施工和运营期间实施节水措施。2023 年,管理局的施工用水量仅增加了 20% 多一点,而同期的施工活动却增加了 26% 以上。所用水中有 90% 是非饮用水。

保护脆弱的野生动物栖息地

A graphic image of a high-speed rail train crossing a viaduct structure in a natural habitat. The image outlines how dedicated crossings have been constructed underneath structures to allow native California species like the San Joaquin antelope squirrel, Tipton kangaroo rat, San Joaquin kit fox, and Buena Vista ornate shrew to cross the high-speed rail alignment. It also features a description of how overpass bridges and grade separations will not only connect roads and streets, they will also serve as larger wildlife undercrossings. The image shows how viaducts will carry high-speed trains over creeks and rivers, allowing for uninterrupted hydrologic connections and aquatic and riparian habitat for vulnerable and endangered aquatic species such as the vernal pool fairy shrimp, vernal pool tadpole shrimp, and California tiger salamander. The image also features four descriptions of species. The San Joaquin kit fox is on the federally endangered and state threatened species lists. They live in arid valley and foothill grasslands, sparsely vegetated scrub habitats, and some agricultural and urban areas. The inch-long vernal pool fairy shrimp lives only in seasonal pools that form when winter rains fill shallow depressions. It was federally listed as threatened in September 1994. The Tipton kangaroo rat, one of three subspecies of the San Joaquin kangaroo rat, was listed as a federally endangered species in July 1998. The California tiger salamander is a large terrestrial salamander with a distinct population in Central California. It is on the federal and state threatened species list.
