Environmental Targets and Priorities
A fundamental premise used to develop the NPS Plan 2005-2010 is that to have meaningful, rational, quantitative environmental targets and priorities, they must be developed from data about baseline or "as is" conditions. Management to achieve and maintain environmental quality depends on understanding and integrating the linkages between current environmental conditions and stressors. Therefore, this section of the plan focuses on the current and desired water quality outcomes or responses resulting from Ohio nonpoint source control implementation. Particular emphasis is placed on the key stressor and exposure indicators that must be addressed to achieve those outcomes or responses.
This represents a conscious and deliberate paradigm shift from a previous focus on using the quantity of management practice implementation as a performance indicator to classifying management practice implementation as an administrative indicator and adding other types of indicators to illustrate progress. This integrated approach to measuring and achieving environmental quality is detailed in a hierarchy of indicators.
It is important to note that categorizing and sub-dividing environmental targets and priorities into chemical and stream integrity does not negate the need to integrate the two when making environmental monitoring, assessment and management decisions.
OVERVIEW "AS IS" SITUATION
CHEMICAL INTEGRITY TARGETS
STREAM INTEGRITY focuses on the major
causes of stream integrity impairment, habitat
modification and hydromodification, leading to fundamental changes to key stream features.
FUTURE ACTION ITEMS summarizes issues and ideas for further refinement of
existing targets and additional future targets.
