This field guide presents site classification and identification information for ecosystems of the southern Thompson--Okanagan areas in south-central British Columbia. It provides new forest and non-forest site classification for the following existing and newly mapped biogeoclimatic subzones/variants: BGxh1, BGxh2, BGxw1, PPxh1, PPxh2, IDFxh1, IDFxh2, IDFdk1, IDFdk2, MSdm2, MSxk1, MSxk2, ESSFdc2, ESSFdh1, ESSFmw1, ESSFxc1, and ESSFxc2, This field guide replaces the biogeoclimatic and site classification previously published for the former Kamloops Forest Region in Land Management Handbook 23 (Lloyd et al. 1990) for geographic areas covered by the new field guide. This field guide is being released with a new provincial biogeoclimatic ecosystem map for British Columbia (BEC version 12). Changes to mapping cover the areas described in the field guide and apply to the Merritt Timber Supply Area (TSA) of the Cascades Natural Resource District, the southern portion of the Thompson Rivers Natural Resource District, and the western portion of the Okanagan--Shuswap Natural Resource District. The new classifications and mapping provide important baseline ecological conditions for natural resource conservation and management, including forestry, the environmental assessment process, and assessing potential effects of climate change and the cumulative effects of management activities. This is an interim version that will be replaced by the final published version that is expected to be released by April 2022.
