较低的哥伦比亚生态系统管理计划（LCEMP）是一种协作方法，可在不列颠哥伦比亚省下哥伦比亚地区进行评估，康复，监测，保存和增强野生土地生态系统。LCEMP出现不需要Tect，以解决在TRAIL运营周围的一部分地面生态风险评估（ERA）研究区域的生态影响。LCEMP是Teck，监管机构和其他利益攸关方之间的合作，以满足受污染地点规定的监管要求。

The objective of this landscape-level plan will be to enable landowners and project funders to implement habitat restoration, improvement and conservation actions that act together to maximize ecosystem integrity and habitat connectivity for a broad range of biodiversity.

The larger LCEMP boundary area (with the ERA area of interest nested within), encompasses the lower Kootenay and Columbia River valleys from Grohman Narrows near Nelson south to the border. This boundary emphasizes valley bottom and low elevation areas in the Interior Cedar Hemlock biogeoclimatic zone. Projects in this broader area may be considered, particularly for those lands that require offsetting to address historical sulfur dioxide impacts, to take advantage of the best biodiversity opportunities.

The guiding principles developed for LCEMP are:

• 该计划将专注于生态价值观和相关影响
• 该计划将考虑栖息地管理对周边地区的社会经济和文化福祉的影响
• 该计划将争取利益攸关方之间的共识，同时承认土地所有者和法定权利和责任
• Management actions will cause “no net harm”, and are intended to yield a net benefit, as confirmed through effectiveness monitoring and adaptive management

Realistic remediation and risk management options to address ecological risks include:

• Ecosystem rehabilitation through soil amendments and/or silviculture treatments (e.g., prescribed fire, selective tree thinning)
• Natural attenuation/regeneration and monitoring
• 栖息地或栖息地元素库存，保护，增强或创造（在高地，湿地和河岸设置）
• 建立野生动物巢或栖息盒，平台，小屋，贵族，晒太阳网等。
• Weed inventory and control of species not designated as noxious
• Forest health and disease management, research and monitoring
• Access control and use restrictions and monitoring
• Listed animal or plant species inventories, research and monitoring
• Interpretive signage or public education/awareness initiatives
• Establishment of conservation covenants, stewardship agreements or other conservation approaches

年代tudies of wetlands as a follow-up to the aquatic ERA study are also being completed under the review of the LCEMP Steering Committee.

2008 Terrestrial Ecological Risk Assessment

From 2000 through 2008, Teck conducted an ecological risk assessment in the Trail area. The purpose of the study was to identify where there are past or ongoing impacts on the environment due to historical smelter emissions. As the study progressed, we continued to address obvious known problem areas (e.g. remediation of historic waste storage areas near Stoney Creek and re-vegetation of barren ground, particularly close to our Trail Operations).

该研究的陆地部分得出结论，从环境中与冶炼有关金属的动物有害影响的风险很小，但由于过去损害了植物群落的危害，野生动物栖息地存在残余影响。如上所述，LCEMP正在解决这些影响。
