2006-2007 Cutblock Level Soil RSM Pilot
Results
Sandy Currie Soil Resource Value

2
Cutblock LevelMonitoring Indicators
Lost productivity due to access construction
In-block area affected or potentially affected by landslides, drainage diversion (overland flow), or significant erosion
In-block area affected by disturbance to natural drainage patterns resulting in water accumulation
3
Cutblock LevelMonitoring Indicators
Dispersed soil disturbance in the net area to be reforestedGreen tree retentionOrganic matter retention
4
Protocol ToolsGeneral
Use of high quality digital photography as the primary means of analyzing the impact of harvesting on a random sample of cutblocks
Use of ground sampling as a means of checking the reliability of the digital photography methodology
5
Protocol ToolsApplication
The digital photography is analyzed to assess the impact of harvesting on each of the six identified Indicators
A line transect sampling method is used in the field to provide an on-the-ground check of the digital photography results
6
Protocol ToolsApplication (cont.)
During this final pilot year field sampling was set at 100% of the cutblocks that are sampled using the digital photography methodology
During the first year of implementation (2007-2008) 100% of the digital photography samples will once again be field-checked
7
Expected Results
The target for this year’s sampling was to:Take and then analyze digital photographs of approximately 80 cutblocks throughout the province
Conduct field assessments on these same 80 cutblocks
8
Expected Results (cont.)
Training in conjunction with the sampling comprised:
One training session that was held in Prince George December 5 – 8, 2006
9
Actual Results
Digital Photography:Of the 15 districts that were planned for photography 11 were either fully or partially completed and the remaining 4 were not completedThis resulted in processing, or completing a mosaic of, the digital photography of 50 of the planned 80 cutblocksThese 50 images are currently being simultaneously analyzed and the data captured by Selkirk College staff (principal analysis centre) and district forest stewardship staff
10
Actual Results (cont.)
Field Sampling:
Field sampling of all 80 sample cutblocks has been completed and these data will be compared to the associated photographic images
11
Next Steps
Digital Photography:
Analysis will be completed on the 50 digital photographs
The resulting data will be captured and cleaned and sent to Victoria
12
Next Steps (cont.)
Field Sampling:
The remaining field data that have not already been sent to Victoria will be captured and cleaned and sent to Victoria
13
Next Steps (cont.)
Analysis:
The digital images and field data will be:
compared to assess the accuracy and capability of digital imagery as a FREP sampling tool
14
Next Steps (cont.)
FREP Final Report:
The results of the 2006-2007 aerial photography and field sampling will be used to prepare a final report on the 2006-2007 Cutblock Level Soil Pilot
15
Next Steps (cont.)
Lessons Learned:
Administrative pre-work must begin enough in advance to ensurethe 2007-2008 digital photography program takes place during the best weather conditions
16
Next Steps (cont.)
Preparation for 2007-2008 Aerial Photography:
Seventeen districts comprising 80 cutblocks have been randomly selected
An Invitation to Tender is in the final revision stage and will be posted on BC Bid by March 15, 2007 to allow a viewing period of 6 weeks
The targeted date for the start of aerial photography is May 22, 2007
