Threats Identifying actual and likely threats to the ecological character of the site helps guide future management planning and action. Those threats that pose a significant risk to the critical components, processes, benefits and services of Lake Albacutya are summarised below in Table E4 and the most significant threats are discussed further in the subsequent text.
