| accessInformation:
|
Riparian vegetation data collated from field surveys undertaken by SEPA Geomorphology Staff and contractors for less than good water bodies, rest based on GIS analysis. Energy data based on will the river do the work. Then both layers have been combined to produce this layer following the method detailed in the description. |

Thus, the new layer identifies areas where:</SPAN></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN STYLE="font-size:12pt">- tree planting will benefit geomorphology through river restoration when morphological pressures were present in a particular section. Note: existing morphological pressures have not been included in this layer apart from riparian vegetation loss. Further work is currently being undertaken by SEPA to consider other existing morphological pressures. The mapped outputs of this work will be made available in due course and could inform more detailed project stages. </SPAN></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN STYLE="font-size:12pt">- and sections where lack of trees are exacerbating geomorphological process like bank erosion etc. </SPAN></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN STYLE="font-size:12pt">This layer classifies the cells into high, medium, low priority for riparian woodland planting. </SPAN></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN>This layer is for:</SPAN></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN STYLE="font-size:12pt">- Riverwood.

It is noted that site specific assessments would be required to inform individual projects, including with regards flood risk. </SPAN></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN>Method:</SPAN></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN STYLE="font-size:12pt">The layer makes use of the sections where the vegetation condition is poor or moderate for each bank (good condition and other habitats are excluded from the analysis) and sections where the recovery potential of the channel is high. E.g., if there were morphological pressures in that river reach, that section of river has the energy to self-recover of recover with assisted restoration, and riparian planting plays a role on that mitigation. </SPAN></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN STYLE="font-size:12pt">The scoring table is shown below, table adds the priority score for both elements:</SPAN></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN /></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN>Table</SPAN></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN STYLE="font-size:12pt">rows: Vegetation quality (score/priority) Columns: Energy for self-recovery (score/priority)</SPAN></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN STYLE="font-size:12pt"> Low (3) Moderate (2) High (1) RTC (1)</SPAN></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN STYLE="font-size:12pt"> Poor (1) 4 3 2 2</SPAN></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN STYLE="font-size:12pt"> Moderate (2) 5 4 3 3</SPAN></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN /></P><P STYLE="text-align:Justify;margin:0 0 11 0;"><SPAN STYLE="font-size:12pt">- High priority for riparian woodland planting (green): final score 2.
