Ground Water Dependent Terrestrial Ecosystems

GWDTE are a range of habitats influenced by ground water. GWDTE are wetlands which critically depend on groundwater flows and/or chemistries. As part of the assessment of groundwater status, we are required to assess if a GWDTE has been significantly damaged and if the pressure causing this damage has been transmitted via a groundwater body.

This course aims to look at the ecological requirements – habitats and species, relationship to ground water hydrology, chemistry and geology and will examine the factors to be studied to understand the complexity of these systems. This will include GWDTE functions and references:

• SEPA GWDTE habitats review
• Desk study – existing hydrology, hydro-geology, geology, topography, aerial photos
• Site visit – chemical analysis, topography, ground trothing drift/solid geology – control samples
• Assessment – include value of GWDTE and Annex 1 habitats
• Potential or Actual GWDTE?
• Mitigation/Monitoring requirements
• Phase 1 Habitat and NVC Quadrat data
• Site preparation and procedures
• Methods and preparation (record cards, frequency and Domin values)
• Plant identification and species indicators for habitats
• Analysis of quadrat data and interpretation of Phase 1 and NVC data

Consultants, SEPA, Water Authorities, Hydrologists, Aquatic Ecologists and Freshwater botanists. Relevant to all UK.
