红树林的恢复应该比灾难性损失的时候早得多。我们描述了“红树林心脏病发作预防”的必要性，以及如何通过在海岸管理计划中嵌入地块和遥感监测来实现一般意义上的预防。全球许多地点红树林紧张的主要原因往往与潮汐流量和交换减少有关。水流受阻不仅会减少向海一侧的冲刷，而且当水流向陆地受阻时，还会导致盐度升高和沉积物减少。长期的功能退化会导致急性事件引发的急性死亡，但这是由于长期忽视红树林的系统性倾向造成的。通常，红树林在几年内就消失了；然而，几十年前，当进行了看似无害的水文修改(例如，道路建设、堵塞的潮汐水道)时，脆弱性被重新设定，但在没有合理的大规模监测的情况下，仍然没有被发现。(C)2016爱思唯尔有限公司。保留所有权利。
Mangrove forest rehabilitation should begin much sooner than at the point of catastrophic loss. We describe the need for "mangrove forest heart attack prevention", and how that might be accomplished in a general sense by embedding plot and remote sensing monitoring within coastal management plans. The major cause of mangrove stress at many sites globally is often linked to reduced tidal flows and exchanges. Blocked water flows can reduce flushing not only from the seaward side, but also result in higher salinity and reduced sediments when flows are blocked landward. Long-term degradation of function leads to acute mortality prompted by acute events, but created by a systematic propensity for long-term neglect of mangroves. Often, mangroves are lost within a few years; however, vulnerability is re-set decades earlier when seemingly innocuous hydrological modifications are made (e.g., road construction, blocked tidal channels), but which remain undetected without reasonable large-scale monitoring.
