Good Management Practices in Forestry
Reducing Diffuse Pollution from Forestry Related Activities in
Galloway and
Eskdalemuir Forests
John Gorman
Senior Environment Protection Officer
Project Aims
• Improve Communication links with State and private forestry –
liaison meetings
• Workshops, awareness days, training & site
visits, shared learning
• Site inspections –clearfelling, restocking, drainage works,
road construction, quarries,
pesticide/herbicide/fertilisers applications
• Help develop Best Practice Guide for forestry activities via
DPMAG
Main Problems
• Siltation from ground preparation, cultivation, harvesting and
restocking
• Contaminated run-off from roadways
• Historical drainage systems
• Standing sales
• National disease obligations versus FWG5
• Quarry runoff
• Natural Regen
• Waste
Forestry Commission fined £24,000 for Powys pollution
Soil and silt disturbed by heavy machinery strayed into a brook
near Llanwrtyd Wells “Start QuoteWe are therefore extremely
disappointed that we fell short of these standards on this occasion
but we have taken action to prevent this happening again”End Quote

Roadside DrainCHRONOLOGICAL DRAINAGE REVIEW
• FWG2, 1991 [23 Years ago] prevent roadside drains discharging
direct to watercourses; where unavoidable provide silt traps
andmaintain them regularly.
• FWG3, 1993 [21 Years ago] Roadside drains carry high sediment
load must not be allowed to directly connect to watercourses,
re-direct to buffer areas
• FWG4, 2003 [12 Years ago] Old drain clearing presents high
risk of pollution, drains should be realigned to ensure volume
flows onto vegetated ground and NOT into watercourses. Existing
drains should not drain directly into watercourses
• FWG5, 2011 [3 Years ago] Realign existing drains, avoid
watercourse connections, redirect to buffer zones

SUMMARY
• Quality Site Pre-Planning, Work Plans-Pull out flow chart of
key decisions & tick list ?
• Notebooks for machinery Operators
• Think Source-Pathway-Receptor
• Pollution prevention NOT remediation
• Contingency check list eg Stockpile of
materials on site, oil pads, contact lists ?
• Dummy copies of Plans for reference ?
