NESH Section II, Part 400 ES Characterization Concepts Part – Purpose Part – Definition Part – Defining the ES Concept   Identification and characterization of ESs are based on the premise that:   composition, structure, and function of plant communities (and ecosystem functions) are regulated along energy, moisture, and nutrient gradients and disturbance regimes   Gradients occur due to differences in microclimate, geology, lithology, topography and soil characteristics Part – Purpose Part – Definition Part – Defining the ES Concept   Identification and characterization of ESs are based on the premise that:   composition, structure, and function of plant communities (and ecosystem functions) are regulated along energy, moisture, and nutrient gradients and disturbance regimes   Gradients occur due to differences in microclimate, geology, lithology, topography and soil characteristics

  Environmental gradients   Natural disturbance regimes   Environmental gradients   Natural disturbance regimes ES concept is based on reference conditions (Reference State) which formed as a result of interacting NESH Section II, Part Defining the ES Concept

Section II, Parts Part Interpreting Ecological Dynamics   Ecological dynamics describe changes to vegetation and soils, and the causes of those changes   State-and-Transition Models (STMs) illustrate ecological dynamics of an ES Part – Components of an STM Part Interpreting Ecological Dynamics   Ecological dynamics describe changes to vegetation and soils, and the causes of those changes   State-and-Transition Models (STMs) illustrate ecological dynamics of an ES Part – Components of an STM

Section II, Part Role of STMs   STMs are conceptual diagrams with narratives to describe:   Reference and alternative states,   Processes of plant community shifts within states,   Transitions between states, and   Restoration to a previous state.   The goal in producing STMs is to provide a conceptual understanding of:   Ecological dynamics that can occur on an ES   Drivers and mechanisms of ecosystem change   Management actions that can be used to influence change   STMs are conceptual diagrams with narratives to describe:   Reference and alternative states,   Processes of plant community shifts within states,   Transitions between states, and   Restoration to a previous state.   The goal in producing STMs is to provide a conceptual understanding of:   Ecological dynamics that can occur on an ES   Drivers and mechanisms of ecosystem change   Management actions that can be used to influence change

Section II, Parts Part – General Guidelines for Developing STMs   All states and community phases that are typical and known to occur should be described   Include “at-risk community” phases   Where time scales of community pathways or transitions are known, they should be described Part Recognizing a State Change Versus a Different ES   As long as the soil and physiographic characteristics remain unchanged, a new ES is not merited.   The inability to restore an alternative state to reference state due to lack of knowledge, technology, or cost does not warrant a new ES.

NESH Section II, Part 500 Steps for ES Differentiation and Developments of ESDs Purpose Differentiation and description of ecological sites (ESs) involve several steps: preliminary stages, iterative stages, and final stages.
