从颈椎骨折、生命垂危到第一次爬出巢箱、自主站立、行走扑跳、淘气"炫饭"……两个月来，在西 宁野生动物园社交平台官方账号中，众多网友持续"追更"雪豹"凌小蛰"的康复日志，密切关注其体况改 善。 3月5日，6月龄重伤雪豹幼崽在三江源腹地、青海省玉树藏族自治州治多县野外被巡护员发现，及 时送往青海野生动物救护繁育中心治疗。目前，这只名为"凌小蛰"的雪豹身体渐渐好转，它将何去何 从、能否放归等话题持续引发讨论。 齐新章说："一只雪豹的生存活动需要相当规模的食草动物、草场支撑，它的种群健康于整体高山 生态系统而言具有典型指示意义。" 3月15日，救助人员为雪豹"凌小蛰"治疗。 (西宁野生动物园供图) 在连新明看来，雪豹作为三江源生物链顶端掠食者，具备科学研究、自然教育、文化传播等多元价 值。 "以几年前救助的雪豹'凌蛰'为例，它放归时佩戴的卫星追踪项圈，可用于观测记录迁徙路线。"连 新明称，"我们看到，它的活动范围很大，涉及多地超1057公里，这可能就是未来雪豹避开人类干扰的 栖息廊道。收集这些信息作为打造廊道的基础，从而保证雪豹栖息地完整性，让破碎片区的种群得以联 结、交流。" "应该说，救助和保护行动其实都是以人类 ...

记者 陈玺撼 王海燕）沿着浦东滨江岸线走到杨浦大桥下，一座2000平方米的花园映入眼帘，惊喜不止于此，池塘边的梭鱼 草中，一只市区里不多见的黄翅蜻正翩翩起舞……这是上海"一江一河"滨水区域首座生境花园"生境东岸"，昨天正式建成开 放。 留基底 将"生境"与"花园"融合在一起——这种具有生物栖息环境功能的花园有5个特点：使用本土植物，杜绝外来入侵植物，丰富 植物群落，减少农药化肥的使用，为城市野生动物提供辅助的食物、水源或庇护所。 "城市的快速发展不断挤压自然精灵的生息空间，是这片自然基底的顽强，唤醒了我们的责任感。"东岸集团党委办公室副 主任鲍伶俐介绍。此前的生物多样性调查在这里发现了14种鸟类、4种蜻蜓、5种传粉昆虫和20余种植物。"闹市"中蕴藏的这片 生机令人震撼，让管理者重新审视公共空间的功能性。 追求"生境"功能，就不能大拆大建，要营造更适宜已有"住户"繁衍生息的环境。大自然保护协会（TNC）上海保护项目总 监俞霖琳告诉记者，这片空间原有的水杉全部被保留了下来，在原有600多平方米人工水体基础上，净化水质、补种各类适应湿 地环境的植物，形成了这座生境花园的雏形。 造"跳板" 城市令原本连通的生境被割裂 ...
