Sensitive Ecosystems

Sensitive ecosystems are often remains of the natural ecosystems that once occupied a much larger area and are increasingly important as human activities change the landscape. These ecosystems are rare, ecologically fragile, or at-risk. The City of Abbotsford is classified as the South Fraser and contains the highest percentage of on many of the region's Modified Ecosystems - about 50% of the regions freshwater reservoirs, old field, seasonally flooded agricultural fields, and young broadleaf forests.敏感生态系统（Sensitive Ecosystems）通常是曾占据更广阔范围的自然生态系统（Natural Ecosystems）的残存片段，在人类活动持续改变地表景观的当下，其重要性与日俱增。这类生态系统往往较为稀有、生态脆弱或处于濒危风险之中。阿伯茨福德市（City of Abbotsford）被划归为南弗雷泽（South Fraser）区域，拥有该区域占比最高的诸多受损生态系统（Modified Ecosystems）——约占该区域淡水水库、老撂荒地、季节性淹水农田与幼年阔叶林总面积的50%。
