Reducing the risk of the introduction and spread of Invasive Non Native Species to and within the river catchments of Yorkshire and across GB.

外来入侵物种（INNS）是指由于人类活动而被引入其正常范围之外的动植物，它们对我们的经济、生物多样性甚至健康都有负面影响。水生生态系统（河流、溪流、湖泊）特别受国际生态系统影响，国际生态系统可能通过贸易、运输和娱乐等活动传播。根据英国非本地物种秘书处（GB Non - Native Species Secretariat）的数据，英国国家生物识别系统每年的成本约为17亿英镑。一旦在河流中建立了INNS，管理它们通常是困难和昂贵的。从一开始就阻止它们的引入，并防止已建立的INNS的更广泛传播，成本效益要高得多。这种预防被称为生物安全。良好的生物安全性以防止INNS的引入和传播是最近欧盟关于入侵物种立法和GB入侵非本地物种战略的核心要求。目的：本提案的目的是降低约克郡（中期）和英国（长期）水生INNS引进和传播的风险。我们将利用利兹大学最近的研究成果，并与来自政府、慈善机构和企业的项目合作伙伴合作，在合作伙伴组织以及更广泛的社区的日常活动中发展良好的生物安全实践。目标-确定国际生物安全威胁可能到达的主要入侵途径-为一系列活动建立良好的生物安全规范/协议-为事件/项目/地点/活动制定生物安全风险评估流程-推广和传播生物安全培训材料并评估吸收和有效性。我们的项目合作伙伴是：约克郡山谷酒店战略指导小组的成员：环境署（EA）、约克郡水务（YW）、约克郡野生动物信托（YWT）、约克郡山谷国家公园管理局（YDNPA）、尼德代尔杰出自然美区（NAONB）、自然英格兰（NE）、林业委员会（FC）、国民信托（NT）、约克郡山谷河流信托（YDRT）、里布尔河流信托（RRT）、山谷至河谷河流网络（DVRN）其他合作伙伴：约克郡入侵物种论坛（YISF），动植物卫生署（APHA）。该项目还得到了英国非本地物种秘书处的支持。我们从这个项目中设想的结果是双重的；1)项目合作伙伴采用的改进的区域生物安全实践；2)通过采用循证方法和政策改善国家生物安全。两者都具有降低引入和传播生物多样性和经济的风险和相关成本的影响

Invasive Non Native Species (INNS) are animals and plants that have been introduced (as a result of human activity) outside their normal range, and which have negative effects on our economy, biodiversity and even health. Aquatic ecosystems (rivers, streams, lakes) are particularly affected by INNS which may be spread by activities such as trade, transport and recreation. The cost to GB of INNS is ~£1.7bn per year (GB Non Native Species Secretariat). Once INNS become established in a river, it is often difficult and expensive to manage them. It is far more cost effective to prevent their introduction in the first place, and to prevent the wider spread of INNS that have established. Such prevention is termed biosecurity. Good biosecurity to prevent the introduction and spread of INNS is a core requirement of the recent EU legislation on Invasive Species and of the GB Invasive Non Native Species strategy. AIM The aim of this proposal is to reduce the risk of the introduction and spread of aquatic INNS in Yorkshire (medium term) and the UK (long term). We will use results from recent research at the University of Leeds and work with project partners from government, charities and business to develop good biosecurity practice in the day-to-day activities of partner organisations as well as the wider community.OBJECTIVES- Identify key invasion pathways by which INNS may arrive- Establish good biosecurity practice/protocols for a range of activities- Develop a biosecurity risk assessment process for events/projects/sites/activities- Promote and disseminate training materials on biosecurity and evaluate uptake and effectiveness. OUR PROJECT PARTNERS ARE: Members of the Yorkshire Dales INNS strategy steering group: The Environment Agency (EA), Yorkshire Water (YW), Yorkshire Wildlife Trust (YWT), Yorkshire Dales National Park Authority (YDNPA), Nidderdale Area of Outstanding Natural Beauty (NAONB), Natural England (NE), Forestry Commission (FC), National Trust (NT), Yorkshire Dales Rivers Trust (YDRT), Ribble Rivers Trust (RRT), Dales to Vale River Network (DVRN) Other partners: Yorkshire Invasive Species Forum (YISF), Animal and Plant Health Agency (APHA). The project also has the support of the GB Non Native Species Secretariat.OUTCOMES The outcomes that we envisage from this project are twofold; 1) improved regional biosecurity practice adopted by our project partners;2) improvement of INNS biosecurity nationally through adoption of evidence informed approaches and policy.Both have the impacts of reducing risks and associated costs to our biodiversity and economy of INNS introduction and spread
