The Bednesti site preparation study, located in the SBSdw3 biogeoclimatic
variant of central British Columbia, examined lodgepole pine response
to various types of site preparation from 1988–2017. In addition to
tree measurements, climate and microclimate data were collected to
characterize important environmental parameters such as air temperature,
soil temperature, soil moisture, precipitation, and solar radiation that
could assist with the interpretation of pine survival and growth responses.
Although various publications have sometimes referred to the climate
and microclimate data to help interpret specific tree or vegetation
responses, no single publication has focussed on the environmental data or
comprehensively examined possible correlations with tree growth. Although
it is difficult to draw firm conclusions regarding such relationships due to
limited replication of some of the climate and microclimate measurements,
trends can be identified that suggest avenues for further research.
