Protected Zone Plots Additional GB 10K Grid 2014

Survey sites used to confirm the absence/presence of bark beetle species, Pinewood Nematode and Pitch Pine Canker.

The PZ plots defined by this set of data reflect a proposed 2 year, annual survey as described. Some of these plots sites may be taken up in the ongoing permanent PZ plot surveys. Additional Temporary PZ plots may be located in response to incidents.

Survey undertaken includes visual inspection and destructive sampling and included baited (pheromone lure) log traps. The location of the Survey plots is determined on a risk based approach, positioned in proximity to major timber processing sites, transport hubs (railheads) or points of entry (ports).Spatial data used for the analysis, using FC SCDB and NIWT. Plots set up in early summer 2014, visual surveys and sample collection repeated at 8 week intervals.

本数据集涉及的调查地点旨在确认树皮甲虫物种、松树线虫及松树树脂病的发生与否。该数据集中定义的PZ图则反映了为期两年、年度性的调查计划。其中部分调查地点可能被纳入正在进行的永久性PZ图调查之中。根据事件响应，可能还会增设临时PZ图。调查内容包括视觉检查和破坏性采样，并采用了诱饵（信息素诱饵）的圆木陷阱。调查图点的位置基于风险评估，位于主要木材加工地点、交通枢纽（铁路起点）或入口点（港口）附近。分析中使用的空间数据来源于FC SCDB和NIWT。调查图点于2014年夏季早期设立，视觉调查和样本收集以8周为间隔重复进行。计数：网格方格内调查地点的数量。年份：调查地点的调查年份。归属声明：包含OS数据©[年份]英王版权[及数据库权利]。
