Multispectral mapping of vegetation changes in reclaimed areas at Highland Valley between 2001 and 2011 Brown, Leslie N.; Borstad, Gary A.; Dickson, Jaimie; Martell, Peter; Martínez de Saavedra Álvarez, Mar
Abstract
Airborne remote sensing has been used at Highland Valley Copper since 2001 as part of the reclamation program to provide annual high spatial resolution maps of vegetation cover and complement the vegetative assessments. In 2011, the multi-temporal analysis was applied to all sites undergoing reclamation, with the exception of Valley and Lornex, where mining operations have been extended to 2025. As in previous years, Remote Sensing biomass was calculated based on the Normalized Difference Vegetation Index (NDVI) and then appended to the existing NDVI time series. This unique and growing dataset allows us to examine vegetation changes over time with spatial resolution of 2.5m. We can now classify the entire mine site according to its vegetation history and whether or not it has reached and maintained biomass above 1500 kg/ha, which is one of the permit thresholds for selfsustaining status. The resulting 'reclamation status maps' provide a detailed synopsis of the vegetation trends between 2001 and 2011. These maps are designed to be helpful tools to reclamation managers, as they provide a means to focus further remediation efforts on specific locations most needing it, rather than having to make costly wholesale changes to entire sites.

Airborne remote sensing has been used at Highland Valley Copper since 2001 as part of the
reclamation program to provide annual high spatial resolution maps of vegetation cover and
complement the vegetative assessments. In 2011, the multi-temporal analysis was applied to all sites
undergoing reclamation, with the exception of Valley and Lornex, where mining operations have
been extended to 2025. As in previous years, Remote Sensing biomass was calculated based on the
Normalized Difference Vegetation Index (NDVI) and then appended to the existing NDVI time
series. This unique and growing dataset allows us to examine vegetation changes over time with
spatial resolution of 2.5m.
We can now classify the entire mine site according to its vegetation history and whether or not it has
reached and maintained biomass above 1500 kg/ha, which is one of the permit thresholds for selfsustaining
status. The resulting 'reclamation status maps' provide a detailed synopsis of the
vegetation trends between 2001 and 2011. These maps are designed to be helpful tools to reclamation
managers, as they provide a means to focus further remediation efforts on specific locations most
needing it, rather than having to make costly wholesale changes to entire sites.
