Silvatech was responsible for environmental compliance monitoring, mussel surveys, blasting auditing and turbidity containment on road extension into Skaha Lake, near Penticton, BC. The project also included fish capture and recording, mussel relocation with tagging and reconnaissance of alternate mussel habitat. Follow-up monitoring will be executed in 2013 and 2014.
Silvatech is responsible for environmental compliance monitoring, new channel design for no-net-loss of fish habitat with in-stream fish structure installations and re-vegetation of stream banks on the re-alignment of Hwy. 6 at Coldstream, near Vernon, BC
Automated Water Feature Delineation from Lidar Data
Information on the location and extent of water and wetland features is essential for many applications, including various aspects of environmental planning and management. Accurate mapping of water feature information is often costly and time consuming as it is typically labour intensive.
The sample to the right exemplifies a project involving an innovative water delineation procedure developed by the Silvatech - Earth Imaging group, based on lidar data collected with the FUGRO FLI-MAP system, over-layed on orthophotography. This approach features a very short turnaround time.
Silvatech has also developed procedures to take advantage of the unique aspects of multi-spectral imagery and lidar data, enabling direct detailed delineation of water features present on the landscape at the time of data collection. The result is a timely, accurate, low cost solution for extracting water features.
The Silvatech Group has been working with the Government of Alberta providing land base information supporting Regional and Sub-Regional planning. Silvatech uses a suite of tools to provide insight into the potential implications of alternative land management strategies. These have been applied in the Lower Athabasca, the South Saskatchewan and the North Saskatchewan Regions.
Included in this suite of tools is a Geographic Information System and landscape cumulative effects models, including the ALCES® model, to provide insight into the potential social, economic and environmental outcomes of alternative land use management strategies. Our analysts have been bringing their experience together with the Land Use Secretariat and several Provincial Ministry and other sector representatives to populate these forecasting tools and apply them iteratively to find optimal solutions to land use challenges.
We are now working with the Government of Alberta to examine sub-regional assessments that will inform planning at the tactical level as the Land Use Framework is implemented on the ground.
Silvatech developed several Total Chance Harvest Plans (TCHP) including the Ducette operating area, Prince George Business Unit, British Columbia, Canada for British Columbia Timber Sales (BCTS). The plan is one of thirteen carried out by Silvatech over a 3 year period. It encompassed over 17,000 ha that had only seen limited historic harvest related activity.
Using soft copy stereo technology, Silvatech identified all harvesting opportunities and identified the optimal location of all transportation infrastructure requirements for the entire operating area. This plan was verified and /or modified with supplemental, targeted field reconnaissance providing additional validity to the plan.
The plan afforded BCTS the flexibility to accommodate for other non-timber resource values by having complete knowledge of the operating area and the relative merchantability of respective harvest areas. It entailed carrying out a merchantability analysis for the Ducette area incorporating the costs and values associated with each harvest unit. Road construction, silviculture, harvesting, log transport, manufacturing, overhead, and road maintenance costs were all incorporated into the cost structure of each individual harvest unit. These costs were offset by the stand value extrapolated from stand composition and site characteristics. The resulting merchantability value, combined with the TCHP product, provided planners a detailed information matrix in which to base future land base management decision.
